condensation of moisture from heating of the pipes
might be a faulty egr valve or something wrong with the vacumme lines
will have a look at my stock std TM in the day light and follow the plumbing
and repost

but shorley not enough to fill the pan bace of the airfilter, the egr vavle works because that was a previous problem on how if was renstalled (no gasket), whats the vavle on that section of pipe is that ment to shut off?

clean and complete combustion will create allot of moisture as it is. it could be that when the exhaust system is cold the steam condensates back into water and is sucked into the egr system. depends how much there is and if it still happens when hot. you would expect some amount of moisture in cold weather especially when the car is cold but if its a raging torrent all the time the car is running then that's a different matter. ide go get a pressure test done just to see if its the cooling system.

Maby its just because its winter and i have not had the magna during winter, ill pull the whole air and egr off and treat the rust and paint it, i blocked if off and have noticed less get up and go probable from the moisture.
