Question can't find any answers on this on any of the sites but usually 1 out of 5 cold starts my oil pressure is slow to come up about 4 to 5 seconds before it builds pressure what could this be? Its almost like when you change ur oil and theres that delay when you first fire it back up. The truck is a 2011 LML

I've noticed this a few times on mine, but never found a fix.

I've had the same concern after my two engine builds. Sometimes it's fast, other times it's super delayed, and sometimes it doesn't move and sets an oil pressure circuit code.
