i dont think u can put the dizzy in 180deg out but i know that you can get the cap on 180deg out ive done it before not on my rs on another cvh

not sure about the test lamp easiest way is to is to do as bd says above lign up the bottom timing mark to the 0 on the cover check it on the top pulley against the head if im right in thinkin that should be no1 so take off the dizzy cap and start from there 1-3-4-2 round the cap if you are unsure which way to go turn the engine with a spanner on the bottom pulley think this is right then you know its all in the right order if you need any pics just ask
