i just pulled out the pistons in a b18 block and all the walls look good but for the 3rd one it has a few straches in it. is it ok to just run a hone through it and put the b16 pistons and in it. how will this hurt me the straches that is. or do i need a new block "i hope not"

 

 

waht sort of sctatches, caused by what?

how deep? any pictures?

a hone on all four cylinders may help, depending on hte depth, in most cases you wont need a new block...

t..

 

i dont know what they are from maybe dirt or a bad ring. im going to try to hone it out and see what happens but what i want to know is i should be ok right?

 

Must be them damn piston skirts scraping against your walls. Check the depth of the scores. I'd measure all the cylinders for out-of-round and taper because a bore might be needed before that hone job.

 

what im planning to do is put my pr3 b16 piston that i have on ls rods in it for my ls vtec build. ok thanks for the info

 

any other thoughts on this?

 

B18a's are old. Its safe to assume high milage, and out of round cylinders. I have a b18a and every cylinders is tapered and/or out of round. If you dont do it right you'll do it again. It wont take long for the rings to die. Make sure it right before you assemble it.
