Throttle body air leak...Pics inside with how to fix!!!
Did this today with 13-0 and the car drives like a new evo again. What I mean is that the irritating jerkiness at parking lot speeds has smoothed out incredibly. I had about 300lbs of tools in the car on the way back home so I really didn't get on it much but it does spool faster and has a sensation of more immediate boost.
On another related note I believe I let the car cool down for too long because with the boost leak tester at the throttle body I would loose boost, not as qucikly as before the seal install mind you. We could actually hear the air moving past the piston rings when listening through the oil inlet on the valve cover. Anyone else have this happen when trying to pressurize the system?

We got confirmation recently that these seals DO fit perfectly into the Evo throttle body. Honestly, I'm surprised that cars this new are having problems with this. I don't remember any DSM's with leaky throttle bodies at three years old. At least it's relatively inexpensive to fix.
I've added the seals to our Evo web site, so hopefully you can add a T-shirt or another Evo trinket to your order and amortize the shipping over a couple of items.
As always, thanks for your business.

Damn MachV, what up with that $10 shipping charge on the seals! You could just put them in a regular envelop and ship them for $0.39!!!!
We're flexible, though: We can send them United States Postal Service for $1. Just write that in the "Comments" section of your order. Keep in mind, though, that USPS has NO tracking number, and if it's lost or damaged...you'll just have to order them again.

Also just had to have my idle reset with a MUt-II scanner. Apparently the seals were so bad that it threw everything out of calibration. I was getting a DTC P0507: Idle Control System RPM Higher Than Expected code after replacing my t/b seals. Car is a dream to drive. Idle is very consistent and no longer bogs low when coming to stop with a/c on. I just wonder if the failure of these seals contributed to the failure of my idle air controller...

I do like the fact that these replacement seals have a metal ring surrounded by the rubber seal material as opposed to the stock seals which have the metal ring on the outer face. Seems as though the 3390's will just give us a better all around seal.
