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.
