Uh, not sure I totally agree with that. Failed oil cooler seems more likely. Usually when the EGR cooler fails you'll end up with white smoke out the exhaust and pushing coolant.

 

if the oil cooler is failing you would have oil in the water if the egr is failing you will can get additional pressure in the coolng system also white smoke if leaking into cylinders

 

I agree with that. That doesn't agree with what you said before though... You said if the degas is dirty black looking it's a failed egr cooler....

 

Depending on how the egr cooler fails you have exhaust gas which is full of black carbon, if coolant can get into the engine then carbon can get forced into the cooling system turning it dark or almost black. unless you are injecting propane then you have no carbon as the diesel is burned at a rate of 99%.

 

I was thinking the same thing

What are the numbers on this good price?

 

EGR cooler failure usually leads to coolant leaking into the exhaust system and being burned out. If it's a small leak and it's just being pressurized the otherway, usually it will just push coolant out. Never really seen black coolant in the bottle from an egr cooler, though I guess it's possible.

I'm not even going to get into the propane debate. I don't see how adding more fuel will make another fuel burn better. I think Nitrous would be more appropriate. Nevermind!

 

let me no how much and send me some pics, I have an 04 MACH 1 maybe we can do some trading

getting a little off track but I can tell you what i have experienced I have over a 1000 miles with propane injection and my oil looks like it came out of the bottle. I know of truck that has been on propane since it was new 189000 miles and no egr problems only one the dealer knows of. i have gotten up 25 mpg on the highway and 17 in town.

 

It's just an untimed fuel. Seems silly to go that way when technology has come so far to control the timed burn of diesel. That's just me. I know a little bit is ok for mileage, most of the issues seem to be with anyone trying to make any power with it. In which case, nitrous seems to be the cheaper/easier/safer route.
