Default Re: A few questions on a 8BA

Stuck valves have been known to break cams and cam followers if enough pressure is applied. I got a truck motor once where a farmer had been dragging the truck with a tractor to break it free. It broke alright but it didn't break free. I had a hell of a time getting that one apart. Busted cam and a follower with a valve stem sticking in it plus all the usual crusty pistons and other bad parts finally came out but not without a fight.

A good penetrant like the double A variety (Acetone and ATF 1:1 mix) will work wonders over time. Pouring on some of the modern rust removal products like Evaporust won't hurt on the real crusty stuff if your set up to soak it.
