looking for a cat house to fix 2005 C15

That was the norm for mine. Ran great. then start throwing code s in the 90s. VVA stuff. Our mechanic could change them in couple of hours. But still amazed me that they could go bad in just a few months. Might get with Mr Haney on here. He could steer you in better direction.

 

You might try Cleveland Bros. just north of Harrisburg PA. Their shop in Turbotville Pa on Hwy 180 is second to none. I don't know about the shop at Harrisburg but it might be worth a try. I just know that you can't go wrong in Turbotville.

 

You've been to Toromont in Concord ?

 

They have a truck specific facility and they are excellent. I'm in Kingston and I'll do whatever I can to be sure they're the only ones that touch my MSX.
They aren't what you would call cheap at $125 / hr but these guys know their stuff.

 

Yes any cat dealer with a yard full of yellow iron usually has a truck engine shop. I'd visit the one closest to you and ask some questions. And as others have said their not cheap.

Sorry I didn't answer your question in the other thread

 

I am NOT looking to start an argument. Most CAT shops are good but there are others that stand out as being really great. Turbotville in the late 90s and early 2000s was just one such place. For myself Turbotville and one independent shop in NC are the only two shops that I have total faith in.
