OK:
I've replaced all of the pushrod valve tubes and seals, replaced the oil cooler seal, replaced the oil temp sensor, re-sealed the taco plate, replaced the transmission mounts and re-assembled the engine to the car.
Everything works perfectly, running at idle no leaks! Great!!! But when I re-attach the throttle cable, it is so stiff the throttle does not return to idle. No throttle cable problems for the previous 12 monthhs, and all of a sudden - BAM! I have re-routed the cable now so it is a straight shot out of the firewall and no difference - still very stiff .
#1 What have I done???
#2 How do I fix it?
My thanks to all...
