engine rebuild

Rebuilding the engine I decided to rebuild both oil pumps but the secondary oil pump cover is to tight to fit easily over the gear. It also once put together prevents the engine from turning over by hand. Is this normal or is the oil pump cover not made properly on this replacement kit.

First time using this forum so I'm looking forum to this. Anyways, I have a 2013 GTX 215 I bought for $1000 that had a bad output sleeve driveshaft and motor mounts. I replaced all broken items did an alignment and all was running well for the next 15 hours. Went to change the spark plugs and...

I recently rebuilt a 787 engine and am now doing a second engine. The rebuild kit has a crankcase to cylinder gasket. The gasket has no cutouts for the PTO and Mag side holes on the crankcase. Water doesn't flow through the crankcase but there would be heat transferred to the area if water was...
