Good point! Just below the oil filter element sits a spring loaded "black" button. You can take your filter back off and press it a couple of times to make sure it is seated. I believe that is what you are talking about Mudstrokin.

 

^ correct sir. And if i'm not mistaken it will caus ethe truck not to start and build pressure correct?

 

It deals with pressure hence the spring load effect, and obviously it works in metering the oil input/output through weight or pressure applied to the button. As weight/pressure of the oil compresses the spring down is where the actual metering takes affect. If the button or valve (whatever it is called) is stuck down would block oil input. That would send a signal for a "no start" condition to the PCM. I'm probably way off base with my logic, but it sure seems that is the reason for that "spring loaded button/valve", or it's only there to **** me off.

 

Thats probably it, just like everything else not needed on these engines

 

Thanks everybody for your inputs it is a stock truck and one more thing to add is after i would get done cranking i would go to the exhaust pipe and it would be seaping out black smoke like it is getting to much fuel could that be one of the same symptomes the the oil filter check valve?

 

My car acted similarly a couple of months ago.. My fuel line was just clogged. I had to blow the line out with an air compressor..

 

Well so far from some research I did I found that on the 05 models it is common for the fuel stand pipes to go bad along with a quick connector on the hoop. Apparently now there is updated stand pipes with check valves in them and a newly revised kit for the quick connect fittings. After I get those parts installed I will reply back with news if I get the truck running.

 

....FICM all the way.

 

Got truck running it wasn't the ficm. But now it is running rough with white smoke and it still takes awhile cranking to get it started. Any more ideas

 

Do you have AutoEnginuity? Running rough could be injectors not receiving prime yet. If you have something to monitor the engine while it is running will pretty much tell you where to look. Can you be a little more descriptive as to running rough? If you give it a little throttle what does it do? Are you certain all your pushrods and rocker arms were properly seated on installation? Kinda of chasing a ghost here right now...
