EBPV question
When should the valve be coming on? Idle right? well mine always comes on when i'm crusin' at 55 mph. I know it comes on when cold but this is ridiculous. anyway the question is, do i have to just unplug the connector or do i have to wire the valve open with the valve unplugged?

I'd rather have it working than not working. Diesels do not like running cold. I have had to overhaul way too many diesel cylinders due to scoring up in the North Atlantic and Pacific. Boy was that cold!!! Even down here they need to run at least at your thermostats temperature. I have a brand new thermostat and blocked the front of my radiator a week ago. Today I took the fan off. It wasn't making enough heat to keep my wifes feet warm. That's too cold.

I was going to start another thread on this subject but don't have enough data yet.

Been married since dirt was invented. I won't let her drive it by herself so many times we just take her rig .. 98 Blazer, good grief that thing has heat up in a few miles. But it is a 4.0L and I get better millage that it does.

I THINK THE REASON SOME ARE HAVING PROBLEMS WITH THE EBPV IS THE TUBE FROM THE END OF EXHAUST TO THE BPV SENSOR IS PLUGED AND NOT SENDING DITTA TO THE COMPUTER.

That's possible. I've been doing a lot of research on this and if the BPV sensor does not see the initial closing (back pressure) of the EBPV on start up then it should disable the operation. Also I did not realize until recently the PCM pulse modulates (20 HZ 12 volts) the EBPV from 0 - 99 percent depending on IAT, EOT and BPV sensors feedback. I was quite surprised after 2 years my EBPV does still cycled on initial start up.

I drive my wife everywhere. Her employees and coworkers think I'm really special or something. In reality I just don't want her wrecking another truck and her parking spot is way too small too so I drive her.
My ebpv was on all the way to work this morning. I didn't get above 60 because the engine never got warm really. It was 15 degrees out.
I'm pretty ticked off now because when I got home I checked my tstat temp and it was only about 165 and the rad cap was only holding 8 pounds I think. Those parts are less than 4 months old!!! That's mostly why my engine never warms up. I'm running with no fan and the radiator covered too.
