More likely the rod bearings, not the rods themselves. It sounds like you have low oil pressure. Oil pressure rises with revs, so that's why the noise goes away at higher speeds. The cause for low pressure can be many things, but if it's been knocking for awhile, you'll pretty much need to rebuild it to fix the damage that's been done so far. A complete rebuild should also repair the cause of the low pressure. Is your oil pressure light on at low speeds? Does it work? It should come on with the key, before you start, and go out after you start. If it doesn't come on at all, the bulb is probably out, or the wiring is bad. Fix that along with the engine. --- Fiesta Cranberry <FiestaCranberry@webtv.net> wrote: > Hi all, > Can anyone tell me at what milage a type 3 engine > generally requires to > be rebuilt?
