Lesmyer When i first pulled the valve cover off everything looked to be okay. till i drove it for the 2 time and pulled the valve cover off again and that is when i noticed it. I am guessing after pulling the head that is why the push rod got bent. But it also could be from the collapsed lifter. But not sure. Just wanted to give you all a heads up. I pulled the head off and found a bent Valve on the exhaust side of Cylinder #4 No piston damage. (well from what i can see) The head looks to be okay. I haven't pulled the piston out to look at the rings. Not sure if i'm going too. what are your thoughts on this. Just worried about not having compression. (should i pull the piston or do you think it will be okay.

A valve getting bent by hitting a piston could have tweaked the connecting rod, also it may have cracked piston at the wrist pin. Even with no visible damage to the piston. Been there seen this.
Also IMO you have something else going on as I can't see how a collapsed lifted will hold a valve open to get bent - should be opposite not opening all the way.
What RPMS were you running when you was running down the road, High RPMS and floating the valves will let valves slam into a piston and very well deflate lifters at the same time.

my Rpm was at 2000 at 30 mph when it made a funny noise.(Like a card in a bicycle spoke.) That is when i Immediately took my foot off the gas Pedal and pulled over to the side of the road. Looks like there is no damage done to the piston. But like you said it could be internal. I am going to take the head down to a machine shop. and see if they can find anything

sounds to me like you may have a broken valve, piston or rod. Also a crack in the cylinder wall will cause a bad smell if coolant is leaking into the compression chamber. Is the compression problem only in #4? Also check timing.

Oil gally too #4 lifters may have plugged off deflating the lifters hence the card in spokes sound { rocker rattle }
With no oil flow thu the lifters too oil the rocker and valve guides the rocker may have dried out and seized or the valve guide with no oil to lubricate it may have over heated and caused the valve too drag holding it open and let the piston hit it bending the valve stem.
Valve bending may be the collateral damage in the end of events

I have good Compression in all the other cylinders. I think the best way is to rebuild the motor. by replacing everything but the heads and the block. My question do i have to remove the front axle to get to the oil pan off. Or can i just lift up the motor to get the pan off.
