Egt getting to hot.

did you pressure leak test the CAC ??

 

If the exhaust side of turbo is leaking oil the exhaust pipes are usually wet or there will be oil caked up around the turbo outlet.

I don't know what the boost spec is supposed to be but if its low that is likely the cause of high EGT's. I would do as suggested above and have CAC pressure tested and check all your intake boots and pipes for holes or leaks. Some trucks the intake boots rub on the insides of the hoods and cause them to fail.

 

Dirty air filter will cause high egt and oil consumption, but it would have to be really dirty.

 

Wow, I need to get out more often.....800 to a grand EGT is hot? I remember the 2 stick 3408 B TTA ( 650 ) showing 1250 plus pulling Grapevine. Owner told me no sweat til 1400.

 

Hell we call those pyrometers back in the day. You can kick and buy 1200 to 1450 at most with a steel manifold perhaps if you are toiling over Big Savage. You can exceed your thermal temp limits for a few minutes at most before damage sets in.

800 to 1000 aint gonna get me excited none. Warm yes. But not too bad.

That is one of the things I have always fought the computer #### over in my time. #### thing wanna get hot a little bit, let it. Computer starts pulling power no... not allowed. And something else cooks up usually what with all the aluminum coming in.

Engine pyro meter gets to burning, then the engine oil gets to really cooking that heat falls to the coolant temp gauge starts to climb and if you cook it too much you starve the turbo and when it starves it burns up and so on systematically until something breaks.

 

WHOA.

Do you see that massive rusted clamp behind the black ring towards the upper left corner? Aint you blowing all sort of leaking out of that?

You are very lucky Sir. Very lucky.
