98 crank spec. And valve help
 

I have a 1998 LE 4 cylinder and am replacing the rod bearings. What is the correct size of the crank supposed to be so I can determine the proper size replacement bearings. I don't know if I should go over sized or not.

I also have a valve tick and want to know if that is adjustable. I had the timing belt replaced last year so I don't think that is an issue.
