blownstang01 & Big Katuna,

Thanks for the info. I guess I can stick to my plans and start shopping for that early 2000's Prevost in 5 years or so! I can't afford a new one!!! LOL

B.K., I was thinking the pre-DEF units would be less problematic as well, that's why I was a bit puzzled, but your explanations do make sense.

Thanks again,

~Rick

The maintenance we have done is the injectors were cleaned and flow checked, and the intake Manifold was replaced due to a crack.


VERY unusual. Normally, it is the EXHAUST manifold that cracks???


Yer right my bad, it was the exhaust.

I’ve bought low miles (less tha 50K) ISC and mechanicall 8.3 engines for $5000. Put the ISC in a truck instead of rebuilding the engine in it...much cheaper. Add another $4-5,000 to swap so still less than half of a rebuild. I still have the 8.3 as I sold the truck it was the spare for. Good used engines are out there but you have to search and it can take months of searching.

Well that’s kind of my experience being around FLORIDA. My maintenance guy has a two man shop, $90/hr for RVs cheaper for trucks.. Nice shop, AC, pit. We are construction town around here. We shoot the poo when I’m in. He does a
Engine swap in dump trucks in a day once things are lined up. I didn’t ask price but had the feel it was in that ball park. These guys aren’t putting $30-$40k they don’t have into a 20 year old rig.

550 Cat rebuild in the Yukon will set you back $60 grand, just to stay away from all this electronic garbage that is out there, but your life can depend on it when a sensor goes south when it's -50 0n the Demster Hwy. Well worth it. A friend up there told me if the company wanted him to buy a new truck, he would quit driving, been hauling to Inuvik for 35 yrs.

Off the subject, but just curious: Wolfe, are you without an RV now?

Rather than new or crate engine. Look into used ones. COLAW inear Springfield, MO will quote a price on most anything.


Have a Diesel Engine Diesel RV Club

Have a Freightliner Yahoo Group or FCOC Web Page
