06 M7 Power Valves Questions

[big10champ2003]

I have a2006 M7. I was having issues with the power valves sticking and instead of dealing with all the adjustments and stuff i bought a set of STM bellow style valves. I installed them and they worked great to start with but after about a tank of gas they started sticking as well. When I took the stock valves out they seemed to be gummed with oil... and I am guessing the new ones are as well. Any ideas as to what would cause this? Looking for any help?

If your valves were stuck you can't just clean the valves and be done. You need to clean the jugs out where the valves slide in as well. There will be a lot of gunk built up in there.
