We're cracking on with it now, intake gasket had failed in exhaust crossover area and was blowing oil up the intake manifold studs !
Just waiting on gaskets and new rocker nuts so can put back together
But before stripping it we checked and found a few leaks that have been sorted, and I've ordered a proper flywheel cover for it, but hot start on the ramp it was kicking back hard on cranking !
So thought I'd better strip distributor and see what's going on in there as must be to much advance at cranking.
So strip dizzy and found one of the weight arms for mech advance the bushings had failed and it's worn half way through the shaft, all looks to have been caused by the retaining e clip had come off !
Can't buy the parts for them anymore so have had to do a workaround but seems to work ok now on the bench
