Oil catch tank mod

Don't know whether I should post this in the general mods or performance mods so I just posted it here. Here are some pictures.

I used 10 mm polyurethane hoses, to fit inside the pneumatic fittings. I used pneumatic fittings to reduce the use of clamps and easier to remove whenever I empty the tank.

This mod enabled me to replace all the hoses, because the hoses had cracks in them.

NICE! You finally did it! Can we ask you a couple questions?
1) What brand of oil catch tank you used? Maybe Size/dimensions, capacity?
2) Any link to these quick connects on hoses? Their dimensions, diameter. Also line diameters?
3) Any difference in the power loss, throttle response?
4) Is it possible to draw some diagram to know which hose goes where? Which one is inflow/outflow?
5) Is it possible that you report us back after some driving to see how much oil you will collect over the time?
Sorry for soo many questions but after I clean my air nozzles I don't want to come back to them after a while just to see that it's clogged again. I'd like to be done once and then just keep emptying the oil catch tank.

Yup! i finally found the time to do it. Sure, questions are welcome

1. I used the cusco oil catch tank, the size of the tank is 154mm for the height and 80mm wide. It has a .6 liter capacity

2. I didn't research on the polyurethane hoses and pneumatic fittings, initially I wanted to use metal adapters same as the other guy who did this mod, but I wanted the removal to be easier and wanted the hoses to be smaller so the guy who sells power steering hoses and fittings in my area suggested that I use polyurethane hoses and pneumatic fittings, maybe you do a search in the net where you can source the parts or maybe in your local hardware store they sell these. I used 10mm in diameter polyurethane hoses, I bought 1 m long so that I would have room for errors. I also did some fabrication, in the picture, the blue fittings are metal fabricated parts, I did a 3 way metal adapter to include the line coming from the s/c, and also to be able to screw in the pneumatic fittings. I changed all the hoses because the hoses are already brittle.

3. Nope, no difference in the throttle response, and no power loss. If you're going to remove the whole system from the air box to the oil separator, (which I did) be mindful enough to insert it fully again to prevent any boost leak.

4. Hehe, Im not good in drawing stuff. But here's a rough description, the line coming from the engine is the top one in the picture, this line goes into one of the holes of the catch tank. The catch tank holes are interchangeable. Meaning both can either be inflow or outflow. The bottom line in the picture is the one coming from the catch tank and back to the oil separator. This is also where I put the three way adapter to include the line coming from the s/c

5.sure, ill check the catch tank from time to time to report if it will really catch some oil.

All in all this process took me 2.5 hours to do which includes lots of trial and error and fabrication time.

Here's another picture, oh btw, if you have the time, try to clean the oil separator, there's lots of oil left In there, I wasn't able to clean it cause I dint have time left. But when I removed it, my hand got covered in the oil, there were lots of it. Some of the oil even spilled into the big intake hose coming from the intercooler. So maybe this shows that the oil separator is faulty. Oil is left inside there and doesn't go back to the engine.

Thanks for advice! I have already changed all the hoses in that area couple months ago! They were like plastic but not rubber =) Had some oil in the oil separator area. Wasn't that much but my guess would think that it's its job to separate oil and thus some should be left in there.
I still couldn't find any logic behind this oil separator. Perhaps someone will enlighten me: What it's function and what hose is inlet/outlet?

Meanwhile I just got my oil catch can:

Nice you got the mishimoto one. post some pics after you install them. I think the oil separator has a hose going back to the line for the oil dipstick. If you have the money and cash you might also want to try to change that hose to a new one. Oh and I checked my catch can after a week there was no oil but there were traces of oil fumes inside. There was no oil maybe because of the fact that I didn't drive hard this past week. In turbo applications you'll get oil in the catch can if you're always driving in the red line area. So maybe ill experiment if it does the same in this s/c set up.

This one is very neat and sort of small, a Mercedes size =) Capacity is 16 oz.
And yes, I did change every hose in that area =) Was about 5-7 of them. Didn't cost that much so was worth doing it. I was researching this oil separating function and came to conclusion that the best place to install the oil catch tank is right before the PCV valve. This way it's more effective and the PCV valve will live a long life without clogging.
The oil separator is nothing but a piece of plastic with a spiral form inside. It separates oil by centrifugal forces and it drains back into the engine though the dipstick pipe. It also has a valve but it's operated mechanically using air. A good thorough clean up with some plastic/rubber safe cleaner should do the job and you shouldn't worry for the next 70,000 miles or so. All you need is to let it soak so all the build up on the inside walls comes out. The issue is to protect the PCV valve and air nozzles from clogging. I'll post links to different threads with pictures explaining how the oil separator works. Just too much info today =)
But thanks for sharing your results! It seems indeed that more oil enters this pipe when rpms reach above 2,200 when S/C engages and allows more air.

I'll post pictures when I'm done.

