Look on the gears, block and heads. You should see some small marks that all have to line up for it to be in time. I would sugesst you leave out the plugs so the engine turns easier. Turn everything slowly with a box end wrench untill you have all marks alighned. Turn slowly because in some engines the pistons will contact a valve and cause damage if things aren't correct. Hope this helps.
