[QUOTE="jony51999, post: 15783480, member: 155011"] Hey Cody, from what I've learned with regards to rebuilding these motors even the hone job is pretty involved to do it right. To do it properly you really need to use a torque plate and even head gasket that you plan to run (the old ones should suffice and you can use the old tty head bolts for that as well since you cannot reuse them when you do your final reassembly. Also remember that these engines use a 4032 high silicon forged piston so the piston to bore clearance is much tighter (typically around .001) than a typical 2618 forged piston. I'm planning on upgrading to 2618 pistons when I rebuild mine which will give me a stronger piston that can handle more abuse (albeit at the cost of being a little noisey when cold as the piston drops out of the bore at bdc which means the largest diameter portion of the piston is out of the bore so you get a bit of piston slap noise until it's fully warmed and expanded to operating size). That said another benefit of using the 2618 alloy is that you will still be able to use a std bore piston without being concerned that your piston to bore clearance will be too big due to the material removed when honing as the 2618 needs around .003-.0035 ptb. That of course is assuming there is no serious scoring that would necessitate a bore and oversized piston to fix it. Sent from my iPhone using Tapatalk [/QUOTE]
