    Need some advice fellas. After changing the oil in my Skylark, I went to prime the pump. Well, the pump works real good, to the tune of a couple qts. on the floor. Blew the seal out on the filter(PF24) with my drill. When I broke in the cam last fall, I was getting 60lbs. of pressure @2000 rpm, which seemed kind of high to me. Did I get a bum filter or is my pressure too high? No road time on it yet, just break-in, white spring in the pump. I put a new seal on the filter and it did it again, not as bad but I can see the filter pushing away from the housing. How worried should I be?:Brow:

    That's kinda weird.:Do No:

    Seems like the only way that would happen is if there were some sort of restriction in the oil filter.

    Which way was your drill going? I think if you have an anti-drainback type filter and spin the pump backwards it would not allow the oil to flow...thus causing very high pressure in the filter. But I'm not even sure the pump would flow backward?:Do No:

    I like my oil pressure around 65 psi, 60 is not too high.

    My oil pressure is 80 psi cold, and about 35 after it's warmed up at idle. It goes to about 65-70 psi at 5500 rpm warm. I would think your fine. BTW, I would guess its a bad oil filter. A few years back after rebuilding a friends GS 400 we had the same thing happen. Put a new filter on and it was fine. That was back in the "high volume" pump days. :)

    I get 65 oil psi @ 2000 when the engine is cold, but as soon as it gets hot it's more like 30 @ 2000.

    Thanks guys, that makes me feel a little better. Guess I'll try another filter, after I buy some more oil and floor dry:pp
