The 3.6 isn't generally associated with the intermix issue of the 3.4 - can't totally rule it out but it would be worth checking the coolant tank.

Looks like left side I'd check the AOS you that area by putting your head under the right rear wheel with a torch (flashlight).

Are you sure that oil leak wasn't there before and you've just seen it now?

Positive, mainly cause I saw the pool of liquid. It didnt look like oil but going back to it it seems so. Is the AOS all the way in the back of the engine? Cause that’s what I saw soaked

Yes AOS is far back left side when you're facing the engine.

You can even feel it if you shove your hand in from the left side and follow the hose that leads to it next to the coolant tank.

Could be possible that you have a dead AOS - actually not a bad outcome if that's the case.

02 here and I just went through the AOS failure 3 weeks ago. I hope that's it. Not sure why I thought you had an 01 until I looked at your avatar closer.

Uh oh, sorry when I said Rear I meant relative to front of car. So in your terms that means driver side front if you face the engine.

Pull the AOS tube off of the throttle body and see if there's oil in it.

When you're facing the engine with the lid open - it's on the left side rear.

Gotcha. Any idea what would be on the lift side front? Maybe the oil pump? Because that’s where I saw it gushing from and in the pics whereboil marks are found

Not a whole lot that could leak I dont think - maybe the green plastic cam lock covers.

Look for the two green cam plugs on the left head. They are known to blow out.

Parents noticed and want me to take my car to my Indy. I have some time so let me know what else to look for

edit: I am calling for a tow truck thought I should clear this up. It may be that the spray from yesterday was oil and coolant mixing.

That's not good, id wait until your Indy looks at it.

Are they are Porsche specialist?

They do work for a reputable Porsche dealer in my area so I’d say so. They have worked in my car for as long as I’ve owned it.
