I have a 2008 rancher 4×4 fm w/o power sleeting and have a bad engine . The cylinder needs to be bored out for a third time . And when we bored it out the second time and replaced the piston and ring cleaned out the bottom had , replaced the crank . But it was knocking and my mechanic said that the transmission shaft was bent . So now I am stuck between options : 1 … Bore out the cylinder for a third time/replace piston and rings then deal with transmission rod at the same time … Or …. 2… Buy a used engine off eBay and put it in … Sense I have to get a new engine can I buy a newer year engine like a 2012 4×4 engine w/o power steering …thanks
