admin Posted October 10, 2012 Report Share Posted October 10, 2012 Got my 4.2 serviced today (Manuel) and I asked them to empty the gear box oil and replace with supplied vmx80 as I think it will help with the notchy gearbox, but when I got the car back I was told they couldn't get the plug out. They say they swung off a 6ft bar and it still wouldn't budge. They tried heat to.. No go. Basically they gave up and said to take it to Nissan. :-( Anyone else have this happen?

BigGQWesty Posted October 10, 2012 Report Share Posted October 10, 2012 Weird.. I don't think they would have tried a 6' bar.. If they did they must be a little limp. Grab a good punch and place it inside the plug notch.. Give it a good crack with a hammer, then try undoing it.. Heating the plug would make the problem worse, you want to contract the plug, not expand it. Crab a can of crc freeze and try it. It'll come out, it depends on how hard you wanna try...

Rumcajs Posted October 10, 2012 Report Share Posted October 10, 2012 (edited) The plug is tapered so if it was overtightened the result is what you are now experiencing. Very common may I add. Try what is suggested above but within a reason you don't wanna crack the gearbox housing. I wouldn't use the punch just use square end of a drive which fits, smack it with a hammer it will be kinda like an impact driver.
