12 valve help!!
 

Got a 95 12 valve I recently completed a head gasket on. It'll spin over till you start adjusting valves then it won't budge. Anyone ever had this happen before?:argh:

Is it possible you've not got a push road seated correctly? If its not in the tappet it'll bend the push road and possibly damage the valve. Or you've got your lash way to tight. Forgot to ask, what was shaved off the head and what gasket was used?

I had everything set by finger and it ran its course perfectly. I don't get what happened. We started adjusting valves and tried to spin it over to finish it and it like "locked" up. Can't go forward or back. I had a couple mess ups along the way with push rods not being completely in but i addressed all those along the way. Like I said, it worked perfectly with the valves all lashed by feel and not tight

By feel? I think I would go back over the pushrods and valve lash with a fine tooth comb and a set of feeler gauges. If it turned fine at first and you changed your lash and it stops turning over seems like a logical places to start. If it was valve lash you would think it would go back? Maybe a timing pin left in? Or barring tool left in the bell housing? Didn't have cam out did you?

No, Cam wasn't out, been turning it over with the balancer, used a method I read about on here for setting TDC so I didn't use the timing pin. I set everything by feel so I could get everything together and make for sure it didn't bind or anything. And all was well until I started setting lash with the feelers gauge.

You might loosen them and make SURE you are at tdc but it really shouldn't matter as long as you're on the bottom of the cam.

Would that make them bind forward and back?

No. Lol
Hydrolocked by something but that would not just appear because of tightening the lash. Could you have accidentally adjusted one of the wrong valves at tdc? Heck who knows maybe the bad luck fairy stopped in and dropped the kdp.

Sounds like you adjusted the valves 180 out. Take and loosen every single rocker completely off. If it spins freely your good to go. Now to set the valves, find top dead cylinder by pushing the lock pin on the back of the timing cover between the vacuum pump and injection pump. When you first push it in it will move. But 99.9% chance you won't have it perfectly at TDC. Rotate motor till it pushes in. Set the correct valves. Now you will need to rotate the crank 360 degrees. Easiest way is to mark the balancer and rotate the engine clock wise till the mark is in the exact place and the adjust the rest of the valves.

That was my initial thought but even if he left the adjusters all the way loose it would open the valve enough to prevent adjustment I would think.
