I recently have noticed that my 2wd cozzy has been smoking, but this is only happening on tickover when its warm and been sat for a while but as soon as u drive it it stops smoking????
Was just wondering if anyone else has had this problem and what is it???
Cheers!!!

I would try an oil change first, Silkolene PRO S is a excellent oil to use.

As tabby says...a oil change is the cheapest first port of call. Off the top of my head and based just on your description tho i'd proberbly go for valve guides if its only smoking as and when you say and not when coming on or going off boost.

how is an oil change going to help this prob?



It must be something valve stem oil seals.

If he's ill maintained his YB and not changed the oil in ages, then it may now be a similer viscosity to that of gnats piss...which would high light any other wear in the engine...or even just tolerences that are at there limits, which if we're honest Fords clearences could have allowed a bus to drive thru when new let alone 20yr later I said valve guides tho based on the fact that its very common wear problem with those symptoms especialy on a YB.

Oil change will help, as said due to viscosity of oil may havebeen drastically lowered especially if MOBIL 1, as it's well known for this, and will not so readily squeeze it's way past the seals.
Without doubt it will if it has any more than about 60,000 have totally shagged guides and seals, maybe also exhaust valves and all the seats too, yb heads lead a very hard life.

Its a rebuilt engine not so long ago and new genuine ford stem seals were fitted!!! Using valvoline 10 40 semi???

10/40 is TOO thin, you want a 50 weight at least.

Im going for the turbo, it doesnt need to be full boost to see if its worn.


Mine started doing the same a few weeks ago and it turned out my seals were worn on the turbo, aswell as my bearings and my shaft


Full rebuild and no smoke

same here. also sometimes a bad map can cause smoking problems. usually too much fuel

Thanks for the comments ppl n will try some more oil but if that doesnt work then looks like turbo build or t34!!!
Cheers!!

i would have to say stem seals an valve guides. you would know if the
seals went in the turbo mine caused a smoke screen on the motoway
when they finally let go lol. anthor give away if its stem seals an guides
is if its been sitting over night and ya start it the next morning and it blows
blue smoke, as the oil slowly drips down past the stems an guides and sits
in the cylinder. i would find it hard to be the turbo as you say when you drive it the smoke clears, if your turbo was fooked you would have smoke
all over the show when driving.

kirky

well the stem seals were replaced in the rebuild with ford 1s, and as for starting it up in the morning i get no smoke at all!!! Like i say its only when ur ticking over for few mins when its warm and oil temp is up to 80 deg c!!!
