CAC Oil Leak

I took my 6.0 to the dealer -3yrs old 20,000 miles Runs great. Oil was leaking down along the block over the starter with a small drip on the fly wheel housing. Oil was in the galley under the turbo.
Not a gusher but wet and noticeable.

Dealer cleaned the oil out of the galley and the block, put in dye, Cleaned the CAC tube at the turbo. Tightened to spec ? Drove it 80 miles.
No leak found with the dye.
Dealer analysis - oil leak from CAC tube at the turbo. Normal.

I DO know all the CAC tubes will be wet with some oil seepage, I do clean them off from time to time and check torqued. None are showing a drip leak. I have read all the current oil leak issues on the forum.

Does this all sound good?
The dealer is one of the best in East TN. I do not think they are doing the run around.

Comments? Thanks
Roger

Sorry for the post. I did not read enough. I think the CAC tube oil leak is correct, since it shows up as the NR 1 cause of oil where I had it.
The dealer said not to seal the tube to the turbo. I see others recommend I do that. What is the best sealer to use. The dealer said silicon would make the tube blow off easier.

Yes, drove it back from the shop today. 65 miles one way.. Oil leaking from the turbo CAC tube already. Some in galley under tube already. HAS to be a way to fix this with some sealer?

some oil in the cac system is normal. if u got excessive oil in there ud think that it b goin through the t/c and blowin smoke. i duno man id double check, or c if dealer will install new hose. stock clamp and hose assembly has a staple through them both to hold in place. mayb oil comin from the little staple holes......jst a thought....good luck
