Engine Seized...Help!!!

[pro0846]

I just bought a 1970 Opel gt. my plan is to restore it, the body is in great shape, electonics work great, everything is perfect... except the engine is stuck from sitting in a barn for so long...... any ideas of how to unseize the engine?

One thing to try, before going onto harsher methods, is to grab a 19mm wrench, or a 19mm socket with a pull handle, and see if the motor will turn over by hand. Remove the spark plugs first, and if it's a manual trans, put it in neutral, or if it's an auto, just pull it out of park, to make it easier.

I would disconnect the fan belt first. I've seen what appears to be a seized engine turn out to be a seized water pump. If after removing the belt the engine is still frozen, you can remove the plugs and squirt some mystery oil or other light penetrating oil into the chambers. Trying to get a 19mm wrench on the crank with the radiator,shroud and fan still in place is very difficult. So instead, if you have a manual transmission, put it in 2nd gear and rock the car to see if the engine will rotate. That's if the brakes haven't seized.

Jerry,

Can always employ a good Opel mechanic down here in Lake Elsinore!!!

The lubricant of choice here is PB Blaster works great at getting rusted parts "broken"

Jerry's suggestion on the water pump makes sense, so I'd try that one first. Not working I'd move on to removing the plugs as others have suggested and squirt you're favorite rust penetrate in the spark plug holes and rock the car in gear as I believe it will have more leverage than a pull handle and socket on the crank. You probably won't mess up the crank bolt but... If it doesn't break loose close the hood and try it again another day(s). Patience!

You might want to get a look inside and then make a choice how far you want to go. I have a car (not and Opel) that sat inside a barn that was climate controlled for over 20years. The engine was locked up tight. I pulled the water pump and it looked like lava in there. I decided a rebuild was the only way to go.

Just something to think about.
