Hey Folks,
Ive got a set of ITR valve springs to fit to my b16, with cams/retainers/valves and hopefully soon to get some lma's. Ive noticed on the honda parts catalogue that the part numbers are different for the inlet springs and the exhuast. Can anyone help me identify which is which, as when they were sent, they were all jumbled up.

Ive already identified the difference of both inner and outer springs by comparing the start and end point of the springs, so they are split into 4 groups at the moment.
Can anyone tell me how to identify which go on which side?
Thanks

The intake springs should have yellow paint on them, and the exhausts should be marked with blue.

Yeah was aware of the colour coding, but as they are second hand, cant actually see any paint left on the springs

Stiffness is usually controlled by wire diameter. Measure wire diameter with some calipers and see if there is a difference.

Ive identified the 2 different sets of inner and outer springs, just need to find out which go on which side. Was able to tell by the positions which the spring starts and stops. Just need to find out which goes on which side, you think thinker ones should be on exhaust or inlet?

This is solved. Had a quick look at the springs with one of those 1 million candle power torches. Colour became very obvious then!!

Oh, for anyone who need to know, yellow is inlet and blue are exhaust. HTH's.
