Copper crush washer, what?

On the washer, everyone talks about it, but I've never seen a part number. I would just like to have a number in case my dealer doesn't know what I'm talking about. (Which unfortunately is highly likely.)

The washer that goes on the drain plug before you insert it into the oil pan. It comes with the vehicle and it should be changed regularly. If it is not changed or if it is missing-- the seal will not be tight and you will have leaks.

I've never changed any of mine on any of the vehicles I've had, unless I've L.O.S.T. it.

I gotta tell ya, that Fumoto valve is really nice. I went to a dealer to get a new washer and it installed perfectly.

It does hang down a bit but I haven't had any problems.

How long is the thing? I mean, who low does it hang down from the pan?

I'm doing this from memory but I'd say maybe an inch, maybe two?

If you are doing any serious off roading you need to have the tranny skid to both protect the FUMOTO and the oil filter. The oil filter is pretty tough and would survive most mud or soft ground impacts, the FUMOTO would be ok in mud, but clumps or hard dirt could break it if hit hard enough. I would invest in the tranny skid even if only driving on gravel. Actually I would have the tranny & transfer case skids if it was never off the highway like ours. Road 'gators can be rough on a vehicle, one did $2000 damage to the Magnum this past December. Lucky fo me the oil filter is mounted above oil pan on front of engine, and the engine is high in the engine bay designed for 6.1L V8 and just had a couple of light tread marks on the pan. Needed some suspension parts, new lower engine cover, a/c condesor, front bumper, grill and front end alignment.

Are you speaking methaphorically, or did you actually hit a "gator"? You sig say swampeast? Are there gators in SE Missou?

Hahahahah!!! No 'gator's that I know of, "road gators's" has always refered to semi-truck treads on the road way, first heard it called that in the '70's in SC of all places by a GA boy who I worked with at Ft Jackson. SE MO used to be a swamp before it was drained. I still remember the cypress tress and swamp rabbit hunting. The draining started durring the depression and was started back up in 60's I think and has been pretty much completed and all the swamp area's have been turned into farms for cotton and rice mostly. There are networks of drannage ditches/cannals and hold ponds all across this area. Thanks to the popularity of rice farming in this area the dreaded blood sucking mosquito is back with a vengence after almost disappearing in the late 60's to early '70's due to loss of habitat.
