EOT/ECT delta, ford service records, head gasket?
I just went on a 30 minute drive and on flat ground with an outside temp in the mid 30's I saw deltas of anywhere from 6-9 degrees with average of 7 or 8 degrees at steady speeds of 65-70 mph. However, coming down a couple mile steep downgrade my Deltas quickly went to about 14-16 degrees and seemed to stay there for most of the decline. My ECT dropped quickly while the EOT was a little slower to react. Once back on the flat ground my delta were again anywhere from 6-9 degrees.
What do all of you think about these numbers?
By the way I've been a longtime reader of the forum and usually don't as k questions since most of the answers are found by a little searching. I've owned an 2005 Powerstroke for a little over two years and so far I've got gauges for EOT, ECT, EGT, tranny temp, and whatever else I decide to use on my scangauge. Also, I've got a coolant bypass filter, high idle mod, running AR9100 w/good synthetic & AR6200 w/2-stroke mix, SCT x3 with tunes from Eric at IDP.
I'm going to do the complete flush of the cooling system with restore, restore+, and fill with good elc this spring. At that time I've got a complete egr delete kit to install and am trying to figure out how my oil cooler is since the previous owner had at least one head gasket repaired. What is an Oasis report and how do I find out what Ford has replaced on my vehicle while it was under warranty for previous owners?
My best choice is probably to replace the oil cooler as well when I have the manifold off and update everything from standpipes, dummy plugs, hpop stc fitting, turbo drain & feed lines. I have a long list written down so there might be more, but those are the ones that jump to my mind.
So basically my three questions are:
1. How are these deltas and should I check them during hotter weather for a better comparison?
2. How can I find out when and what ford has already replaced on my truck for previous owners?
3. What is the easiest way to tell if i need to do head gaskets and studs when I do my egr delete and other upgrades?
My coolant has puked before, but I've never really heard the tea kettle whistle and it might have been from me putting in too much coolant when i put the coolant filter on. I've read about the weak coolant caps and have the updated one ordered. Once I put the new coolant cap on should I top the coolant off to the new low line and clean everything up and see if it puts anymore white residue on the degas bottle?
I also want to thanks you guys in advance and for all the valuable info I've read on this forum.
Any thoughts you have on my quest for durability are appreciated as well!
