leaking sump ?
Discussion
My TVR is not fitted with a sump gasket, so I tried fitting one to cure the usual leaks. The gasket was sourced from a proper trade outlet. The gasket collapsed under the normal high temperatures of TVR engines and bits of the gasket found their way into the oil pickup.
Luckily I spotted the problem within a couple of days and stripped the gasket out again. If this had been left, the oil pickup would eventually have blocked and then the engine would have gone BANG! My advice would be not to fit a gasket, but to persevere with silican sealant.
Advice received from a mechancic on using silicon sealant on the sump was to first clean and degrease the mating surface of the sump. Squeeze out a continuous bead of sealant around the seal face (like toothpaste) then let the sealant stand for several hours even overnight. You end up with a rubberised sealant bead that is less likely to be squeezed out when the sump is bolted into place. It is also worth re-tightening the sump bolts again a few days after fitting.
Lastly, I was told that these sumps always leak, so if the oil drips are small, then leave it well alone.

dont know if tvr do one.i ordered mine from local motorfactors-4.0l rangerover.just make sure its a good quality(thick)one,some are like paper!mine were all payen brand,very good quality imho.
Got fed up with my '93 leaving its calling card via the sump.
Gotta agree with Mongoose, I got a "Landrover" (pre serp, I think 16 hole cork gasket), and got the local friendly garage to change it. The "Landrover" advise was from them as they said "Motor Factor" gaskets are rubbish/inferior to anything like a Cork "Landrover" sump gasket.
No more leaks either.
