You need to take those heads to a machine shop that rebuilds the
heads of engines. Have them check the heads and rebuild them as needed. They
will check for internal cracking, check and replace the valves, valve guides
and valve seats if they are needed. Have them give you an estimate of the
cost beforehand as if the heads are in really bad shape it would bet better to
buy new AMC heads. Don't forget to inspect the ends of the valve adjusters.
If they are worn or pitted badly they must be resurfaced or replaced.
>>>>>>>I'm working on a 1985 Vanagon with a stock 1.9L gas engine. It was
"remanufactured" by VW about 50K miles ago. It began leaking a bit of
coolant over the last couple of years and a few months ago it began leaving
4 to 5" puddles on the shop floor. I decided to remove the engine to R&R the
heads because I was going to replace the exhaust system as well and I know
it's much easier to access the head and bolts for both projects.
I've got the engine on my bench, the heads removed and cleaned but I'm
stumped regarding the condition of a couple of the intake valve tops. There
are small areas of missing metal that looks like a coating of some sort. One
valve (#4) has just a few 1/8" pieces missing and the other (#1) has perhaps
20% of the coating missing in various sizes but none larger than 1/8". The
missing metal is on the outer, flat part of the valve.
Can anyone shed some light on this condition? Is it fatal? I'd like to get
at least another 50K out of this engine without pulling the heads
again!<<<<<<<<<<<
