I hate to tell you guys, but it's not if the oil filter housing gasket will fail, it will be when.
It's happening more and more and there's a DIY already but I thought I would add some more pictures.
Since the Intake Manifold needs to come out, I thought I would clean the valves.
It really wasn't that much work, but it was tedious.
This is what I used:
-A crap load of Brake Cleaner (I used 2 cans but probably could have used more)
-A long flat head screw driver to scrape the valves
-A stainless steel wire brush to clean the ports
-Shop Vac to suck out any excess brake cleaner and dirt/grime
If I were to do it again:
-A longer flat had screwdriver with a smaller head
-A long long brush. A guy at work told me about a rifle cleaning brush. That's a great idea.
Something to keep in mind:
My friend is a BMW tech and said that when they clean the valves, they bring each cylinder to top dead center and put in a strong cleaning solution and let it sit. He said that this slution is a lot stronger than carb cleaner. They do not scrape anything because they don't want to ruin the finish on the valves, but I think that if you were to use a softer brush then everything will be fine. It's definitely something to think about though.
