Hello,

I am in some dire need of help and guidance as this truck is my only source of transportation as a college student. I replaced the lower intake manifold gaskets in my 2003 3.0 and during that process I removed the push rods and rockers to get the intake out. I got everything assembled as it should be. Now onto startup…at first it was hesitant to start up and once it started up there was an inconsistent popping/knocking sound coming from the engine. ALSO, after the engine is off it has a small low popping noise. Now I’m not sure if this has something to do with the push rods or rockers that I removed and reinstalled (torqued to 24 ft lbs).

I think it is also worth noting that I replaced that driver side exhaust manifold gaskets aswell.

help please…

 

First check the firing order on the Coil Pack
Connector side
1 2 3
5 6 4
front

Seen here: https://static.cargurus.com/images/s...1600x1200.jpeg

The 5 6 4 side often gets mis-wired

But so can the 1 2 3 side

Follow EACH wire to its cylinder
Ford numbers V6 cylinders this way
3 6
2 5
1 4
front

Did you keep the push rods in order front to back in each side, and their up/down position the same?
You should when not using new pushrods

But shouldn't cause your current issue
Could be an exhaust valve rocker or push rod has slipped off, long shot
