The PLASTIC handle of the dipstick in my wife's 2005 Nissan Sentra has been broken for about a year or so now. Now why anybody in their right might, let alone a REAL "Engineer", would design this part with a 100%, NON-reinforced plastic handle is beyond me. The kind of plastic they use has been breaking more or less continuously since around 1998, and you'd have to be a real ding-dong to not change it.
It's been more of an annoyance than anything because I've had to use a pair of needle nose pliers to pull it out and check the oil, but in that category of "This'll work until I buy a replacement part", so we both kinda let it slide. I finally bought a new dipstick the other day, and figured while it was still light out, I'd pop the hood and install the new one.
It appears that the last time she had the oil changed, the moron who works there didn't realize the plastic handle of the stick was broken off, thought the dipstick was already out of the engine, and tried to jam another dipstick on top of it to 'check the oil'.
The previously reachable (broken) stick is now about 4~6" down inside the dipstick tube, and is barely visible, let alone grabbable.
Every little tool I have that might be able to reach down the tube and snag the stick just doesn't work.
I tried putting some Super Glue on the end of a chopstick, but the plastic is just too oily for the glue to hold.
One 'solution' I saw posted in a Nissan forum was to pressurize the crankcase with compressed air, which supposedly blows the stick out of the tube. I'll try that tomorrow, but I think this one's been stuffed down the tube too far to come back out with just a few p.s.i. of air, so I'm resigned to having to (carefully!) twist the dipstick tube out of the block, remove the dipstick, and then tap the tube back in.
That involves removing the heat shield over the exhaust manifold, a job best done after the car has sat over night.
I've read where they make an all-metal replacement dipstick, so that's next on the search list!
