Quote: You must have had air somewhere in the system. Now that you have gottne it out try putting onthe new oil filter adaptor. If it still doesnt hold a prime send it in for analysis
Now that I have the system working right I don't think I want to tempt fate and mess around with it. Thanks for the advice tho.
Hey! I've been having the same problem with the new style adaptor with out the filter bypass. The engine wouldn't prime with the new adaptor, put the old one back on an it primed instanly. Whats up with that? Could it be because I used the threaded piece from the old style adaptor that the oil filter screws onto, and the orignial style filter? I've heard something about metric threaded filters, but I don't have that type of fitting to try in the new style adaptor. Could that have anything to do with it?
Well, I've purchased the same parts as you all have...installed them and primed it with a bit of P.J., now i know you aren't supposed to use it but it worked wonders for me and as far as keeping prime, if I go out to her right now it'll jump rite up to 60 some p.s.i. like nothing. But, maybe i just got lucky?
Could it be something to do with the Oil Filter Anti-Drainback feature ?
When I first bought the AMC NAPA Gold Oil Filters I got the short ones,
#1258 = Fram #PH25.
Took'em back and exchange them for the long ones
#1049 = Fram PH11.
The longer #1049's did NOT appear to have the Anti-Drainback valve
which can be seen in the top of the shorter #1258's.
It looks like a red silicone rubber disc inside the outer holes.
So I kept the shorter #1258's since they appear to have the Anti-Drainback feature.
Do the longer ones have it, but it's just not visible ?
Seems this could have an effect on the oil pump keeping prime.
Do y'all that use the NAPA Gold's use the short one or the long one ?
