Im not sour at all...i dont know why brad persieves it to be...look I can band aid it and buy parts im going to get rid of...or I can sack up wait a little longer and build the motor I want...brad it sucks what happened to your motor but you blow one up every trip...maybe if you tried my approach you'll build one that lasts...now my diagnostic on how the shavings got to the top and on the cam...all I got to say about that is the dizzy was very hard to pull there was brass on the gears   of the dizzy...ray im guessing as well that #6 is the culprit...the head was litely getting smacked...so everyone knows im not treating it like its the end of the world, just took notes on what not to do next time! And just drop the hypers already...even,the one that was bouncing off of the head is in great shape! You guys make it seem like its soooo bad well theres your proof...

You was running a pretty dangerously high deck height to begin with. That's, I think, why #6 decided it had had enough. Not seeing where it slapped the head, But guessed it from the trailer. Rod bearings are cheap. Pull it apart, get it hot tanked, reassemble with new bearings. I think you're OK.  As far as the oil pressure? i'm betting you spit a lifter or two or bent some pushrods......Probably #6.........Been there and done that! You didn't post pics of that.

Of more concern to me, once back tegether, is WHY the front cylinders look lean and the rears seem normal?  I'd be thinking about that......but then, I overthink things......  :banghead:

rod bearing gone = piston slap & no oil pressure

ring gaps aint gonna take out a rod bearing. the shit in the valley came right from the rod as it was spinning around. Ring were probably loose as this block was run fefore..i think. For every .001 you open the bore ring gap opens PI, which is 3.147.....Or .003. so it dont take long for gaps to open up wide. So if you've got .002 wear you've open ring gap .006. I wouldnt trust ANY mesurment from ANYBODY unless they measured with THEIR tools and use them everyday. I doubt there are very many people on here that could accuratly measure anything under a thou. I used to machine parts for HPs hard drive robotics and did some for the 1st space shuttle. Some of our tolerences were a hundred times tighter than any boat motor. we used to call automotive machinists, "blacksmiths". We had a machine called a CMM, computer measuring machine, it was in a climate controlled room on an isolated slab. It had a ruby sylist that came in and touched the parts all over and compared to print and gave a report on where the parts is in relation to the print. This was then an ISO-9000 certified part. Someone needs to get one of these set up for blocks. Another thing is you parts will change all day long as temps change if you wanna get real technical.

I set up a CMM at a location in Meadville, PA years ago......But that's not fixing Nordie's problem......

Spun rod bearing, probably due to the "no oil pressure" issue..........I see no evidence that the piston slapped the head.......Broken oil pump drive? spit lifter? could be a mariad of things. NO matter what, tear it down, get it all cleaned, then hit it with the hose and brushes, then reassemble. it WAS working! no need to rethink it.  Just think "why did I lose oil pressure? "  There is your WHY!

So what happens when you lose a rod bearing @ 5600 rpm? If I lost the oil pump drive would one of the    front cylinders be gone first? We already know what happened...why is the question...no offense ray but you are 100% wrong...besides the cam starting to go flat the upper area of the motor is fine...im betting bearing failure due to clearace and spinning 5800 on a stock lower

What were your clearances on the rods and mains? 

Post #26...you said you're pistons were 0.030 outta the hole....which...would require about a .070"
(compressed thickness) head gasket, preferably a bit thicker.  How thick were the headgaskets you used....what was the quench?

Did you use a gasket between the oil pump and rear main cap...or did you bolt them together metal to metal?  any sealer on the mating surfaces?  See what the OP driveshaft looks like when you get the pump off. 

You'll need more than 1 bearing gone to completely lose oil pressure.  I'm thinking the oil pressure caused the bearing failure, not the other way around.   If the bearing caused it, you'd have had a steady drop in oil pressure over the whole weekend.

crank rods and pistons were all balanced together...when i took my motor to the machine shop i told them what i wanted, and it ended up 3 thou pretty much across the board for both mains and rods! i researched on the gasket deal for the oil pump and main, but it didnt seem that i needed it i cant remember if i used sealant on it, but im going to say no, because 2 machined surfaces should mate...the head gaskets are .064 but there is only indication on one piston that it slapped the head...i know from the pics that it doesnt look that way, but if you see it with your own eyes it's clear as day

the oil pressure isnt completely gone...i started it a couple times in the garage as i unhooked the pump to make sure the loud bang wasnt coming from that or the crank pulley and i have about 12 psi

Just in case you missed all the smilies I put in my last post, I AM KIDDING, BUSTING YOUR BALLS, HAVING FUN. Now go take your shit apart and get it to the machine shop, August is coming fast.....

My #6 rod went out as well in my motor. After tearing it down and finding the spun bearing, I went to have it turned, just to find out there was a hairline crack on that journal  :sly: I would try and get that motor back together, it would suck even more if an even bigger, more expensive motor got trashed, but that's just my take on it. My bearings didn't overlap, they sheared the chunk off the back of the bearing and spun with the rod.

It's just gonna get hotter outside, get back on the water holmes  O0 Did the piston leave an imprint into the metal on the head? Or is it just clean?

Remember Jays motor w/ the cam 45* out? Bent every intake P-rod and smacked the shit out of the pistons....still runnin today. Guess we should have told him, "Dont try this at home".

Kinda where I was heading with it, but I think Josh is losing his sense of humour about the whole thing.  :beer:

I'm still trying to wrap my head around how the oil pressure dropped to nothing. Obviously the spun bearing(s) is the result, not the cause.

All the mains are focked.... but is it because of your spun rod bearing, or is the bearing failure from oil pressure beforehand :screwy:

Pretty sure #6 spun and then the rest is history...how this thing is still rotating is beyond me
