hi all

was in the throes of an oil change today and the sump plug refused to come out properly. its stuck half way in and half way out just spinning. needless to say oil is spitting out of the plug hole.

i was told that the sump plug screws into a retaining nut thats fitted to the inside of the sump pan and that the likelyhood is that the nut has come free, maybe due to previous overtightening of the sump plug on the last oil change, and that i now need to take the whole sump off and get the nut spot welded back into place.

can anyone confirm this or let me know what the problem is cos ive got a poorly car piddling oil and no way of getting the sump plug in or out!

thanks in advance as always!

Sounds like its been done up to tight and has stripped the thread in the sump

[TheBoy]

more likely stripped

[markey mark]

can you get a screwdriver behind it ? if so use it as a lever and undo it at same time might come out !

Wow you dont have much luck with your car do you?! Sounds like easiest option is remove sump and get a replacement?? I dont suppose a second hand one would cost a great deal from someone on here??

no need to remove sump. just remove plug, get it's size, drill the hole and fit a heli-coil.

[humbucker]

do you mean its stripped the thread on the sump plug or on the sump itself? and is it true to say that there is a nut on the inside that the plug screws into and it could be that?

used screwdriver on it to try prizing it with that but no joy, stuck half way out spinning. doesnt even tighten half way or anything, loose as anything it is.

[dieseldean]

sounds like its already been heli-coiled and heli-coil has lost its bite. try putting a prize bar between plug and sump and see if it will bite whist unscrewing.

Stripped thread in the sump im afraid

Quite common when people tighten the sump plug up too much

bugger. new sump and gasket i guess.

would it have been likely to have knackered the thread on the plug too?

[Dazzler]

By the time you get it out it may well have.

Only a couple of quid to buy a new one

[humbucker]

will call vx tomorrow and price up a sump pan, gasket and plug. doesnt sound like the kind of thing they'll have in stock though. anyone know what i can expect to be hit in the wallet?

grrr etc. i was ripping a v6 apart yesterday as well, if only i'd know then what i know now!!

[dieseldean]

cheaper option is to heli-coil it but it really does sound like it has already been heli-coiled

Same happened to me back in February, first off wrap string or cloth around the gap between sump and sump plug neck to stop oil leak. I then changed the sump (thanks to ISSUNAZ) thinking the thread in the sump was stripped, but it was the 'sump plug' thread that was worn, ie a new sump plug would of fixed the problem.  
P.s. Helicoil can be a problem if it is the sump pan thread due to it being very thin material.

Get a 2nd hand sump if you can, i should imagine a new one is rather pricey

JamesV6CDX has done this job on one of his, so he should know how much and whats involved etc.....
