Oil in engine bay, need help
https://cimg5.ibsrv.net/gimg/www.evo...16d8cc90ca.jpg
https://cimg6.ibsrv.net/gimg/www.evo...542d005419.jpg Last weekend after I came back from track event I noticed oil on top of my upper intercooler piping, some also spilled to the back (circled in red). I checked coolant and engine oil but not seeing much change, probably because it's only a small amount of spill. I need some ideas on what could it be and where could it be coming from. |
I'd start by checking the cam sensor housings for any oil but its hard to understand how it would get way up by the booster from that.
Could be that it was leaking somewhere on the back of the block(MIVEC feed) and the turbulence threw it up there so I'd check that too. |
I doubt this is it, cause you probably would of noticed it in the peddle but check your clutch line for cracks/ pooled fluid.

vent cover missing out of the transmission maybe?

I checked cam sensor housing it doesn't look like leaking. I did a short test drive and did not see any oil again. A mysterious leak:confused:

Where does this go: https://cimg7.ibsrv.net/gimg/www.evo...53ebbcbdef.png If that is tied off or goes to a catch can, perhaps the extra blow by generated by tracking is venting into the engine bay? Hope you figure it out. |

Hey man. Something came to mind based on your pictures and description.

I think that's a intake line. It connect to the intake pipe. My catch can is on the far left side. But I did overfilled oil during track days just to be safe.
There is something peculiar here though: https://cimg0.ibsrv.net/gimg/www.evo...e2d573766f.png Maybe it's the camera angle, but it looks like you don't have a diverter valve... is that plugged? |

That seems normal, that's how the stock hose is routed, takes blow-by from the valve cover back into the intake.
