Do you need to change the O-ring on your oil filter?
That same O-ring needs to be changed along with the oil filter. When you buy an oil filter, it also comes with a new o-ring that goes on top of the filter to provide a seal. This o-ring wears-out and breaks relatively quick, which is why it needs to be changed out with the filter cartridge regularly.
How to seal a new cartridge oil filter?
When the new filter is unboxed, use the old O-rings as a basis of comparison when looking at the new O-rings. Apply Oil to the O-rings: Always apply clean engine oil to the new O-rings and the O-ring grooves in the housing cap. This helps to create a better seal because the O-rings will not bunch up or twist when the housing is installed.
What happens if you tighten your oil filter?
Over tightening the oil filter can either strip the threading, or break the O-ring. If the O-ring is broken, this can cause the filter not to have a proper seal; and cause oil to eventually leak.
What causes an O-ring seal to malfunction?
Problem sources: Like a sponge, the seal absorbs the surrounding fluids and swells to the point of malfunction because of incompatibility between seal compound and system environment (i.e. chemical incompatibility, high humidity, etc.). Suggested solutions: Select an O-ring material that is chemically compatible with the fluid it will contact.

Why is my oil filter cap leaking oil?
Typically, an oil filter cap is threaded and sealed with an O-ring and may not seal properly if over-tightened or cross threaded. This may result in oil leaks and low oil pressure. If you notice oil leaking around your oil filter cap, remove it and inspect the cap and O-ring for damage.

What happens when you take old oil filter off?
Also, when you take the old oil filter off, you need too make sure the old O-ring came off with it. If not, the original O-ring will blow-out and break the seal upon starting the engine, then cause a leak/the engine to stall.
