Cat has really pulled off the biggest turd of all time with the C15/C16. Thankfully they'll be out of the truck engine market in 2010 and begin selling International trucks under their name.
All of our problems started with a blown head gasket and then a few weeks later a complete inframe. We've talked about it and have come to a possible cause sitting around the break table......it's the Ultra Low Sulfur fuel is all we can come up with why the rash of Cat rebuilds. No problems til the fuel changed.
The ULS fuel burns hotter and with the lack of lubricating sulfur, the big yeller motor can't take it.
To give you an idea of the problem, everybody knows how much Paccar loved putting Cats in their trucks.......for the 09's they're pushing the ISX since Cat has so many problems. Seems one Pete dealer has 6 or 7 trucks they can't even get to run and the engineers from Cat say they don't know if they can make 'em run or not. Seems they took the 07 engine and added 23 more sensors as an emission fix and they puked.....
Sure would be nice to buy a new truck with with an ol four and a quarter in it
; ) try and sell that "break table" scientific study to a room full of mechanical engineers ; )
Dry fuel (like the LSD fuel of 1994) causes injector plunger seizures, which causes the engine to run rough and stall ...I'm pretty sure that fuel lubricity is not making late model cat engines blow up ?
I do, however, know that "PACCAR INSTALLED" CGI pipes are frequently cracking/breaking, and then dusting CAT engines.
I'm feeling pretty skeptical about the "CAT adding 23 Sensors" story... never heard of that.
ALL truck engine manufacturers are having issues with regeneration control strategy in post-07 engines... especially with any application that is not long-haul. And, most of those manufacturers are having additional NEW problems with 07+ engines... not just cat.
