Should I be able to turn the crank by hand in my OM617?
The glow plugs and injectors are in it. It's a used engine I bought about 18 months ago.
Today, I started back on my project. I needed to turn the crank to get to the torque converter bolts, and I was surprised it turned without a lot of force needed. I was only using a 1/2" ratchet on the front crankshaft bolt. I thought the high compression would be a problem. Is this normal? Or did I buy a worn-out engine? Thanks.

A worn out engine would be easier to turn. They do take some effort to turn.

When I turned the engine to get at the torque converter drain plug, I used a 1/2 inch drive 27mm socket on a standard ratchet handle, what, about a foot long? Finding a place to have the ratchet handle where I could get my hand on it was harder than turning -- it didn't take that much effort.

Usually in my experience there are spots that are hard to turn and spots that are easy to turn. The hard spots are when the cylinders are on the compression stroke. If it's easy all the time, the compression is probably pretty low.
