Hey guys! I just put in my newly rebuilt, factory IP, fixed the massive oil leak I had with new valve cover gaskets, did a coolant flush and new coolant, and put new oil in and now the rig runs great, AND DOESN’T LEAK!
But, now it appears I have a set of new problems...
Everything runs great, IP is timed more or less (I think its a degree or two too retarded; alright power, no white/blue smoke, but runs pretty quiet),and NO LEAKS... but after running it for 30 miles, an ambient humming noise coming from around the CDR valve/bell housing area has popped up at idle (1500-2000rpms). It’s loudest when I’m either under the truck by the tranny or with my head reached over the intake. Nothing seems to change it; clutch in or out, giving it gas, nothing... thinking maybe something is vibrating on the firewall? Doesn’t sound like the IP. Honestly have no idea on this one... its freakin annoying though...
You guys have any ideas?
