Hi
My 4runner has had a knock in it and I'm in the process of tearing it down to the heads, and if I have to, to the block. I was wondering
whether anyone knows whether its worth boring over a little and what the largest size piston you can get without having to adjust the
valves too much. I've also found a complete rebuild kit for $230 including oversized pistons, and the gaskets I'll be needing anyway.
