Our 94 Sundance @ 225,000 on its 2nd engine was beginning to overheat. Like many of my 2.2/2.5L Mopars I felt it was time to replace the head gasket/thermostat and timing belt. The head is off and I have found one of the exhaust vlaves to be burned or chipped with enough metal missing to prevent sealing on the valve seat. I used to have a box of good used I & E valves from 2.2/2.5's I have worked on over the years but regret that I gave them away. Our local supplier had one on their shelf and I;ll consider myself lucky seeing these engines are dwindling with limited supplies available.
I would like to replace this valve with the new one but need advice on preparing the valve seat. I have a lapping tool and compond to prepare the seat surface to imporve sealing and heat transfer.
Your advice on technique would be appreciated.
Thanks in advance
