Default '03 PT not starting after timing belt replacement

I just bought this PT from a friend who gave up on attempting to repair it. The previous owner ran the car out of coolant (leak in radiator) which effectively blew the head gasket. He had already pulled the head, inspected for warping, reseated all of the valves, then re-installed with new head bolts and gasket. Right now, only 2 of the 4 pistons have normal compression. The middle two cylinders have around 50 lbs or so of pressure. It's possible it could have a cracked block or head (need to magnaflux for cracks).

Before I assume the worst, I wanted to confirm that he correctly timed the engine before I go any further. Thoughts?

I'm pretty sure the only way to find out if the timing is correct is to put it apart and check the timing marks. I'd be more worried about the loss of compression in two of the cylinders.

Look at the top pulleys, the marks don't need to be exact pulley on the left needs to be down half of tooth

I agree the only way to know for sure is to go back through and check out the timing setup on the engine. I plan on checking it all out on Saturday. In the meantime, I'm scouring this forum checking for things that could be causing the loss of compression in the middle cylinders (not being that familiar with the 2.4 DOC engine).

I realize crankshaft TDC is critical, and could most definitely cause low compression since you would have a situation where the intake or exhaust valve is open when it should be closed. I'm ruling out an issue with the pistons, rings, and cylinder walls since those were visually inspected at the time the head was put back on and appeared to be in great shape.

I guess I'm just looking for suggestions on what might be going on here.

Could the compression loss occur from having the timing off a couple cog's? Or would it have to be off quite a ways or in combination with the Crank TDC?

Any Takers?

Thanks
