lifter noise

["Dorothy Raymond" <d.raymond@cablelabs.com>]

Hi!  My husband and I are new to the quattro.net, but long-time owners.  We
have two, a l987 4000CS Quattro and a l991 200 Turbo Quattro (just like Shirley
Temple Black is reported to have ;-) but without Boge shocks)

Our 4000, at 150,000 plus miles,  is developing a rather severe lifter noise
problem.  Over the last year, we've tried thick oil, thin oil, synthetic oil,
and it still makes the same noise.  Engine oil pressure is ok, and the
compression is still ok.  It doesn't burn a lot of oil, either.  It sounds like
it's coming from one or two cylinders, not all five.

Obviously, we don't want to start tearing apart the engine--or even removing
the head--if we don't have to.  But, since the noise is getting to be too much
to ignore, that may be our only hope.

Before we do, anybody out there with the same problem that you've found a cure
for?

Thanks in advance!!
