Sump plug removal

17 posts in this topic

Trying to do a 'quick' oil change... :(

Warmed it up, up on the ramps, sump plug welded to the oil pan.

I've soaked it in some plus gas but worried I'll continue to round the shoulders off the plug.

Do I persevere or give it up for the MRG boys?

How hard is it to get a rounded off sump plug out?

Being honest with you man this is a pig of a moment. It happened on my spacewagon so in the end i gave up and got a pump to take out the oil and i must admit its the best tool i ever bought. Did the volvo oil change yesterday with it at was so quick and easy.

If you think your going to round it off then leave it for the MRG Guys and get a new one fitted! As Mr Scott said "The right tool for the right Job"

Hi Red Brick

Just a question was the sump plug already damaged? or not? Shirley a garage would not leave something so simple as this in such a bad sate or miss a thing in a general health check of a car?

Just a question?

Try give it a bang with a hammer ' not too hard though' then try again if that fails get someone with a mig welder to spot weld a bigger nut to it :)

Spray like buggery with WD40 - Give it a good few solid taps with a hammer - then spray again with WD40, leave half hour, spray again, whack again, then try again.

As Shem says, Single hex socket :)

IF it does indeed lock, round or whatever, it ain't the end of the world - you just need to use a reverse thread socket ;)

:stupid: not really the kinda thing u can get the burner on either as you will boil all the oil in the sump that makes abit of mess and stinks too

it will normally go but will be very tight it wont be that its been torque'd up mega tight they just seem to grip really well as soon as it cracks off it should be able to unscrew by hand

decent fitting ring spanner and a lump hammer might just shock it off

if you have a good one yeah cheap impact drivers seem to never work properly in my experience if you have some impact sockets there single hex

another problem is its a ver shallow bolt head and if you look at most sockets there shamferred inwards so your probly only gripping the very edge of the bolt head i have ground sockets down before so that it will sit completely over the bolt.

Is that like a glass hammer? lol

I've given up and just taken her for a good drive. I'm due in MRG tomorrow anyway for tracking so I'll ask them to break the seal.

I'll get a 17mm single hex socket as you have suggested for the future.

Cheers All :D

Youd do well to boil 6l of oil with a torch imo. As the oil is behind it, heat wont do much. Whatever you do, Id get another sump plug ready as you wont go far without one!

Ah, then unleash hell. I always use a ring spanner, but also got a windy hammer with hex sockets.. If youve got the tools give it a go, or like you say, a garage should help.
