RTV is a silicon sealant that is designed to be oil and fuel proof. You can get it from any car accessory store. If you have a Partco nearby get it from there. It comes in various sizes but the one from partco is a 330ml tube that fits in a mastic gun and costs about £3
Originally posted by fearless A common mod to cure oil leaks from sump gaskets on 20xe is to use sump gaskets off X17DTL engines - these gaskets r made from rubber and don't tend to 'seep' oil like the cork ones fitted as standard
The new gaskets for the 20XE are rubber impregnated cork and are very good, better than just rubber as the don't go hard like rubber does.
