In taking it apart to do the vac test I pulled the flywheel. To my surprise there was a lot of caked gunk back there, something I couldn't see when I peeped behind with the flywheel on.
I did the vac test and it was holding at about 45...don't know parameters...in. of mercury or something.
Then I got the bright idea to do a pressure test. But instead of using my brake vac device I got the leak tester. So I sit pressure at 40 and though i felt a small leak so I went to 50.
This got in before the picture of glasses
I decided to put on NEW gaskets and a NEW seal on flywheel side(other side already done) and give her a try. I checked the iso plate for flatness. But it was changed out anyway.
Just as I was lowering my face toward the air leak the crankshaft seal blew out and hit my grasses
Got to order seal....Happy New Year
