Oil Catch can
Is this need on an S55 platform as much I needed it on my N54?

While it seems like your engine is not "puking" oil/gas (and I would not expect this engine to do that - especially at 4k miles), given the cost of this mod, it still seems worth it to me now. A few quick questions... 1. Is this the BMS Oil Catch Can? 2. Are you modded? If so, how much?

I have the BMS OCC on my car. It's not a daily driver so it sits for days, sometimes longer. I installed the OCC at 100 miles and am at ~2500 miles now. I cleaned it at 1200 miles and again at 2200 miles. Both times it was about 1/6 filled with oil vapor and water condensation.
I would say it's a worth while mod on the S55.

I think its worth it like you said even if its just piece of mind, had them on my last 2 cars(both mustangs) so it was an automatic upgrade for me. Mildly modified with BMC drop ins and charcoal filters removed, AWE non resonated, BMS charge pipes and JB4. And yes this is the BMS catch can.

So I finally got around to ordering and installing my oil catch can yesterday. The install was a modest PITA since the OEM hose did not want to come off easy. But taking it out to drain it seems like more of a PITA than I thought it would be. Still glad I got it, but am I missing something or am I going to have to fully uninstall it to drain it?

I tried the BMS one. It didn't fit where it was supposed to. I blame my intake. but they sure don't give you much to work with. I suspected emptying it would have been a bitch if I did finally manage to get it installed.

I am thinking about possibly adding a drain hose w/shut off valve and routing it to the oil drain plug location so I don't have to remove it in the future.

So I did my first interim oil change yesterday at 51XX miles, with the BMS OCC on the car for ~3500 miles. I was not expecting much of anything given the low milage since the OCC install and based on what others have seen. However, I was surprised at just how bone dry the OCC was. I guess this means that maybe my "modified" break-in procedure may have worked better than I thought to help seal those piston rings ......
Anyway, I am still glad I did this mod though and would still recommend it as this is not an expensive modification by any means. As healthy and as well designed as the S55 engine may be, there will always be some blow-by as the engine ages. Next inspection will be in ~5k miles or so with the next oil change. Pic below of what I saw when I went to drain it...

Only reason I've never done one on my current car is that they can freeze and cause serious running issues with frozen sludge in them. I'm in Chicago. Anywhere the winter doesn't suck balls I'd get one.

Installed mine at 500 miles. Checked again at 5k and 10k miles. Not a drop. Put tune on at 10k so it will be interesting to see if there is any difference at 15k. Very different experience with my N54 engine. Although my prior tuned N55 didn't show anything either similar to the S55.

Thought I would add some more data to this thread.....
I just checked my OCC at the 10k mile mark prior to my oil change. Here is what I saw after approximately 5k miles since the last time I checked it. Approx 1-2 oz of oil/water condensation with some sludge at the bottom. My engine is completely stock other than some AFE drop in air filters. Still glad I got it....

Does anybody have an easy way to check the oil in this? I mean I received mine today and cant even see how you can get this in without removing the strut brace or forcing it down there :/ so the convenience of checking the oil is going to be a bit of a PITA. I got it as i have alot of, what looked like, blow by in and around my charge pipes.

Just installed mine. 10 min at most
It's a tight fit. You can install it without removing the strut bar by wiggling it in sideways right next to the radiator and once it's in than you just turn it in upright position Another tip is that you can pull up on the pvc hose cover so it's flush like mine and you won't see the ugly stitching I can't see the can being able to be removed unless you remove the left side air intake or the entire oil catch can I'll check in 1k miles to see if it caught anything at all |

I also add some painters tape in the area to minimize the chances for scratches to the car, the strut brace and the can as it is still a bit tight in there.

On top of that the two split hoses near where the can rest seem to get in the way? Any tips on this? Cheers

The catchcan is especially important if you use E85 and high boost a lot . Hopefully there is a vacuum source connected to the catchcan as well.
