Question about Vehicle Parts & Accessories
In your instance it's really a toss up. Do you trust that the engine was rebuilt properly? Did you check the oil real close, and especially pull the drain plug and check the oil that comes out. If it's got metal flakes or ever worse, shavings, they might have only gotten 20mi. before it ceased up. It could have stuck rings. But a V8 is hard to turn over by hand even when it's not ceased. If you think it was done right and want to break it free, I'd spray WD-40 or better yet this stuff called Blaster 50 that seems like a gimmick but it's sold in most auto parts stores. IMHO it works better than WD-40. Pull the spark plugs, spray a bunch in each cylinder. Then I'd take the air hose off my compressor and spray each hole, then repeat. Yeah, you might get a face full of the stuff, but it's going to force the spray around where you can't get to with just the spray can and force it down in the rings. You should know that more than likely there's going to be damage to the cylinder walls if the rings have rusted themselves to the walls. And the rings will most likely be frozen in the ring lands. This causes all kinds of probs like low compression, smoking, and high oil usage and fouling plugs. Once you sprayed the cyl's good, pull the flywheel cover off and get the proper flywheel wrench(it looks like a bar with a hook on it, it's made to grab the flywheel by grabbing the ring gear teeth) and see if you can break the rings free. Might take a while. And if it never comes free it probably means the reason the engine froze up was because the main and rod bearings either were not installed properly or they didn't get oil. Be prepared to find you need a whole new engine. Good luck.
