was planning on first start today; however, got everything ready to go, went to put in coolant and there are leaks.
reservoir has a big crack in it. upper rad hose has small leak.
tempted to junk yard them but also dont wanna risk another junk part, but jesus the radiator hoses are expensive!

Junk yard them for the satisfaction of engine start and a good run; then put them on the 'things to do' list and hope they don't pop in the meantime.  |

an welds brazed over. Side note brazing is weird.
Kind of fortunate, I had to tear quite a bit out(turbo, uppipes, downpipe) and found a couple things that might have been issue down the road.
- oil distro block had two washers on one side of each banjo, looks like the old washer "stuck" to the block and i did not notice during assembly. Probably would not have been an issue but resolved anyway.
- waste gate v-band into down pipe was not seated properly, would have leaked for sure, but just been noisy/smelly.
gonna go to junk yard tomorrow to get overflow tank. I ordered one online but wont get here until Friday and I'm wanting to see if this thing will fire up!

well it started, but its running like a tractor.
It's either missing or timing is off and valves are properly smashed.

consistently starts now, but only running on 4 cylinders.
2 and 6 do nothing but missfire.

well leak down was fine. All cylinders between 8-10%, granted that's with a harbor fraught tester, but even still leads me to believe as of now the valve train and rings are sealing properly.
i put in new plugs too the ones that were in there were fouled to all hell. Will test it once i warm up enough to go put the charge piping back in.

Cool so still having misfires, but stethoscope'ed the injectors and 2 and 6 are not making much noise if at all. Also new code showed up saying barometric and map sensors have implausible signals which I have read means 02 sensors shorted out and ECU is fried. Previous owner had main loom stuck between up pipe and down pipe so that is highly plausible.
New direction is source ecu. fingers crossed.
