Oil Cooler thoughts
So as some of you read from an earlier post, I took my truck in to have the oil cooler replaced. I got a phone call from the dealership saying that during all the tests performed, they could only get a 3-4 degree difference between coolant and oil(So no issues and no oil cooler change and wasted time putting it back to stock).
Whats funny is when I was tuned on HD300 my temp differences would be 10-13 degrees difference.
I then put my truck back to stock with no programming and stock exhaust. I did my testing with the blackmaxx just being used as gauges. The temp difference was between 6-8 degrees.
Then the dealership get 3-4 degrees.
What the heck is going on with all the inconsistencies? Should I pull the temp sensors and clean them? Would that even matter?
All tests I did were performed with engine up to temp on the highway doing 75mph(just under 2000 rpms)
On a side note, when i went back to stock everything. The weird rough idle and shake disappeared when in park and idle drive. Right before i took the Blackmaxx off my truck(so still tuned) I let the truck warm up, white grey smoke was coming from the exhaust and it was idling VERY rough, the worst I have seen it. I turned the truck off then back on and it went to a normal smooth idle with no white smoke. Any thoughts on this?
