Routing excess oil separator out of engine bay
Hey guys,
I bought this intake kit: Mercedes Diesel Performance Air Intake Kit 300D | eBay Probably way overpriced, probably could've made a DIY one for way less, but I really like it and it looks great in the engine bay, also gives the turbo a sweet sound. The shorter, upper separator gets the actual oil to the oil return line and the blow by to the longer tube. The longer collector vents the blow by out and collects any oil that makes it out. The collector just vents out into a long hose which you just kind of tuck under the battery tray into the back of the engine bay. Great design IMO, but I have one of those engines that despite having terrific signs of life, just has a bit more blow by than it should. I've learned not to worry, but the tube just vents it out into the engine bay and makes my engine bay kinda smoky when the car is running. Not a huge deal, but something I'd like to maybe resolve. I had an idea of going down the exhaust, and drilling a hole in the mid-pipe region, and getting a little threaded tube fitting, then just mounting a longer hose to the collector and running the hose to the fitting on the exhaust. This would just vent the blow by into the exhaust and out the back of the car. Is this a good idea? As in, would I have to worry about the exhaust trying to push its way up the tube and into the collector, thus creating pressure in the whole system? Or do you think the exhaust would flow by it and let the blow by just flow in with it? |
that blowbye really needs to go back into the intake. you could drill and tap that metal elbow and install a hose barb, or use one of these on your silicone reducer: http://www.siliconeintakes.com/product_info.php?cPath=12&products_id=500&osCsid=70b92d508f5fa389a2206159c3f5c625
did you see my version? time to pimp my thread... http://www.peachparts.com/shopforum/diesel-discussion/327970-catch-can-cold-hot-air-intake-how.html |
Drill a hole in the tube right after the air filter and route the blowby back into the turbo. That's what MB did on the early 617's in the 116 chassis.
By the way, I don't get the point of that kit. I see no advantage over the OE setup. |

Ugh. another member lowering the performance of his vehicle to gain turbo whine and poorly filtered air to the engine.
lets see some pics of it installed on your car. you understand the stock air filter flows MORE air than the car can possibly use right? I understand that the rattling broken mount is SUPREMELY annoying, and hearing that turbo whine is appealing to say the least, but it will get annoying after time, and the foam/oil filters really cannot filter the volume of air a diesel ingests! I would route the smokey air back into the intake as pgirngo suggests. I'd also change that filter to at least a paper element, and install a heat shield to surround it, and get a fresh air intake routed into the box. |

As for your opinionated prediction on how you think I will feel about something on my own car, thank you, but no thank you. Quote:

You`re young, go for it, but in the end when you get through spinning your wheels trying to modify everything. you will just drive them and enjoy them. other things will take up your time.
wife, kids, working, paying bills/taxes, rent. house payment, trying to survive, paying off the ex/alamony, (all the money) child support. :D Yeah VSTECH knows what he is talking about for sure. Charlie |

Can the mods close this thread? I have my answer for the tech aspect of the question. Anything else from here would only be needless banter.
