What is the best way to search for an exhaust leak on the Passenger side header. Is there any particular place on the header that is prone to cracking.

Thanks in Advance

Cheap trick....

The best way to locate any exhaust leak is to use a piece of hose (like 3/8 fuel line). With engine running, symply hold one end of hose to your ear and move the other end of the hose around the exhaust flanges, pipes, etc...cheap yet very effective. :cool:
 
The real check would be to take it off and hold it up to sunlight. If you think it's cracked, then in all likelihood it is! They are notorious for cracking the driver's side, but certainly do also crack the passenger side too. One simple thing you could also try, just to eliminate doubt, is to check/tighten the two bolts that connect the crossover pipe to the header flange. I've had them loosen up over time, and create a leak at the flange. If that doesn't work, then try the "hose stethoscope". After that, prepare to take the thing off and get it welded, as I suspect you'll need to do.

It's really a shame that GM did not have the foresight to have the exhaust manifolds for TR's made from stainless steel originally, as they did for the TTA's in 1989. This would eliminate this reoccuring problem...
 
One other unrelated note of curiousity, per your sig line. You show your car to be 3950 lbs. Why is it so heavy? Are you carrying a truckload of cement???:confused:

LOL
No ... its not cement just some audio equipment to a tune of about 250 lbs.
The car was a "showroom car" for a high end stereo shop in Chicago. When the business went "belly up" 3 years ago I bought the car with 9900 miles on it. So now I can drive around and play tunes not only for my friends in the car...but for my friends in Europe as well :cool:

The headers on my '87 are stainless steel. Came that way from the factory, and as far as I know, all the '86 and '87 cars had the same headers. They cracked, anyway. But I got a "trade-in" for the drivers side from Jack Cotton, and it's held up for several years. It's not a pretty, shiny, stainless, but it is stainless, of the "high temp" variety, rather than the 300 series.
 
Another way to check for leaks but should be done outdoors, is to allow some tranny fluid (2-4 oz) to be sucked into the running engine.
You can use the vapor recovery line before the check valve to inject/suck in the fluid.

If you have any leaks under the hood or on the exhaust system you will find them when the smoke starts coming out.

This will work.
