C15 High EGTs

Just a thought, have you double checked the gauge for accuracy? That 1500 seems really high, I haven't had a pyro gauge for years but that's almost catastrophic failure temps.

 

How about swapping the whole elbow over? At 1500* you'd have some major failures going on.

 

Water and oil temps normal?

 

Verifying the reading is the first order of business, nothing like throwing money at a non-existent problem. Severe exhaust restriction and remember Pete air filters get dirty on the inside and not the outside like most.

Edit to add - It's not uncommon for the exhaust sleeves to fail at the welded seam and the pieces to take out the high pressure turbo.

 

I would say if every thing on the air side checks out problem may be on the fuel side. Could just be dumping to much fuel to the cylinders. Good Luck

 

Plugged radiator and CAC not letting air flow properly?

 

$75 inferred heat gun? Good for many other uses.

 

Hot cast usually puts off a little smell. I used to have a E we played with just above 1000 it would let me know. I would have to know no doubt. She won't live long with that heat. Since he referred to the elbow I can only assume the probe is post turbo
