    working on a E47 that had one of two filter/drain plugs stripped out. Tried to JB weld it back on.....too much pressure or wasn't strong enough bond?? cleaned everthing with brake cleaner before applying.

    Do you think it would be OK to tack weld this fitting? if not what would i be ruining? Didn't know if when i grounded the pump it would ruin any of the elecrical components??

    Why not rethread it to the next bigger size or helicoil it?

    the sump assembly is aluminuim, sorry can't spell. Welding would work but don't ever try to change you filter, which needs to be done. Plus, not that easy welding aluminum to steel, which most of the plugs are. the sump base is easy to tap out to the next size up, either replace the sump base or tap it out. If you tap it out be sure that the tap goes in stright or it will leak, you will also have to be sure to get all the cuttings out or they will cause havoic with in the pump. Mike

    Sorry you cannot weld aluminum to steel with conventional commercial TIG welders. The aluminum can be welded with an aluminum threaded bung but try going one larger in the next NPT family.
