I purchased an 82 GSL in Oklahoma City this last Monday. towed it home and started going through it. It had been setting in the back yard for 15 years. Yes there is some body cancer, and the interior is trash, but I was hoping that the power train was intact. Well I pulled the plugs to shoot MMO into it and found one of them was rusty! When I was finally able to get the motor to turn the MMO running out of the rear chamber was rusty!! Yesterday I pulled the radiator to flush it out and check for leaks. I decided to flush out the block as well so I hooked the hose up to the upper radiator hose and water started flowing out of the lower one. It also started running out of the bottom of the engine in the rear!!!
Do these motors have freeze plugs, or is my problem much worse than that? Is it worth taking apart and looking at what is there? Does anyone think that there is a remotor chance that it can be rebuilt?
Thanks for your input,
Darrell Button

 

Any rust inside the combustion chambers (especially after 15 years!) will pretty much mean you're going to be replacing just about everything. Housings, irons, rotors, etc...
