proper way to install oil filter ?
#21
When I try to screw the cap by hand with the oil filter I can never hand tight it completely. And I use OEM Delco and brand new cap. For me it is just proof that a resistance is added because the filter is not perfectly aligned inside.

You folks are over thinking this and some of your conclusions are wrong.
1st, it doesn't matter which way you install the filter. That's NOT when it gets crushed, twisted or whatever you want to call it. The filter gets twisted when you take it out after being used. That's because it has been soaked with oil and is "soft". So, when you unscrew the cap, the "soft" wet filter gets twisted as the cap rotates.
Yes, some of the better made filters may not twist (as it was stated above.)
I've used the cheap Fram filters before(twice they came out twisted)
Used the AC Delco's (one came out twisted, the other 2 or 3 didn't)

The Delco filters don't seem soft after use. Just did an oil change 2 days ago and the filter was pretty stiff.

Maybe it has to do with the car not being level. Once the filter is snap to the cap it can still move a bit. If it is being screwed there without being perfectly centered in its cavity it creates a stress on the filter. Let's suppose it is impossible for the filter to not be installed correctly, then it's the stress from the ratchet that damage the filter and cause it to collapse after some miles of use. My theory.
Either way, it should be possible to hand tight the cap until you can barely see the seal, then screw it with the ratchet (to the specification). The best possible way to insure it is done perfectly is by centering the filter inside its cavity first.

If it fits tight enough for an oring to compress, then it is automatically centered.
