502 Oiling issue
I just recently pulled the 502 Mag out of my boat. We rebuilt the engine, and sent it off to be assembled in the boat. I have been helping the whole way with the install, the only part I wasn't around for was putting all the accessories back on the block. I got the engine fired up yesterday and could hear a slight tick in the valve train. I let it warm up thinking maybe the oil was too thick and needed to warm up or it would just lube up and go away.
Well it didn't. the noise didn't get any louder, just consistent. So I revved the engine to about 2k RPM and the sound I think went away, but at idle I could still here it. So I pulled the filler caps of the valve covers and there was no oil in the heads. For some reason I'm not getting any oil on the valve train. I'm not sure what has happened. Maybe a hose is backwards, or something just isn't right. Boat makes 40psi at idle and runs like a champ. I'm going to pull the valve covers off this weekend but wanted to get the advice of some pros before going any further, or at least have some direction.
Rebuilt 502, just honed, re-ringed, re-bearinged, new pump and gaskets, the heads were slightly ported, and up graded to a 2.25 valve and better springs. stock cam, and accessories. the only things different are the CMI headers, and Valves/ Valve Springs. I put 20w50 in it, but my buddy argues it was straight 40w. I put inexpensive oil in it for run time and to flush after a few hours. Either way any ideas is appreciated. Ill be monitoring this thread so if there is any questions or info I might have forgot to mention Ill be here to update. Thank you

I'd look at the filter head,make sure oil comes out on the outside of the pad and goes back in the center.what lifters did you use and where did they come from.

I'm thinking a lifter isn't staying up

Shouldn't need push rods, but if you get a good set of lifters now, you can use them in the rebuild next year or so
