I believe there is an oil temp regulator that tells the turbo to let heat into the cab quicker during cold weather, thus holding down the blow-off valve...is this true?

my issue is when i start my rig in the morning, the blow-off valve is stuck down (ive seen and heard other rigs my same year do the same) causing excess air to blow out the exhaust...fairly common from what ive seen. the issue is that once the rig heats up, the sensor doesnt tell the blow off valve to open so everywhere i drive it blows excess air out the tailpipe and decreasing my engine performance. i say its the equivalant to driving with an engine brake engaged at all times. once in a while after i drive it initially i can stop at a light, turn the truck off and restart it and it will right itself but most of the time it will stay shut for very long periods of time.

anybody had this problem and how do i fix it.
am i right or way off on any of this

 

Sounds like the Exhaust Back Pressure Valve is staying closed. Its simply a butteryfly valve in your exhaust..no blow-off. Closes to warm the engine faster. You can simply unplug it. The connector is located at the front of the turbo just below the compressor housing. Its a 2 wire connector.

 

ok well is there a way to fix it or do i just have to unplug it.


any pics of this connector so i know exactly what im looking for?

 

You can fix it, Can be a couple things... Most of the time its the EBP sensor. Located on the front of the motor basically on the HPOP resivor. Pull the engine cover and you'll see two connectors in front, one is the oil pressure and the other is the ebp sensor. It has a long thin tube that runs down to the exhaust manifold on the passanger side and usually this gets plugged with soot. Ya can try to clean it out. It won't hurt a thing leaving it unplugged. Your truck may just take a bit more to warm up.

 

youll have to excuse me but in not down with the lingo like most of you. what is EBP and HPOP?

 

EBP= Exhaust back pressure

HPOP= High pressure oil pump
