I am taking apart a VERY stuck BN engine.
Goal is to save the block to replace the cracked one on my running BN.
I have this engine on an engine stand where the cylinders have been
soaking in ATF/Acetone mix for several months.
Took the head and oil pan off today. Cylinders are in really rough shape.
Rust on the sides of the cylinder walls over 1/8 inch thick.
Cylinders were about 3 inches full of ATF still. Not one drop has
managed to leak by the pistons/rings into the oil pan.
I loosened the main caps and was going to remove the oil pump
but I can't get it to budge. I've got the two through the block
bolts out, but it won't wiggle away from the block or turn.
I tried taping it with a hammer, etc. No movement at all.
Now that I have the bottom open, it's soaking upside down in
penetrating oil.
Any tips on getting the pump out without breaking it?
Or other tips in general on an engine this stuck?
It's a donor, but I can't see destroying it.
