If there's not enough flow into the lifter at startup to pump the lifters up, you'll get a bunch of loosey goosey pushrod action and it'll make a ton of noise and hammer the cam bearings.
You can switch back and forth between synthetic and conventional. That's not a problem.
Where's it leaking?

I have to be honest most of the questions you just asked are way above my knowledge of engines. I will check the gauges next time I am driving it. I am mainly just driving it around for fun and running the piss out of it from red light to red light and in deserted parking lots to burn a little rubber.
My plan is to lift it up this week sometime and get up under to see where the leak is coming from. All gaskets were just replaced in October. The engine manufacturer said it could be the full synthetic that's causing the leak. I personally don't know how much I believe that though. Engine was purchased and built by Skip White performance.
