Guest Tim78zt Posted March 7, 2003 Share Posted March 7, 2003 A search for this info turned up goose eggs in this forum's archive's, so if you have a turbo engine factory manual please look up the the #'s for adjusting valve clearance for me. I have the 78 manual but need to confirm if the clearances are the same before I trust #'s for a different head. Thanks!! My replacement motor is running well on 7psi for the time being and All Z Car has begun the teardown process on my broken motor. They pulled the head and #1 piston yesterday. We found pretty much what we expected. Wrong pistons (I bought flat-tops...dished pistons were installed) without any sign of ceramic coating on initial inspection. Broken ringland but no sign of cylinder scuffing. That's the good news. Still need to measure bore to see if I got what I paid for there. Pics to follow.

Guest Tim78zt Posted March 7, 2003 Share Posted March 7, 2003 Thank you for the fast reply, Tim! Much appreciated!! I think the search engine is down. I tried looking for a NGK heat range recommendation and came up empty there too. Tim78zt Quote Link to comment Share on other sites More sharing options...
