last summer i had some blue clouds puffing out of the exhaust during startup when the car had been sitting for a few days

removed the exhaust manifold and saw that 2 valves were all oily.. removed the head and replaced the seals, but now the car is smoking even worse! it smokes all the time, and the same 2 valves are oily.. did a compression test, and all numbers were fine, 12-11,9-12-11,9-12-12.

the valveseals are installed correctly.

so now what? Valveguides?

Could be valveguides. You are getting oil from somewhere... Its constant now? I would bet on the guides. If it were rings, you wouldnt have the compression you have. If it was leftover oil, it would have burnt off by now....

yes it´s constant now, must have damage a guide somehow when i pulled out the valves, dropped the head off at my local speedshop today.

at what compression would the rings make the smoke? 11.5 ? or lower?

edit: this smoke is on idle, a tiny bit more is coming when reving it up.

I would bet that the damage would be to the valve stem not the guide. Its easy when you are tugging on the valve seals to accidentally scratch one of the valve stems. Unless the damage was to a guide from the start.

The other posibility is that the seals you put on are not securely seated on the guide, or are the wrong/defective seals.

Did you replace just the seals that you saw leaking, or all of them?

Probably wont need new ones again, just depends on the condition of the seals.
