Rounded Sump Bolt

Post by **Turbokomet** » 27 Oct 2006, 15:38

I Have decided to change the oil etc on my van.

1st job undo sump bolt.... bolt rounded off

can go no further.

Has been done up really and i mean really tight.

Have plus gassed it and am waiting.

Anybody got an idea if I can get a replacement if I manage to get it off?

Good pair of mole grips is a last resort to get it undone. Have you tried a single-hexagon socket (6 sided like the bolt was), the 12 sided bi-hex ones are crap for chewing bolts.

New sump plug should be available from VW for not much I would think. Get one before you remove the knacked one.

yeah sump plugs are only a few quid what about weilding a nut on to it see if that will work should do

You dont say what engine--if its a petrol be prepared for stripped thread in the sump when you get it out --it can be helicoiled tho--you can buy sump plug from VW dealer parts dept--yool need a new copper washer as well--

Its a turbo diesel engine, and the sump bolt faces the rear of the vehicle located in a cut-out of the under engine steel shroud.

The bolt (I still haven't shifted it) is steel, and the sump is alloy.

I intend to spend tomorrow with a file trying to file flats to get a smaller spanner on it.

Failing this I may attempt drilling it out.

I am reluctant to hit it due to fear of damaging the alloy sump.

Thanks for your replies, fingers crossed tomorrow.

That's it alright, 'cept mine's not as hexagonal as that!

Please don't tell me it's a lefthander!

If you don't want to risk a bolt punch, then maybe try all your hex/impact style sockets one size down. Drive one that seems to fit quite firmly on with a hammer and then get someone to tap the end of the T-Bar/power bar as you apply progressively more undo torque.

..and can't you first remove all that garbage that seems to be in the way

Looks like that's half the problem

The JX engine has two sump plugs on it. The other one is at the front of the sump pointing towards gearbox. Try that one.

Mine hasn't... and others I've seen haven't. The front ones still a blank casting boss.

Don't Syncros have them just at the front and 2WD ones just at the back?

Some do, some don't.
As a general rule they have one.

If all fails i use these. I have a complete set now near enough, have never failed to remove anything ive put them on. And as a bonus they are pretty cheap too! Your local machine mart an halfords stock them usually as well.

They do normally mangle the hex head, but if its gotta come out its gotta come out

Try a suitable sized pair of stilsons with nice sharp teeth and stick a hollow bar on the handle for leverage,option 2 beat the s**t out of bolt head to spread head and free off, then beat on a good quality socket (this may sound a bit animal but is how most mechanics deal with this problem,hitting the bolt will loosen the threads.)Always use the correct sized omni directional multi velocity impact tool(hammer)Good luck :
