I have a water boxer engine with an oil cover seal leak that I would
like to fix.  The Bentley mannual is worthless about this issue--tells
hardly anything about working with the oil pump and mentions nothing
about seals.  Looks to me as if the full oil pressure is working against
the cover. But I really can't tell if the leak is from the surface where
the cover meets the oil pump housing (which seems most probably), or
whether there is a potential leak from what looks like a seal behind the
oil pump housing.  The surfaces look smooth, and the seals look good.
Any sealant you would suggest I use to get a tighter surface?  Any BTDT
on fixing this common leak?
        Help would be appreciated.  I am on the digest, so any direct email
would get to me sooner.  Thanks,

Joel Skousen