OK, here's some additional information about the oil separator:
A thread with a picture how oil separator works:
http://www.benzworld.org/forums/r170...separator.html

and another one:
http://www.benzworld.org/forums/r170...r-advance.html


The oil separators are different for pre- and post- facelift models:
Here's a picture of pre-facelift:
http://www.benzworld.org/forums/r170...separator.html


And here's the post- facelift:


MD molded oil separator into a huge "resonator" and thus it increased its price so it's worthwhile to clean and save yourself $$$'s
It's part 90 on this picture:


The oil gunk accumulates on the sides inside the rubber tubes and oil separator over time. It's a natural process so it needs cleaning/check up every other mileage. I'd say 40,000-50,000.
The problem comes when air nozzles, and PCV valve get blocked. The oil then starts getting into the MAF and problems arise...

Here's the thread on how to clean the nozzles:
http://forums.mercedesclub.org.uk/sh...ad.php?t=34036
As far as I read replacing a PCV valve should be a regular procedure done every 40,000-50,000 miles. The issue here is that it's located in a hardly accessible area under the inlet manifolds and replacing it is a PITA.
So my idea is to install the oil catch can/tank right in front of the PCV to protect it from contamination.
After some more extensive research I've found a very simply DIY oil catch can MOD. I liked it because it's very small and I can install it right in front of the PCV valve rather than installing big oil catch can and routing tubes to it. And it will be above the PCV, and I don't want it (afraid of oil will reside in the tube and make things worse...).
Here are some pictures of this oil catch can from different forums. Can be easily picked up at local Home Depot store. It's a Husky one.

Yup saw those threads too regarding the oil catch can put into place near the pcv valve, that's what most SUV engines do, their pcv valve is accessible, but because I found out that the pcv valve in our engines is really hard to get to, and after reading and researching that it is cheaper to have it replaced in the dealer or independent. I put the catch can near the oil separator instead, rather than do the work of getting to the pcv valve and installing the catch can there. Because after seeing that to get to the pcv valve you have to get past the intake tubes and past the power steering unit, and to get some room to work in there you have to remove the intake tubes and the power steering unit. But if you can do the install near the pcv I would really love to see it and how you were able to get to it.

Can't wait to see what you'll do with yours! and additional update, drove hard for two days, letting the car reach red line 50% of the time I was driving in a straight road with no traffic.. Checked the catch can and there were small amounts of oil and water. Wasn't able to get a picture of it because it didn't pour onto the other container that I have. It was a very small amount, i was able to see the oil only when I shook the can and some of the oil dropped in my hand. It felt like water mixed with a little bit of oil or oil mixed with water.

Be sure to photograph everything; time we had our own DIY on this commonly needed task to clear out the low-flow breather system.
I do wonder if, once you've got that bit working OK, if the high-flow system will then be seen to work OK. (You do need to ensure the drain for the separated oil beside the dipstick is actually clear, else it will separate, and then have to go back into the air-flow as the only way out!)

Jayson were you able to do this occ mod? My friend in california asked me to do a kit for him. So I made one and had it shipped yesterday. If you hadn't done this yet or can't find some one there to do some fabrication. I can send you one ( I won't charge you anything for the fabrication, its free but you have to pay for the parts and the shipping, or I can bring it to the us and you can pick it up where I'm staying, every year I visit the us, I get free airplane tickets from the bank ) or tell you how I did it. Pm me if you want one and we'll discuss it further. Here's the picture of the kit. The parts I used were, 4 metal tubes for fabrication, 4 pneumatic fittings, 2 meters of polyurethane hoses. I used polyurethane hoses because of its durability, they say it can last the lifetime of the car, but I think it depends on how you use it.

I changed the hoses last time and removed oil separator this time too to ensure everything was clean! And it was! Oil separator is doing it's job and I gave it a thorough cleaning with the plastic safe CRC cleaner. Then used my compressor to dry the inside from the contact cleaner. And it means that the drain is not blocked. Otherwise I'd have my butterfly valve all covered in oil...

Great thanks for you offer Jayzen! I might consider it one day =)
I did this mod, just still need to put pictures together. Wasn't that hard but can be seen as PITA. Yes, approximately 4 hours to do the job properly. I opted to use clamps rather than quick connects. 1st because I tried to find the hose that fits the PCV valve and the other that would fit other connection. I used temporary bracket to hold my can. After couple thousand miles I'll be able to see what's going on.

Ok. Looking forward to seeing your pictures, where did you put the occ? Between the engine outlet and before the line coming from the s/c or between the line coming from the s/c and the oil separator? Mine is currently between the engine and the s/c line, I'm gonna try to transfer it between the s/c line and the oil separator cause I've already determined that there is oil coming from the engine. I am trying to determine if the oil would increase if it would be between the s/c line and the oil separator.

Ok here's another update. There really is oil coming from the high load. Here's a picture of the fittings of the occ and when I peeked inside the occ there was oil in there. This is one week driving after cleaning the occ and fittings.

I finally posted it =) You can see where I installed my OCC. Nothing changed. Engine is smooth as kitten! I think I'm back to my 350-370 miles per tank =)
Recently it started declining and I could squeeze only 320 miles out of full tank (a/c always on!). But after I cleaned everything I have 350 miles with the same driving conditions (a/c always on)
