hi im new to this site so would like to say hi. iv just recently decoded to sell the old fiesat rs turbo and buy the mrs a bmw and me an old 1986 sj410 i got the old tank cheap so im not worried about having bought a lemon lol. the body work is great and we have sum test on the old girl so its great just wot i wanted when we get some snow. the problem i have is the bugger smokes like hell! and stinks like oil

but its grey smoke not blue? im no mechanic but no my bits and bobs and first thought is stem seals but just not sure as maybe head gasket???? iv run some stop smoke through her but that doesnt seem to have made a diffrence it does settle a little when warm but soom as you touch the gas fills the street lol.... i dont want it to be perfect as its only my winter tank but any help or cheap fixes would be great thanks. joe rotherham

Hi and

The most likely cause is probably the valve stem seals.

Seems to happen to most of them at some point

Start with the basics mate. Compression test. If you think it's stem seals then easy job get head off, rebuild and back on with new head gasket

If the smoke is there pretty much all the time then more likely to be worn piston rings. I suppose it's possible that it would burn oil with a blown head gasket but more likely that you would notice other problems as a result of gasket failure.

Yeah I didnt mean start there but from experience of these engines it always seems to end up being the case.

to scuk matey good choice on the vehicle, once you sort the

issue the little 970s are rev happy little monsters.

If it smokes constantly chances are that it could be piston rings, to check those do a compression test and write down the readings, then pour a small amount of oil into the each cylinder and do another compression test, if the values are higher then its your piston rings if not its more than likely just the valve stem oil seals.

The pcv valves rarely play up on these but you should be able to hear it rattling if it is working. I doubt its the cause of all the smoke but pop it out and give it a clean by shacking it about in a tub of petrol/carb cleaner if you want.
