First, It has been a long time since I have torn into an engine. I had to have the head on my atv milled. I wasn't paying attention when I pulled out the push rods. I was putting the head back on and noticed the push rod difference. The top of the push rod looks machined into a half circle.

 

First question, is this normal? If so, which valve is it for? Second question, if it is not normal will the missing part fall directly into the oil pan? Before I tore it down the engine had no power, I could see puffs of smoke come out of the head and the block. Hence the milling.

 

Trying to figure out if I need to rebuild or put a new engine into the atv.

 

Thanks for the replies.

I would ASSUME they should both have the ball on the end. Does the engine have tappets (excuse my ignorance on the subject) If it does, the ball may be stuck in a tappet. 

Not sure either. Don't see anything on the rocker arm.

There should be a ball on both.  

 

I would assume it would be in the oil pan, but if you don't find it there it is teardown time.

That is what I was thinking! Just trying to cover all my bases. Thanks for the reply.

Also check your shop floor for this little ball to see if it rolled away somewhere if you dropped it by chance.
