O2 Sensor Unplugged Question
91 F-250, 5.8 I have replaced engine and went with long tube headers and there is no way to install O2 sensor in header (thanks Pacesetter, total disappointment with fitment) so I am going to have it put into exhaust pipe back about same location it was in stock pipe. My question is can I run engine to get everything set and ready to go to exhaust shop without the O2 sensor being hooked up without hurting anything. I may drive truck to shop also if I can about 20 miles if that would be possible. Yes I know it will be loud, I live out in the middle of no where and know most of the lawmen so that's not a problem. Also is it OK to have in just one pipe(going to be dual all the way back) or should I put in an "H" pipe as the factory did and put sensor in "H" pipe?
As for Pacesetter headers, drivers side is hitting front drive shaft so gonna have to bend whole header some how, passenger side hitting frame so gonna have to put small notch in frame. Everything I heard on Pacesetter was how great they fit...I am not impressed one bit....

Minor frame clearancing on the passenger side isn't uncommon, had to do it on my F150s with Flowtech headers.

What is the problem there.. wrong angle and/or interference with something?
Cannot fit sensor between header and trans(E4OD)...was going to be able to make it work on drivers side until I realized header was hitting driveshaft and will have to bend complete header towards trans so that is out.
Put it as close to the engine as possible, in the header collector works well.
will do
Yes no problem.
excellent
Yes works fine.
again excellent
Is this an F250 maybe or something with a solid axle? Most(if not all) longtube headers made for this vintage trucks are designed around the TTB front axle which has more driveshaft clearance
yes F-250, no straight axle it is TTB, it is bone stock I know for sure.
Minor frame clearancing on the passenger side isn't uncommon, had to do it on my F150s with Flowtech headers.
yes I have no problem with frame notching I have done this on many occasions, I have notched many of frames for this reason, it's just everyone bragged about how good these headers fit and they hit everything in there path. just disappointed but it will all be ok....thanks for the help Conanski once again you have the answers that please me.
