Multiple Oil filter Blow Outs

[NO_H2O]

The oil pressure from the pump is not regulated untill it comes back to the case and hits the spring/piston. Cold start up oil pressure can be very high.
The K&N HP3001 has a burst rating of 600 psi and the seal is crimped into the case 360 deg. around the seal. Some filters just have a groove for the seal to sit in. I had problems with this on cold start up untill I changed to the K&N HP3001. Note the Mobil1 filter is made to the same spec. in the same plant. It just doesn't have the handy hex welded on the bottom. I have not had any issues since I changed to these filters.
