DuraRaj 04-05-2008, 03:09 AM Took my truck in to dealer for some warranty work and to check on oil weep around the intercooler intake area. Tech informed me that according to GM it is a normal condition. Oil is caused by Compressor seal leak.:eek: What do you guys think? TSB(?) attached. fire0021 04-05-2008, 04:43 AM if its the intercooler pipe pasanger side down low then know there wrong there is a missing o ring tht goes in there wich is causing a huge boost leak as well Diesel52 04-05-2008, 10:24 AM It is funny operating hiway or off hiway trucks their turbos don't weap unless they have alot of miles on them. If this weaping is normal then they sure have lowered the standards for public equipment. Even that 769 rock truck that had a warnout engine ( consumed full to way below low in 6 hours of operation) the turbo wasn't weaping on it.

I'll be looking and be putting an O Ring if it's missing one. Thanks! DuraRaj 04-05-2008, 01:51 PM lot of people have been venting the pcv to under their trucks to get rid of this problem Ill try that and see if it works. Thanks for all your help. huthuthut 04-05-2008, 01:54 PM x2, PCV reroute and cleaning of all intake tubes and boots by removing them and reinstalling will solve it. Arkapigdiesel 04-05-2008, 02:10 PM lot of people have been venting the pcv to under their trucks to get rid of this problem Yep. I did mine within of having my truck for the first 5K miles.

I have or had (apparently they fixed it....we'll see) the oil "weep". I am running around 8-9 psi when crusing the highway at 73 mph is that about right? JimmyDel 05-13-2008, 03:35 PM The leak is on the low pressure side of the turbo so no need to worry about a boost leak. Rcannon 05-13-2008, 05:26 PM Yep.
