RVing is enough work and problems as it is. You have picked about the worst "disposable" Light Duty diesel engine out there. To add insult to injury: the Asthma Attack turbo GM ignorantly slapped on the engine gives you the fuel economy of a 454 gas engine working that hard. This engine and...

Have you set or verified the warm engine idle speed? Offhand a stuck relief valve in the "new" oil pump. Because I deal with extreme heat: when the oil pressure is down measure the pan temp with an IR gun. It may be overheating it's oil. I would sample the engine oil to make sure it's still...

Unplug the compressor coil and see if it's still trying to turn the compressor hub, part on front that's slowly turning.

Is the A/C on when it makes noise? Take the belt back off and spin the compressor pulley by hand if you can. It's either a locked up compressor or locked up bearing in the pulley.

The High Pressure switch is either a (most likely) retrofit to R134a or a Factory 134a system. 1993 was a weird year for that I read. This compressor will immediately start leaking again like it has in the past. The black buildup of dirt is sticking to A/C oil that leaked out. The body orings...

As you walk around a parking lot one may notice the lack of noise as the vehicles equipped with this CS-130 firecracker are less and less on the road. Must have been there to warn pedestrians. Just charging a run down battery was enough to push them over the raged edge of the thermal envelope...

Just replace it now. The R4's are good for maybe one season before they leak --> run low on refrigerant --> fail to return enough oil --> debris glitter bomb the system as a courtesy --> Lock up or make noise. Maybe in less extreme temps they make it two years. Seriously post a picture of...

Blanket and the wrapped the: crossover, manifolds, and downpipe past the bend in the passenger floorpan. This was to keep the underhood heat down and prevent burning the paint, again, on the passenger floorpan. Wrapped the manifolds to keep injectors cool as I ran the 6.2 heads. Any blanket...

Explicitly: HELL NO! Unless you are into S&M and say like doing the job over and over again because of shit no-quality beyond cheap parts from a company that fires a veteran for stopping a robbery under their coward "No Hero" policy. The burning small and smoke from this Autozone POS reman...

Orifice Tube.

I run the Discount Tire slightly different version, ATP II, of the Coopers. Yes, they are quiet ... except when run flat giving you enough warning to get stopped before they come all the way apart. They ride nicer than the Trashforce Firestone RAM pickups come with. They last longer than them as...

Get a genuine Sanden replacement. I find the clutches cost as much as a new compressor so buy a new compressor and: replace it or swap just the clutch off the new compressor. Evac and recharge will cost more. IMO replace the compressor as the 1st vid noise is loud enough to justify it even if...

Anything on the belt drive is affected by changes to load on the belt drive. PS pump changing the load make may another item make noise or not. Remove belt and feel every bearing by hand. Sample the PS oil. Assume it's at the proper level?

Why this RV for full timing? Can you change an engine in the RV campground? No not simple repairs but the engine cracks the main webs and what's left of the crankshaft is sitting on the road. Or cracks the heads and you are pulling heads off. Read the adventures of the member I linked... :eek...

Wait till they get to the forgotten diesel, the 6.5TD, that I biased my above comment on. I didn't think it was the transmission the OP couldn't get help on... 🤔

I think you need a reality check. You expect about the 2nd worst Light Duty Diesel Engine GM ever made, to follow up on the actual all time worst the Hand Gernade Oldsmobile Diesel Disaster that put Lemon Laws on the books here, to hold together and run? Worse minor problems will strand you with...

It will eat those afterthought OD units too. Many HD MT's to choose from out there. At least try for a NV5600 with the lube mod done to it, but, many better MT choices out there. If you do something really bad in life after you die you may come back as say Bed Sheets In Las Vegas or a...

I suspect the OP's currently figuring out how to "recover" from a serious and expensive equipment failure like this. It's an expensive lesson in balance/overloading that may simply put them out of business on the spot. Overloaded and/or improperly loaded isn't asking one's wife to set their...

Running out of fuel does weird stuff like revving. Flapper in hose. Your pressure gauge should also read vacuum. I have had these engines "Vapor Lock" pulling against a restriction like clogged tank sock or a softened hose that kinked shut. Tank lining coming off clogging tank sock.

What rig (pickup looks like) and trailer are your using? A few of us have attempted this. IDK how many aside of myself still show up. Happy to give out advice. Warning: Look at the Carnage Thread I Won because hotshotting with a 6.2/6.5L IDI GM Diesel... It can get expensive in parts quick...
