A few weeks ago my 95 ZJ (5.2) developed a pretty bad oil leak. After taking it to the local hack mechanic they told me that they couldn't tell me what's wrong without tearing the top half of the engine off. Here's the strange issue that I have now....The oil leak stopped and my oil pressure dropped to almost zero (according to the gauge). Normally without oil pressure one would expect to have a dead motor, right? Well, I've driven it for 2 weeks putting around 2k miles on it, and no knocking. It runs fine! WTF? I'm obviously getting oil pressure otherwise the truck would be dead.
--Oil pressure gauge reads almost zero. It shoots up to around 15-20 psi on startup though
--Oil leak strangely stopped
--It still runs great
Any ideas or help would be greatly appreciated.
