I bought a 04 RX1 with a locked up motor, It looks like someone hit a stump & took out the front heat exchanger, This sled sat for over a year with no oil in it ( was told they started to work on it but gave up??? ) no sign on leaking oil, engine look Ok - no holes? , pulled plugs -black -- cylinders look OK through plug hole, no coolant in system, looks like it drained out from front heat exchanger.
Tried to turn primary clockwise, would not move.
turned 1 turn counter clockwise, sounded like the reduction gear was moving ??? Then turned back 1 turn till it was & lock up again, I did sray PB blaster in cylinder to lube first,
It may be junk, maybe overheated, or lock from sitting
Where do you start,
What happens if you lose all coolant / any auto kill protection

There is no overheat autokill when the thing is running at speed... it will shut off if it overheats at idle.
In the very least, remove the head and inspect the top end. If you're lucky, you have a stuck valve from sitting and the engine is alright. I VERY strongly doubt that the bottom end has any MAJOR problems, the pistons/rings/cylinders could be damaged from overheating, it is also possible for overheating to cause it to throw a rod. From sitting without oil, you could have bearing problems in the bottom end, but that *probably* isn't the case unless the thing was stored in a very wet location.
I would take the head off and inspect for physical damage. If there is obvious evidence of a stuck valve and the pistons and cylinders look OK, then try rotating it by hand and see if it will turn over normally (hold onto the timing chain and keep track of how far you rotate when you do this and turn back to same position).
If you're going over the engine to this degree, it is probably also a good opportunity to replace the RINGS. Overheating DOES hurt rings, so it makes sense to do this either way. You now have the opportunity to disassemble and inspect the bottom end.
If the thing has an obviously thrown rod, don't bother trying to repair it... part it out and/or use it for your own parts.
