2007 chevy 6.0 engine. I rebuilt the engine, everything great, got new crankshaft, now having a problem with the engine locking up

Did you maintain the clearance between the crank bearings and the crankshaft? Same goes for the rod bearings. Is the oil pressure too high? Sounds like there are tight bearings.

My 2002 envoy engine locked up while it was parked????

It can happen. Usually caused from the oil being low or going low to many times. When it cools down, the bearing will seize on the crank shaft. Also seen the A/C compressor lock up and keep the engine from turning. Both can be checked.

Why is my engine light on and the gear idicator flashing?

The shift solenoid valve DSL is turned "ON" and "OFF" by signals from the Engine Control Module (ECM) in order to control the hydraulic pressure operation, the lock-up relay valve, which then the controls operation of the lock-up clutch.
Torque converter lock-up is controlled by the ECM based on engine rpm, engine load, engine temperature, vehicle speed, transmission temperature, and shift range selection. The ECM determines the lock-up status of the torque converter by comparing the engine rpm (NE) to the input turbine rpm (NT). The ECM calculates the actual transmission gear by comparing input turbine rpm (NT) to counter gear rpm (NC). When conditions are appropriate, the ECM requests "lock-up" by applying control voltage to shift solenoid DSL. When the DSL is opened, solenoid DSL applies pressure to the lock-up relay valve and locks the torque converter clutch. If the ECM detects an open or short in the DSL solenoid circuit, the ECM interprets this as a fault in the DSL solenoid or circuit. The ECM will turn on the MIL and store the DTC.

If your engine locks, is there anything you can do or would it be better to get rid of it?

I would pull the engine and strip it down as not all locked engines are un- repairable ( depending on the reasons for the lock up). Next best bet is to get a good unit from a reputable wrecker or a reconditioned exchange unit from an engine rebuilder shop

Car engine locked up

Do you mean the timing belt, or the serpentine belt ?
The serpentine belt could lock up the engine if one of the pulleys was froze. Sometimes the alternator or power steering pump will lock up.
But if the belt is off the engine it would have no effect.

Will a compression test will let me know if my engine is locked or seized

If you believe the engine is locked you should put a wrench or socket on the crankshaft bolt and see if you can turn it (turn it clockwise)if it turns your engine it not locked or seized. to do a compression test the engine must spin with the starter. if an engine is locked or siezed a compression test is impossable.If this was helpful please leave good feedback

Engine as locked how do i unlock it

If the pull will not move it and with it off still locked the engine needs to be looked at as it may have seized.

Dealership said that i over flowed the coolant and it spilled over and and it leaked onto the lower intake & locked up the engine, it is still locked up after replacing the lower intake. Now they are...

Overfilling will not lock-up the engine. There is probably another cause for the engine to be locked-up. A starter can be locked against the flywheel. The engine oil can be contaminated or broken down causing bearing failure. Excessive fuel in cylinders can lock an engine. Hope this helps :)

1993 lumina engine locked up

the problem may have been as simple as a locked up alternator. Did you check too see if it was changed? The alternator will simulate a locked up engine. If an engine locks up you wont be able to get it running. The crank welds itself to the bearings or the rod locks up tigh. I suspect your engine was fine from the start.
