i know i am not in this forum very often so i dont know if this has been discussed recently. i just posted in the sticky in the ka forum on cam alignment.

DONT GO BY THE COLORED PAINT ON THE CAMS

it means nothing. i just rebuilt two heads with opposite paint schemes on the cams.

lol, my friend ruined a head due to this. I'm not sure why he didn't turn it over by hand before starting it up, but whatever, it still happened.

The paint means something...

1st, identify the intake cam...look at the front of the cam...it's the one with the dowel pin @ 12o'clock when the 1st pair of lobes is pointing straight up.

S13 intake is green, exhaust is orange.

S14 is opposite (intake is orange, exhaust is green).

FWIW...

Glad this was brought to my attention because I would have probably just wasted a motor because I trust paint to much some times and my gut feeling would have been the same thing to trust the paint, thanks for the info.Peace,Pat

The colors get mixed up do to people swapping in S13 cam combos. But I'm pretty sure Brian has it correct. Atleast identifying the intake cam anyway. WD

i swear i just pulled apart two s13 heads with opposite color schemes. the only way i can see this is if the head had s14 cams or if the colors are less than accurate.

Can anyone confirm this?I mixed up my cams, and one matches what he described above, as the intake.Just to be sure before I do anything if anyone can verify this...

Brian's info doesnt need to be verified. It's fact.

If you dont believe it look in the FSM.

i believe i too messed up a head cause of bad cam identification(i mixed up S13 & S14 cams:P)

could have been that the previous owner changed heads or something.

Bah! I went and put them in (in the above specified order) and began to torque all the bolts, when the #1 bolt snapped off . Now im afraid they'll all do that. Does anybody know where I can get a new set? (And how to get the old one out)?

Drill a hole in the bolt...then use a extract tool has reversed threads to catch on the bolt.

what gives, that happened to me, but it was 1 of the bolts on the last exhaust cap, this was last saturday, and i tried those "easyouts" that didn't work for me so am gonna have to try drillin it out and puttin a helicoil.......

hope it works for ya though vannelson, as its really not that easy to drill out the hole without a steady hand.

Thanks - brilliant idea! This was, by the way, on the exhaust cam. I went to tighten the bolts on the intake, and got them all to 2nm's, then started to get them on to 10nm's, and the bolt felt like it was just turning, and not getting tighter, so I gave up for now. Thing probably broke, but I don't want to know right now...
