Ok so I have spent about 2 hours searching the forum for my kinda problem and I canít seem to find it so Iíll try to describe it.
I have a 1995 ETC with 97XXX miles. Just replaced the radiator and not a week later Iím getting a disturbing sound. It is a knocking coming from under the drivers side of the car right behind the front tire. Now this sound is only really apparent AFTER the car has warmed up. I can hear it at idol and when the RPM is up to about 2000-2800, above that the engine sound is too loud. The sound speeds up with the engine. On the road I can hear it at 65mph, although faint. I disabled one cylinder at a time and got no change in the sound. I have clean exhaust tips and do a WOT once a week so I donít think its carbon build-up. Iím on top of maintenance and do my own work since I bought the car (around 75xxx) and only use Mobil 1 10w30 with 91 octane gas. Part of me wants to say itís something with the tranny but I know nothing about them.
