96 Ciera, 3.1. When diassembling the heads, found a bent valve and it's seat sticking out 1/8 -1/4 inch from it's proper position. Can I just carefully tap it down to where it's supposed to be? What holds the seats in position? Appreciative of any advice. - Scotty

i woudnt because you can do more damage to the head like mess up the valve guide or even crack the head...id just buy a new valve..what holds it into place is the valve spring holding the valve shut..and the seat just seals the combustion chamber...00 turbo'd gagt msd 8.5 mm wires,ngk tr-6 plugs,42.5lb inj,65mm tce t.b,ported upper intake,ported lower,ported heads,copper headgaskets,headstuds,160 stat,ls6 valve springs,st3 turbo cam and pushrods,turbo manifolds,custom 'y' pipe,3in open d.p.,dhp powr tuner,garret t3 60-1 .63 turbine,70 compressor,6 pounds of boost...STOCK CAM,STOCK 103XXX BOTTOM END...2.041 60',13.683 @ 100.34

THe valve seat fell out of the head? If that happened, that's what bent your valve. If you tap it back into the head it will just fall out again and bend the new valve. Either get a good used head or take that one to a engine michine shop and have a new seat pressed in.Comment
