Hi. My first time writing but been reading a lot. I have Opel Adam s with the 1.4t ecotec.
I'm not sure if the valve cover is dead since the car runs kind of okay (loosing power when hot) and making no suction noise until I put my finger on the diaphragm hole, than the engine begin to stumble and make all kinds of noises.
Can you please help me figure out if the cover is dead?

I also preformed a boost leak test and the crankcase was pressurizing. Not at the rate of the air coming through the air pipes but it was significant. I've checked the pcv valve with a cheapo USB endoscope, after spraying some carb cleaner, and the nipple was there. The holes where black but it seems the rubber is behind them just dirty (I'm planning on making the fix).
I believe the pressure in the crankcase from the boost is what shot the valve cover.
What can cause the pressure in the crankcase except the pcv valve failure? Excessive blow by? Something less Intimidating?

Well aware of that. Been reading for months now before I wrote a word
