Re: Bypassing Oil Filter

The effective practice I used with changing the bypass filter was torqing the cover to 15-18 lbs ft torque. Over tightening the cover will distort the gasket and cause a leak.

Packard motors with the floating pickup avoided large particulates that will settle overnight and a key aspect of the system is periodic oil pan cleaning. The manual specifies an 8000 mile filter change interval and for a car that sits in the garage a lot that is essentially a lifetime filter.

So I would pay more attention to maintaining a good air filter and keeping the oil fill mesh wetted.

As well, recently I was a addressing a valve sticking question and I would use a multigrade oil in those motors to avoid oil starvation of the valve guides unless the motor has an oil pressure problem due to wear.
