| + | If you've noticed your oil cap mysteriously popping up, it could be a broken internal sleeve. \\ | ||
| + | One of the first symptoms is that the cap will not stay flush, but will protrude maybe an eighth of an inch above the tank surface. \\ | ||
| + | Eventually it will not click down in place at all. \\ | ||
| + | Take a close look just under the cap, where the plunger enters the body. \\ | ||
| + | The black sleeve protruding above the grey body (in the right side arrow in the 1st pic below) may indicate a broken sleeve. \\ | ||
| + | |||
| + | |The sleeve should be flush around the perimeter as \\ shown by the left side arrow. ((photo by JohnK of the XLFORUM http://xlforum.net/forums/showthread.php?t=1566307))|To disassemble, find the two side square tabs and \\ push each one in, and the mechanism will pop out \\ under spring pressure. ((photo by JohnK of the XLFORUM http://xlforum.net/forums/showthread.php?t=1566307))| This is what you will have, notice the ratchet spring \\ on the side, note how it fits for re-assembly later.

| + | |||
| + | Now take a look at the bottom of the 'sleeve'. \\ | ||
| + | It should be one piece. \\ | ||
| + | The two halves are held together by two very thin sections of plastic on the bottom (as in the circled areas below). \\ | ||
| + | In this case, the sleeve was broken into two pieces. \\ | ||
| + | |||
| + | The locking tabs are both on one half of the sleeve, the other side is free to slide inside the body. \\ | ||
| + | As long as the sleeve is joined together in one piece that's fine. \\ | ||
| + | But the bottom thin section is prone to cracking. \\ | ||
| + | (one side is locked and the other moves up and down ever so slightly each time the cap is popped) \\ | ||
| + | Once this fails, the 'loose' side will protrude up as seen in the first pic above. \\ | ||
| + | The side without the locking tabs is also the side with the ratchet spring. \\ | ||
| + | (which adds additional up and down drag every time the mechanism is worked, accelerating the failure) \\ | ||
| + | |||
| + | |The thin connecting material was broken out. ((photo by JohnK of the XLFORUM http://xlforum.net/forums/showthread.php?t=1566307))|Here are all the components, minus the broken out \\ pieces. The sleeve is now in two halves. ((photo by JohnK of the XLFORUM http://xlforum.net/forums/showthread.php?t=1566307))|Note the locking tabs on one half of the sleeve and \\ none on the other.

| + | |||
| + | The solution was to re-assemble the mechanism and install a set-screw to hold the loose side in place. \\ | ||
| + | |||
| + | The entire operation shouldn't take more than an hour, if you take your time. \\ | ||
| + | The only items required are a small screwdriver to push in the locking tabs, a set screw, an appropriate drill bit and drill. \\ | ||
| + | You can find a small flat head screw, countersink the hole and drive the screw head flush for a better-than original look and function. \\ | ||

| + | |||
| + | Below, a brass screw from an electrical lug was used to screw through the grey plastic body and into the black inner sleeve. \\ | ||
| + | It was short enough not to interfere with the moving plunger while long enough to screw through the grey plastic body to the sleeve. \\ | ||
| + | Find a way to hold the sleeve down flush with the outer body and drill a hole slightly smaller than the screw thread. \\ | ||
| + | Drill it right through both the body and sleeve. \\ | ||
| + | It can be done with the plunger installed but it would be better to leave it out. \\ | ||
| + | Drive the screw into the plastic, it will cut its own thread (that's why you drill a smaller pre-drill size hole). \\ | ||
| + | |||
| + | |Finished product. ((photo by JohnK of the XLFORUM http://xlforum.net/forums/showthread.php?t=1566307))|Here's what it looks like from the inside. The spot for this particle drilled hole put the screw partially in the slot, \\ which would have nullified the fix. A smarter choice would have been into one of the lugs as indicated below.
