Oil pressure problems - 93 Regal 3.8
Good morning. I'm new here and this is my first post.
Recently I've had oil pressure problems with a new, used engine I just installed. As the engine sat up for a long time before I bought it (from a salvage yard) I disabled the ignition, ECM and fuel injection and cranked the engine until I got oil pressure. Then I re-installed the fuses, the engine cranked right up and ran well. 30 seconds or so later I noticed 0 oil pressure and several quarts of oil on the driveway.
Searching for where the oil was coming from I installed a new oil filter and more oil and had the same problem. I discovered that the oil filter gasket was blowing out causing the leak. When I first cranked the engine over without it starting the oil pressure was more than half way between 40 and 120 (maybe around 80-90) on my gauge and slightly less when the engine ran and before I lost pressure. Suspecting the oil pressure relief valve in the front cover I am in the process of removing the engine to check that and to see if there was any damage to the bearings from when I had no oil pressure.
Having said all that, 2 things. First, if anyone would care to comment on my problem I would appreciate it, especially if you suspect there may be other or additonal problems than the relief valve. Second, I am using Fram oil filters (TG3387A). I have read several of the posts on this forum and apparently people here don't think to highly of Fram. That being the case, what filter would be recommended? My next choice would be ACDelco but I'm open to suggestions.
Thanks for reading through all this and for your help and advice.
