Sump

[sherwin1983]

Hi all went to do the most basic of tasks a oil change and the sump plug nut wont undo it just spins any idears....

Sounds like it's either a knackered thread or the weldnut has detached on the inside of the sump. Either way you're probably best off dropping the sump to get a proper look at it and sort it out. It's going to be a messy job if it's still full of oil though!

Cleanest option may be to obtain a replacement sump, drill a hole in this one to let it drain then swap them over.

Seconded - you can't drill the sump plug as it's loose and spinning, and dropping the whole sump while still full will most likely end up with you spilling loads of oil everywhere which will be a 'mare to clean-up...I really think the spare sump is going to be the best way to go. If you do go this way though then be careful when drilling a new drain in your current sump - keep the drill speed low/medium so it doesn't get too hot and try to use a nice sharp/new bit designed to drill metal. The last thing you need is a hot drill bit potentially starting a fire on top of your bonce! Damn unlucky with your current drain plug - hope mine is ok...haven't gotten round to checking it yet!

Just a thought... surely if the bolt is spinning freely then it must be leaking oil out?

If so you could just let it drip out of time, Saying that if it is leaking you might find there isn't a lot left in there.. what does the dip stick say?

Drain the oil using an oil extractor siphon out the dipstick tube, Google it Pella is a good make. Drop the now empty sump and repair the plug.

If you do go down the replacement sump route a few things to consider.

1. They are not cheap and could be difficult to source a replacement.
2. The bolts that fix the sump to the block can shear off during removal/replacement, be careful and don't over tighten them.
3. The sump is sealed with RTV sealant not a gasket.

Some good options here - had completely forgotten about the siphon option. Just proves what a great resource the forums are Hope you manage to get it sorted one way or another - plenty of workable solutions to choose from now at least
