smokey exhaust

[donk v8]

my exhaust smokes a lot on my peugeot 205 1ltr petrol 1990 since i changed the head with a used one from a breakers, the cam belt went so swaped the head.
cud it be the valve stem seals or a piston ring?
it didnt smoke before.

did you damage the old head or any of the valves or did it warp

[phizzy]

take it to your local pub - it daren't smoke there

[phizzy]

seriously tho' it was same on mine few years back turned that was valve seals / guides

[mrrossi]

if you only warped the head by 1mm check by using steel ruler or known flat edge it can be skimmed usually �20-50 if there is no warping of the head or damage use the old head

If its the valve stem seals it will smoke when you start it up (after its been sitting for a while)

If its a general smokiness (but without the smoke on start up) it is more likely that you have'nt had the head skimmed and the valves re-ground.

It may run like it for ages or not..
