Hey micah or anyone,
what would the chain "rattling" sound be? I have a low rattling sound(diesel-like) at low rpm's that I thought was just the muffler touching the bellhousing. It goes away when I give it the slightest bit of gas. Is that possible the timing chain? Lots of power though.
My 1989 toyota pickup timing chain went bad at about 190,000 and cut a hole through a part of the engine, leaking oil- but it was a higher almost pinging sound from the loose link hitting one spot over and over.
