Seized motor
Best way to unseize a motor?
|
???
Remove spark plugs so no compression in any cylinder See if crank will turn with starter motor, if not then see if you can turn it in reverse direction with wrench on crank, if so could be broken/stuck open valve or broken connecting rod possibly if it turns one way then stops then turns the other way and stops If not pull out the engine for rebuild, either main bearing has "spun" so crank is welded to the block, or piston and rings are stuck in one or more cylinders. This is assuming the transmission is not the issue and holding crank shaft in one position |

Should I try to keep turning or new motor? |
Timing chain, so I assume its a 2001 - 2011 2.3l Duratec engine?
Pull valve cover gasket first |
We did that. It is a 02 2.3l. Still so tight. Starting to think it is a rod.
