[FC] Leak from Base of FC Oil Fill Tube

[Ken Hand]

      The best way to accomplish this is to raise the passenger side of the vehicle quite high. Remove the bolt in the sheetmetal where the tube goes through the upper sheet metal. then twist the tube and pull at the same time and, PRESTO/CHANGEO, you have a tube in your hand. 

     With the FC up on that side you shouldn't loose any oil, I guess if you want to be sure, you could drain the oil, but I don't think that is needed if you don't want to. Then wipe any dirt from the area where the o-ring goes in the block and lube the lip with some lube of some kind, I prefer silicone grease, then install the new o-ring on the tube after clean-up and a little more silicone grease and reverse procedure to reinstall.

Subject: [FC] Leak from Base of FC Oil Fill Tube










I've noticed a leak source with the wife's Greenbrier where the oil  fill 
tube enters the engine block. It's not a huge leak, but annoying enough to  want 

to fix (so I won't have to listen to the wife say, every other  day: " I guess 
we're never going to have an oil-free driveway."    The assembly manual 
clearly shows an o-ring for the base of the tube (GM PN:  3777504), and Clark's 
lists a viton replacement. I cannot remember what o-ring 
I  used when rebuilding 

years ago; but, apparently, whatever I used has given up.  Having identified 
the issue, can the tube be removed and reinstalled with the  engine in the 
vehicle? If so, can someone who has performed  this operation please advise best 

method.
 
Thank you,
