187inc Posted December 17, 2013 Share Posted December 17, 2013 So a car that I recently acquired (afew months ago anyway) has been dripping from the sump plug. I noticed that when I did my first oil change when I first got it that the copper washer was munted, and the sump plug seemed to be a home brew job but the thread looked good so assumed it was the washer causing the issue. Bought a new sump plug with a fancy magnet and new washer, checked the thread against the old plug, all good both OE spec, but upon cleaning around the plug hole noticed that the sump thread itself is cross-threaded. Decided out of the two plugs the new one with new washer had a better chance of sealing, but now its leaking new than it was before. So the sump thread is probably completely stuffed now im guessing. Whats the easiest way to remedy this? I'm guessing a careful tap and a larger sized sump plug? Don't want to risk getting metal shavings in the sump though.. :S Quote Link to comment Share on other sites More sharing options...
Rookie Posted December 17, 2013 Share Posted December 17, 2013 Take it off and weld a new one in? You could tap to the next size if it will take it though. Quote Link to comment Share on other sites More sharing options...
Spencer Posted December 17, 2013 Share Posted December 17, 2013 Clean it up and use some three bond. 1 Quote Link to comment Share on other sites More sharing options...

flyingbrick Posted December 17, 2013 Share Posted December 17, 2013 If its a shit car then just get some decent thread sealer and poo it all up before assembling. Quote Link to comment Share on other sites More sharing options...
187inc Posted December 17, 2013 Author Share Posted December 17, 2013 I did initially think of a helicoil but would this still leak? Car is a bit of a shitter, but of course I have a soft spot for shitters, especially ones I drive daily. Thinking ill gum it up with something and do a very careful tap further down when time allows/I can be bothered. Whats good to use in such an oily environment?

governorsam Posted December 17, 2013 Share Posted December 17, 2013 whatever you do, don't weld anything on the sump while it's in place. had a mate do this to an old holden and the oil/petrol in the sump ignited..... BOOM!!!! blew the sump to bits and sprayed hot burning oil everywhere. 1 Quote Link to comment Share on other sites More sharing options...
