With all the spark plugs removed the engine can rotate much easier and with less resistance since there is not any combustion being created in the clyinder thus less pressure on the rod bearings.
By all means check the camshaft sensor and syncronizer, but I recommend getting a new sensor and syncronizer if replacing ( with a new syncronizer you should get a alignment tool with it), these parts used could be faulty also and salvage yards will not give a warranty on some thing like that, at least not where I am at. Yes a new part can be faulty, you never know either way.

Yeah, awesome ,thank you. Okay, the answer you gave solves a lot, I will definitely do that tomorrow, get a new valve seal tonite, yank it tomorrow.
The reason I wanted to go used, too, is because I need to replace the driver's lock actuator, passanger one too, and the window lifting thing, plus I did not want to spend another wad of money I am short on anyway getting two sensors totalling $130, since I simply do not know what is wrong. It makes a popping sound, other people have experienced it, so I am totally clueless as to why no one else has solved it. All the recent posts seem to point to something the same or near mine, too. I would think with that kind of majority, something would happen to solve it.
I understand now what you mean. According to my friend ,the valves open and close, and the rings and etc. all cause compression, so if it passed the test, they were good. That is obviously somewhat of a stretch of the truth.
I will get the gasket tonight or tomorrow, and yank it tomorrow when I replace both sensors, if I can get a ride.
Thank you for explaining it! He, my friend told me, if it meets that, it's fine. I have wondered if he was stringing me along, or not. Now I know he could just be not telling me everything for whatever reason.
