This is a small problem but it's got me. I put oil in my MH the other day and forgot to put the cap back and I lost it on the road. Does anyone know the part number of a replacement. I have an 04 Winne on a W21 with 8.1 engine. Any help would be appreciated.

Check parts houses and you might check for one to fit the 8.1 as I would think the cap would b an OEM item unique to the engine and not the Winnie.

Until then, stuff a rag in the filler pipe.

You know the strange thing is the engine used to use a qt. of oil about every 500 mile and with the oil cap off it uses no oil and there is no blow by. Your right about putting the rag in it till I can find one. I done tried two caps.

If it quit using oil with no breather cap then you have a sticking PCV valve. Time to replace t. If you are cheap, like me, you can soak it in lacquer thinner and get the gunk out and put it back on.

Did the same thing! lost my oil cap on my W20, 8.1. Stopped in at Westfall GMC Truck, Inc. parts department in Kansas City, MO, (816) 455-7262. Purchased a new one, no problem. was like $14. Part # for 8.1 workhorse oil filler cap is ACDelco 12574265 / ACD# FC210 and Winnebago W8800701.
