I have a 2008 Pontiac Vibe with about 213,000 miles. It is an automatic. Have had regular service done. It has started to make a noise in the engine. I thought it was the tappets. I drained some oil and added rislone. It did not do much. When I had the oil changed, I asked the mechanic about the noise. He said he scoped the noise and said it was not the tappets. He could not find where the noise was coming from. He said if it got worse, let them know. Well I thought it could be either the water pump or alternator. The lights or radio is not being affected. The water pump pulley is running fine. No wobbling. What do you think? Thanks
Is the noise mostly on cold start-up and goes away after a few seconds? If so, that's the VVTI - I believe there's a Technical Service Bulletin on that.
the rattling noise goes on when you start the engine. It does not go off
OK. Not the VVTI. If you're wondering if it is the water pump or alternator, you could take off the serpentine belt that runs them, then feel how the bearings are on the accessories and tensioner. If you can hear rattling inside the passenger compartment, one would have to be pretty bad. I think Scotty demos this in one of his videos
this isn;t a fix
back in the days of hubcaps, us juvenile delinquents would put marbles in a guys hub caps when he wasn't around. drove him nuts! :silly: 😆 😡
