Didn't even know what to call this thread but I need help guys, I'm at a loss. Motor just went back in, heads/roller cam setup, new converter....First fire up went smooth no issue, no weird noises, good oil pressure. After sitting running for a while I was adding some trans fluid and it makes this loud screech, and the engine dies. It sounds like metal on metal but I'm not entirely sure, it's loud as hell though. Immediate thought was that the motor siezed, so I put a socket on the crank pulley and the engine turns just fine.
I drained the oil and cut open the filter and nothing, both are clean, no glitter, shavings or junk. Pulled the plugs, took a look at each hole, they look good, compression check and that's good. Pulled the valve covers and all looks well. Pulled the inspection plate and the converter and flex plate looks fine. So I button it back up, fire it up and all is good, couple short drives and it doesn't do it again.
Thursday I take it for a longer drive, and it runs great, shifts good, no stumbles, good oil pressure and about 30 minutes into it I stop at a stop sign after exiting the highway and it happens again, loud ass screech, engine feels like it's drug down or somethings binding and it dies, I tried to restart it, fires up, runs fine for about 5 seconds and it does it again. I get it pushed into a gas station, pull the accessories belt off thinking maybe it's a pulley or accessory seizing up. I try again, does the same thing.
My buddy shows up and I try again, same result, he said it sounded low and behind the motor, like near the converter/trans. He grabs his trailer and we get it to the house, it's a couple hours later at this point, roll it off the trailer, it fires right up, no issue and I drive it into the garage. Fire it up the next morning, it's fine, as soon as I pull out of the driveway, does it again. I have no idea where to look or diagnose next, any ideas and suggestions are greatly appreciated.
