I going to have my associate Whitey Bolger get in touch with you, he knows how to handle squealers. He owes me a favor so don't worry about payment! :cool:

I prefer "Rifleman Flemi" if it's ok.

Many have pm'd me suggesting that it may in fact be a loose plug after all. Sound plausible ?

seat.....edge.......resolution I cannot wait!

I checked for a loose spark plug(s), along with a possible loose the 02 sensor, today. Everything was ok - the squeal continues. :(

Get yourself a roll of this and have a party under the Dangermobile.

JD...
Does the noise disappear when the underside is wet (I know you don't take your car out in the rain...) but if you spray water - or better still kerosene - onto the engine mount / suspension / exhaust and see if the squealing reduces or - even - disappeares.
I suspect a dry engine mount or exhaust joint.......

The squeal persists, even when driving in wet conditions. As far as a dry engine mount is concerned, anything is possible, but it seems very unlikely due to the symptoms.

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.:eek:

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.

google "whistling cat converter"; whistling can be a symptom of a clogged cat.

except I reread your initial post - you ruled out your cats?
