Did you make it home? How much fuel did it use in a 5k mile road trip? Did you dyno it?

made it home last night at midnight after driving 4 hours in intense fog through the Adirondacks, no dyno, we decided to head out of vegas sunday and get to Zion to hike, so no dyno. Not sure if dyno was operational anyway, Marc said it had a bad bearing.

Came home to snow and trees down from a windstorm. Having a chainsaw/log skidding day today.

Met a ton of awesome people, saw a ton of awesome cars. I will do a better write up with pictures when I get settled back in here. What an awesome roadtrip. Met and exceeded all expectations.

Averaged about 45mpg, drove about 6000 miles, driving the majority of the time at an indicated 80-90mph. The car LOVES driving at highway speeds, in fact its happier near 100, but I tried to keep the speed reasonable.

Problems:
-heater blend door died on full heat position on the first day. That sucked, clamped heater hose with vice grips.
-brake booster developed a vacuum leak, which got worse over time. This seems to have put extra pressure into the crankcase and caused my car to poop a lot of oil into the intercooler. It got worse over time as the vac leak got worse. Either that or the turbo is leaking or my engine has mega blowby. I will drain the piping, fix the booster, add a catch can and a drain at the piping low point and try to pinpoint the oil intrusion. It sure seems like its coming from the CCV system, but its was using A LOT of oil yesterday. Its hard to imagine the vacuum pump can move enough air to carry all that oil, but maybe. Engine runs like a top, and its hard to believe it has an internal problem. Mostly I am glad it made it home. What a fun time.

Sounds like it was an awesome and successful trip! Very impressive MPG numbers as well.

As for the blow by/oil consumption. I don't know much about the vacuum pump setup on those engines, but I do know that when 12v/24v Cummins' have vacuum leaks the vacuum pump can pump enough air into the crankcase to make excessive blow by that would indicate a worn out engine. Cummins engines just have a blow by tube that goes to atmosphere though, so you don't see the build up in the intake system like you are seeing.

awesome pics alex! great to meet you too. Glad your trip was also a success.

Finally got the car back in action, and switched to winter mode. Switched out the springs for a new set of H&R springs. Built a new air intake setup. Added a Mann Provent 200 catch can. Added a low point 1/4 turn ball valve in the lower boost pipe to test if any oil is collecting in there and drain as required.

Drove it around on the snowy dirt roads last night, shit i forgot how much fun these cars are. The diesel requires some clutch abuse to keep it sideways because the power band is pretty narrow, but it sure is fun.

Looks like my vacuum leak at my brake booster was the cause of all my oil issues. Crazy. I am getting zero oil out of the vent with the vac system capped off, and zero oil in the intercooler after a 30 mile beat.

Here are some crappy pics of the intake I came up with. This box still uses the factory air ducting that brings air in from around the headlight, so it shouldn't suck only hot air. This little holset sounds sweet too, its pretty funnny to be hooning around in the snow with turbo spool noises, turbo stall noises and black smoke everywhere.

god this car is more fun simply because of all the funny turbo noise! I was drifting around and having a blast over the mountain today and the turbo stalling and whistling sounds so funny. Surprised how much noise this little thing makes. I really liked having a stock airbox, but I can tell it was restricting things now that its gone.

those of you who know the App Gap, it has been PRIME this week for playing on the commute. Problem is I cant drive those crazy corners at the speeds I need to for appropriate rally action and hold a phone. I stopped in one of the pulloffs to play, but it was very bumpy and not really any good. Basically this is only a sound clip from putting around in second gear. This car does the Scandinavian flick so well with the smaller engine and the big rear swaybar! I need to get a passenger and film a good run over the gap at some point.

winter mode fully engaged. She started right up at -15F this morning. No problem. Heater fan is howling, so that needs replacement.

Damn I love an old quattro in the snow. Seat heaters on level 6, heat cranking and sideways all the way to work. So fun.

The car looks a little different than it did just a couple months ago in Vegas!

yea, 7k miles for battleborn, 1k for carlisle, 72 miles a day for commuting, a couple trips to see family over holidays. It adds up quick.

What intercooler are you using, where did you source it ?
