Can anybody please tell me the part number to these pistons?
I took them out of my 85mm B18c1 Gsr motor
There Je pistons, on the inside it says 81md4
Can anybody please help. Any help is appreciated.
Piston Specs: Je 85mm 9:1 Cr for Honda/Acura B series

(Noob Question warning!)
By any chance does anybody know if these require like special rings or something cause the bottom pistons ring came out the motor pretty loose and it made my car burn oil and smoke i want to get rid of this problem a friend told me something about an oil ring spacer but i called the Je company and gave them the Part number 185918 the part number i thought the pistons were)
and they said that piston part number doesnt come with oil ring spacers
So im fresh out of ideas but there does seem to be something missing cause the bottom rings fit loose

non-VTEC

if they are recent JE forgings they should have the part numbers etched into the bottom of the pistons.

even if there is no part number it shouldn't be to hard to figure out. they probably only have one or two listing for a 85mm low compression piston. check out the website.

my guess is the part number: 185918

Just ask a JE distributor for Honda 85mm rings. All piston makers tend to use the same ring size for a given motor forever, since they'd have to change the pistons and rings they stock to go with a new size.

They generally are a full $100 kit, but some dealers may sell them individually. If you had a piston in there w/o the oil control rings (2 thin bottom rings) or the oil ring spacer (wavy thing), yes it will let tons of oil in. They generally don't have to be filed/gapped, since they aren't sealing any pressure zones.

Just use JE rings, we have a set in stock that we can ship out today if needed.
