does it take oil to come up thru the pushrods?

I took my valve cover off today to check the rockers out...
i took it off when cold and after sitting for a couple weeks and after starting it took about 70 seconds before the oil started coming out of the pushrods...

is this normal because i also have extremely high oil pressure?

it's an LT1...

 

First, what is extremely high? Second 70 seconds is about on par for how long a cold started motor would take for the oil to reach the top end. You could always crank and hold rpms at 2,000 to ensure it gets there quicker.

 

70 PSI at idle... and the needle disappears when at WOT...

 

Holy Crap!

I think that's about par for the course seeing as it has sat for a while.

 

Now, thats some oil pressure! Our 92~ s10 with 60k miles on it has about 70lb of oil pressure on cold start, but the needle does not disapear when we WOT, of course im not sure if iv ever WOT when it was cold.

 

it disapeares when it's hot also... and the pump, spring etc... is all stock...

check out the oil guage in my clip... low left

 

damn, never seen mine do that, but have noticed the more miles i put on it the more pressure i have

 

I would bet that's a sending unit issue. I can't imagine your pump actually producing that pressure.

 

yea thats alot of pressure. crazy.
