Need to know if they can be swaped out? We have have a b18 and its missing a main cap.

 

I would. . . on your car, but definately not mine. Good luck finding it!

 

main caps are not even the same from block to block. It also depends on what b18 motor your talking about. A gsr is going to have a girdle involved with the mains as well.

 

ur gonna have to get it line bored i believe. i ran into this same problem...when i thought i lost my caps. you need to get a perfectly straight hole ....it may be straight usin other caps but is the angle true?
it hard to type what im sayn but it makes sense when i look...
