Newbie Q's on: IPR; IPC; Blue spring mod.
Hi, another newbie on here looking for knowledge on getting an '05 6.0 to a very health status and keeping it there. While working on removing the FICM today, with help from this and some other good sites, I told my wife that when we bought this truck new in July of '05 I had no idea that the experience would be something akin to having another child. It reminds me of the book title from the late '60's or early '70's called "The Zen of Motorcycle Maintenance."
Last summer during vacation the truck odo went from about 73,500 to near 76,000, expiring the first ESP warranty we had purchased in '08. On one cool morning in the Great Smokies we noticed white smoke exhaust; back home one week later temp spiked, mech'l. fan stayed on. I had it towed to dealer who had done all maintenance since new. Paid for the usual repairs of EGR system, oil cooler, fan clutch; bought ARP studs and had the dealer (hopefully) install them. In the spring Ford had sent a flyer trying to sell me another ESP warranty. Since I had not used the first warranty I bought, have a kid in college and everything seemed to be fine (in hindsight I see the symptoms were there, I just didn't know what they meant), I declined to buy another.
After the repairs were done we bought the Extracare warranty for another 4yr/48K miles, and of course 4 months later I am having the FICM rebuilt, which is not covered on the warranty. Having done a fair amount of reading on these forums in the last 4 months, I am of course thinking about what else would be wise to do for prevention of more disaster.
I have done several searches to get a definition of "IPR" with no luck. I do see the location of the IPR valve in the 6.0 Bible illustration, and think I have a reasonable idea of what it does, but would like to know the meaning of the letters, as well as "ICP" (I get the idea it has to do with injection pressure?)
Two others I would appreciate just a brief explanation of are:
- Blue spring and Blue spring mod
- 6.4 banjo (bolt?) mod
Other pertinent info on my truck is: alternator seems to be putting out only 30-45 amps, according to a basic metering by the dealer and by O'Reilly's, but not sure until i can get it to the dealer for a tech to hook up the diagnostic computer, but will have it replaced on my warranty; just replaced both batteries yesterday, 11-17-12.
I have had a Bully Dog downloader/programs and Monitor installed since 12/07at about 26K miles. I rarely get the after-turbo pyrometer temp up to 800 degrees, usually not over 650-700 degrees. Havn't towed or been on any long trips since the engine repairs with exception of 500 mi. roundtrip last weekend. I didn't watch the ECT/EOT delta very closely on that trip, or I don't remember doing so, but I have occasionally noticed a delta of 12-14 degrees. Most of my driving is local small town and rural two-lane, and only about 3,500 miles since engine repairs. I live two miles from my office and many days don't drive more than 6-7 miles; make a 90 mi roundtrip to closest city, plus 20-30 miles of city driving, every 1-2 months.
Thanks for explanations of above items and any other comments/suggestions
