water pump wobble?

[weider1717]

Sent my water pump off to Author Gould which is a highly recommended guy for restoration water pumps.

I put it back on ran the truck a couple hundred miles and it started hydrolocking (hard to start) pulled the rain plug and green antifreeze...

also, noticed the pump itself and pulley wobbled never noticed this before could any of this play hand and hand with what issues I have now if was it just pure luck my head gasket decided to go right after I put the rebuilt pump on.

I can't see how they could be tied together but just asking...
