you need to replace all old hoses and CAC boots that look old .. check all piping on intake for rust and flaking on insides.. check any blocked off cisrcuits, replace the air dryer unit and fix all air leaks.

you also need to ensure you do not have excessive blo-by and that there is no pressure building in the crank case.

All I could find was 2-4” boots in the area where I’m at.Got a new intake hose for the compressor.How do I check if there is air building up in the crankcase? Truck still has EGR.

by checking to see how much blo-by you ave and ensure the breather tube is not blocked up.
