On my recommended, thought you all might like this.


The 5.9 was sold in Dodge pickups starting in 1989, not the late 90's. The B Series engines were not developed with Intrashnational, and thank goodness for that! It was an industrial engine, and the marine versions were turned up some, but to say they were de-tuned is a bit much.

While I do believe the 6.7 is not overbuilt like the 5.9, there are plenty of 6.7s in commercial service with that kind of mileage. There is a hotshotter on TDR with a 2018 4500 approaching 200K miles, and his prior 6.7 was sold with almost 400K and is still going. The only 6.7s that were really troublesome were the pre-DEF, heavy EGR versions 2007-2012(?), when Cummins stepped on their **** trying to avoid DEF. There are plenty of guys with tuned Third Gens that have bought Fourth and 4.5 Gen trucks and say they outpull tuned 5.9s. My '05 was all stock, and I can honestly say my '19 pulls better than my '05, which was a great truck, would ever dream of.

The guy that installed my headers sent me this pic of a 2004 F150 he changed the spark plugs on. 7/8 broke and had to be extracted[emoji15]e8d4805fe5a5a3b95605ec4adb513210.jpg

Question, could it be that GtL base oils are so pure that it doesn't hold additives as well as other base stocks? I like Pennzoil, I am sold on it, but I don't know any other oil that has as much additive fall out. Why do you think this is?

Well

But,

We know that some base stocks just do like suspending additives as well as others. Some use a small amount of ester just because it is good at suspending additives.

An example of what im saying is PAO. It has trouble suspending additives. Wonder if GTL is not good at it either.

Yes, it was a ginormous POS. I had one in a '92 ********, and the rest of it was no gem. First and likely last Toyota.


I,m a Subaru guy, got two, 01 and an 05, Every headgasket between 2000 and 20009 i believe, WILL fail. Thing is it usually starts at about 120,000 miles, usually takes til about 180,000 to get so bad you need to fix. Gives you plenty of time. Already done this on the 01. The other, no signs yet. (105,000 now). Other than that great vehicles. Oh wait, they eat wheel bearings too. Ok other than that their great. :happy175:

Think they eat coil packs like rats eat cheese, and timing tensioners too. Big ford fail #2

Ecoboost #3

But nothing will top the # 1 spot the 6.0 Powerstoke


All this and Ford and i are really still friends. Acquaintances

Oh yes they eat coil packs. My previous work van was a 2005 E250 with a 5.4, that thing would burn out a coil pack almost yearly. And yeah the 3V 5.4s chewed up tensioners and timing componants almost like clockwork after 120k or so.

IMO the 6.4 Powerstroke is worse than the 6.0. The 6.0 can be made pretty decent but the 6.4 is basically a throwaway engine. Ford even kind of admitted it was a pile when they only used it for 3 model years...

Did not know that. I knew they sucked too but not the way you described.

Yeah I only know that because I follow Powerstrokehelp on youtube. The 6.4 has so many parts that are literally designed by international to fail. The one off the top of my head was the valve guides are steel. So instead of being brass like the 6.0s and 6.7s, they wear the valve stems out as well as the guides.

Other thing about them is they run too hot because they barely fit in the engine bay, they have DPFs that are fed by dumping fuel into the chamber on the exhaust stroke, oil dilution, on and on and on. Quite possibly the worst diesel in a truck in the last 25 years.

The 6.7 PS is a pretty good engine but its Ford designed, not International...
