Exhaust Squeal

[jb92563]

Did you mention whether it was proportional to engine speed?

Could it be that the header or header gasket is not torqued down properly and leaking a bit.

From too many years of experience, always consider the most unlikely to be perfectly possible, especially when you've run out of logical ideas.


In light of that you might also want to check for a covertly planted critter whistler or a racing pig taking up residence near by.

Perhaps a noisy belt or accessories being run by it are the problem.

The squeal persists at idle (especially warm up), and is more pronounced with "blips" of the throttle and falling RPM's. As I mentioned, the squeal can be isolated by putting pressure on the exhaust in various locations. So far, the hanger, clamps and strapping have all been checked for looseness, and tightened if needed.
