^^^ Yes the condition of your oil can be attributed to short trips & how long it has been in there. If you can only do short trips because of your life situation you may want to consider changing your oil more often. Oil is much cheaper than engine rebuilds.

 

Well since you are 17 going to high school and working 30 hours a week that very understandable.

 

:lol:

 

.......and on a more realistic planet D) the catch can on an R53 will simply remove whatever blow-by you get from mucking up the IC. I dump mine at every oil change and I get 3-6 oz's of muck. I prefer to keep it out of my IC where it can get a bit baked on.

As to the proper connections, you need to make sure you keep those two vacuum lines separate as it can cause a low vacuum condition which will cause the build up of moisture in the oil. The reason to use the high vacuum line to the SC is simply because that is where the most potential for muck is going to come from.

 

:lol::lol::lol::lol::lol:Yeah that's my problem. :crazy::crazy::lol::lol:

 

:cornut: What M7, nah that couldn't be as they're right up there with Alta.:devil::crazy::ihih::lol::yikes:

What you are seeing is a water/oil emulsion.... Looks like nasty mayonnaise...
Do what Crashton said.... Take a run on the freeway and get the temperature up and hold it there for a while.... Long enough for the heat to separate the water from the oil emulsion and it will vent as steam..... In effect you are needing to create a distillation process and the oil water moisture will separate....

Short runs are not letting the temperature get high enough to cause the two to seperate....

 

I got 99 problems but an oil catch can ain't one.

 

As one who has had a catch can for 8+ yrs on my R53 I can say with certainty that it is indeed a good idea to have one as there will always be SOME blowby. But the biggest concern is to make sure you have it installed correctly. If you don't you can and will get the mustardy/mayo-looking oil residue.

I have attached the correct way to install the can. You want to make sure that it is connected to the gray high vacuum line located under the IC NOT the line that connects next to the throttle body(leave this one in place).

 

Old pic.......no red coily-thingy anymore. I don't collect a lot of oil residue, but it sure does do a great job of keeping it out of my IC!

 

Cool, I just don't want to see you guys f up your great cars. Did you get also get rid of the silicone IC couplers? Those things are known to cause boost leaks and kill power output.

I know this because I had them at one time myself and had low boost issues. I went back to a new set of OEM boots and they seal better and all my boost leak have never returned.

The last one sums me up. :lol:

 

:cornut: Change the filter and fill it up (4qts) with the correct oil. Observe the color and consistency of the oil on the dipstick 3x weekly. This with tell you if anything else is needed. Good Luck.
