After you boot my car it smokes when you put your foot back down
whats a common cause for this? the turbo has no play it feels mint
but could the seal in it be knackered , breather issue ? valve stem oil seals?

 

What colour smoke mate ?

 

sounds like turbo mate as my old escort done that.well that was blue smoke anyway.

 

u mean it puffs out smoke when you give it large back off then floor it again?if so perfecty normal

 

agreed

 

Breathing or mapping, either way I wouldn't worry about it unless its smoking constantly on full load

 

nothing wrong with smoke from a cossie, if it dont smoke you aint got oil in it

 

ive had plenty of cossies & this is exessive after booting it when you put the foot down again it a fair bit of blue smoke i would suspect turbo but its nice n tight no play in the shaft

 

Piston rings or turbo seals I was told when I had a similar problem.

 

blue smoke is oil Carlo.

is it using lots of oil or is it ok.

 

its using a bit dave but all cossies do as you know, can the turbo seals go but the shaft has no play?

 

yes mate, they all do.

not too sure on that question Carlo.

could be a number of things mentioned above Carlo,hard to find what if all is ok with everything.

can you put up with it or is there loads of smoke..

 

its quite bad dave & annoying as well .

what i was saying is that if the turbo has no play is it possible for the seal to fail

 

can only hazard a guess

try overrunning down a long hill, and give it a boot at the bottom, if it puffs out blue its likely to be worn guides or stem seals

if it really bothers you and you're using shit loads of oil, then i would start with the cheapest, like a rebuild on the turbo, circa Ł200 (assuming only seals and a balance)

then i would start looking at worn oil rings, but these dont show on a comp test, so if you're gonna pull it apart you might as well give it a refresh

yup, afraid so!

 

Fuck , i prob wouldnt rebuild my engine i would maybe just buy a standard 4x4 engine have it rebuilt & stick it in cant be bothered with the car being off the road for any length of time

 

I'd check the inlet plenum elbow for signs of oil if there is some in there take the compresor to cooler pipe off and check there if oil is coming out of compressor if there is then its turbo

A sticky oil residue is normal but oil drips is a problem as it collects in cooler and on boost chucks it into manifold which then when u let off creates vaccum and sucked in by engine and burn't

the boos pipes are new but there was no oil in them

 

sorry Carlo, i understod the question,just not sure on the answer lol.

 

+1

 

+1

 

as said above ive had loads of cossies & none of them have been this bad so its not normal

 

andy not got a turbo mate you can stick on just to try before you go and spend any cash.

 

I know its a different application... but my DC2 Integra TypeR was doing similar and I replaced the valve stem seals which cured the problem.

As well as giving it large into VTEC and then allowing it to come down on over-run and putting foot back down, I found that sitting on the spot revving to the high to mid rpm-range, letting it run down a couple of 1000 rpm and blipping the throttle was producing a bit of blue smoke from the exhaust.

ah sorry missed that! if its after overrun when you bring back on the power its normally valve guides/seals as most bottom ends/turbos ive seen or had go on me normally smoke whilst on power....

 

If it was stem seals & valve guides im not bothered i would buy a head & have it reconed , it certanly seems like its only doing it on vaccum but when its cold first thing in the morning it dosent smoke a bit

 

mine does the same carlo :-( and it pisses me off too

id like to know wot checks i can do before spending big cash

 

When the oil is nice and thick then.
