Removing stuck sump plug.

[Uber_Matt]

This morning i took a trip to supercheap and bought 5l of HPR30, a filter and an oil drain bucket + funnel.

Upon returning home i put the bucket under my car (92 VP 3.8L) and tried to undo the sump plug. It wouldnt budge. I thought maybe its left hand thread, nope, still didnt budge. I saturated it in RP7 and left it for 20mins, nope, still stuck. I tapped it with a hammer and then tried to undo it, nope, still stuck. I have been trying since 11am this morning to undo this damn thing and i cant do it! :cry:

Does anybody have any ideas as to how i could get this damn thing off? It would VERY much be appreciated.


Matt.

yank on it harder, or use a longer spanner, or breaker bar. Make sure your turning it to the left (anticlockwise) ... righty tighty, lefty loosey :dodgy:

Use a longer one, if you have one.. Best advice..

Use your whole body, like you're rowing.. That often works..

Im not particularly keen on yanking on it any harder, i dont want to strip it. From the position i am lying in to reach it, left would be clockwise anyway, not anticlockwise.

 

[Shounak]

Is it slipping when you yank it? If so, then it will probably strip it.. Otherwise, go for it..

Well i cant feel any slippage when im yanking on it, it jsut doesnt move. Its hard to get any leverage whilst lying on your back too. I might give it another go tomorrow arvo, i have to go to work in 2mins anyway.

i had the same prob, i just used a hammer and chisel, i kept shocking it till it started turning, then i just threw the spanner on it and come of with ease

If you don't mind running the risk of blowing yourself up, heating it up with an oxy torch would loosen it a bit. Or if you don't feel like doing that, if you've got any way of cooling it right down (got any dry ice kicking around?), the contraction due to the cold is normally enough to just 'break' whatever is holding it in.

Of course there's nothing like a 3ft lenth of steel pipe on the end of a bar to help undo it! That would be my first choice.
