Valve noise after adjustment. Video included
 

So this morning I adjusted valves on my 13' Sports. All exhaust were super tight, in the .006 range. The engine has been getting very queit so I already suspected it. Intake side was ok, few were bit loose.

Spark plugs were replaced to ik22s, although stock ones were in excellent shape. I also installed Spoon throttle body

The car runs beautiful, no CEL , smooth idle and excellent pick up but the valve train noise is way, way louder. I put the exhaust valves at 0.012 thinking they will loose overtime but didn't think they will get this noisy. I'm just about to install Ktuner and I'm not sure if I should leave like this or go ahead and get the lash down to 0.010 on the exaust side.

Here is the video:

It sounds a bit too loose, I did mine this week and I had to do it three times before getting it correctly.
My rule is this: anything greater than the range should NOT fit at all.

Hope this helps.

I see.

I'm doing it tomorrow morning again. Will use the go-no go technique. Will go with 0.010 on exhaust side and 0.006 on intake side.

So I redo all the valves again and the car purrs like a kitten now :bowdown:. There were all too loose on the exhaust side. There was a "drag" on .012 but you could fit .014 .

Awesome!
Doesn't it feel so satisfying? Good to know the second try fixed it.

Oh yeah definitely. And now I can get to the valves in less than 20min :thumbups:

Good info.
I'm about to venture into my first valve adjustment.
Did buy the auto transmission filter as I'll be taking apart quite a few parts too.

Hi, just wanted to add, the exhaust valves always tighten, not loosen, so should be set at their max. Intake set middle or low range

My had a similar sound after I adjusted the valves. The 1st time doing it was a little loose and realized I let the shim slide to easily. 2nd time doing it lessin the noise.
