Bad Timing. Need help.
i swapped my heads and changed my timing chains and such and now i have run into a problem upon reassembly. So i could use some helpful advice now guys. I put the valvecovers on and the timing cover back on and the harmonic pulley. So i started turning the crankshaft and i get almost halfway from TDC and it binds hard. I know my timing is off but I wonder how far off. A degree or 2?
If im halfway from TDC what piston do you think is hitting the valves? Do i need any special tools to set the timing? I have the crank position tool im about to order the cam lock tool. All the synchronizing tools I’ve seen her for the 2004 and up or for the three valve set up. Please help.
my engine is the 4.6L 2valve
If you need more info i have a pi swap thread that has pictures and my play by play as the days have gone on.

So im just trying to figure this out if the crankshaft turns 90degrees from TDC does that mean that now the number 3 piston is now ready to fire? Or is it 180 degrees and the number 3 piston is ready to fire?

Sounds like you got your valve timing wrong.

what do you mean? Like do you mean to take off the timing cover and valve cover and move the cam a degree over and try again? I was thinking maybe i would need some funky tool to degree the cams and that special cam locking tool.

So no luck. Its binding still I’ve watch 6 YouTube videos and i have the timing marks lined up the chains bright on both end to the timing marks on the sprockets. I dont get it.

When you time it is the crank keyway at the 12 0'clock position? Always only move the cams to line the marks not the crank, which i'm sure you already know.

I had this put up on another site many years ago.....it's gospel, no special tools required (specially a damn cam lock lol).
