Is Ryan a member here? When did this happen and how was it handled?

Yea that's me. Fully built block with Comp bp kit. When everything was done, started the car, everything was good for about 10 min, then I noticed a slow drip of coolant from the exhaust. Started checking everything I could, made sure to verify it wasn't coming from the engine since I just built it. After removing the turbo and removing the housings, I found the turbo housing soaked with coolant. Turbo manifold was dry, indicating turbo seal coolant leak. Sent back to comp, they replaced the entire center section, and had it back within a few days. Comp was actually a pleasure to deal with, and they corrected the problem quickly, and correctly free of charge with free return shipping.

Since this failure, I have put about 1000 miles on the car with absolutely no problems. These turbos are fairly new, maybe its a quality control issue, maybe its a poor design, I am not sure. But I can tell you, they will warranty it for you, and everything is running perfectly since being replaced. I will be greasing mine every 2000 miles or so, personally think that is the longest that should be gone.

Call Comp directly and get it handled. The guy I dealt with was Joe.

I think you can still get the oil cooled turbos.

Did you check it for shaft play? That would sound like a siren or warble. When you clock the turbo the only thing that moves is the housing the compressor wheel does'nt move and slides over the turbine wheel shaft. The only bolt that comes off is the one that holds the compressor on and it could be loose but other than that bearing failure? I'd take detailed pics for Sasha and for Comp Turbo then pull the housing to see what happened. But wait till you talk to Comp before doing that.

BINGO it started to sound like a siren in the distance exactly. I haven't checked anything yet just pulled the turbo out for pics.

I loosen the downpipe and rotated it off the bottom of the floor late last night ....took car out this morning ran about 150 miles normal driving ..boost set at 7 lbs ..everything runs/sounds fine. You can hear the turbo spool/howl spools up smooth and spools down smooth...boost comes on very fast and strong and you can hear the turbo spool down after shutting car off ..not loud just a smooth spool down for a good 20 seconds so I would assume the blades isn't hitting or dragging anything.

Im sure you're fine. It would most likely not be running smoothly into boost if your turbo looked like mine. These little Bluetooth inspection camera/scopes come in handy instead of taking stuff apart....i think i got mine for 50-60 bucks. https://goo.gl/images/itKjdU

I got one of these from Amazon. 20 bucks. It's a bit of a hassle to get it to work with a computer. Once you figure it out. It works great.

This is just great. There is threads about these and other failures on the SVT, Viper and Audi forums. I'm almost done installing mine as well. Crossing fingers!!

I think those reviews were for the first version, correct? They didn't have the grease fitting. The grease fitting was supposed to fix everything.

Damn!! Well there's still the Precision 62/64/6766 options. I was wanting to bump to 6766 from my 6266 but after some reading I'm digging the 6466. For those who went oiless the install and routing of the exapump is no worse than doing an oil cooler install.
