check the timing marks on the crank pulley. TDC reference only to cylinder number one [meaning is measured off of cylinder one] and not the positions of the other cylinders, although they do have their own specific locations at TDC.

Simply put, find the timing marks, dont go off of the position of the other cylinders, and yes.. they will appear to be at the bottom of their stroke.

Yes. at cylinder 1TDC 2. and 3. are at BDC the 4. is also on TDC.

This goes basicly to every 4 cyl inline.
