[7 Seat Sports Car]

I replaced all my exhaust valves nearly 2 years ago now and had no idea how to set up the camshaft timing.

I don't remember trying to turn the camshafts by themselves without the timing belt fitted. I set the crank mark to line up with the oil pump housing mark, installed the head cover and camshafts as they should be and after gradually tightening the 40 ish head cover bolts (1 turn at a time on each bolt to avoid distorting the cover), fitted the timing belt and turned the engine over BY HAND with a spanner on the crank pulley. It wasn't easy and took a bit of effort to turn everything but it proves that valves don't touch pistons. Spark plugs should be removed so you don't fight against pressure build up when manually cranking.

Do you have a VVT pulley?
