Since your doing a big job you don't want to do it again, replace the rear main seal with an O/E one

I've replaced mine in situ, I used plenty of Permatex Ultra Blue Multipurpose RTV Silicone Gasket Maker. The seal is still perfect 35000ks later.

Exactly my view as well.

So did you slice off the rubber locators on the sump gasket or work it over it thanks.

I think I did have to cut some rubber, and clean of the old silicon. It was hard to get the seal in because you can't skew the seal in as you have to slide along the crank. So it can done. But if you have the time just drop the sump, you may even be able to just undo the sump bolts a inch or so then you can just hang the sump down a bit.

Triumph Rover Spares in SA claim they don't fail, only a handful in all the years they've been out was what they told me.
They were doing a tranny replacement on mine and I asked if they'd do the seal if there was any sign of leakage and was told she'll be right they don't leak.

Well after ordering a genuine L/R rear main seal there is no difference between the Bearmach UK and the genuine L/R seal its made in India except the price ones $40 the others $65 they are identical and both look crappy compared to the one i removed from my engine i have attached some pics of them side by side the LH is original (note the locating dowels look better casting) the RH is genuine L/R
looking at the flutes the rear is original 280000ks the front genuine L/R new
