... thanks for posting the information on the PSP Linus.  I
was going to do the same.  I wanted to add some further info,
that I did replace the return valve on my '88 5kTQ and saw
no change to the lifter noise problem.  I noticed that I got 
a sale flyer from one of the non-dealer parts suppliers, and
they listed the 034 109 309 AD part number (PAP?)
