I have an amc 304, and just got done reading all the posts about oil pressure. Glad I'm not the only one with problems-- but wish there was a chaeaper solution. My problem is a little different, my oil pressure builds up fast when the jeep is started but then (about 70-80lbs) falls quickly to less than 10psi. My relief valve isn't sticking, at least not while it is on the bench. Could it just be the spring is losing its strength? Do you suggest buying one of the high pressure springs? And would I be wrong if I assumed that there is nothing wrong with the gears/pump itself considering it builds up to 75 psi initially? I just had it apart and am pretty sure that nothing is plugged. Any help would be great, thanks!
