Dead engine: Rebuild, replace, or wrong diagnosis?

[svxcentric]

OK, the engine in my 97 SVX seems to have given out (197K miles). Friday afternoon I was at a traffic light and it burbled and cut off. Couldn't restart it. It would crank but not fire up. It wouldn't even threaten to fire up. Just crank. No codes. Had me thinking it was a number of things as I was towed to a local shop. Here's the list of tests that were done:

1, No codes on the computer
2. Fuel pressure..OK
3. Pulses to the fuel injectors...OK
4. Spark..OK
5. Air/MAF sensor OK
6. Covers pulled and timing checked...OK

At this point we were thinking maybe Crank or Cam sensor..but there were no codes so it would have to go on the computer to check the waves. Before doing that the mechanic wanted to do a compression test on all cylinders. What he found was that the compression was fine in the driver side bank but there was no compression at all in all the passenger side cylinders.

What's really strange is that it was running fine just before this happened. I didn't stress the engine at all. I drive sensibly for the most part.

OK my question to the group is this: Do you think this is a cracked head or blown gasket? Do you think the best way to go is an engine swap or a rebuild. If it's the former does anyone have a lead on a low miles EG33 for sale? BTW, I'm in New Jersey.

Thanks everyone.

Check the cam timing again.

cracked head: NO, that just is not a thing that happens.
something else with timing.
your engine is going to be fine.
