Ive been getting oily smell in the cabin since i baught the car 6 months ago.
I tried a few of the common fixes (rocker cover gasket was leaking and the dipstick tube was cracked) but the problem persists.
Today i was topping up the oil and while having a general look over the engine bay i noticed a pipe under the inlet manifold seemed to be wet with oil. At first i presumed it was just a rubber hose thats perished away as they often do when exposed to oil, however on closer inspection it seems that its either snapped at a fitting, or simply come detached...
i took some images:
looking down thru the inlet runners beside the dipstick you can see the pipe start:
It seems to come off the block at an angle, turn sharply back towards the block then turn sharply again and run along its length until this fitting:
Which you can see has a gap between it and the rest of the pipe. It seems to then feed into a much smaller pipe that runs upto the inlet manifold.
Is this just the crankcase breather and does it just connect to the inlet manifold?
if so, why hasnt the car experienced any running issues as i would expect that pipe will be allowing unmetered air into the inlet tract, (or letting boost out...)
