CAC tube cracked

We're looking at a 98 CC Allure. My wife recalls seeing a service receipt that indicated a CAC tube was cracked and leaking. The seller, an older gentlemen, stated he declined the service because he planned on making the repair himself. From what I've seen on the Internet, this may not be a DIY repair. Is there any way to determine if the CAC is still cracked and if so, how big a deal $$$ is it.

Cummins can inspect it for you, and hook it up to their computer. Give you a good feel for the total condition of the engine.

Is this the 8.3?

Good luck,

Gary.....You need to do some investigation. The CAC (Charge Air Cooler) is a large aluminum radiator with an aluminum inlet and outlet. The inlet and outlet are connected to the engine with rubber hoses. You need to find out if the receipt is referring to the aluminum inlet and outlet tubing that is cracked or the rubber hoses are brittle and have cracked.

The hoses would be no big deal and probably something that should be changed anyway. If the actual aluminum CAC is cracked, you're talking about an expensive repair or replacement.

Smitty, it's a Cummins ISC rated at 325HP. I had a bad experience at Cummins Cal Pacific several months ago. They missed two major items on a 2001 Newmar I was considering.

Don, I see your in So Cal. Can you recommend any shops around the San Fernando Valley. Benchmark RV does pre-purchase inspections but charge $500 for the mechanicals and another $400 for the house. Seems rather high. I'm comfortable with the house stuff but the chassis stuff concerns me.
