Hi,
not sure what 'valve head right at the gasket" means.......
but if you found an oil and water mix............
what I've found is that *all* waterboxer engines that have been running a
number of years.......
need to have their heads removed............and uually a basic valve job in
a machine shop, and new
head gasksets.
In bringing many vanagons back to health, unless I can tell the engine is
pretty fresh, the heads need to come off, at the
minimum. Almost like it was part of a regular tune up ........not quite
that , but almost.
Most of the time..............that outer water retention rubber gasket is
corroded, the aluminum surface of the head where it mates with that rubber
gasket is corrodded, and the tiny green o-rings at the top of the barrels
are very hard and stuck in their grooves- like they stopped doing much
sealing a long time ago. If it's a typical tired waterboxer
engine..........I'd say that head, or both, defenitely need to come off.
