Mid/low 13sec 5.0 project (new video and pics 7/11) Reply #660 – May 30, 2009, 05:37:59 PM Engine came out today...no real leaks or anything to speak of, which is awesome. May tear into it a little bit tomorrow before work to get a sneak peak at what could be wrong. I'll keep you all updated. Quote Selected
Mid/low 13sec 5.0 project (new video and pics 7/11) Reply #661 – June 03, 2009, 01:59:44 AM Engine is apart...rod and main bearings are FUBAR, everything else seems to have made it fine though. Looks like the crank wasn't quite right somehow...maybe didn't fit perfectly in the block, we can't be sure. It wasn't the crank that came with the block; the crank that came with the engine was too far gone, so we're wondering if just this crank didn't quite fit perfectly somehow since the crank's wear spots are only in certain places as opposed to full rings that go all the way around it; even though when we built it, we plastiguaged the clearances and they were good. Who knows. Quote Selected

Which would also explain your viberation issues... Did you have the block aline honed before installing that crank?I wouldn't say the crank was BENT since the vibration didn't occur until after 1000 miles. But a loose, wiped out rear main bearing seems to be the most obvious culprit.And no, the block was not aline honed as far as I know. It definitely will be this time around. Quote Selected

Mid/low 13sec 5.0 project (new video and pics 7/11) Reply #667 – June 03, 2009, 02:04:06 PM It's kinda one of those "Did the chicken come first or the egg?" situations. From the look of the wear on the crank (at the middle thrust bearing), it looks like it may not have been a 100% perfect fit, which caused uneven wear, killed the bearing, killing the oil pressure, killing other bearings. That's the hypothesis right now; it's all going to the machine shop for professional buttstuffysis. The cam and cam bearings all look fine; all the big wear is in the rod bearings, main bearings, and crank. Quote Selected

Dad has a long history with them and they've always stood behind their work so I don't forsee any problems.As far as the aline hone, they may have done it for standard procedure; I can't remember them mentioning it though since maybe it's just assumed.

Mid/low 13sec 5.0 project (new video and pics 7/11) Reply #672 – June 04, 2009, 05:25:23 PM Dropped everything off at the machine shop today....block, pistons, crank, oil pump, oil filter, flywheel, pressure plate, etc. He's gonna take a look and see what went wrong; his first thought is that something may have clogged an oil passage somewhere since the engine was getting very good oil pressure at first. I already told him that I want it align honed, making sure the crank fits just right, and the WHOLE assembly (balancer, crank, flywheel, etc) get balanced. Taking all precautions...and I thought I was buttstuff the first time around. Quote Selected
