W124 602 valve & Seat Machining ?
Hello,
602 valve job in question... Are the valves & seats hardened with any method that requires a specialized machining process beyond the normal scope of a standard well equipped machine shop. In other words will the sealing surfaces be compromised in strength by being machined ( the reason I ask is SAAB uses a stellite hardening process on the exhaust valves which once cut through turns the valve to junk ) thanks |

Nothing all that special on those engines regarding the valves. Certainly the seats are hardened as all are for quite a time now.
For some reason the last cylinders valve seats have been known to regress into the head further than the others with high milage. Just a straightforward repair though if needed. I am only responding because someone more knowlegeable has not yet. |
