Re: Rough idle & periodic misfire, any sufggestions?

An update on engine "overhaul" .... necessary because of inlet valve insert coming loose:

The block wasn't so "rebuildable" after all!

Cylinder #4 required an insert because of wall damage caused by wrist pin. I don't like the thought of cylinder inserts, but it may be the best in this case. (The cost keeps stacking up!) Now I'm waiting for four .020" oversized pistons to be shipped in. Next week sometime.

The cylinder head has been picked up from shop. Looks good. $135. They assure me all valve inserts are now "well-cinched" and will be no more problem. (Too bad Uncle Henry couldn't have done this initially.)

BTW, (I forgot to mention this before) as the intake runner was being removed from engine, I noticed that the gaskets on both sides had imperfections (gaps in the moulded seal) that looked as though they've been there forever. I'm sure these things have been leaking ... though not enough to give us CEL's.

Just remember this if you have intake leaks that you cannot find!!!
