Hi,
I couldn't find anywhere what is the difference between intake and exhaust valve springs on b18c itr?

1. Is there a lenght difference? If yes, which one are longer? I measure them and I think one spring is 1mm longer than the other one..
2. Is there a difference in colour or something else?


Thanks on answers

 

1. Yes, intake side springs free lenght is little bit longer. Refer servicemanual:

Intake outer: 43.19mm
Intake inner: 36.84mm
Exhaust outer: 41.05mm
Exhaust inner: 36.16mm

2. Intake valvesprings have a yellow paint mark and exhaust side blue.

 

Thank you very very much!

 

No problem. And like servicemanual also says, place the end of valvespring with closely wound coils toward the cylinderhead.

 

Sure, I know that, but thanks anyway
