Title: Valve Removal Question
Post by: e30nut on June 24, 2008, 07:23:19 AM

Gruppe:

Got a fancy new valve spring compressor, and I'm about to tear into a head rebuild/swap on my broke 91 318is. Frankenstein job, one cracked head w/good cams/valves and one recently rebuilt head that valves crashed when timing chain broke last summer.

Question: any trick to removing valve retainers that I should know about? I can certainly practice on the crashed head, but I want to be real careful not to mar the seats/guides, and conversely the on cracked head, not to damage the stems. Anyone BTDT?

Cheers!

it should be pretty straight forward. just make sure you have the tool centered on the retainer so it doesnt slip off and shoot the spring.
