How Many Under-tightened Diesel Intake Clamps

50701 91
On the intake of the Diesel, there are 5 hose clamps holding together the various pieces between the air filter and the entrance to the turbo. These are the type that use a flat head screw to tighten them around the tube. When I checked mine tonight while changing my air filters, I discovered that 3 of the 5 were under-tightened--two of them so loose I could turn the screws by hand without a screwdriver. As un-metered air entering the intake has been proposed as a contributing factor to the sensor failures that some of us have experienced, this is something we should all probably check, along with visually inspecting for areas that could be drawing air. I would like as many Diesel owners as possible to check their hose clamps and report in the poll above how many were under-tightened. If you had any under-tightened clamps, post the age and mileage of your vehicle below. (2 years, 46,000 miles for me.

T-bolt band clamps might work better, than the worm-gear style.
Egg-zactly. The Cummins in my Ram had all sorts of high grade fasteners such as T-bolt bands with nyloks, which never came loose. I think I'll look around for some that might fit.

Also, unlike the CTD, the pressurized intake section was high grade stuff.

I put a bit of blue Loctite on the the band for now. Anybody tried that?

I last checked them at 19000 miles and one or two were a little loose. I put some blue loctite on the threaded part on all five clamps. Today, at 27,000 miles, all five are still tight. Not sure if the loctite had anything to do with it, though.
