Mondeo 2.5t pcv oil filler cap pressure

Recommended Posts

hi all, 

Today i replace the diaphram inside the cap of the pcv system of my 2007 2.5t mondeo. I didnt have any positive pressure at the dipstick or oil filler cap, but to be preventive i changed the diaphram (only 20 dollars).

However installation was challenging due to limit space in the engine bay 


Now i doubt if the spring was 100% correctly seated.

I have a nice slight vacuum at my oil filler cap (handglove test). 


Is there still change i screwed up? Or it the handglove test THE test ?
