Yeah you could be right with this. I didn't use my head enough to end up with explanation like this, of course this is possible. If inlet valve is always open and there is oil coming in the oil will get everywhere.
I'm interested to hear the compression results when you have them.
The amount of oil in the intake side, it's hard for me to say anything since I haven't seen the case. But I suppose there shouldn't be any at all.
Throttle body and pretty much everything on the intake side are often dirty because of the recirculating breather system, but if you saw fresh oil in the inside piping it doesn't seem normal to me. Are you still sure this isn't the way of oil getting in?
Maybe the oil over the valve cover and oil getting in to the engine is a separate issue, but they could be related too.
I myself would probably start by doing the breathing check from the "oil hole" (lol what is the correct English term for it).
After that I would open the valve cover and check if everything seems ok there.
I would also check everything what has something to do with the engine breathing and also "convert" it to atmospheric since it's a lot simpler system. Tho I dunno if this is allowed, or are you going to get problems at MOT.
Hard for me to say anything more really.

At least in the video the smoke looks blue, I would say it is oil indeed.
But the explanation of how it have entered your engine/exhaust seems to get more complicated.
But you said that there is oil in places where it isn't supposed to and if it isn't because of the valve cover then I started thinking about pressure.
There is some kind of a breather system from the crankcase and maybe from valve cover too. If for instance the crankcase breather gets stuck it could increase the crankcase pressure and results could be oil in the wrong places. All that pressure is going to find a way of releasing itself.
I dunno what kinda breather system this Toyota engine has but usually it's somehow recirculating, when the engine breaths pressure out the dirty air is usually leaded back to the intake.
Are you sure the oil what has come out hasn't simply entered in to the intake and gets to the engine like this? This could be caused by faulty breather system and should be very cheap to fix and even easy if you don't mind about keeping it recirculating.
TBH I'm glad my engine isn't part of the green-movement and breaths simply to the atmosphere.
Also if engine just simply breaths a lot it means piston rings are worn. In most engines this could be checked by removing oil gap from valve cover and when engine idles keep your hand over the hole, if engine breaths excessively you can feel it in your hand by the air moving a lots.
And BTW if piston rings are worn or in general pretty much everything is worn it doesn't always mean you could tell it by your "butt-dyno". It's surprising how well even a worn out engine can perform sometimes and TBH some people have better butt dynos than some.

Yeah seems like you can't always trust the basic "smoke color code".
BTW about the Cologne and it's power, some could say it's an interesting product. For instance when the Sierra XR4i 2.8 was released they promised 150bhp and 8.5 seconds 0-100 km/h (or 0-62 mph) times and the cars what most car magazines test drove did this and were described as powerful sporty-like cars. But differences between cars what ended up to the actual customers were huge and actually most of them weren't any faster than the 2.0 injected models with ~10 seconds times to 0-100. Only difference was heavier engine at front and more torqueish nature.
So it's not actually that surprising that the one Cologne you had did better than some.

Yeah I started to think of it and that also came up to my mind, might be the turbos. I just don't have any fact how the smoke should look then.
Ah so it's a Toyota motor then. Well can't really say this enlighted me in any way since I'm not that familiar with them.

I'm turning my head a bit here.
After doing more research it seems that when oil smoke is white it isn't burning, it's evaporating, similarly to water. Combination of lots of oil and less oxygen and the oil wont burn, it just evaporates in the heat. Maybe it's not turning in to smoke in the combustion chamber but is just pushed in to the hot exhaust and evaporates there then. Or the amount is just so high it can't burn properly even in the engine.
I read a good example of F1 engine failures, there is usually a big amount of white smoke, but it can't be water because the smoke hangs around for a long time. When engine fails there is lots of oil pouring in to the exhaust and thus evaporating oil = thick white smoke.
But I'm still not sure.
-EDIT- Forgot to add, actually when I've seen engine failures with big thick white smoke clouds, I recall it being a big white cloud with blue lining (not silver).

