An "overtightened" oil filter

I've used Suzuki oil filters for the past 65,000 mile but on my last order they substituted Emgo 56-8566 filters. They claim they are equivalent and they do look identical right down to the round, not flat, gasket. The Suzuki filter calls for 2 turns after contact; Emgo 2/3.
When I stopped at 2/3 turn the filter felt too loose so I went another half turn, still almost a whole turn less than Suzuki. I rode the bike and it seems all right and no leaks.
My OCD question: has anyone here ever seen or heard of any internal filter damage from a modestly over tightened filter?

Never, unless the exterior is bent or dimpled. I use a Bales adapter and automotive filters, and I never use a wrench to install. I rarely have to use a wrench to uninstall either. Suzuki's recomendation is rediculous, especially since an O-ring requires less compression to seal than a flat gasket.

Tip: use moly grease on the oil filter gasket- it does not bake out/solidify as easily and makes the filter easier to remove.

Suzuki's recommendation for 2 turns works fine, but only for Suzuki filters. It isn't just the shape and size of the O-ring, but the compressibility. We have had posts from people having trouble removing an overtightened filter and from people who had filters leak from not tightening them enough. Both were due to not following the filter maker's instructions. I haven't seen any other problems though.

You probably don't have a problem with over tightening your filter. If you were to have a problem it would, most likely, be obvious pretty quickly.

When I read the instructions in the manual concerning the two full turns when tightening the oil filter, I thought I had misread it. Nope, that is what is in the manual.

Most filter instructions say to hand tighten until the gasket makes contact and then an additional 1/4 to 1/2 turn. Out of all the bikes and cars that I've owned not one required two full turns after gasket contact.

I was so concerned with the instruction that, even though I had a Suzuki OEM filter, I purchased a CarQuest branded filter and installed it [1/4 to 1/2 turn after gasket contact]. No leaks, no problems.

I've read on this forum that it is only the Suzuki OEM filter that requires the two full turns. I'll continue to use aftermarket filters.

i agree and

Also if you choose to put high torque make sure you are tuning
the crimp edge part not the flimsy body

When I recently did an oil change and read the 2 turns I thought it must be a misprint.

I used an aftermarket filter and there was no way I was going to do it up that tight and wreck the threads on the engine.

Motorcycle oil filters and car filters can have different bypass circuit pressures. Its not good karma to use a car filter unless you know or can verify its bypass pressure.

I can tighten an OEM Suzuki filter 1-1/2 turns by hand and the final 1/2 or so with a strap wrench.

There are 3 things that make a bike last. Clean air filters, clean oil filters, and quality oil. Saving a few bucks on a filter of questionable spec and performance is not good advice.

Just follow the filter manufacturers recommendations.. They've figured out how much torque you need to prevent the filter from leaking. There's a lot of difference between a flat washer on a filter and an O ring type like the Suzuki filter. The O ring type will require more torque to get them to seal properly.

I put a mark on the filer when it contacts the base and then tighten the recommended amount.

From one OCD guy to another: I've heard of gaskets being crushed, but nothing inside the filter. Like me, you will be paranoid about leaks for the first few days of riding, then that anxiety will go away until you see your oil level drop a little bit, then the left eye twitching begins again.

If you used your hand to tighten the filter as tight as you can, you will be okay. Unless you are Mr. Universe, I seriously doubt you can do any damage with your hand.

Hand tighten a Suzuki oil filter and it may leak. It's happened before. What's the problem with following the filter manufacturer's spec? Just remember the spec in the manual for two turns is only for the Suzuki filter. Other brands will vary from hand tight to maybe one full turn, not much of a difference across the non OEM spectrum.
