Quick update before I hit the road later this am....
Got OL YELLR loaded up last night and celebrated with pizza and some Yuppie Brew. Two days ago, I notice some spots under it, yesterday a third and bigger spot under it - (been sitting still for weeks - such a good boy, stay). (One pic from Thursday, one Friday)
Thursday (two spots a) front diff, b) the back one I see is at the flywheel/bell housing).
Friday - WTF
Going to do one more thing in KC, which basically take a carb we know is good (working on friend's 40) and put it on and see. All it will do IMO is verify the engine rebuild was/is not right for reasons not understood yet. (was/is a great learning lesson - know way more about engines and carb vs getting a rig that just worked).
A couple weeks ago, I took to shop for some engine tests... they did compression and leak-down. Compression was not wet tested - engine was warm. Three cylinders were at 100, three at 115 (tested 3x and did average per cylinder).
Leak-down... (quoting notes from shop) "Removed valve cover and loosened all rockers to ensure all valves were seated, rechecked cylinder leakage on Cyl 1 and Cyl 6 at TDC and found Cyl 1 had 39% leakage and Cyl 6 had 29%. Stoped test. Installed smoke machine to Cyl 1 through leakage test hose and found smoke coming from crankcase. Leakage is past piston rings. Engine will need to be torn down for further diagnosis."
I did a wet test after since they didn't - helped anywhere from 0 to 10 psi over the cylinders. I kept it relative to my tester - tested dry, then wet etc.
Anymore of that Yuppie Brew?
Being a noob, part of me had been thinking well maybe the rings haven't set yet from the rebuild and why the big leakage - and having a carb without the secondary is not helping the engine break in - why I've been hell bent on the two carbs I have. And maybe the camshaft is off by a tooth. Hard to explain the low compression right now. Been in contact with the machine shop too, just in case.
So - given one leak is from the front pumpkin, I'm going to entertain the idea off pulling several more parts off and go over them so I know the condition of them vs guess what how the PO's drove while the engine is getting more TLC. Decided to pull out my favorite Ron Swanson Quote... "Don't half-ass it, whole-ass it."
Silver lining is I will get to spend more time in the hot tub with Yuppie Brew. For those not from the rural parts of prairie, that is a stock tank next to a camp fire.
Cheers..