What kind of engine is this? Because I don't seem to be able to come up with an explanation of how valve stem seals should let water/coolant in to the combustion chamber. Normally valve stem seals aren't in any kind of contact with water. Or how oil would burn as a white steam.
-EDIT- Now if I think of it when oil is burnt lots it can make a thick white smoke, I've even seen it happen I think. It's just usually when valve stem seals are hardened or worn the amount of oil isn't big and results are different. Some race engines even don't use any valve stem seals at all and the smoke what comes out is blue.
-EDITEDIT- Tried to do some research, I simply hate when things like this don't get a perfect answer or I can't make it myself. Seems like it maybe doesn't have anything to do with the amount of oil burning if it's blue or white, but dunno. There just doesn't seem to be any explanation what causes oil burning white. Only the usual forum posts of people asking about their smoking cars and then people telling them the basic rule, blue = oil, white = water, black = hella rich AFR and then the occasional yes oil can also burn white. But no I want the friggin physical explanation for this.

Erm white smoke / steam isn't usually a sign of any kind of fault. Pretty much every car does this when it's cold and moist. It's just water.
If your valve stem seals are gone it usually allows for oil to leak in to the combustion chamber and burn in engine, this results in blue smoke. Oil burns always blue. And the condition has to be really bad if it doesn't stop at all, or there is some other reason for burning oil.
If there is continuous white smoke coming out of the exhaust always, this could mean you have a head gasket or even head failure, which allows for coolant water to leak in to combustion chamber and thus vaporizes out of the exhaust. If this is the case and you have proper coolant (not just only water) your exhaust gases should smell weird, the smell would be sweet, "sugary", non "exhaust-gas" like.

Hard to say how high the snow could be if I wouldn't drive it occasionally and no one would plow the snow away.
The pile you see behind my car is now a lot higher. This and last winter has been really great after few of not so cold and much less snowy winters.

Oh hi.
Computer case is ugly old mATX, hardware inside:
Corsair 400W PSU
MSI K9VGM-V motherboard
AMD Athlon 64 X2 6000+ (slight overclock)
Mushkin 2x1Gb DDR2 800 memory
Gigabyte Radeon HD 6850 1024 GPU.
Gonna update hardware later, expect the GPU.
Steering wise, Logitech G25 and as a handbrake old Logitech joystick.
And a new screen, which is actually a telly, LG 32" LCD TV, it's main resolution is only 1360x768 but I still love driving sims with it.

Now where is that rally crash video where a Lancia Delta Integrale does pretty much the same. Crashes and after tries to continue but rear suspension starts bouncing like hell.
I had it on VHS rally crash video compilation when I was little and I'm pretty sure I have seen it at youtube as well.
Yea I do tons of sound modding to rFactor, currently I'm just finishing a personal mod what changes all of the sounds of the HistoriX mod. Using samples like in rFactor has it's pros, but it's real hard work since every sample has to match to each other, even a tiny mistake with RPM info for the sample and the miss match between transitions sounds horrible.
But LFS ain't bad also I think, it doesn't use audio samples but after some tweaking I have ended up with quite nice sounds for almost every car. Only the flat engines seem to give me problems, can't really get a natural sound out of them.
Sorry, getting a bit OT here.:talktohan

I own injection car nowadays but when I used to have carburetted car I always did three fast pumps before turning the key, at least when engine was cold. I think most carb manufacturers recommend this and if I remember correctly it even was in the car's original manual. Tho when I first started it I think it was my dad who told me to do it.
Yeah I'm into "old skool" Fords and Lotus Cortinas, Lotus Escorts (Twin Cam) are one of my all time favorites. It's hard to find good footage of these, especially the Cortina, most of them probably sit in garage quite a lot and when driven, usually quite carefully. It's understandable but quite of a shame at the same time. Good thing there is Historic racing.
Moar similar awesomeness http://www.youtube.com/watch?v=985bWl2s3lk
It's a bit shame that this video stutters a bit and ending for the battle was quite disappointing but still enjoyed it. It was quite funny to see the Cortina in lead with bunch of V8 cars following it waiting for opportunity.
Well usually with any type of carb/carbs you do the few pumps before starting and when starting apply lightly some gas, or in many cases even press it fully on and just release it when it starts. This also gives the very impressive revving starting style to impress other people in the gas station.
In the videos it just seemed like you simply just put the keys in lock and turn them but I guess that's not the case then.
Yes the problem is that when you shake in a car, you feel it, you don't see it. It doesn't affect your vision at all and I think this has something to do how brain use the vision and equilibrioception (the feel of balance, G-forces etc) together and so what you see is always steady.
In rFactor there are some weird effects but that is just the reason why you disable them.
Dunno about GT5 but at least in other sims I play the bumpiness of road is feelible thru FFB and simply just how car acts when driving at them and it's really easy to tell. This is proper feedback from the game instead of using effects.
Also the shaking effect in GT5 doesn't seem to have any real connection with the bumpiness of road, it's just a simple effect what keeps showing when the grip limit is near or you're already past of it.
Of course these things are matter of a taste but I find effects like this very irritating and pointless even.
BTW I'm quite sure GT4 also had a similar shaking effect in bumper cam, it's the last console game I've bought.
Probably one of the reasons why I feel bumps without effects like this is because I'm able to "sink" in the sim very well. In some weird way I even feel the G-forces, it's a trick what my brain does when concentrating really hard and driving as fast as I can. I notice this because sometimes during cornering a fast corner, especially the long ones, I get a feeling like I have to press the accelerator harder. I'm sliding a bit left or right and back even if it seems physically impossible, it makes keeping accelerator down harder and even affects my upper body. This is one of the reasons why I hate shake and g-force etc. effects in sims, they actually kill this "trickery" for me, I'm unable to sink in.

