1988 Mazda 626.160,000 miles. Recently I've noticed an intermittant " dogging" sound from the motor while driving. Not any really noticable loss of power
but I can hear it in the engine. No service lights are coming on at all. When I opened the hood to check the oil, which was fine, I hear some pretty bad lifter noise that wasn't there just a short time ago. Could this problem be arising from a clogged screen or filter somewhere? If so, is there any way to " help"
the problem short of a major repair. If not the problem any other ideas on what it could be? Any advice will be greatly appreciated. Thank you very much.
