Technical mk1 elx 90 timing
never done a 90 but same engine family as a GT engine which i have done....
timing a GT is done as follows, should be the same procedure.
Set the bottom end to TDC:
ON the engine block is a casting mark in the shape of a point, it is at 12o'clock as you look at the end of the crank. Line up the keyway nodge on the end of the crank to this cast mark as shown in this pic
wider view
When the bottom end is set to TDC, rotate the camshaft until it reaches this point below.
There is a small notch in the camshaft pulley, it is on the outside (visible side) and on the inside (against the plastic cowling). Line this notch up with the nodge on the timing belt cover when the viewing window is fully open. You can see the nodge directly above the belt on the photo above, also shown below
Now carefully apply the belt around the camshaft pulley, then the oil pump drive pulley, the crankshaft pulley and then the belt tensioner. Try to leave as little slack between the camshaft pulley and oil pump pulley because when you take the slack of the belt up with the tensioner you dont want this to pull the belt and turn either of the two main pulleys out of time.
Not sure if the 90 has a phase sensor like a GT but if it does remove the phase sensor, line up the small notch in the wheel inside the phase sensor by rotating the shaft until it lines up with the larger line in the view glass. Now place the phase sensor carefully back, being careful not to rotate the phase sensor, best to take your time and keep trying until you get it spot on, tighten the securing bolt and voila.
