Glen,
Sounds like a lifter to me - I would be very careful using a motor flush
product, especially on an engine with that many miles on it. Pull off a
valve cover and check for sludge buildup - if it looks relatively clean,
then I would try Rislone (my Dad's old standby when he would get a lifter
tap on his old T-Bird) or McKay's "Lifter Free". If you see a lot of sludge
buildup under the valve cover, then it would be very risky to try a flush,
you might dislodge enough sludge that it will plug a critical oil passage
and grenade the engine.
Cheers,
Paul Kile

Hi,
My SD1 started making a noise yesterday. I'm guessing it is a
malfunctioning lifter. It is a mostly regular noise, although it does fade
away from time to time. Sounds like it is coming from under the intake
manifold. It's a fairly solid sounding tapping noise.
Sound like a lifter?
Wynn's Engine Tune and Rislone have been mentioned recently as useful snake
oil products.
If it is a lifter, is it likely that there is just a bit of crud in the
lifter that a motor flush or something might dislodge?
My best guess is that this engine has around 140K miles on it.
Glen
