Mn_Z_Man Posted May 7, 2009 Share Posted May 7, 2009 Long story short , I bent a valve during a timing chain replace. Oh well, good excuse for a valve job. Small nick in the piston, otherwise no apparent damage. Intake valves and guides seem OK, exhaust needs some work. I was planning on new guides for the exhaust, and valve and seat grinding for all, and of course new seals. What I'm wondering is will a valve job require new lash pads to keep the wipe pattern centered on the rocker? I don't know how much they typically take off and if it is enough to matter. I have no confidence that the shop will be able to tell me, as one guy told me the lash pads aren't there for shimming, that the lash adjustment takes care of that, which is wrong. Most of the pads seem to measure the same at 0.12". Have no idea how much seat is left, but they don't look too bad If it is likely to change the geometry, would I be better off grinding the valve tips to keep the same height, or experimenting with new lash pads, (which sounds lie a PITA)? Engine had 120K, great compression, etc. Cam and rockers look good. thanks a million Eric Quote Link to comment Share on other sites More sharing options...
WizardBlack Posted May 7, 2009 Share Posted May 7, 2009 It's easy enough to check. I'd do it even simply because the engine has a lot of miles on it. If you do that, may as well put a cam (or regrind) in it. You would already be paying for the expensive part. Quote Link to comment Share on other sites More sharing options...
