whats up i got a b18 block with b16 pistons all at 40 with a b16 head with crower springs and retainers noyhing is ported in th engine. now the promblem is that i recently pulled off my valve cover and saw that on one of my gsr cams had a crack on it. what are possible promblems that could happen from a cracked cam? cus right now my motor smokes alot but at random times. and i also want to know what would be the best cam setup to put in? i heard i shouldnt go with stage 2 cams because my head isnt ported

 

B18a? B18b? B18c? B18c5?

All at 40......40 what?

If your cam breaks you can bend valves and punch holes in your pistons. You decide if you want to chance it.

If your motor smokes a lot at random times, find out why and fix it.

Best cams? I think you have some other concerns that need to be looked after before you even consider cams.

 

hope he doesn't mean 40 on the pwc , that would be a rattle can with cast pistons

 

b18a block. im not to sure what the 40 means but my block is bored out so its a 1.9 liter n the pistons are oversized to match. why do you think its smoking like that what are some possible explanations for that

 

Probably toasted rings.

 

how could that happen the motor is freshly done with a lil over 200 miles on it new ring new pistons, just about everything

 

if it were the rings wouldnt it constantly smoke?
