Hello All:
On the morning of an early fall cold snap, I noticed a gas smell on starting up my 1997 960 and got out to check underneath. My oil pan was wet with fuel [i touched it with finger and smelled it]. I continued on to work thinking about it and remembered I had just filled the vehicle up the evening before. I thought, perhaps the leaking fuel was become of a pressure differential on the rapid change in temperature over so short a time. I did not notice the problem again until some weeks ago when I smelled gas again. I went to the message board and found the thread on a leaking cap at the front of the fuel rail. I read the entire exchange with growing interest. Aha! I thought and ran out to the garage, opened the hood, started the vehicle and waited for the tell-tale seepage. Well, there was nothing, nothing near the cap nor anywhere else. The front cap in fact showed no tell-tale signs of leaking. Everything was clean. At the back I noticed a small plastic blue cap which I tightened about an 1/8 of a turn. Hmmm. Could that have caused such leaking? I do not think so. I inspected the rail as much as I could without taking the cowling off. Is there any place else I should look for the leak? The problem seems to occur intermittently with wide changes in the temperature. Beyond that, it seems like voodoo is at work. Thanks for any help.
