This is a newb question. 1st post here.
Just bought an '05 Ex 6.0 with 93k miles and was wanting to do a few things to increase the odds of it going the distance. Will probably dump it when the clock ticks 200-220k. I paid $17,800 for it and it seems to be in great shape.
I was told by a seller that at 150k the head gaskets will need replaced and it's a $3-5k job. This got me to searching various forums. I have completely read thru many multiple threads and have gained a good understanding. But I don't particularly want to spend the money or time necessary to do a full bulletproofing.
Here is what I am considering:
1) Do a good coolant flush with Cummins Restore, Restore Plus, distilled water. Fill with Rotella ELC coolant per instructions here and elsewhere.
2) Replace fuel filters, air filter, radiator cap. Can I put a pet**** on the drain plug on the lower pump housing?
3) Install an SCT-iTSX-4015 programmer "dongle" and monitor using Ipod. Monitor EGT, ECT & EOT for a length of time under various conditions to establish overall engine health.
4) If all is well, get a custom tune to limit the EGR action, improve economy and a little HP. Powerstrokehelp video on Youtube seemed to suggest that the EGR valve cycling could be reduced instead of a EGR-delete kit.
Engine oil cooler, EGR delete and 4" exhaust (dissing the converter) are not without question but I am mainly interested in extending the life of the engine with the best bang for the buck. Is the EGR delete a must, is it a disaster waiting to happen? What percentage of owners who do nothing but regular maintenance have to deal with this? Or can the 3" exhaust just have the cat removed?
ARP head studs, new head gaskets, remote oil cooler, etc. seem to be beyond the risk / reward scenario (spend 2k now, maybe save 3-4k later). Seems like keeping an eye on the vitals while driving can stave off $$$ in repairs.
My problem is, I can do the wrenching but I don't have time as I bought the Ex for the family (wife and 4 kids). Also, sold the wife on the Ex with the idea that it might take $1200 to "bulletproof" the engine based on some optimistic/cursory forum searching I did beforehand.
I know this is a question that's been answered a 1000 times, but I have read many posts and it's becoming overload.
