How do you know the can wasn't touching or a hair away from touching? Someone here had a P-style base gasket blow-out on a cold start and it came down to the filter probably wasn't installed tight enough as the cause.
You could say the same about a lathe cut as well.... I just dont see the need to crank them down that tight like the OP's pdf suggests.
Who?
Like said, it's not really "cranking them down" if the filter just touches the filter seat with 3/4 turn after initial gasket contact. Following the directions on the box or can will give that result or close to it. I certainly wouldn't leave much if any gap between the can and seat with a P-style gasket.
I went back and found the thread ... my mistake, it was a flat silicone gasket and not a P-style gasket. But the conclusion was the filter was probably not tightened enough and eventually blew out of the groove on a cold morning start-up. Same thing could happen with a P-style gasket too if not installed properly.
This person was using a Pentus filter with a lathe-cut gasket, not a P-style gasket. They later posted they hadn't tightened it correctly.
Yeah, see post 14. There was all kinds of P-style gasket discussions going on in that thread too, so probably why I thought it was a P-style. I had to go find that thread to verify. Same thing could happen with a P-style gasket if not tightened down enough.
So that means in order for the two metal contact points to touch the engine, the P gasket has to flatten out a little bit under pressure; correct?
