clint80 Posted May 26, 2010 Share Posted May 26, 2010 i got my first 6.7 mil on 174 miles, code P0299. there is a ssm out already for this concern. ssm 21305 P0299 mil on vehicles built before 04/05/2010. " May be due to an incorrectly adjusted turbo wastegate actuator. Prior to performing normal diagnostics, check turbo wastegate adjustment." i perf the wastegate adjustment check and it was way out of spec, opening at 5 inches of vac. spec is to see rod moving with vac applied between 8.3 -10 inches. the paint mark was still intact on the rod. I had to remove wastegate and rotate counterclockwise 4 times to get into spec. Waiting for intake gaskets to recheck and drive tommorrow. The upper intake came out fairly easy I wonder why it was so out of spec from the factory? Quote Link to comment Share on other sites More sharing options...
Aaron Posted May 27, 2010 Share Posted May 27, 2010 Guy that was supposed to set them up that day was on coffee break, so the next guy down the line just slammed 'em on anyhow. Quote Link to comment Share on other sites More sharing options...
Keith Browning Posted May 27, 2010 Share Posted May 27, 2010 I didn't think this was gonna be an easy adjustment. Quote Link to comment Share on other sites More sharing options...
clint80 Posted May 27, 2010 Author Share Posted May 27, 2010 So I put the intake back on, cleared the code and drove the truck today. p0299 has not returned yet, but it still feels like it has a lack of boost. My map pid showed 33 psi max at wot, which would be about 19 mgp psi. I have in my notes from 6.7 class normal boost is between 26-28 psi. kind of sounds like a cac leak while I am accelorating, but I havnt done any diag besides the ssm yet. we'll see what we find tomorrow.

clint80 Posted May 27, 2010 Author Share Posted May 27, 2010 smoke tested intake today and found cac hose connection from turbo leaking. this is a quick connect like the 6.4 rad hoses. I pulled it off and no o-ring is to be found. A metal to metal connection did seal good enough to make 20 psi though Quote Link to comment Share on other sites More sharing options...
Aaron Posted May 28, 2010 Share Posted May 28, 2010 Hmm...interesting...the two 6.7 trucks I have driven have only made ~20-24psi of boost, but there has been no audible boost leaks or P0299. Quote Link to comment Share on other sites More sharing options...
joshbuys Posted May 28, 2010 Share Posted May 28, 2010 Hmm...interesting...the two 6.7 trucks I have driven have only made ~20-24psi of boost, but there has been no audible boost leaks or P0299. +1, I've PDI'd a pickup and two chassis cabs and all were just over 20 psi with no codes/noise.

clint80 Posted May 28, 2010 Author Share Posted May 28, 2010 i forgot to mention that there was also a code pending before I smoke tested it this morning. p0299 didnt come back, but there was a p02ec(high air flow detected) stored. Its hard to believe that I have 2 problems with this new truck, but I have been very thourogh with my diag_this being my first 6.7 diag. I set the wastegate rod adjustment to 9.5 inches-which I just noticed this is the number marked on the wastegate in the coffee table book. I pulled the cac hose off of another 6.7 on the lot and the o-ring is in there. I also took this stock unit and made a recording of the map pid, and got 22 psi as my max boost. It is a little difficult getting the cac quick release loose. I used 2 long flatblades and a long booger picker. here are some pics of the quick connect. The second picture is where the o-ring is missing from the metal sleeve. Quote Link to comment Share on other sites More sharing options...

clint80 Posted June 1, 2010 Author Share Posted June 1, 2010 I put the new cac hose on today, drove veh 20 miles, no more codes. truck now makes 24 psi boost. All is well now. here is a pic of the new cac with the o-ring. theres not much to it, its a thin sharp edged o-ring. Quote Link to comment Share on other sites More sharing options...
Keith Browning Posted June 1, 2010 Share Posted June 1, 2010 Thank you for sharing Clint. The pics always help too. A quick glance at one of these CAC tubes and you could miss the seal if you aren't looking. I am guessing there is no such thing as a replacement o-ring? Seems a waste to have to replace the entire tube for a missing seal... kinda like the hose clips on the 6.4L. Quote Link to comment Share on other sites More sharing options...
mchan68 Posted June 2, 2010 Share Posted June 2, 2010 I'm sure it HAS to become available at some point in time. Quote Link to comment Share on other sites More sharing options...
clint80 Posted June 2, 2010 Author Share Posted June 2, 2010 I contacted hotline and so far the only way to get the seal is with the tube. They did however tell me that this seal is reusable. Quote Link to comment Share on other sites More sharing options...
