yeah i dont what worse hot or the 8 second dry starts ,any one else thoughts .

 

Mine takes maybe 2 seconds for the gauge to move, something sounds a little off with 8 seconds. How big are the lines and where is the cooler? Did you recheck the oil level? Keep in mind you now need more oil since the cooler is there.

 

6 1/2 quarts number 8 lines cooler mounted under rack and pinion.it use to move time engigin turn over good

 

What you hopefully did right after the cooler install is disconnect the coil packs and turn the motor over for a good 10 seconds to circulate oil through the cooler then recheck the dipstick to make sure the pan is still full before you start the motor...

My pressure builds immediately. I can't say I notice a difference between stock. 60psi cold and 45 psi hot with a Melling 12095

 

How do you have the lines routed. Wondering if the oil lines are draining down and having to be filled back up.

 

you have a cooler also ?i pulled fuel pump relay out ,spin engine over til built pressure .i am running same pump since rebuild melling 12095 . 10,000 miles on engine with foot in it .oil pressure 40 cold 28-30 hot since build .

 

they are running down from block on side of pan to cooler .i would say cooler at 8 oclock block at 2 oclock

 

I think number 8 lines are just to big for my oil pump so I took it off,made it 10000 miles with changing oil every 800 (knock on wood) going back to change oil every 800. might try it again my 408 /88mm set up in july

 

I have -8an lines are mine and no issues, although my oil cooler is the highest point in the oil system, so I guess it drains down when its off.

 

Changing oil often is smart
