What do you thinks wrong here (video) new link

There she is smoking it's head off

https://youtu.be/D7NVJki4CLw

Looks more like white smoke to me. could be condensation, dous it still do it after a long drive once warm?

Is it losing water/coolant?
If so id say water side of turbo as ive experienced this before, or headgasket.

If it was rings or valve stems it would be blue smoke also turbo.

May just be video quality but deffo looks white smoke?

Doesn't use anywater mate but she does use oil full on the dip stick to low on the dip stick in just 20miles there's oil getting into cylinder 3 you can see it on top of the pistion plus every ten mile you need to take the plugs out and clean them as the oil clogs up plug 3 an runs on 3 cylinders till it's clean then good for another ten mile

Ahh so oil is actualy in your cylinder?

Ok that points to a knackerd ring or a cracked ring land :/

Also is your plug seal on you rockor cover leaking & oil is running down past your plug in to your cylinder? I cant see it as you say it takes 20 mins to collect oil but if oil is thin then it maybe?

But sounds like a ring land or a ring. Do a compression check then that will tell you something is wrong

Compression test has been done 150psi across all 4 plug seal on rocker cover gaskets good yeah the cylinder no3 has oil on top of the piston

Still if there is oil in cylinder I think it can give you a false compression reading? Im not sure then mate, deffo points towards rings or ring land...

When you take number 3 HT lead off is it coverd in oil aswell as in plug hole?

No ht leading dry mate

Try & get the oil out of cylinder 3 somehow by shrige'ing it out somehow & do another compression check... If its down on that cylinder then deffo a ring/ring land issue

Hi mate, didn't you recently rebuild the engine due to a failed ring land? Is it the same cylinder at fault as previous?
From what I understand ring land failiour is usually caused from detonation, could it be you have a fuelling issues and detonation has destroyed the ringlands again straight away? And as others have said you could be getting a false reading from the oil in the cylinder giving a false reading. I don't meen to sound so negative with my suggestions but I know you have been trying to get to the bottom of this issue for some time.

Whatever it is I hope you get to the bottom of it and I'm sorry your R has given you so much trouble, I know what it can be like, I was a victim of ringland failiour a few hundred miles after buying my car lol

It was cylinder 4 before and it would only let out a could of smoke after you let off now it's cylinder 3 mate all pistons were taking out and checked and were all ok I chucked som fuel down the bores to was them out not checked since if the oils still there but I'd imagine it will be I'll try clean it out and compression test it again the thing pisses me off that much it needs scrapped lol

Hi Scotty now just to let u know I had the same issue with my car but it was not an r it was infact a vw vr6 which I had turbo charged and it began to smoke I thought it was the turbo at first then I had the enginge taken apart and the Conrod was shaped like an 's' so it was a re build unfortunately.
I have one question if u drive the car at a very low rev speed I mean on no boost at all over say 10 miles very very gently does the smoke disappear? If so I think it will be a Conrod that's failed and ultimately messed up the way the piston functions but then again I could be wrong just saying that looks exactly how my vr behaved

I would say a ringland imo or ring issue ..... if there is oil sitting on top of the piston it will seal it when doing a compression test i would dry it out ....use like a long syringe to pull as much oil out as possible and do a leak down test will give you more of an indication .... are you getting any blow back through the crank case ?

oil scraper ring or whatever its called, oil still staying on the cylinder walls and being burned off, had similar problem and compression readings were fine, however that might not be your issue just saying compression and ring problem

Is there no chance it could be the valve stem seals? Did you put new seals in the head when it was re-built?

Thats why i said a leakdown test as it will give a better insight into the problem.

I too would think it's more valve related from reading through this thread.
A bent valve is my thoughts.

Nah not a bent valve the timing was out a tooth and I put it back in a tooth before a moved house and never drive it after puttin the timing correct but as far as I'm aware incorrect timing wouldn't cause this?

It never got new valve stem seals either when it got the new pistion fitted ill do a leak down test and see what it says

I wouldn't of thought valve stems would create that much oil in the cylinder tho? As it usualy would only let a smear of oil past the valve itself as the tolerance is to close to let anymore threw, so its only enough to burn off...

Ive heard of a lot of cars run without valvestem seals for different reasons & they just put up with a little smoke out of exhaust

If timing is out it will cause the valves to be bent, maybe some people get away with this, but I know of two gtirs that didn't get away with it!

Are the breathers on the rocker cover capped off at all?
I've only just looked at the vid and that's a lot of smoke!

T piece on the rocker cover is open with a mini filter plus if the valve was bent sure it would run like a bag of shit still drives boost fine etc just the smoke

Suppose you wouldnt get good compression readings if a valve was bent. Would still be checkin it tho especially since the timing was out.

It was only out one tooth I was turned over by hand before it was turned over with the key so if it was goin to hit and bend a valve ud feel it by turning it with your hand
