feeler gauge is cheapest tool to check thrust clearance.

I wouldn't use that crankshaft with scratches in it that bad. It you have it turned .010" and it cleans up? then great.

I thought I found a good machine shop I had them check the crankshaft afterwards they polished it and said it was good to go. And I doubt I damaged it during transport.

I also decided to examine the camshaft to see if it could be re-used and it looks like one of the lobes has a bad flat spot.

If I'm seeing what I think I'm seeing (4th lobe down)?? that cam is junk.

Yep it's flat as a board.

H O-Lee Chit Batman! That's horrendous.

I'm between a WTF and LOL...

Thanks guys. Got the crankshaft torqued and thrush seated. What's the cheapest way to measure??

Also I was looking at the crank and the machine shop said it was fine but I noticed a hair line scratch or crack

That will do two things: seep oil from the get go and wear out the seal prematurely. You could try some emery cloth to see if you can get it to clean up but based on that cam, I wouldn’t trust a thing that shop said.

I will try the emery cloth and see if that helps. Im thinking this wont cause much damage. When I rub my finger over it I can barely feel the scratches.

Here is a little more info. Some are saying emery cloth is still too coarse but the consensus seems to be 400+ grit wet/dry sandpaper with mineral spirits or ATF wrapped around the journal will do the trick: https://www.thirdgen.org/forums/tech-general-engine/132755-emery-cloth-polishing-crankshaft.html

Pay to have a GOOD machine shop polish the crank. They should start at the bad area(s) ti see if it polishes out.

The machine shop I used cleaned it up pretty good compared to how it looked when I dropped it off when I looked at it when I picked it up I didnt notice it. Hopefully it cleans up when I get some time this weekend to work on it. Im trying to keep this rebuild at a minimum I would hate to get another crankshaft then have to get the rotating assembly balanced
