I have no experience with the water cooled engines but I have a lot of
experience with air cooled. And when one of those made a very hard knock
you'd better grab onto your wallet because it's about to lose a lot of
weight. Maybe not today, maybe not next week, but very soon.

Did you try to call & I did not answer? I apologize but I never answer
numbers I don't recognize because I'm tired of sales people trying to sell
me life insurance, health insurance, Obama insurance, merchant services,
very expensive money and the latest, greatest "guaranteed to make millions"
investment.

Subject: Re: Mann Oil Filter and lifters Was:Engine Starting Problem

Yep.  I blew out a filter on startup at about 17 degrees with 20w-50 on my
'84 with a fresh rebuild in it (heavy duty pump too). This was shortly after
I blew up a used 2.1. What a mess, I think it pumped out the whole crankcase
in the five seconds before I noticed the oil light and gauge at zero. It
rarely gets that cold around here, but I now run Mobil 1 15w-50.

If you want to really know what's going on with your engine and bearings,
install an oil pressure guage.  Ignorance is not bliss with waterboxers,
especially with the 2.1s!  VW knew this, and that's why they installed two
pressure sensing systems.  In my experience, when those rod bearings go they
go fast and without warning other than with low oil pressure or a very hard
knock you can easily tell from tappet noise (In my case in about 3000
miles). If you hear that knock, stop driving if you want to have a core to
rebuild!  I didn't and it cost me.

Even in a worn out Waterboxer, 20w-50 should not be used in cold weather.
Synthetics give a bit more leeway but as you near the teens many destructive
things can happen with too heavy an oil.  For the winter I even go down to
the 0w-40 European formulae for my daily drivers. If I have to drive Fun Bus
to work on a cold day with the Mobil 1 15w-50 I let it warm up a bit and
drive extremely gently until I see the oil pressure drop a bit on the gauge.
