the engine oil temps... not coolant. eot is part of the factor for the ebpv to actuate. here is a couple pics... NO high idle, NO ebpv acuation just sitting there idling. eot climbed a ton and the air out of the defrost vents where hot as ***... as in i opened the door, took my jacket off and turned the fan to low and turned down the temp control to the heat..
so in 21 minutes my eot climbed 111° with a normal idle with no valve actuation or high idle, and the heat from the defroster was HOT within 8-10 min... and thats just the oil temp which is WARM not hot! the air comming out the vent is HOT...
just because you have issues with your heater being ***ked up, and yes i have read your thread about it, doesnt mean it will be the same for everyone else. YOUR truck is ***ed up, try changing the thermostat, it could be that its stuck wide ***ing open and thats why your not getting any heat... or maybe your blower fan is week, or how bout a bad heater core, or how bout a simple ***ing coolant flush/change.... oh wait, this all has been suggested to you all ready and you obviously havnt done it.. so stop telling people the wrong ***ing info!
