Hi guys. Does anyone have a working diagram of the engine and intakes on the W203 C200 kompressor?
Had an air leak and so ECU was compensating by throwing in petrol. Found a cracked hose: it comes off the engine block, low down, and comes up to a one way valve. After this it goes through a lug on the engine. After this it comes up to the inlet manifold, post butterfly. When we replaced this hose, the old hose was mostly dry with a tiny bit of oil around it where it had cracked, but not loads. To get to this pipe we took off the manifold and injectors. We also replaced the 1 way valve.
Once all back together it began to smoke badly. We took it all apart again, only to find the newly replaced hose was oily, the plastic inlet manifold was full of oil. The supercharger side of the butterfly of the manifold was dry - therefore do not suspect it to be a supercharger related issue. The oil has obviously gone into the combustion chambers too; then drowned the entire exhaust system too. A compression test shows all chambers to have full pressure - pistons therefore ok too.
This replaced hose; is it a breather/recycle for the sump? Can this be the cause? Be good to get a look at what on earth this hose is and what the lug is, that it goes through. A diag anyone?
Cheers in advance.
