Okay so the timing on my 3.1 was way off, so I go buy a light and I start setting up the motor to TDC and I get it all set and I start the car to set the actual timing and as I'm doing it the motor starts running crapy so I figured I had it to restarted, then it dies, I go to start it back up and nothing, just clicks from the battery, so I grab my ratchet and try to turn the motor by hand, and can't even budge it, I check the oil and its full, what would cause this?

You cant turn the crank at all???

Check the plugs and look for bad signs there first, since thats simple to do.

Whats the history on the engine?

curtalert89

Nope, won't even budge, not even by turning it manually, and the plugs are all good, and the motor only has 200,xxx

pull the plugs out and try to rotate the engine. sounds like the timing is to advanced of battery is low bad starter or battery connection. You shouldn't be trying to rotate he engine with the crank bolt.

Uhhh, why not?

The battery is at full charge, it was running while I was timing it and the motor jerked around and just stopped, and I'll pull the plugs in the morning and see if it changes anything, and why shouldn't I be turning it at the crank by hand?

the damper bolt it intended to retain the balancer if your not use a bump starter of flywheel turner and use the bolt you can strip the threads on the crank or bolt.

witht he plugs out its not going to strip the crank bolt , even with the plugs in if u use a good socket thats the correct size it wont strip out

Ive used that crank bolt xxx many times and never a issue. Its not like we have 10:1 compression...

Will NEVER happen.

The only thing that could strip the threads of the damper crank bolt, is using the bolt to pull the damper onto the crank during installation, due to a reduced amount of engagement of the thread thread, during installation. When the damper is installed, there is a large amount of thread engagement.

You may have spun a main or rod just a idea

Not locked up, was messing with it and turned the key, and it somewhat started up. I guess when I was messing with the timing I set it way retarded and it built up a lot of compression. Dodged a bullet on that.

If the timing is too retarded or advanced, it does not have anything to do with the compression. The valves are still going to let out the air mixture regardless if its ignited correctly or not.

Well idk what happened with it then, ha. But it turns over now.

Timing chain jam? It could have a streched chain with 200,000+ miles right?
