Ok then it probably isn't seised, its been in side an the plugs are still in. Whats TDC?
Ok so got to sort the timing out then. Got ya
Timing will be fine unless the belt has perished and snapped - VERY unlikely and easy to check.
If you want to do the cambelt and pulley before you fit the new engine (and it will be easier that way) you need to get the engine rotated until the timing is right. This is Top Dead Centre on both the crank and the cam.
That is what I meant by 'set the timing' - set the cam to TDC where all the valves are closed - only needed if you are doing the belt.
There will be a guide on here for doing the cambelt and it should be fairly straight forward since there is only one cam and a pulley.
Shout up if the belt is snapped and we can help line up the engine to TDC.
Good luck with the transplant. When are you aiming to get started?
