I bet its your plastic piping going bad. The plastic y-pipe is known to leak. Replace the clamps while you are at it.

Check the out put port of the secondary turbo. Make sure the flange nuts are tight. It is hard to see from above because the secondary turbo intake pipe lays over top of it.
Also check to see if your y-pipe o-ring seal is bad. There is a coupling point in the back half of the y-pipe that requires a rubber o-ring to properly seal. You will probably need to pull the y-pipe out and separate it to see.

You would have introduced WATER right into your intake tract while not under positive pressure. No folks, this is not how aquamist works, but this is how hydrolock works - pistons or not.

Standard place is the x-over pipe (black or silver plastic) comiong out of the turbos which eventually goes into the intercooler. Look at the 90 degree bend portion where it clamps (right of the black vaccum chamber).

I actually think the probability is great that you will find the leak in one of the hoses that connects to the blow off valves. But someone else has already suggested that and I am merely offering another possibility if those hoses prove to be intact.
Not to brag, but I have had two FDs, driven 207,000 miles combined, so I have experienced all of the problems that have been described by others in this thread. Some are hard to find, but you certainly have some place where the boost is escaping to the atmosphere--either a split hose or a loose connection. Just keep looking. You'll probably go 'dah' when you find it. Good luck!

just wondering, but if the CRV (i think thats what its called)or the BOV that controlles that 2nd is split then would that affect the primary turbo?
