Hi,

There are small cut-outs on the crown of the pistons to allow for the valves to open correctly, don't worry abot these. If the valves had touched the pistons before you wolud know about it!!!

Before starting the car on the starter, turn the crankshaft using the bolt used earlier. You will soon find if the timing is correct without doing any damage. Remember to do two complete revolutions of the crankshaft (thats one of the camshaft). The only way to set the injection timing is with a DTI gauge. Expensive and complicated. If the injection timing is slightly wrong, you will notice a lack of power. This happened to me on the first engine, and I was able to adjust in small increments by trial and error (only on pulley with three adjusting bolts and only slight movement - 1/4 of a degree region).

If it is badly out, there will be a lot of white smoke, or the car simply won't start. Don't confuse this with air in the fuel system though, if you had the filter off, the only way to get around this is to have some one crank the starter and opeb the lower banjo bolt (19mm I think) on the pump.

But if the injection timing is all that is out, there should be no problems.

Having said that, it is the worst feeling in th eworld when you are siiting there ready to turn the key!!!!

Good-luck

Kev.
