Lifter noise on start up

[EMCD]

When i start my new 408 I get lifter clatter for about 2 seconds before the oil pressure shoots up. Is that normal?

[Chryco Psycho]

usually , the valves that are open when shut off will bleed down so it takes a few seconds for the oil pressure to reach them & pump them back up with hyd cams

[EMCD]

Great. So no worries if it clicks for a second of two?

[Chryco Psycho]

Nope 

[EMCD]

Great. After my dyno tune, it runs like a champ. My temp problem is now gone. Except for the vapor lock. any suggestions on a vented gas cap?

[Chryco Psycho]

Nope , drill a small hole in it LOL

my new 408 does the same thing, i thought maybe it was my oil filter was bad letting the oil drain out of it.

My engine builder said it was nothing to worry about. However, I'm a trust and verify kind of guy.

I hear the same thing if I don't drive my 2009 Challenger for a couple of days.

Man, I dig those cars. I hear they may come out with a cuda version in 2014.

[dodge freak 2]

I run racing 20w-50 oil in the 340 and hear no ticking at all

[EMCD]

how big of a hole? where should i drill it on the gas cap?

[Chryco Psycho]

Chall or Cuda ?
