Any suggestions as to how to remove a stubborn oil filter on a Yanmar 30. Have unsuccessfully tried several of the oil filter wrenches and am determined not to go the route of the screwdriver punchture. Thanks.
 
If all else fails go for the screwdriver. I have seen that as the only way when one has been well overtightened.

If you put a small plastic bag over it or a container under it and punch a hole in the bottom first the oil will drain out and it will be a bit neater than if you just start with the screwdriver.

Good luck, and I hope you don't need this as a fallback but you gotta do what you gotta do.
 
When you get ready to install the new oil filter, stick your finger in some new oil and run it around the rubber gasket on the new filter. That will help seal the new filter, and make it easier to remove when the time comes. Then run the new filter up hand tight, and then tighten one quarter turn.
 
I wish you luck! I had to cut one off with tin snips once, even the screwdriver puncture didn't work!
 
I have a tool here that best can be described as a big vice grip and is adjustable for all size oil filters.
I think it may have been a walmart item but I might have gotten it at Williams Oil Filters in Tacoma Wa.
You just clamp it on and put pressure. If it slips on the filter I just tighten a bit. Has not failed yet but
you have to have some room to use it in. Good luck Bob Heselberg
 
If the screwdriver puncture method fails you can rip off the entire top of the filter and stick a large Allen socket and remove the center screw that holds the filter on. BTW I believe filter sticking is caused more often by not oiling the filter gasket prior to install more so than overtightening. They can be unbelievable stubborn. At least this one is easy to get to. Try a Chevelle with the 454. OMG I was under there for two hours till I thought of the Allen socket wrench.
 
Thank you to all who rendered suggestions ... even to the Doomsayers who suggested that the screwdriver and hammer might ultimately have to be the solution. After trying most oil filter wrenches on the market, I found the six inch filter strap wrench by Performance Tool part number W173C.

The tool's concept is to wrap the strap around the filter and then tighten the strap by inserting a 1/2 wrench in the arm of the tool that extends perpendicularly from the the engine block and parallel to the filter ... thus tightening the strap and ultimately turning the filter.

At first I tried using the strap wrench with a 1/2 ratchet wrench with an average length handle and succeeded in only having the strap denting the filter canister ... it did not turn at all. So, it then became war .... I switched out the ratchet for a universal joint bar [so as not to risk damaging the ratchet] and "supplemented" the universal bar with a four foot pipe ... a little pressure on the pipe and victory ... the filter came loose.

The four foot helper was no doubt over kill but is all I had available [it was a bimini pole off the boat.] … but who can argue with success.

I agree that the cause of the stubborn filter probably was not over torqueing but rather was under lubricating the seal. Last oil change, I tried to save time by having the marina do the oil change … the time I gained then, I certainly lost this time around dealing with the resistant oil filter [although I referred to it in stronger language then “resistant” during the hours of fighting with it!!]

Thanks again to all, Brian
 
Brian,
Glad you finally got it off. With all the problems with removing the "modern" disposable filters, it still beats cleaning the filters that we had to do in the "good ol' days".
