I helped Eric (MTownScout) rebuild and EFI a 345 for his scout 800A that Levi restored for him. We had it done with BBC valvesprings and umbrella seals, new comp cam and comp lifters, standard size bore and bearings, disassembled and cleaned the boat style rockers and 9 stand rocker assembly, the heads were gone though, refreshed the oil pump.....got it together and in, then broke in the cam, 50 psi oil pressure @2000 rpm, 25@ idle. it was a little noisy on the top end but nothing insane. well when we went to pull it out 2 pushrods bent! unstuck the valves, replaced pushrods and ram w/out the vcs. it was wet, but not pouring out oil.i removed the rocker assembly to make sure the holes were aligned and there was no blockages. all looks good, well then we thought a cam bearing was misaligned or the head gaskets were upside down... i ran the oil pump with an old dizzy and eric turned the engine over with a bar and when the cam "aligned" the oil almost shot across the fender! put the assembly back on and the oil instantly poured across the rocker arms. well.... ok started it back up..... nothing. still dry. took it for a spin to see if maybe it'd free up or something. well it started tapping loud and missing.... another pushrod???? we got pulled back to the shop and i was going to limp it in. i hit the key it tapped and missed for a second then got quieter and smooth out. i'm completely lost we called the rebuilder and he said he never heard of anything like that and said he's positive the bearings are right. he thought it might be an issue with comp lifters? when i run the oil pump you can see the oil pouring around the lifters and running down the valley and it peaks out at 50 psi never fluctuates. any suggestions? not sure what else to do before.... gulp... tearing deeper into the freshly painted 345. any ideas greatly appreciated!
