Had my engine rebuilt last year by a reputible local machine shop. I've probably run it 20 hrs and I had a carb issue (stuck throttle). That got me to looking at other things. Popped the valve cover and the top of the engine is bone dry. Good oil pressure at the gauge (on oil filter housing) so I know the pump is making good pressure, but its not getting upstairs. The line running outside the engine block to carry oil up to the head is clear (ran wire through it and blew air trough it).
Any ideas as to what is going on here ? Any thoughts would be really helpful. I'm really worried about the $$ and time invested here.
Thanks for your help!
