No exhaust temp or turbo boost gauges
Yes, 12.7 L with an EGR. Had the truck since 2005
Mine has the variable vanes setup. Maybe more exhaust is not required
It does it when engine is cold and hot.
2003 Detroit 60, 12.7 L, DDEC 4, EGR. While idling, turbo will cut in and out, spooling up and down. Sometimes it happens while climbing a...
Quick update. After about 500 miles, the problem returned. Made it to local Freightliner stealership and bought a THIRD purge valve kit in...
Quick update. After since the incident, I wiggled all the hoses and connections. Found no leaks. Tightened just a bit the connectors I could...
When the truck is running, absolutely ZERO problems and filter fuel stays level, no bubbles that I see. Also, no bubbles that I see in the fuel...
When the intake hose was pulled off, I kept the Devco check valve in. Nothing was backflowing out of it. I purchased a new one anyway. Going...
So pulled off the intake hose to the filter today. Immediately saw big air bubbles come up in filter housing and in about 30 mins, the Devco was...
That's what I thought. The check valve on the Devco is the lowest point before the tanks. It should prevent ANY backflow on the fuel intake side...
Yes, the Devco check valve is horizontal also. Plastic ball with a very weak spring (probably should be weak). I guess I'm just confused how...
Thanks for quick reply. The filter housing is vertical. That's a good idea to block off the inlet of the Devco housing. I'll try it. So even...
This problem is getting worse. Let the truck sit overnight and the Davco filter is empty of fuel. Draining all to tank I took out the check...
Took out the unloader valve and the housing it sits in. Applied some white lithium grease to all the o-rings as well as the little plunger and...

This has drove me insane for the last 2 weeks. After reaching 130 psi, purge valve purges and everythingis okay until the compressor kicks in...
Replaced air purge valve, problem solved. The old one had lots of crud and oil on it. Must have been stuck in the closed position, building...
Governor, filter cartridge, purge valve all replaced about 1.5 years ago. By the way, it's a Bendix AD-IS dryer. Seems like I'm having 2...
Air pressure seems to be okay. Compressor kicks into compression mode around 105 psi and kicks off at around 130 psi. One thing I did forget...
