I just bought a 1966 F250 v8 352 it is in fair shape im the third owner
the engine runs but i waned to see how good it was so i did a compression test on cyl 1.4.8 4 was the best there is oil on the plugs so im thinking the rings are stuck. Can i free them with out taking it apart? i have heard some thoughts on this involving poring Autorx in cyl to free the rings is this posible?
this is the first for me on forums..
any thoughts?
thanks macgyver55

 

Welcome to FTE! There are some pretty sharp Ford guys here.
I would start with a complete tune up involving the entire ignition and carberator and see how well it can run. If you don't already know, your block style is known as an FE.
Here is a link to that forum.

I would pop a valve cover off and take a look.

Oil on the plugs is mostly likely bad rings or bad valve stem seals.

 

I hear you i paid 4000 if i sell ill be lucky to get 4500.
