Just rebuilding a cyl head at the moment and noticed it has no valve stem oil seals... which might explain the smoke  Now I know sometimes there are seals fitted to every valve and some times they only fit them to the inlet... Do I need 4 or 8 or should I just refit with none as before Also can the Head Gasket be reused as the one on there looks perfect Cheers N. |

I'm not planning on reusing the HG its just that as it looks in such good condition I will probably keep it as a spare.
Regarding the valve stem seals I think I will also go with 8 then.

arn't you ment to use valve stem oil seals in the inlet but not exhaust to lubricate the valve when hot?
when i rebuild mine i think i will only fit seals to the inlet, thats how i found them when i stripped it.
Just a thought.

The head I am rebuilding had none fitted when I stripped and it only smoked a little bit.
I have rebuilt heads before with both 4 & 8 seals fitted. I now have 8 new seals so I think I will just fit them anyway.
Not that smoke is a problem as its emmission exempt... as long as you can see through the smoke that is ;P