I'm thinking something like this. Ban wings and pretty much anything what makes downforce, so they have to rely on mechanical grip. Ban pretty much everything electronical beside the injection and ignition system. Also no turbos or any other way of charging, so we will end up with N/A engines. No KERS. And then most importantly make the engine design more free so there could be bigger engines in V, flat or straight form.
Could be interesting.
Oh and also include Nordschleife in race calendar.
Yes I know never gonna happen.

I'm not 100% sure of this but I remember reading somewhere that 10k potentiometers don't fit to G25, it uses better ones as stock and the ones it uses are usually a lot pricier.
Even in the slower cars I think the shaking is very visible. I myself usually use incar camera without any G-force emulations or effects whatsoever so these camera movements annoy me quite easily. For me it's easiest to "feel" the movement of car with solid camera, because then the visible movement is the actual car moving, not the camera.
-EDIT- This video shows the shaking and weird camera movement quite clearly http://www.youtube.com/watch?v=NoP38704tuc
Seems like camera shakes always when the car goes near or over the limit.

Yea gotta agree with the editing, especially the audio, there is no weird overlaps / miss matches easily audible in video and it has been sampled quite beautifully. But at least for me still it is easy to spot, there are parts where the audio is doing 200 km/h ++ and then suddenly it starts to shift down and the speed is very low, just doesn't seem right. Or when in video I can clearly see the car is on straight doing 80-100 km/h tops, but the audio is from a Ferrari doing again something 200+ flat out.
Tho I'm probably better than average hearing this stuff since I'm very passionate about engine sounds and a really big amount of my free time involves engine sounds in some way. So the average person probably would have more hard time trying to figure this video out. Only way I can enjoy a racing / driving video of some sort is if it has original, good quality audio.
I actually did a fast research after my post and how I understood it was a big Mercedes, but the roads weren't closed so it was actually illegal. But I dunno.
Dunno really, if I would've had the choice, I'd probably never went to army, but still now after it's over I think it would suck to not have the memories of it. Even if it mostly sucked to be there. I had some nice experiences, probably one of the best was when I had the chance to drive a real tank. It was only an old Russian BTR-50, but still. No brake pedal, only the brake levers on both sides and a huge non-syncronised gearbox on back, gear pattern reversed vertically for what we are used to, double clutching necessary + when downshifting throttle blipping and still getting gears in was one hell of a job with the nice sound of gear teeths banging against each other. Also the need of adjusting the "curtain" for the cooling system to keep engine at optimum temp meant that sometimes you had to drive blind for little time while lowering the drivers bench to reach the adjusting lever. Also the engine was a N/A 19.1 liter straight-6 with no any silencers at the exhaust, it pretty much only had the exhaust manifold exiting straight from the deck. As you may guess this means it made quite of a spectacular noise. It was actually the best sounding engine in service, even the turbo 47,6 liter V12 of Leopard tanks didn't sound so mad than the "puny" 250 or so bhp BTR-50. The sound is so loud that you have to be there to even be able to imagine it. Even at idle it makes a BIG noise, I once was for maybe one minute without ear plugs in the "cabin" near the engine while it was idling and after that pretty much lost the half of my hearing for the next 10 minutes. And this was only the mechanical noise it made (valves etc.), exhaust isn't audible when inside the thank. Oh BTW my own car pretty much idles where this 19.1 Diesel has it's best usable RPM range.
Went rambling about then I guess.
