The rave says to remove the O2 sensors with a 22mm crows foot. I don't have a crows foot wrench and I can't get my 22mm open end on the sensor because of engine and frame rail interference.

What's the easiest way to get the old one out and new one in?

I've only done the drivers side on the D2.

Did the pb blaster/heat cycle thing a couple times with no luck.

I ended up chopping the sensor guts off, then using an impact socket and breaker bar with a 2' tree of wobble extensions inbetween such that the breaker sticks out the top of the engine bay.

Then I smashed my fingers into the fender when it finally broke loose.

It sucked.

Putting the new one in is pretty easy though

 

Well you made me laugh!

If it makes you feel any better, when I was torquing the head bolts on my last Disco, the torque wrench slipped off one bolt when I was trying to get that sucker clocked,............I smashed my thumbnail which started forming a blood blister (Hematoma?) under the nail fairly quickly.

About 3 AM the next morning, my throbbing thumb woke me up,.......The blood blister had gotten bigger. I went on the interenet to find out what to do. Two DIY solutions were to heat up a paper clip until red hot and burn a hole in the nail,....tried that..............YOWWWW! So,.....went to plan B and got a small drill bit and wrapped some adhesive tape around the end that normally goes in the drill,.....I rolled it back and forth between my thumb and fore finger, and I was surprised how quickly it drilled a hole through the nail. Had a spurt of blood when the drill bit went through. The nail did turn black and die,....and it took a year to grow out. Two years later,.......(today) its still not right.
