While trouble shooting idle stability issues I pulled the throttle body and found what looks some kind of fluid pooling in the bottom of the intake plenum. Engine is a completely stock '73 2.0 D-Jet with all EFI components and hoses installed.
Here's a before picture:  And here's what it looked like after a ~40 mile test drive:  The fluid looks green tinted like the Brad Penn I run in the engine and smells like oil/fuel so I'm assuming it's oil. Before the test drive I disconnected the Cold Start Valve just to make sure it couldn't be raw fuel from a leaking valve. I had also cleaned the PCV as well as I could. The PCV unit is at least 25 years and 25K miles old but I can't find a replacement anywhere. Vacuum lines are about 4 years old and seem to still be in good condition. Questions; Is this oil pooling normal? If not what can I do about it? Thanks, John |
