i have an exhaust leak on my 8822re engine. i dont know where it is coming from all manifold and egr bolts are tightened. is it possible that the manifold warped

 

Turn the truck on, and feel around the manifold/block and then feel by where the manifold connects to the exhaust pipe, and so on.
You should be able to feel the exhaust comming out.

If the gaskets are gone, tightening down the bolts will do nothing.

 

i have all tha gaskets on and i felt around but nothing still. i dont want to run it too long cause i might burn a valve on my newly rebuilt head

 

How bad is the leak?

you should be able to feel the exhaust from the leak.

 

i am positive its only on one cylinder but it sounds like i am missing a bolt or two around a port. is there anything i could use to help me find the leak

 

you could use a peice of paper or somthing, go around the manifold and see if it moves.. or somthing similar.

I recently did some exhaust gaskets on a 90 silverado, you could feel where the exhaust was comming from easily.

 

it doesnt make sense tho i have a gasket there and i just checked, nothing around the manifold and nothing around the back. i am stumped

 

sea foam and have someone plug your tail pipe with their hand you will see the smoke from he sea foam come out from the leak

 

get a long piece of vaccum hose (or other small diameter hose) and hold one end close to your ear. run the other end around the area of a suspected exhaust leak. You'll be able to hear where it is.

As far as burning a valve. Don't worry about that. If you ran at highway speed with no manifold on it, you might burn a valve. There is no chance of that happening while at idle.

 

Check your header pipe at the "Y" those things are VERY prone to cracking, especially if the support bracket that mounts to the transmission is MIA

 

well i fixid the problem. i took everything exhaust related and cleaned the parts and put it back togather. i dont know what it was or what i did but i fixed the problem. thnk you for the help
