I’m currently replacing my cylinder heads on my ford windstar 2003 3.8 v6 engine with re-manufactured heads. I’ve got the cylinder heads installed. Now I need to put the push rods and rocker arms back on. In my Haynes manual it says I have to set the rocker arms to TDC for each cylinder but my mechanic friend said that I don’t have to adjust anything on the valves, push rods, and rocker arms as its hydraulic and should adjust it self.
My question is after installing my cylinder heads do I need to do any adjustments to the push rods/rocker arms/valve settings on a windstar 2003 3.8 V6? I’ve heard valve lashing and other processes like the TDC for each cylinder/pushrod but i’m unsure. I don’t want to destroy my new heads and I can’t find concert information on Google about my specific car. If anyone has information or can even point me in the right direction I would be grateful. Thanks,
