My R-56 2011 valve cover does not have a PCV valve from what I can tell. How do I sea form my "intake"?

 

Upper left corner of the valve cover has a small rounded rectangular cover that houses the PCV diaphragm. Don't open this unless you have a spare one to put in as they usually are toast at that age. Look for Mr. Grumpy thread on this detailing where to buy and how to replace.

Is that the proper spot for Sea Foam? Don't know and not sure that Sea Foam is going to do much for these cars if you are trying to clean valves. If it is just intake, etc. you can probably find threads here of others who have done this.

 

Pour it in the gas tank.

 

Pouring it in the gas tank does nothing to clean the valves in a gas direct injected engine.

I read you spray or pour it in the hose at the back of the valve cover.

 

Not on my engine. I have the N18.

 

And that would go directly into the cylinder doing notta for the fuel intake coking which is what I want to maintain.

The N12 engine does not coke the valves like the N14.

 

You cannot put seafoam via a completely closed membrane.

I have learned that on the N18 there is a hose on the lower right side that goes directly into the Turbo from the Valve cover. You have to push the sea foam in there using a straw to make sure you go past the sensor that is there. I'm like 92% sure at least that is how.

 

here is where it appears to be...
