Here is one for the books. I have a 1992 Ford Van with a 351 Windsor. 110K on it look and runs great...... But when I change the oil the filter is dry, that's right no oil in it. I have tried a couple of different filters and have gotten away from Fram (bad news). I have plent of oil pressure. I just changed today and dry again. This time I forced compresed air up both holes. Had a hard time sealing the return, but got air up the feed in the middle. I will pull the filter in a day or two to see if that worked. The center has a big hex in it, but I dont know what will fall out if I take it out. Is there an internal bypass ?? I have been changing my oiul often to compensate.

Help !!!

Have you tried starting it without filter ??? Don't do this on your driveway...

No, sounds messy, but it might just prove if oil is flowing, were does the oil come from, the sides right, output is ther center. When I put compressed air up the center, I didn't get much air in, maybe the inpuy is clogged

I doubt you would be able to blow air through oil pump? Esp if its in good nick...Are you using Z9 style filter ?
