Hi to you all, i have one question about engine noise coming from excavator.
I'm in process of purchasing an old 1999 Caterpillar M315 with cat c4.4 engine, and after testing it, everything works great, hydraulic is strong, but engine is having strong very loud whistling (chaining) noise, which is coming from the right side of engine, where alternator is (noise is not coming from alternator). I know that this engine doesn't have timing chain, but the noise is like timing chain is rubbing on something. The owner is saying that this is normal sound of this engine but i doubt that. Should i be worried?
