Ok...I've gotten ready to put back the 87GL engine that I have rebuilt.

Notice today that the Bentley (OUR BIBLE...) says, "alway replace" on
the connecting rod nuts.

Does everybody do this? Are these nuts a standard size, type?
I don't notice anything special about...ie... as in the seals in the oil
pump nuts (which I am replacing). What's up with these and will I live
to regret it if I don't replace them????

Thanks in advance folks!
