Coolant Leak 07 speed3

[2007speed3]

Have a small coolant leak that I cannot locate exact source (of course it is underneath the CAI and turbo inlet valve. Car doesn't overheat, has 60K miles and I track/HPDE. Brought to dealer did pressure check and it passed. They put rad die in the coolant and still could not locate source after a few days of driving. There are stains under the area near the EGR on the block. I paid for EGR valve and gasket replacement but the leak came back later (not under warranty!) Went back to dealer and they replaced under warranty the oil pipe gasket, water inlet mount gasket and another gasket. I have checked all the hoses, bolts and replaced some of the clamps. I seems to hesitate a little and only leak when I push close to red line and the engine is hot. Since I want to start going to the track soon, I want to make sure this is not serious. If it was the turbo inlet hose, I would think it would fail the pressure test. Does any one have other suggestions or know a great mechanic in the DC area?

i think i know what you are talking about. did you by any chance happen to have your tip removed or replaced recently?

Yes, have had turbo inlet pipe off to look for the leak, but originally it was to replace OEM with the COBB TIP.

lol...replace the coolant return hose and make sure all the clamps are tight.

Fixed It

It was just the OEM hose clamp not holding under high pressure. I replaced it with a good hose clamp.
