It definitely should be. It may just be their one in a thousand that is not. We'll see how they handle it. Before You put it together I would check both the Cover and the Housing with a Straight Edge and make sure they are both Flat and Straight..

I wouldn't use any type of gasket sealer.. It could migrate into the pump and possibly the relief valve. But thats just me.

I called Precision Oil Pumps today and they are sending me a new oil pump bottom plate gasket. I was told not to over tightened the bolts as this distorts the plate. He told me not to use silicone sealer. I have some old school Permatex that should do the job.

I emailed them through their website and explained the problem. So far no response. I assumed a "blue printed" oil pump was superior to one out of the box. Perhaps not?

Go to their Website. Interesting Reading. I would hope Phil's Pump is a One off poor Assembly and not an Example of their normal Product. .

Finding any oil pump cover bolts loose and especially if they had been safety wired suggests a problem during the original pump assembly. Being on the engine awhile may complicate a warranty return but regardless, the vendor should be informed and there’s a chance they will want to see the pump and make it good. If you’ve broken the safety wire to tighten the bolts, you’ll have to let them know this as that too could complicate a warranty return. As already mentioned and assuming your oil pump is a spur gear design, it will have a thin gasket between the pump body and the cover. Once that gasket failed, it’s unlikely that simply tightening the cover plate will stop the leak until the gasket itself is replaced. If the pump cover has been over-tightened, then the possibility exists that the oil pump body may be distorted at the threaded holes at the gasket surface. The gasket is thin and it wouldn’t take much distortion to create an oil leak. If that’s the case, then disassembly of the pump and running a knife sharpening stone over both the body gasket surface and the cover may help in removing any irregularities that exist. A flat surface with wet/dry sandpaper can also accomplish the same thing. Be sure the rotors turn freely after retightening the cover to the pump body.
