To all who replied, thanks.
The reason for my query, is an observation of the hoses that I have in service on one of my CRD's. I have two CRD's, each with ID hoses installed. The one that is displaying this unusual tendency, has approx. two years and 70000 mi. on the hose set.
This description of the observation sounds a bit strange, but I really do not know another way to put it. Both charge hoses will be completely covered with a very thin film of what appears to be engine oil, but nothing else in the engine compartment displays this, somewhat eliminating an external leak. It appears that the CAC hoses are sweating engine oil. I have removed and completely cleaned and inspected them two or three times, found no damage, reinstalled to find the oil film reappear a week or two later. Almost like the carry over oil from the CCV is permeating the hose slowly.
Now, operationally, this vehicle makes two, 5-6 hour trips per week, at a sustained 75-80mph speed, without being shut down, plus normal local trips during the week. So, the CAC hoses are seeing 14-15psi boost pressure continually during this time. just curious if anyone else has observed this, and it seemed to coincide with the hoses no longer appearing in the catalog.
I am aware of the Provent option, there is not one installed currently, but may be in the future. However, the issue I am questioning is whether or not the hoses are bleeding slowly, be it oil or air.
