[TRUBBS]

going to look at a truck tomorrow after work, its quite a distance a way so i cant just swing it by my buddy at the dealer and have him check it over like i hoped. anyways i got an edge insight cts, will that be able to tell me what i need to know as far as the oil cooler goes?

Between the oil and coolant temp, didnt see it mentioned

Yes.

Thanks! What's normal operating range on the 6.4? Anyone know if the edge can read oil temp?


Also, in the picture on the add, it looks like it has a grayish haze out the pipe. It's got an exhaust & chip (not sure if it's deleted or not tho but assuming it is)

Is a slight haze/ or a puff normal? Don't know if it was idling or just on start up.

Temps can vary. I've got 4.30 gears and I'm around 199ect 204-206eot. When I have my 350 with 3.73's it was 192ect 197eot. Then there's the ambient temps that have an effect.

Mine has a slight haze, it's deleted with h&s xrt pro. My ect and eot are within 5 of each other at all times when up to temp towing or not. Usually 194 in winter and 197 in summer. It'll creap slightly over 200 when towing heavy

I wouldn't be too concerned about the haze. Mine hazes at idle. Always had after time and delete.

I believe they all haze at idle. But check the blow by and see how bad it is

you must not tow very heavy

5* delta while towing is crazy low

 

[BKopp]

Up to 8 ton sometimes

I've never owned one that young LOL

140k on my reg cab. 7* delta at 85mph in the high plains yesterday.

my 1 ton will touch 12* in the summer pulling a grade in the mountains... and by pulling, I mean pulling it's own 10,000lb fat ass up the mountain! LOL

Could be I don't go over 75mph very often and try to stay at or below 70 while towing. Tennessee hills suck. Also I'm convinced that there's not a straight stretch of road anywhere near me
