Ben, I've found if you use Permetex No. 3 (its a non-hardning, non-silicone sealent that you brush on) you shouldn't get any leaks - as long as you dont bash the seal in with a hammer. Use a peice of pipe the same Dia. to use as a drift to knock it in place.
With the Head Gasket, I use VHT copper coat (spray can) or Hylomar (spray can) - works really well.
With the other gaskets I use Permetex 'Ultra Blue' for things like sump/timing cover, & Permetex No.3 for the rocker cover.
As for the Manifold, dont use anything. Just put it on dry.

Hey all,

I'm putting my A14 back together at the moment and thought I'd benefit from all of your experience.

I've heard that unless you use a lot of slicon sealant on the rear main seal...it is likely to leak.

I was thinking of laying down a little oil on the head gasket, sump and rocker cover gaskets...is this a good idea?

Anything special I should worry about for the manifold gasket.

Oh - and anyone interested (in Oz) I got the gasket set from Bursons for $108 - it is a AA Gasket GC277 containing:
