PRIME (First Start) Your ECOBOOST!

I've never given this any thought, but I can see the logic. As a matter of practice, I've always killed the injectors and cranked new engines over a bit before the initial start to make sure everything was well lubricated before firing. Back when I first got into the trade, we used to pull the distributor and use a tool with a drill motor to spin the oil pump and prime things up. Northstar engines were notorious for engine clatter from bleed down if they sat for more than a few days and it's been well published that the majority of engine were happens on cold engine start up, so anything you do to mitigate that by getting everything that needs it lubricated before the rpm's come up would be a positive in my find.  It's a good, out of the box way of looking at things!

I am glad you brought up the Northstar motors.  They were terrible for that.

The very reason I traded in my 18 Jeep with the 3.6-liter Pentastar V6 engine. It would sometimes exhibit a brief cold start rattle even within a 24hr threshold period. The SHO has never produced any such rattle since purchasing it new with 2 miles on the OD.. I just hit 75K on the OD. Z

Mine too.  Just clicked off 75k as well and my have never produced any such rattle as well.

I haven't seen it in something as new as the "18" Chrysler 3.6l engines, but if you go back a few years we had quite a few that had the "bullet" style hydraulic valve lash adjusters that would bleed down and clatter. Some would pump back up, most required replacing them to get rid of the valve clatter. There was a procedure that involved reving the engine several times to get them to pump up that worked on occasion. There's so many systems on modern engine's that are oil dependent, even down to the exact weight, it's getting really critical. We're lucky with our 3.5l.
