Default S1 Timing Question/Cos Management
Hi Everybody,

I am just about to fit a new cambelt to my S1 which I have just fitted Cosworth Management. I have a few questions about timing the engine………
  • I have put the crank to TDC and my pick up wheel has the notch directly under the crank sensor, happy days.
  • I am beginning to position the camshaft. I spoken to Karl at NMS and he said that I need to fit the Cam to TDC with No.1 compressed. Last night I removed the rocker cover and spun the Cam and I was struggling to understand how I make sure that get this right. Do both the exhaust and inlet valves have to be seated?
  • Also, my pick up ring on the Cam Pulley has 2 notches on it which are to be positioned at 30 degrees and a further 90 degrees before TDC. But I have noticed in the Ford Manual that I should turn the cam 12 degrees BTDC when timing the car up to get the advance. So do I have to set the 2 notch markings from TDC or the 12 degrees BTDC?

Sorry for the slightly confusing questions?

Cheers

Darren
