didnt you just build the engine? please tell me you didnt use stock rod bearings ?

IonNinja

Yep

Rod bearings were replaced with a new set of OEM bearings during the build.

usafcobalt

Stock rods??

1LowLS

Wiseco pistons,eagle h beam rods.

usafcobalt

Wow that's interesting. Sure your clearances were correct? Did you break in the engine with conventional for 750 miles? No boost? Holy **** batman. Just listened to the second video. That sir is rod knock if I've ever heard it. Put some Lucas in there it will quiet it up. But I would beat on it anymore. Time for another build.

sounds like a damn jack hammer

IonNinja

The issue isn't due to an assembly problem.

It appears to be due to an oil issue. I drained the oil and only enough to fill about 1/3 of my oil drain pan came out

Car didn't smoke so I'm not sure where the oil went lol. Honestly I'm just going to put in new rod bearings and hope i got lucky before I start looking for another block.

usafcobalt

Yeah blow by. I have that problem. Catch can solved that though. What were you running for pcv?

1LowLS

Mine did the same.changed the PCV valve in the intake mani and now have a catch can.all is good now.

Rings can't seat in an egg shaped hole.. Just sayin.

1LowLS

Haha

usafcobalt

But but but when I was a kid I made the square go in the circle. Just needed a hammer

1LowLS

His cylinders aren't egg or oblong.I checked by putting the piston in with no rings to make sure there wasn't excessive wear

usafcobalt

Well your no fun! All seriousness I hope some fresh bearings will straighten it out. Hopefully you didn't spin a bearing then you may indeed need a crank and or rods. Good luck man

You can't see a few thou, but your rings can. I'm not saying that was indeed the culprit, just saying if you didn't mic it, then you don't know.

1LowLS

Well I can tell u the piston had no slop all the way down the cylinder and the rings have quite some movement,with a freshly honed cylinder,I'm positive they seated.but ur right I don't know for sure,biut I'm pretty dam sure.his car would of been slower than before the built engine if they weren't seated.I know my motor had no power for about 50 miles until the rings seated,then went 1000 break in.

did you put in oil and see if it still sounds the same? when you first start running the engine you're going to **** through oil depending on the ring gap

IonNinja

Same as OEM. Hose coming off valve cover to intake

Yeah I changed the oil after I swapped the head, didn't make a difference.

usafcobalt

Yeah I would run a catch can in that system. What did you gap your rings to? They are supposed to be around .055. And with that gap. You will get blowby

Is rather have a little blowby than a tip-to-tip motor failure..

1LowLS

I don't remember exactly what they were at but they were a tad tighter than that.
Ok

ouch man that blows.. hopefully it's just the bearings and not the crank as well

IonNinja

so I pulled the pan off tonight and the rod bearings in #3 were completely gone, top and bottom

had tons of broken pieces of crap at the bottom of my oil pan

tried new bearings and its a no go, there's still slop between the crank and rod so either the crank and/or rod is out of spec

that sucks man. hopefully you get it back together before it gets way hot down there

IonNinja

Yeah, I don't even have a engine hoist to pull the motor so I gotta figure that out.

Wish I had a bike to ride around on in the meantime lol
