Thread: Rear main bearing install

I am considering using a good quality RTV sealant in the grooves on the side of the rear main bearing rather than the cork T seal. Has anyone ever done this and if so was it successful, the main bearing can be accessed from both sides after installation so any excess RTV sealant can be cleaned off so that the risk of plugging oil galleries would be eliminated. The cork gasket is a hangover from the old days when there were no other alternatives, just like the old asbestos rope rear seals in most older motors such as the old Perkins diesels. By using RTV I think you can fill the groove prior to installation then force the sealant into the grooves after the bearing is secured to ensure the grooves are full. Once the sealant has hardened it should be adhered to all surfaces and prevent leakage.
Am I right in thinking this is a better alternative or should I install the cork T seals.

There are a lot of series Land Rover engines getting around with cork "T" seals in them.
I have seen rubber or maybe neoprene T seals advertised too.
Make up a good tool to assist in installing the bearing block.
The main thing is apply a good sealant behind the half circle seal retainer etc, as they can leak from there.

This is a "blue bag" seal kit, but it offers the option of fitting either rubber or cork T seals.

Cheers, Mick.
