Weird compression after rebuild

[EndZee]

Hello, after engine rebuild(new cylinder liners and piston rings, arp headstuds, metal cometic tripple layer gasket, all new main/rod bearings) and roughly 100km made I did measure compression and it’s (1-6) - 80, 60, 90, 120, 110, 135. It’s rb25det series 1 - hydraulic lifters. Measured on cold engine. Didn’t check on hot due to overall car problems such as broken 3rd gear, idle issues, misfire etc. I did smoke test only on 2nd and 5th cylinder bcs soldering iron used with this method broke itself. So after setting cams to side - side 90 left/right angle I can see smoke coming off from intake manifold and turbo exhaust flange. 5th didn’t notice any smoke. Shop did head, valve etc job but I assemble it by myself. So I thinking about lifters. I don’t remember if they were soft or not it was long time ago. In my opinion I didn’t bleed them and they can be opened more than they should be. Can it be more likely possible? Or timing can be off by 1 teeth and can cause such weird compression? But if timing would be out wouldn’t it be like such big difference across all cylinders? Please help I’m so sad it happened.

I can also smell fuel in oil if that helps.

More likely you didn't bed the rings in correctly and have glazed the bores. Running with misfires on a fresh build is somewhat of a no-no.

Surely no-one "smoke tests" the combustion chamber? That's what a leakdown test is for. Smoke testing is, um, a bit of a wank at best, and only really useful for external pipework.

Yeah. air pressure leakdown test is where I would be headed next here, using one's ears to determine whether it's the valves or bores/rings leaking...
