Another Oil Filter Housing Leak/Intake Valve Deep Cleaning (with DYNOS)
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. Dynos of the power differences are posted on post number 71. http://www.e90post.com/forums/showpo...0&postcount=71 Here are some pics.

Nice write up. I just took my car in to BMW because my car is eating oil quickly. It went from being topped off to saying I need to add a quart in 700 miles. I told them I think it's the oil filter housing gasket, and the SA said it was unlikely, although I'm pretty damn sure it's the problem. Hopefully they do actually check it like I told them. *crosses fingers*

No oil cooler will contribute to this. Quote:
I just made sure that the surface of the head was very clean and I took a little bit of oil and made sure each gasket was moist. I have about 25-30k miles on meth.

I've had a catch can since 20k miles. 19 Nm Quote:
The gaskets are the issue here. That's why we are seeing so many failures. it has nothing to do with what oil cooler one has. Look at the DIY and you'll see that the guy that posted it had his fail and he doesn't even have an OC. lol

Any thoughts on using high temp silicon gasket maker as a gasket for the housing. In all likelihood the gaskets we use to replace the damaged one will fail as well.
Perhaps a high temp option may prevent that in the future. There is a nice groove to follow so there would probably be minimal spillage. |

Mine looked worse.
Bolts are cheap but I used some I found at Loews. 7x1.0x50. fit fine. Not sure what the repercussions of using headed bolts instead 2 sided bmw bolts. Mine snapped on the third replacement of the intake manifold so I replaced them with the bolts from Lowes. How did you get the plastic bank of wires off the bottom of the manifold? I saw some clips but couldn't get them to release??
