How Many Under-tightened Diesel Intake Clamps

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.

Guess I could check these when I get home.

But I'll probably just forget.

Oh look at that, I forgot to check. :laugh:

Guess I'll have to put a reminder in my phone.

I wouldn't say any were really something I'd consider "loose", but two were able to be tightened - the two nearest the airbox. The second one in allowed more turns and was the "looser" of the two - but neither were going anywhere.

T-bolt band clamps might work better, than the worm-gear style.

I just got about a 1/4 turn on most of the clamps when I checked yesterday afternoon (while the engine was still hot).

Is there clearance to replace the intercooler to throttle body tubing with metal tubing and silicone couplers?
