Re: Cylinder Clearance
not yet but it's obviously been bored by the PO.
Yea but when was that? Last time it was rebuilt? Unless its been freshly mic'd and bored or honed
since its been taken apart, then it needs to go to the machine shop. It will need at least honed. You could do the honing but you'd be better off your first time using the machine shops services.
Did you mic the bores like I said except to check for taper? Thats how you determine if the bores need bored. I forget the exact spec but I think its if the taper is more than 3 thou it needs bored over.
Also what pistons are you using? Speed Pro pistons with the coated skirt like I have adds a thou to the pistons size. They come with instructions on how to take that into account when measuring.
But we need more info on this.
Where did you get this block? Was it in service and now your rebuilding it? If the engine was not running what happened to it? Knocking?
I dont know what all you know about all this but usually a rebuild entails having the block bored or honed, crank polished or cut, mains checked/aligned, heads refurbished (valve job etc), block checked for cracks and cleaned.
Theres alot of things that NEED done if you want even a chance of being successful.
Maybe you should start off by telling us what you have/haven't done.
