It has a combustion chamber! Just very small, and completely tucked up inside the head.
Actually, the compression ratio is high enough that even a modest amount of oil could be causing the PSi readings to go up. even if it didn't really improve the ring sealing (much).
I'm no diesel mechanic, though, I have no idea how far 180 psi is from what it needs to be.
Is it possible you just have dead glow plugs? That would be a more likely sudden no-start vs. a rapid loss of compression across all cylinders. Do a risitance test across each one, make sure they're getting 12V+ when the key is initially turned on.
