205 Gti engine problem
Hi all,
I'm posting this on behalf of my brother,He has developed a problem with his 1900 gti.Anyway here is what he has posted else where,I thought I
would try it on here.
Anyway,I done my first track day and the car was going superb but with 15 mins left of a 2 hour session a problem developed,I'll describe to the
best of my knowledge.
I was flat out in 4th gear going up the straight,I braked and selected third before going into a corner,I checked the rear view mirror and there was
nothing but blue smoke.I got back to the pits and lifted the bonnet,There was oil all over the top of engine which had obviously blown from the
breather,I also noticed the destinct lack of power aswell when this happened !!
The car still starts(not quite as easy as before) There is no rattles,The engine still sounds fine ! Am I correct in thinking that this could be a
piston ring problem ?
If anyone has any input it would be much appreciated,As it stands just now,I'm thinking of pulling the engine out and rebuilding the bottom
end.
Cheers guys
Mike

Ah, we have detail now  sounds like a ring or valve stem oil seal maybe, need a compression test really.

Thanks for the replys,The car has a baffled sump,I had to fit it !!!
I will get a compression tester on Monday and will check the cylinders,My automatic reaction was also rings but I know nothing about Peugeots !!
Cheers Guys

They have a bottle brush arrangement in the breather pipes. Take it out, clean it and replace it.
If that doesn't work - rebore, rings.
If you can keep you head, whilst all others around you are losing theirs, you are not fully aware of the situation

Unlikely to be valve stem oil seals as the engine was covered with oil . Typical valve stem seals symptoms is smoking after a period of idling .

If the valve stem seals have never been done they will need doing on a Pug. However that's unlikely to be your problem here - as above stem
seals result in smoke on start up and after idling.
I'd start be removing and thoroughly cleaning all the engine breather and oil filler pipes followed by a an oil and filter change. Use a
genuine Pug oil filter, they're not expensive and they have the correct pressure relief valve built in.
As touched on above the oil filler cap is an integral part of the oil breather system. These tend to get clagged up over time with oil deposits which
chokes the breather system. At worst it will be full of white gooey mess. From new it's fitted with a ball of wire mesh designed to seperate
oil from oil vapour before it's recirculated into the inlet tracts. The best thing to do is simply replace the filler cap with a genuine new
Pug one.
While you're cleaining the breather system also dismantle the air inlet hose from the throttle body and give the body/butterfly a really good
clean out with carb cleaner including the little idle bypass air passage that runs through the casting over the top of the butterfly. Lightly oil the
throttle linkage afterwards as the carb cleaner tends to get verywhere and remove any existing lubrication.
The drop in engine power was most likely due to the engine sucking in a looad of oil which will have fouled the plugs and then burnt off giving the
smoke output you noticed. As a matter of course I'd remove and replace the plugs to ensure you start afresh.
Good luck

Assuming the sump wasn't over filled either a b choked breather or knackered piston rings.
If it is an oil control ring it won't normally show up in a compression test or a even a proper cylinder leak down test..

Thanks for all the input,much appreciated.
I've been for a look at the car today,I'm of the opinion that it's requiring rings,It does tick over but not as good as before,The
oil pressure when cold used to be 80PSI,now when ticking over its down to 50PSI(until revved it goes back up to 80)
I would have thought if the breather was choked you wouldn't be able too see it breath at the oil cap,Even when I removed the dipstick today
when the car was running there appeared to be a lot of back pressure there also.I will check all breathers this afternoon before pulling the engine
out tomorrow.
Thanks again
