A couple of things that you may want to consider prior to doing a compression check on this engine since it has been sitting for a while.
1. Remove the DME relay. If there is any gas still left in it you want to at least drain and replace it before you attempt to start it.
2. Don't start it until you've at least inspected the belts.
3. Check the oil level. It may or may not show water contamination. This does not necessarily mean the oil cooler seals are gone, it could be from condensation.
4. Pull all 4 spark plugs. Spray a liberal amount of WD40 in each cylinder. Try to soak the high side (9 o'clock position) of the cylinders the best you can. A piece of 18"-24" brass tubing the size of the plastic tube that comes with the WD40 so it can be bent works good.(Hobby shops)
5. Using the crank bolt and a 24MM socket gently rock the engine thru a few degrees of rotation to free the rings up. This will also be your test to see if there is any interference with the valves.
6. Pull the engine thru (360 degrees) by hand at least half a dozen times to let the WD40 lube the cylinders. If you've got a buddy with you, give him a shot at it too The more the better and your compression check numbers will be more accurate. The idea here is not to score the cylinder walls or worse, break a ring.
Other than not forgetting to block the throttle plate (butterfly) open that's about all I can think of off hand. I hope this works out for you and the world will have another recovered 944...Dave
