Ok here is the story...
Last summer I bought a 2004 f-250. Love it. First thing I did was bought the edge insight cts gauges to see what was going on. Worst day of my life. I watch those damn gauges waiting for something to happen. Ok the deltas were around 20-25degrees and that scared me. So I tore down the truck in my driveway and did what I was supposed to. Oil cooler, EGR delete and coolant filter.
Deltas were now at 8-12 and the truck was running great. I was upset that the deltas were still high and I thought that that I didn't flush the system enough. I did flush the hell out of it. I was still puking and everyone said that my coolant level was too high. I hooked up a gauge to check coolant pressure. 16-18psi all the time. Never returned to zero. Damn...
Ok so a couple of weeks ago I started collecting parts for head gaskets with arp bolts. I bought a 2005 engine and had the heads pressure tested, vacuum tested, and decked so I would have little down time. BTW I have 2004 heads for sale
so I did a cab off head gasket repair. Not too hard, just a long process for the first timer.
I had an exhaust leak and a slight fuel leak but over all it was a success. Ok now on to the gauges. The EOT and ECT deltas are now down to only 2 or 3 degrees. Awesome, Don't need a new oil cooler. Coolant pressure is up to 8 psi at operating temps and drops with the temp. Everytime I get into the truck in the morning the psi is at zero and rises to 8psi at operating temp. Before the gaskets it would go to 16-18 but never drop to zero.
Just some observations that I have before and after head gaskets.
