« on: May 25, 2009, 08:23:22 pm »
I have a friend that has a 18hp kohler and everytime they start it up, with in just a few min it blows the oil filter ring off the oilfilter. what is causeing this???? could it be a compression release spring messed up or some thing??? Or could it be the oil pump it self????

I don't think it has any thing to do with the compression release. You could try to put a gauge on it and check the the pressure, but it would take a lot of pressure. It might be a warped on the sealing surface or a small crack.

I would think the pressure relief valve is stuck.It would take lots of pressure to blow the ring out
