Hola guys. It's been awhile since I've been around, but I've finally got my cat up and running again.
I've got a wierd oil pressure issue with the new engine, and wondering if anyone here has some insight/different POV?
On cold start, engine will go straight to 40Psi, and hold nicely. Once warmed, pressure will fluctuate between 20 and 0Psi If the engine is fired cold and revved or allowed to warm and then revved, oil pressure will hit 50-55Psi at 2K rpm, and climb from there, hitting a max of around 70.
When the motor went together, bearings and oil pump were within spec according to Ford service manual. Engine was primed before initial firing, etc......
I'm just kinda at a loss as for what to do next. I know I can pull the K-member and check the bearings in about a day, but don't want to unless I absolutely have to.
Anyone else have any suggestions / input?
BTW, oil is 10-40 non-synthetic.
Thanks,
Andrew
