waiting for valve job... 700 1990

posted by  someone claiming to be mark whittier on  Wed May 30 16:31 CST 2001 [RELATED]

I am patiently waiting for my cylinder head to come back from the machine shop after having ten bent valves due to an oil pump pulley bolt breaking. This is the 16 valve engine. I have a question for you all. Like some big block or other American made engines, is it a concern to do a valve job and not replace rings or other lower end parts due to compression increase resulting from top work? The engine has 149K and ran very well prior to "the catastrophe". Another question.....Any tips on how to accurately get the additional 60 degrees rotation on the oil pump drive pulley bolt after the required 15 FT/LB? I know this is a critical torque and I want to do it right.

By the way....there was a reader who asked, "how much carbon did you find in the cylinders when you got the head off"? I don't remember your name or address, so hopefully you will get this message. Not much carbon at all. Cylinders in great shape, still shows crosshatch.
