Oil pressure start up
 

Hey guys,
I was wondering if this is normal. I have removed the stock oem oil cooler and installed the Z1 25 row Mocal thermostatic sandwich plate as per instruction. I am monitering the Aem oil pressure gauge And Upon cold start up it takes 15 s to build up pressure. 0psi 3psi, 5,6,8 12 to 30psi idle using 5w-30 full synthetic.
When I had Mocal thermostatic installed with the OEM oil cooler it would give me pressure right away

Where do you have the pressure sensor located?

I followed the DIY aem oil pressure gauge install. I used a T-piece fitting with the OEM oil pressure switch location infornt of the lower timing case. I would assume the OEM oil pressure switch would of picked up low oil pressure at that given time frame.
