Still a whole lotta parts gotta come out to get access to the valves! For me, I'm likely to just drive down to Escondido, drop the X5 off and spend the day with friends! Better way to spend the day for me! :thumbup:

You may have watched a video from another shop here in town. I don't think AGA (All German Auto) has released their video yet. The other shop with the "amazing low-def 240p" is probably Escondido German Auto (E.G.A).

I think you are correct. My error.

Regardless, creative solutions to otherwise debilitatingly expensive issues are nice to see!

I hope it is more than just that. I have seen this method performed many times. You need to make sure you get your valves to the closed position. Then there is a tool specifically made to remove and install the valve stem locks.

While the air is being pumped into the cylinder, you whack the locks with said tool, and you got the locks off. Remove, replace seals and move on.

This.
Motion Pro Valve Core Remover - Dirt Bike Motocross - Motorcycle Superstore

And Leak down tester used to pump air in.

I hope A B has a cooler way to do this.

Dealership told me it's an 8K job as well. I contacted the master tech who does the job, he definitely knows his stuff. For 8k you might as well get a different engine installed. As of now I'm going through a an oil change jug a month until I get it done. I'll be replacing the cats after the job when the time comes around with some aftermarket "high flow" units. My X is running full steam ahead as of now, but I'm sure it can't be to healthy for it to be blowing that much oil out the exhaust.

I honestly don't think I could suggest anything to Martin from AGA that he already hasn't thought of - he's a smart guy.

Just to keep you interested - two more tidpits of information about the tools and process.

- A failsafe in the event you drop a keeper
- A tool that facilitates the installation of keepers in a matter of seconds

Looking forward to it :thumb up:

The only thing that would make it better if it could be done from on the couch with a cold one...
