How Difficult is it to change piston rings?

 

8 out of 10.. Very time consuming though.

 

depends on your experience on cars. like for me im puting pistons and rings on a b18b hopefully this weekend and itl probably take me about 3-4 hrs. and i have a compressor. it will take probably about 6-7 with out one. so its very time consuming but if you take your time and the right tools its not that hard
