Okay, getting ready to do my 12k service/first valve check. What do you folks use to seal the new gasket up? Old posts talk about Three Bond 1209 as listed in the manual as being unavailable here in the US (they have an office in Cincy so I am going to call to found this out for myself). What specific brand are all you folks that do your own valves using? O2 sensor safe seems to be the main theme.

I've used Permatex Sensor Safe High Temp RTV Silicone Gasket Maker with good success. I think I used it at 12K, 24K and just yesterday at 36K. I did not use it a year ago when I did a timing cover repair and I believe it weeped out the half-moon holes.
I'll post a photo in a minute. Good luck.

Silicone Remover and ThreeBond 1207B

Recently, I had to remove silicone from some engine gasket surfaces and tried for the first time Permatex Silicone Stripper Gasket Remover. Silicone can be stubborn to remove and this gasket remover made the job a bunch easier. I found it at my local auto parts store.

When choosing a liquid gasket, I have had good success with ThreeBond 1207B. I purchase it from a BMW dealership.
