Have a 97 Magna 40' with that engine. Very hard working engine. Good milage considering we tow close to 10'000#. Had a few bugs due to lack of service. Once those have been taken care of it is a great engine. Could require a turbo if the other has been abused and not allowed to cool down proper. The turbo boot into the engine is pro to opening a seam dumping the boost. That will cause loss of power and heavy black smoke. I have a better fix then factory. Then there were all the other things that a unused coach will have problems. After all the bugs were fixed it is a great running, fun coach to drive. If priced right and you can do some of the work it may be a steal.

Isn't that the 2-stroke V-6 engine that some say is prone to leaks? I saw a Magna advertised with a rebuilt Detroit where the coach had less than 150,000 miles?

I have a 40' 1998 Magna and it is a reliable vehicle with adequate power to handle mountain driving towing a CRV. Like any 15 year RV we have had our share of maintenance issues but the two that relate to the chassis and engine are:

1) Failed turbo requiring replacement of turbo and injectors,
2) Fuel tank rusting and sludge requiring removing and repairing of tank. This RV, and probably many others, has a non-aluminized tank that is subject to rust if water is allowed to condense in a partially empty tank. This was a tough and expensive problem to solve.

The engine is really a Navistar DT530 that was built for Detroit Diesel as a Series 40 and has not been a problem other than noted above.

Hope this helps. Good luck.

Our 97' had rust in the tank. I used this:

And this:

The rust cleaned up and now have a clean filter

Have you had problems with the 90 degree boot on top of the motor for the inlet opening a seam? Loss of power and black smoke is the result.

I always keep the tank full and use Biobar As an additive when I sit for any length of time to eliminate algae growth. I also change filters pretty frequently.
I have had a problem with the rubber boot and replaced it a couple of years ago.

Thanks for the tips on additives, I'll give them a try.
