Good morning Team Slotus!
I spent some quality time in the shop over the weekend, when not accompanying TWWTFM's daughter and our grandson to the ER for what turned out to be an ear infection/strep throat. Story for another forum...
I got the rear suspension re-assembled with the new br@ckets and bushings and such. It goes Bouncy-Bouncy much better now. Further testing will be required.
Then on to the real fun part... I pulled the motor and began the teardown. Got the big piece out of the frame on onto the motor stand, began some cleanup and gasket scraping, then flipped it over and looked at the rods, crank and pistons. Earl came by and assisted with the inspection. Nothing waved any red flags at us, but more teardown/inspection is needed. I did pull the #1 rod/piston out of the block (OK, Earl did most of that, but he ain't here, I'm taking credit...)
Here's the weird part... Y'all knew there was gonna be a weird part, right? When I did the leakdown test correctly that second time around, most of the obviously leaks were audible at one valve or another, usually the exhaust valve. However, the #1 cylinder was one of the ones that appeared to be leaking air around the piston itself and blowing it into the crankcase. We assumed "burnt piston" at the time. OK, yesterday, we pulled #1 and it ain't burnt. Rings look good, no "erosion" around the edges of the piston, no real tell-tales of any defect at all, except a small mark on top where something (piece of a metal?) hit it. So, why did it appear to be leaking into the crankcase instead of around a valve? Anybody???

Here's a picture of the #1 piston, taken to record that part number, but you can see the "ding" in the surface. Doesn't show the nice, clean edge around the perimeter, but take my word for it. Oh... No??? OK, FINE, I'll take another picture later...
So, what do y'all think? Was it just at the bottom of the stroke and the rings weren't sealing due when I tested it? (It hadn't run in quite a while.) Or was it Aliens? Or Sharpies? Or Alien Sharpies?
Peace, Love and Aliens-
JDK
