Superglue oil leak fix
I just read an interesting thread that discussed the use of superglue
to fix an oil leak on an airplane. (The trick was to attach a shop vac to a breather so the glue is sucked into the crack.) The previous owner of my Rabbit must have stripped the oil pan drain bolt threads, as a helicoil-type repair insert has been installed. Unfortunately, it leaks at the repair joint (the bolt seals fine though). I think I'm going to try this on my diesel Rabbit. Any reason this would be a bad idea? |

I think you will find that: 1. It will be all but impossible to get the helicoil and pan clean enough to allow superglue to adhere. 2. The glue will probably shatter at some point. I you want to try filling the gaps, consider something like a non-hardening high temperature gasket sealer after thoroughly cleaning the pan and helicoil. After all this fiddling around you may ultimately find a boneyard pan is the best way to go. |

why don't you just replace the oil pan and not waste your time. |

Superglue oil leak fix
Super glue works on a lot of rubber and plastic but it will not work on
metal. I'd use an epoxy mix. |

Then if/when that fails, if u remove tank, you can weld in a replacement plug/nut cheaply--don't hafta buy another pan. s |

Superglue oil leak fix
I learned a simulair trick from a chrysler dealer. After they installed an
oil pan gasket incorrectly where it mated to the front cover. There was a lip where the gaskets overlapped seated incorrectly allowing oil to leak out about a half a quart a day. Their trick was to put a vacuumn on the oil breather hole and clean the leak area off with contact cleaner, until spotless. And use high temp red rtv and they sucked it in with the vacuumn and shut it down and let it dry overnite. It was not leaking 6 years later. Also someone did the exact same trick on a Ford 302 rear intake gasket., using red high temp rtv. The fix is to take the intake off and put a new gasket on. it was about a $500 fix. It was much more difficult to clean, but lasted about a year and a half. Also I guarantee that superglue on an aircraft engine is NOT approved by the FAA. General Aviation owners are much more lenient about their repairs , and I,m sure everything has been tried to save a buck , by people who can't afford proper maintenance. Will it work , sometimes. Would I want to fly across water about 3 hours with it. No. > wrote in message oups.com... > > why don't you just replace the oil pan and not waste your time. > |

Superglue oil leak fix
Superglue works on anything not porous like plastic, glass, and certain
rubber. If air can get to it through the material being glued, it will not work.

If the gap is so big that capillary action alone won't pull the super glue in where you want it, then the gap's too big to use super glue to repair. I agree, JB Weld is a better idea for this application. |
