A neighbor of mine just bought an '00 GT. He noticed I had a Mustang, so he came over to ask my advice on a problem.
He said he had noticed some slight clicking noises from the engine, and as most 4.6's go, I didn't think much of it but didnt have a chance to check it out. Today he came over and I had a chance to look at it.
The engine itself seems to be seized completely. When you try to start it, you hear a clunk from the starter and nothing else. I tried to turn the crankshaft over by breaker bar and it will not budge. He had mentioned that the intake was replaced a few weeks earlier, but never mentioned why. My best guess is that he had an intake leak, and it caused antifreeze to seep into a cylinder and hydrolock it.
He had stated that he was driving it and it just stopped suddently. He said he tried to start it again while it was rolling by letting the clutch out but nothing would happen. If something did indeed stop the engine from spinning, it would have caused the rear tires to lock up, correct? He never mentioned anything about that so that's what makes me think it may not be something physically wrong (valvetrain/crank/rod..etc).
Any suggestions on what I can try? I told him to try pulling the sparkplugs and see if there's anything on them or if maybe he can try cranking it after that. Other then that, it seems like there's nothing more you can do other then pulling the oil pan or even the valve covers (i would think you'd still get a few degrees of turn on the crankshaft due to the links in the timing chain if it were valvetrain related)
Thanks guys... im a 5.0 guy myself, but i'd love to see him get his car running again so thats why im asking here for mod motor advice.

Even if it was hydrolocked you should still be able to turn the crank, it just probably wont fire up. Good luck, let us know if you find out whats up.
