powerstroke concern.

[bobby rfpjr]

Hey everyone. I'm new to the site and was wanting some help with a concern I have had since I have had my truck. Well for starters its a 1997 f250 2wd 7.3 powerstroke with the 5spd it has 187,000 miles on it. The truck is stock other than straight piped exhaust. I have had the truck for 3 years and have wanted a chip for it from day one, but the guys at the local ford place said that if I chip it and turn it hard that it wild make the cam walk either away from the cps or towards it and cause it not to run. And then I would need a new engine. Is this true? Thanks in advance for any input.

Not true, you sent me a message already lol, welcome to the org, custom or canned tunes are your friend, the cps (cam position sensor) is one of those regular things that goes out often, just keep a spare its like $20 each, and 2 10mm bolts, it won't go out kause of a tune, your truck would actually benefit from some tunes, I get better fuel economy by atleast 4-5 mpg's. Good luck and enjoy your self a bit, where you located BTW?

I've been frequenting various Powerstroke forums for over 12 years now and that's a new one! Yoy will have no problems with the cam using a chip (that's what the thrust bearings are for). Cheers!

Some early PSDs had alleged "cam walk." If there was an issue with the CPS hitting the cam gear, the CPS was shimmed away from the timing cover. The cam is retained by a thrust plate and should be within spec unless nasty things went on inside the engine. Some higher power trucks with hybrid injectors have had the cam gear pull off the cam (since it is a press fit with a key.)

Well I figured they were shooting me a load a crap. Those guys at wallace n.c. ford dealership are *** holes any ways. Thanks for your help guys. I feel a lot better now about trying to mod my truck.

There were some issues with some cam thrust, but I don't remember it being very common (very very few posts on that issue). It was the early CPSs that were fussy on the "air gap" and required the shims to get it correct (it wasn't because of the cam "walking". That's why the newer (back then) were considered shimless. Cheers!

you'll be fine. there's a reason that so many guys have chips on these trucks. if there was an issue like that, there wouldn't be near the number of modded trucks out there that there is. welcome to the org!
