Easy Way to Cut Open an Oil Filter

Steve Pierce · May 4, 2021

[FONT=&quot]I always hated cutting open oil filters for inspection. Even had to make a trip to the emergency room for stitches once. My friend Jon Delamarter showed me this handy trick that makes it pretty easy.[/FONT]

What’s the best filter cutter to buy?

Had good luck with airwolf. You could just chuck it in the trash. You’ll never know you are making metal.
Other option is challenger re useable filter.

I like this one. One of my helpers exceeded it's design limits and they sent me new bushing and special shouldered screws for free.

Put it to good use last week when I noticed a few small flakes. Cleaned the paper media in a jug of Avgas and then ran my magnet around in the jug. Another cam and tappet set. Ouch.

Good point Ford. Engine monitors and oil filters just make you worry more;-)

I use that same cutter.... even uses it a few time on the car filter..

Latest engine making metal here is an 0-300 Continental... weird cylinder walls, looks like chrome is coming off..

Pic from the bore scope... several areas like this one... haven’t pulled it yet..

Good find, Brian, now that's a solid argument for routine borescoping. Did any cylinder wall debris show up in the filter? Please let us know what further investigation turns up.

Thanks. cubscout
