Will the "blue" CPS work on the OBS trucks? My dad's got a 97 F-250HD 7.3L. From what we know its the original CPS. I'm planning on getting a blue one for my 01, but I'll pick up two if it'll work in his engine.

You guys should at least check the air gap on your cam sensors. .025 - .030 is the spec. There are two different size/length sensors so be sure you install teh correct length sensor. After working at international for 10 yrs I've replaced many many blue sensors in the DT and a fraction of them have been the black sensors from the T444E. We used to put the black ones in some DT's that had continuous problems with cmp noise.

"I believe the part # posted in this thread is correct and not the p/n for the wrong one."
Just saying, don't walk into an international dealer and say give me a blue cam sensor as there are several different ones.
You would have to check the clearence with a depth mic. Navistar has a very nice tool that takes all the guess work out of the job. With a depth mic., remove the sensor, install the mic into the sensor hole, and run it in until it bottoms out on a vane of the pick up wheel and read what the mic is. Then measure the flange of the sensor to the base. Subtract the two readings and you should be in the .025 - .030 range. I have found on many 444 that the air gap is to large and the front cover needs to be sanded/ground down a bit to put the clearence back into spec. I've seen the sensors working but cutting out intermittantly with air gaps of .050", ground the cover and reinstalled the sensor and never had a problem since.
