I am concern about vibration from my 3gm30f. Should I have the engine mounts replaced, they look like the 20 yr old originals? How long can you depend on those rubbers to last. The mounts are not broken. Have you replaced your mounts to improve vibration ? The mechanic left a cryptic note on his handwritten copy that just said vibration. Perhaps that was caused with problems with the old exhaust valve that restricterd rpm to 2200 but I am just guessing.
There is one lower rpm the engine really shakes, but do all engines have that sour spot as well as a sweet spot for rpm ?
Donalex I am thinking would say replace...
Replace ?? or don't worry so much...
Thanks for your help[again]
