Brand new engine..builds maybe 10psi at 2krpm then 0 at idle..
So I fired my engine for the first time tonight and the car built maybe 15psi of pressure at 2k and when the revs came back down the pressure drops to 0. Gauge works correctly(verified)..the lifters are getting no oil whatsoever neither is the top end of the engine. Possible causes?
Im running a Mellings hi volume pump with the spring that came with it installed(hi pressure hi volume). I let the car idle for about 30 seconds twice..and it was so bad the car started to backfire violently(guessing its because the valves are barely opening)

When turning the engine over with the rear oil sender out oil seeps out of there slowly. One thing I didn't do was soak the lifters but it still should of had something after running for 30 seconds. The car was popping and BAD. ALl the rockers look almost level (no oil in lifters)
Put the plug in the hole and the pressure shot right to 60psi. It took about 45 seconds for oil to start coming out of the rockers but there's oil. The car also sounds like is has the 262/266 cam that I put in instead of a stock can. Let's just hope there's no damage.
what is this rear plug you talking about? i tried to prime motor today and it wouldn't build any pressure at all.
Here is what it looks like and it installs in the back of the block. There should also be a small freeze plug type of plug in the front of the block, under the timing cover off to the right of the cam.
