Engine Mechanical problem
1996 Subaru Legacy 4 cyl All Wheel Drive Manual 126000 miles
Thanks for your previous response on my 1988 jeep comanche. The fuel problem turned out to be the short link of gas line on the internal fuel pump. It had deteriorated to the point that even though the pump was pumping it was not creating enough fuel pressure. A $1 fix!
I have a 1996 subaru legacy. It has 126K miles. My son drives the car and he complained of some clicking noise. Upon examination I found several of the spark plugs loose. I assume this was because my son, after changing the plugs a few months ago, failed to touque them sufficiently. There was evidence of exaust gasses blowing by (blackened pocelain on plugs). One plug was missing the electrode. After replacing the plug and torquing all to about 20lbs, the engine ran great, no noise at all. After a few days of driving my son complained that there was more noise but worse. He stopped the car and we had it towed home. I checked it and the plugs were fine. I checked the compression thinking perhaps the missing electrode may have gotten stuck in the exaust valve. Compression was over 150 all around. I am now wondering what the noise is as it almost sounds like a connecting rod bearing gone bad. The timing belt was changed at around 70K miles. Could this be it? The engine starts easily and runs smoothly except for the knocking. There has never before been any hint of knocking and there is no indication that oil pressure is low. Any Ideas. What is next?
Thanks so much, Chris
