I have a ej25 in the back yard, I'm going to go and look at it, OK, I'm back, I found the timing mark on the crank pulley pointing straight up at the little notch in the casting, and the number one piston at top dead. The heads are out on it so I can't tell you about that. Hope this helps. I know it is hard to get in there, even to do the spark plugs, let alone the belt and water pump.
Still confused by the markings. Arrows, I, and II
I remember reading something about the marks on the heads, If you can only find one mark, you are all set, but if there are 2 marks, one will be the diamond and the other a dot, What the difference was, was different engines took the same head. Or was it different heads went on the different block marks, now you got me confused. Anyway, depending on which head you have, 2 valve, 4 valve, will make a difference in which mark you choose. Your heads must have been off at one time, and ground, could have easily been put back on wrong. Don't know how, It should have busted the cam by now. I would clamp the cams on their dots, loosen up the belt, move the crank by hand to it's dot, and then tighten up the belt, It should not move very far, It can't spin around, pistons will hit the valves. When it is on it's mark, you can turn the engine over by hand to make sure it is free. If it doesn't spin free, somebody dropped a screwdriver in there. And as long as you are rebuilding, you need new wires, they will cause all kinds of trouble and you will never think about them.
