I have a question that relates to measuring for oil clearance for main and rod bearings. I understand you are supposed to torque them to spec to measure for clearance on both rods and mains. However I thought main bolts as well as rod bolts were only supposed to be torqued one time ? Doesn't this stretch the bolts and when retorquing the bolt wouldn't it be inaccurate ? Or will the bolts go back to size ? How does this work when torquing using rod bolt stretch ?

Only TTY bolts are to be used onetime. Most Hondas do not utilize TTY bolts. Not sure about ARP.

 

So they should return to their original size when untorqued correct ?

 

yes. I do belive that is how they are designed. Unless stated otherwise per the manufaturers.
