knocking after oil change again

I have asked this question here before. Each time I change my oil I get a violent engine knocking sound for about 2 or 3 seconds after start up. It goes away immediately but this cannot be normal. It seems to only occur after an oil change. I have tried adding oil to the new filter before installation and that does nothing. Could I be doing something else wrong?

I usually hold the gas peddle down (engine will not start) on the 1st start after I change the oil. You do this until the oil pressure starts to read. Never any knocking on my truck.

Knocking and engines that won't start on first crank after an oil change?

These are issues with both trucks IMO. After I do a change I just poke my head in the cab as I'm standing outside beside the truck and simply turn the key once to fire it up. Starts right up and no knocks or funny sounds at all.

Do you still have warranty?

I only turn the key once, and continue letting the engine turn over until the oil gauge starts to read. Turn key off...then start normal with your foot off gas.

i would think that with all the oil changes i've done and never had a problem that my new truck wouldn't be any different...i've never bumped the key to prim the system with oil to start and i've never had any knocks....

i'd be curious to see what other members do ...

I should probably read your signature more closely. Sorry 'bout that. So when did that extra quart pop up then, anyway?
