hi there i need some help on trying to get my car from stop smoking. ive changed the valve stem oil seals and head gasket but it still ploomes with smoke on start up but clears wen its warm. any ideas what this could be?
cheers.

 

Mine has just start to smoke when started cold and clears within a few seconds going to change stem seals any advice in doing them.

Cheers joe

 

it could be all sorts of things .... even a bad fueling set up but check the turbo and boost pipes for oil and it could be signs of the seals hardening when cold cause oil to seap through

 

if the staem seals where gone it would smoke when you let off the throttle .... they are easy to change mate just get a set of seals and a rocker cover gasket.

tools make sure you have a good pen magnet to get the collets out to remove the valve springs out..

just turn the engine over untill the one you are changing is slack and push down hard with a big ring spaner on the ring end or get a valve spring press and use the magnet to remove the collets take of the spring and fit new stem seals... then just put it back how it was. then there is no need to remove head.....

hope this helps

 

sounds like over fuelling on startup, mines a pig when cold for this, but never have time to sort it out.
if that's not the case then could be turbo seals on the way out.

 

If its white/grey smoke then i would of said the turbo is naff

 

as above,had loads of trouble in the past,with the same thing,turbo seals could be gone

 

the only thing i will say is the turbo can leak from the turbine seal thought
blowby and heavy breathing engine

the turbine seal is a small piston ring and will be the first seal to blow when
the is a lot of crank pressure also bigger turbo exhaust housing will help
to leak as there is less back pressure in the exhaust

just something to think about

 

i had the same on mine and i found that it was running rich my m8 put it on c02 meter and sorted it out then no oil burn on start up.....?????god no's what it did?

 

oh rite thats wired. how much did it smoke on start up tho?? cause if thats wat it could be il try that .

 

not realy bad but i could see bit as i drove down the road.for 5 minets then no smoke at all

 

oh rite well mine smokes really bad then after 5 minutes it clears so aint got a clue wat it is

 

the rs turbo im looking at does something similar but he said it needs setting up anyway and it could well be the fueling after reading a post or 2 above.
