Mystery oil on bonnet scoop area
 

Wonder if you guys could advise.

This morning I started the WRX as usual and moved out. The car vibrated a bit when cold but soon it was going as normal.

A little while later I noticed some drops of oil at the bonnet scoop area (about 8 small drops) closer to the driver side.

Popped the bonnet and did not notice anything leaking. Engine oil cap was tight.

Drove it for a distance and no smoke or smell coming from the engine bay or exhaust.

I was sure that I did not spill any oil around the bonnet scoop area as the car is parked most of the time under cover.

Funny thing is that the oil seemed clean. I rubbed it between my fingers and it definitely was not water.

I still have the spiltter below the bonnet scoop.

Where could the oil come from? I did some searching and it seems that if the turbo seals are blown, then there would be heaps of smoke? Or could it be the turbo return lines, but wouldn't a leak affect the performance of the turbo?

Thanks in advance for any help.

Cheers

when you say 'bonnet scoop area' do you mean inside the bonnet or on the outside?

Do you have an atmo BOV pointing towards this "bonnet scoop area"?

yeah sounds like blow by either coming from the bov... leak in the tmic rubber joiner... disconnected rocker cover breather
