Engine + Driveline / Help with rough noise!

« on: August 15, 2017, 01:58:33 PM »

I have reconditioned this E30 pretty well and drove it 3000 miles these last 2 weeks, took a road trip with it. Anyway, It is still running strong but sounds different from before the trip. It sounds rough, but idles smoothly, no oil light, power seems the same. I did find that when I hold down the oil cap with all my weight or valve cover (when its not too hot). The noise goes away! & It sounds just like before minus the rough noise.. I though it was rod bearings, or exhaust hitting the frame somehow, but I'm just dumb founded, will a vacuum leak some where cause this noise ?
 
 I know my VC gasket leaks into my 1st & 2nd Cly Spark plug wells & I do see oil slightly leaks from my oil filler cap. That shows at least my oil pressure must be good.. but as for the noise ?
 
 Any help is appreciated Thank You

Check your fuel supply first, That has always been my M42s issue. It started to eat fuel pumps up FAST. Turned out to be loads of rust in my gas tank causing it, so check either of those.
