I would like to change the positon of my oil filter from standing upright, to having it at a horizontal position. This way it would not make such a mess when changing the oil.
I have a aftermarket adaptor, but my concern is if the adaptor might cause the oil pump housing to snap off from vibration and weight of the oil filter hanging at a angle.
The adaptor is a 90 degree that attaches to where the oil filter normally screws on and does not "relocate" the filter to some other remote location.
Has anyone tried it before?
Thanks, Glen

Glen, what kind of oil filter do you use, is it a filter with an internal standpipe?

By using a high quality oil filter with an internal standpipe and good drain-back valves, you should be able to avoid most of the mess, unless you have a problem with space and have to remove the filter at an angle.

If you don't use that type of oil filter already, you may want to try that before using a custom adapter. Some examples of such filters are NAPA Gold 1806, Wix 51806, Baldwin BT-216, Purolator L30137, and my personal favorite - Cummins Fleetguard FL3685. If your local supplier have an other brand, ask for a filter for Perkins engines, often used by Volvo, Caterpillar or Massey Ferguson in farm- and construction equipment.

Those oil filters will not drain after you stop your engine. The oil remaining in the filter, thanks to the standpipe, also gives you almost instant oil pressure at startup, thus increasing the life of your engine. It also eliminates most rattle at startup.

Any filter will spill some oil - there will always be some left in the nooks and crannies the valves can't control. Making it horizontal won't help any. They make "remote mount" adapters - one screws on the engine and gives you two hose barbs, then the other screws on the filter. This allows you to put the filter wherever you want and run hoses between the two adapters. Ideally you would mount the filter thread side up so any oil will fall into the filter when unscrewing it. If you're dead set on changing filter position I personally would rather do that then just moving it 90deg.

I hate making a mess as well when changing oil. Found an easy way to contain the small amount that dribbles out my filter (wix 51806, standard config pump / filter location in a 71 duster). I cut a plastic yogurt container down so its about 2" or so tall. With the wheels pointing straight ahead, it fits perfectly and stays steady on top of the idler arm. It also remains flexible to allow me to snake it out when I'm done easily enough. This contraption catches the oil before it hits the floor and anything else.

Mopar used a 90º filter adapter on the LA V-8s installed in the A-body. In the LA A-body, the adapter is needed to get a full-size filter to fit without interference from the T-bars. A "shorty" filter can be fitted to the V-8 without the adapter.

Once the seal between the block and the adapter is properly fitted, the adapter requires no more maintenance. In my experience, the adapter did not reduce the mess on the V-8s. My concern with the adapter would be how close would it put the filter to the inner splash shield. IMO, it would make a bigger mess.

On my /6 car, I put a food service pan (like you'd use when cooking a turkey) under the car to catch any spills. When I break the seal between the filter its attachment fixture, I stop and let it gurgle a bit before continuing to remove the filter. If I have a spill, I have a spill. I have rags, oil dry, and detergent to clean it up.

Unless you're lucky enough to have an Aussie slant oil pump laying around. With one of those, you only need the mountable remote filter adapter and a couple hoses.
