Been working thru process of elimination, basically going thru the list of possible causes from least severe to most severe.
At this point I've narrowed it down to bottom end. If I had to wager, I'd bet on upside-down 2nd rings, but this weekend I'll disassemble and find out for sure.
Ding ding ding. Precisely what someone did, no oil support rails on the pistons. It also had really bad ring gaps throughout.
But another issue revealed in the bottom end, it was gonna chew bearings and chuck a rod anyway. Looks like clearances were set up poorly as well.
So I dont know if ill be fixing it or not at this point.
Sounds like what i'm going to have to do later this year as well. I expect to find some kind of ring issue. If I were you i'd fix it, but really take your time with it. Remeasure/reset main and rod bearing clearances. Perhaps even have the block rehoned if it keeps you within the proper ptw. The bottom line is, you've come too far to stop now and now you actually know what you have to do to fix it.
I had a pro assemble the bottom rotating assembly for me and got it back yesterday. I went ahead and put the pan on to cover the bottom, then installed the L19's and the head..
There are two indispensable facts that this forum has taught me:
1. There are still people alive today who think the world is flat.
2. There are no such thing as pro's. Just regular people who have had a lot of practice and still make mistakes.

Yeah really the only difference between an amateur and professional is a paycheck. I was a professional race car driver for a while, but in no danger of winning the Baja 1000.
Not alot of updates here. I can say that rods & pistons were ordered and engine block dropped at the machine shop. Gonna be Eagle crank 100mm and 2.3 86mm Wiseco HD, Wiseco Boostline rods.
But I'm not very interested in that, been too busy with the new toy. Bought this 2017 Silverado...
Also picked up a SAE pushlock to 6an fitting for the return line on the hanger and I'm going to turn the unused 5/16 evap hardline into a return line. Then I will just have a couple short AN hoses to connect them.
I do have a question on opinions though. Should I do the ends with a compression fitting like this?
