Hard to give absolute psi value that might show up on the compression test. Way too many variables, so it could vary from none/0psi if shims are proper sized or undersized, no carbon buildup, valve seats and faces with no/low wear to many psi if valve faces don't properly meet the seats (which might not always be corrected by simply using a proper shim/adjustment).

For valve cover gasket, if you have proper viton gasket, it can be reused, other should probably be replaced as they are more "single use" and might leak if reused.

That definitely didn't complicate things

Sounds as though : compression test IN CURRENT STATE

Thanks a lot for this guide. I was quoted $1000 CDN from a very good shop for an adjustment with all parts included. At this rate, it's worth it for me to attempt this myself since it can be done in one day, and I can save $900 after taxes. Plus I want to learn more about my car.

Please confirm if this ECS kit has all of the parts AND TOOLS that I need to follow this guide thoroughly:

Wow, that is an expensive quote...

I want to be clear with my answer to your question about ECS kit...it has the parts and tools needed to perform the actual valve adjustment (sans micrometer to measure shims), however, these are not ALL the tools needed. It obviously does not come with any of the tools in the "Tools needed" section of the first post, to for example, remove the valve cover or rotate the engine, or even measure the shims (no micrometer in the kit), since it doesn't have the ratchets, box/open end wrenches, etc. Might be obvious, but I wanted to be clear, since you bolded "AND TOOLS" after using "all" in your question...

Great write up! I am picking up my new (to me) E46 M3 tomorrow. This is probably going to be the first thing I do to it. The car has 107k miles on it, after pulling everything to do the valve adjustment I am wondering if there is anything I should just go ahead and replace since I am in there?

Obviously, I will replace anything that is obviously worn (i.e. belts, hoses, etc...)

Worth it to change water pump, thermostat, xxx? Go ahead and do Vanos check/update as well?

Everything you mentioned if you dont have records of them being done. Flush and replace all fluids. If you are doing belts, might be a good time to do tensioner/idler pulleys.

And congrats!
