ok, i rebuilt my hole front end. that turned out great.

I droped my oil pan to replace the gasket, and noticed my oil pick up tube was full, so i went ahead and replace the oil pump and pick up tube. and after i started my truck a loud banging was happening. im thinking that the pickup tube could be getting hit. it gets louder with the high rpms. has anyone ever had this problem. i dont think i it could be the oil pump.

 

did you remove the oil dipstick before you removed the pan?

 

yes and even so. there is a guide rail in the pan that shroud stop that from happening

 

did you prime the new pump?

 

ok have never done that. well how do you do that

 

procedure is towards the bottom of the page.....

would an unprimed pump make such a loud bagging

 

an unprimed pump can kiss your motor goodbye

 

Without being primed, pump may not start pumping oil. Did you notice if you had oil pressure?

 

Did you note the position of the tube on the old pump and install it the same way on the new pump?

Do you have pressure?

Also, I have replaced my pump once and main seal twice without priming... truck still runs like a champ although the main seal (or something else) still leaks... lol... So while it is a good idea to prime, if you forget it is not automatic death to your engine.
