I tried something day before yesterday in hopes in fixing the grinding noise
coming from my engine...In a last ditch effort, I added a product called
CD-2 oil detergent.  In added it to my oil the night before.  The next
morning, the noise was still there, so I drove the piss out of it (mainly
because I was running late for work) and at lunch when I went to start the
car my battery was dead (because I left the lights on and my battery was on
its way out anyway).  I jumped the van, and I suddenly noticed that there
was no more noise from the motor.  To boot, the motor runs better than it
ever has.  I'm just amazed!!!!  I talked to my mechanic about this and he
told me that he used to recommend C-2 oil detergent to his Vanagon customers
that were having lifter problems.  I don't know what to say other than the
motor runs silent.  It's amazing!!  This product is available at most auto
parts stores.  I had nothing to lose because the motor already has over 100k
miles on it.  I figured that I'll drive it till it quits, but it looks as
though I'm in the clear for now.
