AAAAAaaahhhh Freak Out!!! (valve adjustment)

What's up people... just wanted to share my experience while adjusting or checking the shims in the ///Z4M.

I'm have a feeling that BMW never checked the valves or shims in my car. I was only able to get a report from the Austin dealership and the reports mentioned an oil leak before I bought it and the engine gasket covert was replace t 20k miles.

Anyhow, to measure the intake side I used .007 of an inch to .009 as the max. All my intake vales were set to allow in .007 and .008 NOT .009 and .011 to .013 for the exhaust side allowing in .011 and .012 NOT .013

To make the story short ALL of my shims were too small, allowing .010 and higher on the intake side and one exhaust valve allowed a .016. This job is not difficult, but it requires that you pay attention and double check your work to make sure is done right!

Below is an FYI video in regards to the retainer or the bracket that keeps the rockers from move to the side.... again, it's just an FYI.
