i know the ims bearing issue has been talked about till death, but id appreciate some feedback.
So ive got a 1999 2.5 with 72000 miles on the clock and its still has the original ims bearing. The other day i started it up and decided to try and get underneath the car as much as possible to see if i could hear any noises since some people report some kind of strange noises before bearing failure. After my mind managed to isolate the exhaust noise i was hearing a noise, which sounded like......TAC TAC TAC TAC coming from the engine. It variated according to revs. i could hear absolutely nothing when i wasnt underneath the car, except the injectors ticking. The noise i heard under the car as more like a low pitched clank. Is it normal for boxer engines to make this noise, or should i be concerned?
