i lost about 100 miles per tank, so started investigating. I need help on below pics. my marks didn't appear on pics so, i'll just describe.

what part is this? it looks wet. is it gas? (the rusty square piece with a Phillips screw on top.)

what part is this? is it suppose to look oily?

do I have this hose routed correctly to my intake? (the black hose)


thanks everyone.

1. thats the water valve for the heater core
2. thats the PCV valve i think
3. not sure, but that hose looks like its cracking and probably rotten.

yeah i've lost some MPG too, I think its just time for a tune up... I did spark plugs and wires a while ago.. but just swapped out Distributer cap and rotor... so hoping that helps..

the black hose is connected properly

winter gas for me, I used to get 450 for a tank now i get like 350ish...

yea same here im suffering bad too... i lost about 100 miles off my tank too

check why is leaking on pic 2 and replace PCV valve or hose. 3rd pic hose looks wrong, you can cap both sides off. You are already getting air to the valve by the side of the intake.
