Received my sump yesterday from andyc but there wasn't a gasket (only silicone) which I'm sure is correct but can someone confirm? andyc was not available today for comment 

The tube of silicone is half the size of your reglular bathroom sealant so wondering if I need to use it all? How long should I leave the silicone to cure before filling with oil? Will the excess silicone on the inside of the pan cause a problem when mixed with oil? How much should I torque the sump bolts?

Thanks

I worked for the V6 plant on warranty and durability for 13 years, yes later sump supports / pans didn't have a gasket we used silicone sealant - but you need to use the correct one inorder for it to seal correctly - we used loctite 5900 - this is expensive (£30 a tube) but is the dogs 'dangle berries' of sealers - it goes off in a few minutes so by the time you have got the sump back on you can fill it with oil no problem. the torque is 20 NM for the sump support and 8NM for the sump pan yes it does splay out but no problem - just dont forget to seal around the bolt holes.

That would be the proper stuff to seal it then if Andy supplied it and NO you don't use it all unless you want to bung all the oil ways up and starve the engine of oil all you need to do is run a small bead all round the sump, be carefull not to smear it all over the place when you offer the sump up.

they do sell in on the net you can get smaller tubes with a plunger like a large shringe - the same sealer was used on the cam covers after years of them trying various sealers, vauxhall (dealers) started using the grey GM sealer as used on the vent housing and heat ex changer cover - although this is cheaper it tends to go hard and not as elastic.

Thanks for the reply. Didn't think to seal around bolt holes  the silicone I have is the grey type, the one used for the oil cooler. How late is 'later'. My car is 2001

thats a later one as we started building them in 1993 and the plant closed in 2004 - the grey can be used but it goes too hard i would i always use the correct factory loctite 5900 as its not a job you want to do every year

[SMD]

Shall I put a bead of gunk on both surfaces or would that be excessive. Can you clarify sump supports, would that be the M6 bolts and the sump pan the drain bolt?

[kevinp58]

The later ones are the facelift ones the easiest way to tell is they have the front grill on the bonnet, and not separate.

[kevinp58]

No just the sump will be enough

[v6man54deg Geffd]

the support is the aluminium part - the pan is the sheet metal part with the drain plug  - pust seal on the part you are fitting but use a good cleaner / de greaser on both parts before applying any sealer

Thanks fellas, I think all my questions answered.   

FWIW, the new pan looks like its one piece of steel with no ally insert. So should avoid this happening again.

Alloy insert is attached to the engine.It sits between the bottom of the block and the top of the sump.

I'm confused now. I thought the reason for my sump bolt spinning was because the alloy insert (where the bolt goes in) that is spot welded to the sump pan has cracked, hence not coming out.

Is this what you're on about?

Different bits of ally 

The lower steel sump that you've got a stripped sump plug in is bolted to a large ally upper sump which in turns bolts to the main cast block. 

The lower steel sump can be changed inside an hour or so ......... you'll need to book a week off work for the other bit.

Sorry,I misunderstood.
