I work in the industry too, and I can only agree with you that there are too many examples of bad work being signed off as good work. I will never forget the guy installing an S92 helicopter tail drive shaft using his calibrated arm aka german torque wrench. I dont mean to specifically knock you or your abilities as I know nothing about you. I just have strong feelings about this due to my observations in the field. My point still stands that we should not educate people to do the lesser safe thing. The torque is typically around 18-20 ft-lb, and it should have safety wire.

Just as an FYI, oil filters are 16-18 ft lbs.
I rarely (almost never) use a torque wrench on an oil filter, I just use a wrench.
If someone has been doing maintenance for 20-30 years chances are they can hit a torque within 5-10%, a torque wrench is only accurate to 4% (if freshly calibrated).
I still torque critical items and spark plugs (hate to pull a heli coil out) but there are still many spark plugs (and lots other things) that youi simply cannot get a torque wrench on so you have to use an alternate method.

3/4 + turn after contact is within torque spec's, and far easier to do on an RV.
Just like it says on the Napa filter.........

Guess you need to keep up with the latest technical bulletins
Tempest installation torque: http://www.aeroaccessories.com/oilfilters.html
Oops, sounds to me like you've been overtorqueing your filters.

"owwwwwwwww, somebodies closer"
I bought a 1515 oil filter today to size up on my 8A. I have an airwolf remote mount that is on the lower starboard side of the firewall, the 1515 is about 1.5 inches too long, is there an equivalent napa filter to the 1515 that is 1.5 to 2 inches shorter that I can use. After I put it on by hand, turn it tight till I am satisfied, I will be moving on with my life, the end!

Thanks Walt, those are good links. The old torque specification is still ok per that champion SB you linked, so maybe the lycoming manual is still good this time. But this is all good information to have out there, and the moral stands true, follow the specs. Of course my lycoming manual is probably out of date haha.

I measured it with a torque wrench. 3/4 turn after gasket contact is 18-20 FTLB.

And just using new engine oil on the gasket, I have never had a problem removing a filter with the proper fit band wrench.

Yep...... 1068 is just a shorter version of the 1515. Much more filter area on the 1515.
That information and torque spec's are all here in the above posts. If you are going to run a Napa Gold filter, I would suggest that you start from post 1 and read to here..... Lot of good information. Don't miss any "go to" links.....
