Long story short:
My cylinder head has been dismounted completely (not by me), and the amateur has put everything in a box.
So when he's mounting it again, he discovers that "wow, the valve springs aren't identical. wtf do I do now?"
So he calls me wondering, and I sure don't know. There's a reason I had him do the job..
Do any of you know?
The difference between them is that one of them is more "pointy" or "sharp", and mx5parts.co.uk differ on the part number. They don't show what is what though..
SI4517 is for the inlet valves
SI4508 is for the exhaust valves
I need a visual description of the difference, and the answer to which valve springs to on which valves.
Oh yeah, did I mention that I need the info fairly quick?
