just noticed a strange noise this weekend, coming from engine. up with the hood, and i cant place where its coming from. the engine has been very quiet for as long as i have owned this car, so i'm wondering. it does follow engine speed, but its not regular? i have to say it sounds like its coming from the exact middle of the engine, like something is loose. having said all of that, i have owned the car since late 2000, and all belt maintenance kept up to date. i have always checked the rollers, and they were ok at last tension, however, the more i think about it, it could be the bearings/water pump. any thoughts?
still the same rollers since 2000, and water pump has about 30000 miles on it.
guess its back up onto the ramps tomorrow for further investigation.
