I was working on the last part of my engine which was to install my blockguard. I filed it down to size. I had to tap it in with a hammer because it was a very tight fit. Well i figured out that my ring gap was incorrect so I went to take everything back apart to replace the rings. Well on the cylinder that had a tight fit because of the blockguard i noticed the piston was very hard to get out. Well when i went to install it again it wouldnt fit. Then I realized that the blockguard bent my cylinder wall. Even if I take the blockguard out the cylinder wall will still be bent. I cant even budge the blockguard so I have no clue how to get it out. Is this engine totally ruined. Any ideas?? Im thinking even if I manage to get the piston in there everything is going to crack to hell because its all pressed together.

 

can anyone help me with this? only thing I can think of is screw into the block guard and remove it. Then take the block back to the machine shop and rehone that cylinder. The other 3 seem to be ok because the pistons installed with ease. My only worry now is the integrity of the cylinder walls after being bent.

 

aren't you supposed to have those put in by a machine shop to make sure they go in perfectly level?
