Afternoon all, I have been asked by a friend to have a look at his timing on his 2.2 omega the problem I have he decided to have a look today at it but got out of depth instead of timing the belt up first he just took it off as it was and now lost the timing.
  How can i know whether the timing is right when i turn the the crank and the cam  to see there marks.I did tell him to wait for me but 
 you know some people just don't listen.

Any advice would be great as going to try and sort it in morning .

Mark on each cam sprocket to line up @ 12 o/clock, and notch in crank pulley to line up with oil pump "spike" on r/h side as you look down. When all three are lined up need to lock the cam sprockets, re-fit belt and go through the timing procedure

Thats what i thought about doing ,but how would i know its on the right  stroke as dont the cam have to be on the combustion stroke ??
Ill turn it by hand first anyway make sure it goes round ok and lines back up

Easiest way for TDC on #1. Plug out and drop a screwdriver in the cylinder then turn the crank.
Did your mate remove the crank pulley

You can bend the valves even by turning the crank by hand.

My suggestion would be to get the crank to the nearest position where all cylinders are 90 degrees before TDC. This gets the pistons out of the way of the valves so you can get the cams in the right position.

You can use a couple of extension bars through the plug holes of cylinders 1 and 2 to keep an eye on the positions of each piston. (No. 3 follows no. 2  and No. 4 follows no. 1)

Once the cams are in the correct position, bring number 1 back to TDC and time up as usual.  You must not bring cylinder 2 through TDC, so choose the direction of rotation that will avoid this. You might need to rotate the crank backwards.

Another approach is to remove the cams completely, so all valves are safe, rotate the crank to the TDC marking, then refit the cams in the correct positions and time them up.

Timing mark on crank pulley will need to be at 6 o/clock then when cam sprockets are aligned

 Thanks look like ill be having a look after work ,
  so in other words if i put a screwdriver down the no 1 plug the piston will come up like it should and that the crank should be at 6 o-clock?
  its so easier to get it marked up first before taking belt off . not to worry im sure ill sort it for him .
 Thanks
