Default Working on a valve lash spreadsheet...

Hello!

On my EJ257, i'm currently at the stage of measuring the valve lash to get the correct valve buckets. While I was at work, I got a little bored a created a google sheets that can help with the math to find the right bucket size.

Anyone with experience able to double check my work? If it seems to work, i can gladly share this with the group (if it's helpful...it's pretty simple math).

How it works:
1) Get your valvetrain to the point where you are measuring your valve lash
2) On the spreadsheet, enter the valve lash for each valve and bucket under the "Actual Clearance" row. I labeled it Front to Rear to make it easier.
3) Insert the goal spec on the row below "Actual Clearance"
4) Insert the bucket that is currently installed on that valve (in mm)
5) The last row will display which bucket is suggested based off the above values.

Feel free to input some number to see if it looks right to you or not.

Thanks!

I like this idea, anything that double checks back of the napkin math and keeps things organized is a good idea in my book.

I cloned "Sheet 1" and made some changes based on how I like to work. I converted the measurements taken to thousands of an inch as I believe thats what most people will have for feeler gauges. The idea is that you enter the largest gauge value you could fit along with your current bucket number and it will tell you the bucket number you need.

I also dropped some columns because we only have 8 valves /head or 16 total

Also added some cell formatting so numbers are easy to read e.g. display .010 instead of .01

Great spreadsheet and thanks for posting!

One thing worth mentioning is the buckets do wear over time so i’d Measure them versus just going off the buckets number.
