Removing Oil Filter

I've had trouble removing, in particular the factory fitted, oil filters on pretty much every engine I've done an oil change on. I read all the tips and tricks online about using gripper tools or even driving a screwdriver into it in order to get leverage.

The problem I find is the special tools rarely fit into the space available, and puncturing the thing is a god awful mess I'd rather not be involved in.

My solution that I haven't seen anywhere else I think is compact enough, and doesn't create a bigger project of cleaning up oil.

I attached a hose clamp as tightly as I could and then used the screw tightener housing as a hammering point to break the filter loose from the engine. It's worked like a champ the last three difficult filters I've had to remove.

I also draw a line on the filter so I can see that it's actually turning and the clamp isn't just spinning around it

(for some reason the filter pictures are upsidedown - whatever, you know what you're looking at)

Damned good idea, Loudmusic. Thanks for posting it.

Re: Removing Oil Filter

Is that really easier than just using a webbing wrench?

Re: Removing Oil Filter

If you dont have room for a wrench, how do you have room for a hammer?

I have a webbing wrench that I tried using in this location on my other engine (catamaran). I only had about 15 degrees of rotation that I could do, it slipped, and eventually just crushed and dented the filter.

On a Mercury outboard I again couldn't get the webbing wrench to fit in the available space. I was able to put a hose clamp all the way out on the end, rather than the engine-side of the filter, and I was still able to hammer it loose.

Use something like a nailset, socket extender, or screw driver. It doesn't have to twist in the space and extends the contact point out into the open so you can hit it with a hammer.

Having said that, I had a new vehicle and I needed to change the filter and oil. I was traveling and staying at a friends house. That filter would not come off. I was going to use the screw driver but I knew that would make a mess, and since this was not my driveway, I went to a quick lube place that was NOT quick. I did NOT have the good strap wrenches I have now. I think they would have gotten the filter off.

Using a hose clamp is a good idea that might come in handy one day.

But then that's just one more large single purpose tool to have on board.

Re: Removing Oil Filter

I have a collection of strap oil filter wrenches acquired over the last four decades. Ones with wide bands are the best. And they work best over a fairly limited range of diameters.

Re: Removing Oil Filter

The top down tool (above) generally works fine on spin-on filters. You should be applying grease on the rubber gasket when installing new filters. It makes later removal easier.
Another solution is a remote filter kit. It blocks off the original filter position and has ports for oil lines. And the filter mount can be pointed down so there's no spillage. You also can run a bigger filter. The bigger the filter, the slower oil passes thru and more dirt (smaller micron size) is caught. That's why on some big diesel you see 2-3 filters, dividing the oil flow.

Especially the strap wrenches that are made from a rubber like material. They really grip the filter pretty well. The metal band strap wrenches are not as good since they slip more than the rubber based wrenches.

Re: Removing Oil Filter

Sometimes just wearing good rubber gloves is just enough to get enough extra grip to spin it off without any tools. Clean it off first if it's greasy.

Of course you need to use lube (motor oil or grease) on the rubber gasket and don't over tighten it!

Re: Removing Oil Filter

I just grab and crush it a bit with large channel locks and twist it off.

When I install, I always put a thin film of dielectric grease (silicone grease) on the gasket. Works far better than a smear of oil. Learned this trick working on air cooled airplane engines, where they would get so hot that the oil smear trick didn’t do a damn thing. Trucks, cars, bikes, boats, planes...filter never gets stuck on.

Re: Removing Oil Filter

I'm going to add your radiator clamp (jubilee clip) method to my list of how to turn the damn thing when it does not turn. I usually get away with filter pliers, but sometimes not. Like you, I hate driving a screwdriver through the thing. And, C420 sailor, I'll try silicone grease, too. It is already on the boat, and in the garage with the cars.

Thanks guys.
