Trying to get a definitive answer regarding valve clearances for the K20Z4 engine. Looking at various threads it appears to be as follows but if anyone has access to the workshop manual and could confirm that would be appreciated.

Intake: 0.21-0.25 mm (0.008-0.010 in.)
Exhaust: 0.25-0.29 mm (0.010-0.011 in.)

That's the same as the k20a2 in my ep3, can't imagine the fn2 will be different, but not 100% sure on that.

From Honda workshop manual:

Intake: 0.18−0.22 mm (0.007−0.009 in.)

Exhaust: 0.23−0.27 mm (0.009−0.011 in.)



EDIT by M8TJT
It appears that the above figures are not correct for the FN2 K20Z4 engine.
See post #6 and #1

Thanks but that’s my concern as different posts in various forums suggest different clearances. Can you confirm that the workshop manual data you posted is for the K20Z4 engine. Sorry to be pedantic. Appreciate everyone’s input.

Ok folks I managed to get access to the workshop manual for the FN2 K20Z engine and it seems that the clearances I posted match what is in the manual. Thanks to everyone who responded to my post.

I'm glad you double checked, an apology owed on my part as at some point the dropdown in the shop manual had changed to the FN1 from the FN2.

You are indeed correct, and for anyone stumbling across this, to correct my previous post the manual states:

Valve Clearance

Intake: 0.21−0.25 mm (0.008−0.010 in.)
Exhaust: 0.25−0.29 mm (0.010−0.011 in.)
