November 9, 20169 yr Hi everyone, A few weeks ago I noticed a noise in my engine. Oil level at the time was normal and dark. I then changed the oil and filter with my normal 10w40. Still has a very audible noise coming from the driver cylinder head. I replaced the distributor assuming a bad bearing because most, if not all of the noise was heard there through my stethoscope. Not the case, so I re-installed the original distributor and am back to square one. Please view my video and if you want, you can jump to minute 3:15. The audio did not turn out that well for the warm up, but sounds better at minute 3:15. Thank you for your help and any input would be helpful. Will
November 9, 20169 yr Hard to tell with your audio and the exhaust leak noise, but I do hear what sounds like a rod knock to me. Definitely not a tick noise.
November 11, 20169 yr Author Alright I have an exciting update!! Yesterday I removed the driver side timing cover and found that the driver side timing belt was really loose...about 1-inch of travel up and down. A lot of slack. So today I removed the passenger timing cover and the passenger timing belt had better tension but still a little bit of slack. So now for the exciting part! I reset the tension on both timing belts and fired it up. No more noise and now this little motor purrs better than before! Definitely a relief and piece of mind. Maybe the slack in the driver timing belt was causing free play somewhere inline of the distibutor during idle...don't know for sure. All I know is that my belts are tensioned properly and the noise is gone! There is about 30k on these belts so I think they stretched a bit. Anyways I hope this may help anyone out there with an engine noise, and that I recommend them to check the timing belt tension FIRST! Thank you!
November 11, 20169 yr Maybe the water pump going out - that would also be a rotational bearing type noise. If you can safely listen to the pump with your stethoscope, it would be worth ruling it out. --Never mind, you posted your update while I was watching the video .. Glad you found it.
