Should I tune my valve lifters

I just did my valve clearance check and here is the summary:

Inside range: 12
Barely inside range (meaning at one of the range limits): 7
Outside range: 5

But here is the thing. The five that are outside the range are all barely outside, by 0.001" (one thousandth of an inch).

Do you think I would gain much by tuning (replacing to get in the range) of the 5 that are outside and maybe even the barely ones if I have the cams removed? Or do you think the violations are too small to worry?

 

That is a fuck ton of work for very little gain.

Wait until major engine work is required like a headgasket or timing chain.

 

I am taking the TC off to replace one of the VVT sprockets.

 

May as well! Especially with it all apart.

Make sure to check your tensioners and the idler gear. They are all known for failing.
