Major engine issues!!!

Yeah cheers guys. It's a shame because whoever built the engine did a fairly good job coz I've stripped the lot now and they used real quality parts, but never had much of a clue about oiling everything and priming it all before running it. Noticed as well oil pump look pretty worn, explains the low pressure! I no I shouldn't spend money on a 4 bottom end rebuild but at the end of the day I'm only running 300hp so I'm not needing a hardcore bottom end. The compression is excellent and rods are perfect so it's going to get a crank grounding and new shells and new pump. Happy days guys thanks all for the help. I'll keep you all posted on the motor once it's sorted

I had the sump off after rebuild and pumped oil in where the oil pressure sensor goes and after a few pumps it was oozing out of all the galleries nicely so turned it by hand and job done

rubbish pic i know. but here is the problem now removed from my engine. the rear balance shaft bearing had destroyed itself leaving a large hole for my oil pressure to drop and the balance shaft just rattled around. i have now removed the balnce shafts and rebuilt the whole bottom end nso hopefully tomorow it will be running again.
