Hey johnny. It should be ok. Since the torque and comression of the diesel engines. Things come loose or even break. To keep the cost down. Remove one bolt at a time that holds the compressor. go get some lock tight for bolts. I forget which no# but its the blue cap I think. apply it to the threads one at time and reisntall the remained 3 bolts you should have no problems. Just make sure you get the lock tight. I use it religiously.
hope this helped.
