The Chronicles Of Area 34, formerly 55

Trying to find pics of where you took your C30 motor apart - do you know roughly the page range that would fall into? Looking for more detail pics of the RNC block & head - I didn't realize how different the breather system is integrated with the lower runners, etc. Just looking for more pics to get a clearer sense of it.

 

EDIT - found this on TB

- which is probably the gist of what I recall you posting, however I thought you had some pics that showed more detail?

What it shows is basically all there is to it. :smile:

Here you can see small channels leading from the cavities between the ports to the ports. RNCb5204t5.jpg

Then there is the manifold gasket with sort of flapper doors in front of the cavities. 

When you look at the manifold there is a chambers surrounding the runners also with openings at the same spot as the cavities. The chamber is also connected to the crank ventilation system. 

When there is vacuum in the runner the flapper door in the gasket can open. When there is boost it will be pushed against the manifold effectively closing the opening.

Thanks for the explanation Johann. I have a gasket on order, but I've never seen one - so couldn't understand how the ports in the lower runner function. Been cleaning up the casting in a spare runner.

Put the P on winter wheels. Came with a lot of hassle because there were no sensors installed in the wheels and dTPMS can't be switched off.

Dealer suggested to software to iTPMS which did tun the display back to showing "green" tires but the no sensor warning in the dash remained. Tomorrow the cr will be changed back to dTPMS and sensors will be installed in the wheels. 

Changed to winter wheels because black ice was to be expected but never showed.. A few days later there was some light snow so the changes wasn't completely useless.

Last night was pretty cold,

E-windows and e-mirrors were frozen.

Appears the P isn't that Swedish anymore. 

The CE even grew what looked like hair,

Same story with the windows and one mirror. Electrical heated windshield did wonders though.
