On our Royale we lost the engine several years ago and then went through a nightmare of cascading failures for subsequent engines until we finally found S and J engines in Spokane, WA. We installed that one without reusing anything that touched water or oil. That proved so far to be a great combination and that coach is always ready to go anywhere at a moments notice - like taking us 8600 miles to Alaska and back last summer.
Based on that very positive experience we decided to preemptively replace the engine in the Clasco which was running just fine. Our logic was we will probably will continue our GMC adventures for another ten years before we age out so somewhere in that time frame we would have to change the engine anyway, so why not do that earlier rather than later. Even though that engine had not failed, we decided to follow the same strategy and replaced everything that touched oil or water. We also replaced everything that moves on the outside of the engine. The marginal cost is not all that much more and you get a lot of certainty for that relatively small premium. Between a correctly remanufactured engine, a properly done engine installation and the FiTech EFI the Clasco drives like a new motorhome while being a lot better built than any new MH anywhere near this size or cost.
If you do your homework selecting an engine rebuilder, buying the new radiator, hoses and other external components, and find out from Jim what the labor cost would be for the R&R I think you will be shocked at how relatively economical this is to do. If you plan to keep your coach for five to ten years I think you will find this a no brainier decision.

A wise person once told me " You can get 20 years experience once, or, you
can get 1 years experience 20 times, the choice is yours." How many times
are members of this great GMC community going to experience catastrophic
engine failure caused by crap from the previously failed engine lodged in
the lines and oil cooler. A rattle can full of carb cleaner will not clean
it out. Neither will an ordinary air compressor "OSHA APPROVED" air nozzle.
You are better off removing the stock oil cooler and running without one. I
have no experience with the machine that Rob talks about, but S and J will
not warranty any of their engines unless new hoses and brand new previously
unused coolers are fitted. That is what I do when I install new engines. On
Jerry Work's Clasco coach that I installed an S & J engine in, I even
replaced the radiator with an aluminum one. Ask Jerry what he thinks.

I fully agree. To me it is just cheep insurance.
I am going through a Patterson rebuild. This should be a once in a lifetime engine change for me.
So new radiator and new external oil cooler and new everything else that touches oil or water.
But I'm anal.........

Well, as the commercial says, "You can pay me now, or pay me later to do it
the way you should have done it the first time!" A thimble full of blast
media, or machine grit from the overhauling processes, will absolutely
destroy a new rebuild in a couple of minutes. You cannot be too clean when
doing engine swaps. Jerry Work sewed up custom fitted cloth slip covers for
the interior of the class coach to protect the plush pleather interior.
Guess he thought I might have dirty hands or something. I went through a
box of nitrile gloves on that coach. Everything was stripped and painted
with very durable hammerite engine enamels. It still looks better than
factory. If you have to ask yourself "I wonder if that part is clean enough
?" you already have your answer.
