Exhaust sleeve

[100IH]

To find an exhaust leak, get a 24 In, piece of heater hose, 1/2" or 5/8". Hold one end to an ear and probe around near where the sound is coming from.

I do have exhaust leaks at both #1 and #2 exhaust ports The manifold has been resurfaced unfortunately the block was not at the rebuild. I suspect #4 is my ticking but would like to somehow seal the manifold and exhaust pipe to determine if it is the exhaust or a lifter noise as the noise does sound more like a lifter then exhaust.

You need a mechanics stethoscope or at least a long bladed screwdriver to transmit tappet noise to your ear, use the hose for manifold leaks. Sealing at the exhaust pipe will make it easier but that is not where you will find the ticking. Keep away from the fan or lift the belt off for safety!

The screwdriver trick did not indicate any particular cylinder or valve. There is some small lifter chatter that I can hear from under the hood. I know the exhaust leak is not the noise but I want to eliminate it to help look.

If you don't hear it coming from the engine with a scope or rod look elsewhere for a rattle. Cam shafts can rattle when the bearings are worn, but you would hear it with a rod if you are doing it right. the stethoscope is flawless.

Thanks everyone. There is some useful information here.

Now, make it all work. Get the right parts and go to town, you already knew what the causes were. Fix or patch & make do. Either you will learn and that's what is important. Best of luck daren, Say to James bond for me !

Short story. When we got our first home computer back in prehistoric times neither my wife nor I knew anything about them ( I still don't) . My son who is a computer wiz set the thing up for us. My wife's email was debbi07 I became daren007. My son didn't realize the curse he just put on me. I have been living with it ever sense. Then again possibly he did know and it was revenge for something in the past.

I am a airplane mechanic by trade and have been in the business for over forty years but somehow a simple machine like a model A kicks my ass.

Some machines seem to stick to common guidelines and some don't. Some try to be different just for the sake of it. Once you get used to the peculiarities your good to go. I started with Model A Fords at an early age. Went to General Motors then BMW then land Rover. Did an apprenticeship in auto machine as well right after high school. Even worked for U-Haul. After 1998 the government and California was calling the shots. No more consistant normal to rely on. Aint it fun?

daren, do you have the manifold gasket and metal gland rings? Getting those just right can help with a little leakage and perhaps prevent valve issues. Then tackle the exhaust vert. pipe bend to the manifold. a little muffler paste from the vendors can sometimes help at the flange mating surfaces. it's difficult to provide dimensions depending on your muffler and manifold condition. A sleeve was tried and discarded because it began to corrode in the manifold and tough to get out. We used one from the vendors after trying to find a transition piece at the local parts store. The vendor's required filing to fit properly in our situation.

I have the gland rings. My muffler alignment to manifold is not the best and not looking forward to fixing it. The manifold flare is not all that good either. As a temporary fix I have a sleeve with fiberglass rope for packing. Working so far.
