lleaking TTI's

ive got an exhaust leak on the drivers side of my small block 70 duster. its not coming from the head or collector flanges, near as i can tell. that leaves the slip fit tube. car has full TTI headers and exhaust, ceramic coated on the headers.

has anyone had a leak here? if so, how did you fix it?

Get yourself a rubber hose about 1/4" ID by 3' long or so. Stick one up to your ear and move the other end around by the suppected leak. You will find it that way.

Was the tune up ever "off" with the headers bolted up?

Get up early on a chilly morning and fire it up. Look around quickly while the engine is still cold, you should be able to see the condensation vapor leaking out where ever the leak is.

the headers were installed when i built the motor and car. the tune was off for the first couple of engine firings.

this is the first ive heard of using a hose. can you elaborate some?

and here in NC, were officially out of chilly mornings fpr the next 6 months or so.

Try pouring oil or Marvel Mystery Oil in the carb to make smoke and maybe you can find it that way.

snag a used stethoscope from ebay. remove the chest piece from the end, and put a small piece of metal tube on it. (to keep from melting the rubber) move around all flanges and welds, with the tip. you'll know the leak, when you find it. the post up top, is the same thing. a rubber tube/hose held to your ear, will amplify the leak, as you move it around the engine. it will be obvious when you find it. sort of like using a big screwdriver to listen for knocks. just making do, with what you have.

ive actually got a stethascope, just never tried using it to find exhaust leaks. if the rubber hose is the same thing, then ill just break out my stethascope sunday ewhen im down in the shop.

Exact same thing Doc, for us poor mechanics, I use a simple piece of 5/16"ID hose or tubing. It can be much longer than 3 feet and bigger diameter too. A small diameter tubing will transfer distint sounds when held real close to the tube. When you find the leak is is very loud in the tube and in your ear. Works the best for finding exhaust leaks. Try it your see. You don't even need the fancy ear peices and one ear is plenty.

Don't pour stuff down your carb or try looking under your car while it's running. That's not smart or safe.

You can tape the end of the tubing to a stiff wire and stick that wire anywhere you want from above, even between the four pipes where they join the collector. It works great.
