no was just asking if it was a visual thing or not. have turbo off and #7 injector out for replacement pulled EGR valve to inspect and clean and was looking at the cooler. no loss of coolant yet no smoke other than black created by bad injector. going through the normal stuff on this 6.0 to get it running good again. did the FICM repair yesterday that REALLY helped alot. Just trying to check everything while i got it apart. thanks Joe
