Today was supposed to be engine re-installation day (after 3 years of body/paint work). Just need to situate the jack under the pan of the installed 904 A/T to move it up/down to match up with the V-8. We'll be done in no time. About three years old now, Duralast floor jack will not attain full extension. Drag jack back out from under vehicle. I follow air purge instructions on label: Turn handle two revolutions counter-clockwise. Pump handle quickly 6-8 times. With a screwdriver, push rubber fill plug over to the side to let trapped air escape. Whoosh! Done? Nope. Close valve and pump handle to test improved performance. Hydraulic oil oozing and gurgling from center of rubber fill plug. Fill plug no longer air tight. Just the slight nudge with a screwdriver tore it up. Pry out fill plug with small screwdriver. Top half of plug separates from bottom half of plug. Pry out bottom of trapped fill plug? Nope, it falls inside the abyss. Why not use a screw instead of a rubber fill plug that rots and becomes unserviceable in no time? Chinese torture, that's why. Crap like this is why I have decided not to restore our rusty third classic Moper in the waiting. This chinese crap is taking all the fun out of it. Edit: I found an 8mm plug (pinkish in color) in my stash of nuts/bolt/misc. which fit the fill hole and got things going again without having to shop around endlessly.
