Ok, here we go again....2002 OBW 2.5 SOHC EJ251 Phase 2 sticker under the hood says "Intake = 0.010" , Exhaust 0.015", the Alldata service manual instructions are:

Intake; 0.20 ±0.02 mm (0.0079 ±0.0008 inch)

Exhaust; 0.25 ±0.02 mm (0.0098 ±0.0008 inch)

 

quite different....anyone know which is correct? If the tighter is allowed, I'd like to go that way to try to get rid of the damn noise this thing is making. Thanks,

I just did this job on my '00obw 2.5L EJ251 and used the FSM values of:

Intake 0.20 +/- 0.02 mm

Exhaust 0.25 +/- 0.02 mm

 

My underhood sticker says

Intake 0.10 - 0.25 mm

Exhaust 0.15 - 0.30 mm

 

I'd guess you could go 0.10 and .15 but that appears to be the minimum permitted value which doesn't leave much room for error.
