This is a must do. I gained 20 who just from cleaning my valves.

The video here is great. So thank you to whomever put the work into that! I'm about to do this job tomorrow morning. I have a shop vac, all the tools and lots of B-12 Chemtool and carb cleaner spray. I need to remove the radiator fan for sure, since I'm also going to be replacing the 2 oil filter housing gaskets as well. That looks pretty simple, but I want to be sure I find all the right bolts and clips that are holding it down.

If all goes well, I'll follow up with my results and the procedures I used. The DIY posts on here have all been very informative, but the N54 is slightly different, especially for the oil filter housing gasket issue.
