I'm rebuilding my motor, does anyone know the specs for the torque settings and the valve clearance or where it can be found? For a 97' B18C Type R motor.

Thank you in advance!

i'm not sure about jdm motors but usdm c5's are .006 - .007" intake and .007 - .008" exhaust *cold. i don't think there is any difference between jdm and usdm heads so i'd say it'd be safe to go with usdm valve lash specs.

when you say .006-.007int and .007-.008 ex

does that mean you can run .006in & .007ex or .007in & .008ex
what about .006in & .008ex or .007in & .007ex?

If i can not hear the valves ticking that mean they are still in specs and i do not in an adjustment?

anything between those values would be in spec, so .006 would be slightly loose and .007 would be a little tighter. if you havent checked it in a while it wouldnt hurt to check

uhm, .006 is tighter the .007
but i have the valves on the loos side of the scale and living happy with the noisy valves

is it better to run them as tight as possible?

ITRnorway

my expirience with tight valves is burned valves but if you are within specs ill guess you would be okay

going either 6-7 (intake to exhaust respectively) or 7-8, you'll be fine
