Oil on/around Intake Manifold - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Wepeel · 05-12-2014, 09:29 AM

So I started noticing some oil spots on the intake manifold, on the driver side. Looked around for a bit, but can't seem to find where it's coming from. I'm thinking it could be some pcv/breather/evap line that came disconnected, but before I take it in to the dealer I'm just wondering if anyone else has experienced this?

Seems like guys in the FI forums seem to have issues with lines popping off but I am NA.

Where are you seeing oil specifically? Breather tube is behind AC compressor but that does not easily come loose. Sure its not the AC compressor. Any oil pooled by fiiter sandwich plate?

It was on the edge of the intake manifold, on the driver-front runner, and also in the valley between the front/rear runner just under the D4S plate. Also noticed some on the wire with the blue harness near the driver front under the manifold, I think that's the direct injector solenoid harness?

I just realized I did trans fluid swap recently and had the funnel wedged against the intake manifold. I'm hoping I just dripped some gear oil on the manifold parts and it spread out with heat/time/etc. When I went to wipe it up it wasn't that much. It's all cleaned up now, I will check to see if anything new appears.
