Craig impressive exit but ithink you dumped some oil on your way out , hope the Monza is still in one piece and did not fall apart on your way to brummy land .

Yeah the rocker cover gasket leaks a bit, common problem i think - well all of my 12v's have leaked in the same place!. I did fit a new one on Saturday but it was a bit twisted from being stored badly, i was in a hurry so it probably isnt fitted correctly!!
Diff is quite tight in this car, lots lof severe clutch action & it will merrily powerslide from a standing start! Being very wet helped a lot though!!
