depends.

valve lash that is too big will be noisy and reduce performance but won't hurt the engine short term.

valve lash that is too small has the potential to hold the valve partially open during the combustion cycle. that equals burned valves and a head rebuild.

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


These are the OEM specs for the k20a2 motors with a2 cams. Would it be the same for the z1 motor with TSX cams?

Also it says between those numbers, but whats the best to set it at in that range?




Also thanks for the help and the quick replies.

I'm doing a rebuild on my K20Z1, and have the same question as Dc5Asm. (Seeing as most K series are the same) Is it best to set the lash on either end of the stock specs, or just anywhere in that range would be the relatively the same?

Thanks in advance!

I always set the lash on the tight end of the spec range.

the tighter the more horsepower and the looser the more torque. It isn't a lot but that is your guide.

Believe it or not, that actually helps quite a bit. I'd actually heard through the grapevine that the tighter the lash, the more horsepower. Now I have a better idea...

Thanks again guys.

just make it tight enough so you can barely pull the feeler gauge out, but not to tight lol :)
