My first trip with my '93 Winnie 22' Warrior w/Chevy 454 the oil pressure indications did something odd. Of course it always indicates 80psi+ when cold however after warming up it drops to 50psi. That's about what I would expect. However returning from S. FL I was heading up I-75 when I noticed the oil pressure was pegged at 80psi. This was about 30 minutes after I was on the road. The oil pressure had been running at 50psi. After and hour or so it fell back to its normal 50psi. Any idea what might have caused this?

First thing that comes to mind is a faulty oil sending unit, but since the problem is intermittent this is only a guess.

How old is your oil filter, what brand is it? What weight oil are you using?

Oil sending unit. I had two of them fail on 454. both went to 100psi and stayed there.

I don't have any info on that. I bought the RV from a guy who seemed to be pretty knowledgeable and meticulous about stuff. He told me he had been RVing since 1970 so I have to trust he knew what he was doing and was honest about it. He did tell me that the oil had been recently changed and synthetic oil was used.

Oil sending units are cheap and shouldn't be to hard too access and replace. I would replace it and keep an eye on the pressure.

I'd like to do that. Where is it located? Do I have to pull the dog house off or crawl around underneath it?

Not real sure on that year engine. On an older 454 I had, the sender was on the side of the block above the oil filter. Yours could be there, or on the top rear of the engine.

Thanks John. I'll take a look the next time I visit the RV.

My 1985 crawl under look up it is on the right side of the lower large pulley easy to get to just watch the wiring it is tied into the electric fuel pump

On mine, It is just above the oil filter. Its about 2 1/2 inches by 3 inches long. Has one wire coming out the top. Be careful about the threads. Thats steel and aluminum. Use Teflon Pipe tape when putting it back in.
