Best way to Compression Test the cylinders
#51
OK, while trying to get my o2 sensors off I noticed something!! What appear to be breather tubes just dangling.. I pulled the hooked end up in to the engine compartment to see if there was any obvious connection, this is NOT the axle breather tube. Then went underneath and found the other end of one, which reaches the xfer case, isn't even plugged in. Does anyone know what these are for? They don't seem to match up to the EVAP system:
I pulled this one down, it in between the tranny and front driveshaft connection at the xfer case.
Right above the o2 sensor passenger side:

I tried two different O2 sensor sockets on mine when I did them ~40k ago and couldn't get enough leverage without the sockets starting to slip over the hex on the sensors. This was after I had been soaking them for days with PB Blaster. I finally cut off the connector and slipped the box end of a combi wrench over it so I could double up on the wrenches for more leverage. Finally broke them free. Antiseized the crap out of the new ones. With the open end of a combi, you only have 2 flats against the sensor...

The breather tube for the transfer case connects on the top of it. There is a banjo bolt up there, the tube connects to a collar, the bolt goes through the collar. Like someone already said, those tubes wouldn't be the cause of your engine problems but they are still important to keep connected and cleared out. In high water/mud sucking that into a diff, T-Case or Transmission could be costly.
