Hey guys. I have a 02 rancher that just started smoking really bad. The sad part is I just did a top end rebuild about 4 months ago. New cylinder, rings, piston, valves, valve guides, gaskets… the only thing is I didn’t check the ring gaps. It all came as a kit so I figured it should be good.

About 15 hours after the rebuild my wife accidentally drove it into the lake. No water in the intake, but it got in through the exhaust. Pulled plug, shot the water out, got home and changed the oil. No water there. Ran great for another 20-30 hours and then just started smoking.

Did a dry compression test and got 0… wet got 130, 30, then 0 on the last one.

Going to pull the top end back off and have the bore checked and maybe a slight overbore.

My question is should I put maybe a hi compression piston in while I have it apart? Any other upgrade I should do?
