You should be able to do it from under the car, otherwise remove it and do it outside the car.

FYI as of Sept 2022 the part # identified is unidirectional. There is no longer a lip that needs to point one way or the other

Can you post a photo of the new one?

I'm bumping this one pretty hard. I had an autobody shop disassemble and completely mess up my entire, perfectly working system. After pickup, I found the charge pipe not even connected, gasket hanging out the side. Fixed that and bought a smoke tester after having all kinds of additional problems - major leak on the turbo/boost pipe side.

Bought all new gaskets, which will be here tomorrow

The drawing makes sense to me. I know people talked about low pressure zones and all that, but - when the turbo spools, the entire system becomes pressurized. The one way out is outside of the intercooler ports - down the sides of the pipes, and out. Doing both the turbo side and the charge pipe side the same way - with the V facing up, would make sense to me - as the pressure built and as air hunted for a place to escape, the pressure would force that V open, increasing the seal against the intercooler ports.

I don't believe any low pressure zones exist, or that the direction of airflow matters (because the gaskets are outside of the airflow, in between 2 pipes - the air direction there, in a pressurized system, is always the same - out). The only thing that should matter is that the system is pressurized.

Now - it could be that the seal has a job when pressure releases and the system does go under vacuum, but I have to think they are designed to deal with high pressure and not vacuum.

All that to ask, after all this time, is there any consensus on direction?

This is the diagram that was posted many years ago.

Thank you. Yes, I saw this as well, which is identical to the picture I posted.

My question is, is it correct?

[thejeremyman9]

Yes it is correct, the bevel/taper on the Oring only makes sense one way based on the bevel/taper of the connections

[thejeremyman9]

Or, you can skip the directional ones and get these like i did on some of my connections long ago
