[s-cars] Lifter noise

[Tom Mullane]

Craig,

BTDT with my 87 VW Quantum Syncro.  A half a quart of Dextron would quiet
the engine right down once the "oil change reminder" kicked in.  Of course,
by the time I started dumping ATF into the motor, the car was so old and
beaten up that I wasn't really concerned with any side effects.

Mike, I have yet to experience the lifter noise issue with my 70K mile S4,
but I sure did with the 86 4000Q I owned for twelve years.

Generally, this would make itself evident if I had not changed the oil for
~4K miles. An AUDIble oil change reminder if you will. I believe the noise
stops with new oil because the old oil's detergent package becomes less
effective with use.

As an engineer, I am particularly suspicious of "snake oil" products, but
there is one that I buy and recommend, and that is Rislone. On my 4000, if I
did not feel like changing the oil, a quart of this would stop the noise in
20 miles, and would be good for 2K more. Friends have had similar results on
their Audis. My iron clad proof of it's effectiveness was with the Mazda MPV
we owned for eleven years. These V6's have a valve lifter noise problem that
was the subject of recalls, and was severe. Rislone silenced these as well.

FWIW & YMMV
