Sealant for rocker cover gasket and sunp gasket

Guys, I've got the LR gaskets and wanted to make sure I won't use the wrong sealant. Would Loctite 510 be suitable? http://www.loctite.co.uk/loctite-4087.htm?nodeid=8802626535425 Or what should I go for? Thanks!!

If you are using gaskets, do you really need sealant too?

The rocker cover is a rubber gasket/seal shouldn't really need a sealant too, and the 3 bolts only want nipping up and not too tight.

The sump doesn't have a gasket if you go by the book, just has RTV sealant.

If you want the best there is,

This is the stuff vehicle manufacturers use, I know Merc use it, its not cheap but it is the best there is.

Thanks, nobber, I will check if there is any available here.. If I can't find it, would Loctite 510 be sufficient, do you know?

Mick, I think the manual says that some sealant is needed to hold the rocker cover gasket in place (marked with As):

I would assume some sealant would be needed to hold the gasket while positioning to the sump as well. Could it be you were talking about another engine? The TD5 should have a gasket. It's on the drawing below marked under 3:

Ok, guys, now I've researched the topic more and have found that Island4x4 and Britpart list Loctite 5900 and 5980 as an equivalent for STC50550, which is recommended in the TD5 manual. Will go with that..
