In the middle of a rebuild and my balancer won't spin freely. What I mean by that is that if I use the installer and install it till it stops pushing in the balancer won't free spin with me using a bolt and spinning it with a ratchet. If I pull it less than an inch out it will free spin again so the engine itself is not locked up but something with the balancer, any ideas?

Sounds like the seal on the timing cover is not pushed in all the way if you replaced it have had that issue.

you have to use the 2011 balancer if you didnt also since you have a 2011 did you swap the crankshaft tone ring from your old engine? if not you need to wont run without that found out the hard weay months back.

Apparently that's not necessary all 5.7 that in with t are interchangeable as long as u change knock sensors and crankshaft and flywheel check video out. I will use the 2011 balancer though thanks.

I hate to break it to you but i watched the same vid when i did mine its false I swapped a 2019 engine into a 2011 and 1000% confirmed its a diffrent tone ring not by alot just enough to cause issues also diff part. numbers. But hey if you still wanna go for it more power to you just know if it doesnt work motor has to come out and be torn down all the way again crank has to come out.
