Rubber sump gasket - to use sealant or not?
I have shortened my sump, ready to fit, as it is an XE engine I am using the rubber sump gasket as opposed to the two cork ones fitted as standard -
(this is taking some sound advice from one of the guys on here (thanks, Gary).
Photos of sump mods in my archive - comments are welcome.....
The rubber sump gasket has what can be best described as a slot in it all the way round to accommodate the windage tray.
I am just about to fit the sump and I was wondering whether to use any sealant as well?
I did a quick google and the info on there suggests silicone will lubricate the rubber and make it slip out causing a leak. Another site mentioned
using Hylomar sealant, but only on the gasket which has a cork part, and then only on the cork.
I suppose the same question goes for the rocker cover gasket.
What do you guys think - what have you done?
Thanks in advance for your replies.....JPG)

If the surfaces are good I would just use a very light smear of grease don't bother with silicone tho' its expensive too.
Phoned the local ramblers club today, but the bloke who answered just
went on and on.

My first couple of attemps on my 4AGE both leaked a little. I changed my method slightly and haven't suffered a leak since. All I do is seal the
windage plate only to the engine block and leave it overnight. Then next day I seal the tin sump to the windage plate and engine as usual.
The only other thing I did was to make studs from shortened bolts to make the whole bolting up process a lot easier. Especially when I was using a
wide winged sump. There aren't any gaskets for the 20V 4AGE I'm using.

I'm a fan of Hylomar blue sealant for these kinds of jobs. Might be okay without but it's not that expensive... If you're using a
setting sealant make sure you don't accidentally get bits of it falling off inside the engine...

I just used rtv silicone sealant as well. following advice from Ns Dev IIRC I used a cordless drill and zipped up the bolts to one of the higher
preset torque setting on it.
If it looks wrong it probably is wrong.

Thanks for replies and info, have now fitted it - rubber gasket IS easier to install - followed Dingz advice, (fittted it before the other info!) used
a trace of grease, bolted up but not convinced I've got a decent seal as the rubber has squeezed outwards a tad.
The Manual gives 11 lb/ft as the correct sump bolt torque, but I think the rubber gasket makes that hard to achieve (the book is assuming I'm
using twin cork gaskets).
I don't think they are even as tight as they would be with the torque setting on the cordless as Omega mentioned - do we continue to tighten? -
because the gasket is sliding out as I increase the pressure!
