Is there anyway to see if the piston rings are good or bad on a b18 shortblock. i tried moving the pistons around they did move but it wasnt much.

 

a leakdown test along with compression test will show ya if the motor is still assembled

edit - doh... sorry, looks like the head is off of the block huh

 

take the rings off the pistons, put them back in the cylinder, turn the piston upside down to push the ring down a lil to make sure it is in there perfectly paralelle with the block deck, than use a feeler guage to check the end gaps of the rings... ur gona have to find out what the end gap is suppose to be cuz i dunno. of corse u will have to take the bottom end apart but its better to do it now than later... good luck. :
p.s.
replace the bearings while ur at it.

 

I have some b16 piston with 3,000 miles on the rings i think im gonna slap those in and get new bearings. I shouldn't have any problems since the rings are already kinda used right??

This is my friends car that im selling the parts too, and im doing all the work.

 

they shouldint leak now if they didint leak b4
