Not having a lot of buildup is a good sign, so is not having coolant visible in the intake.
Hey brother, I dont know what to call you but I just wanted to thank you for the information. I have learned more about my truck from you in a few days than I have in weeks worth of research, your knowledge is invaluable!!
So it sounds like I may be catching this early. I know it doesnt change the inevitable, but at least I feel more comfortable knowing that there probably isnt any permanent damage done. I think the issue is still there due to the fact I have coolant blowback through the degass cap and that the bottle itself is cracked.
I discovered something else this morning. A few months ago I noticed a strong diesel smell whenever the engine was running. I started investigating and found a drip coming from the diesel filter housing where that long "O" shaped o-ring is. I bought a new one and replaced it, really wasnt any big deal and that stopped the problem. That was about 3 to 4 months ago. This morning I noticed the same diesel smell and that was the first place I looked and sure enough, it was dripping again. Is that the normal life expectancy of this o-ring or is there another potential problem brewing.
One other thing, since all of these problems started, I have noticed that when I first start the truck in the morning, it runs really rough and seems to pulse for a couple of minutes until it warms up, after that, it runs fine. There is also a very strange and strong odor that comes from the exhaust as soon as it is started and that is the only time I notice it. Any guesses what could be causing this and that o-ring to fail so soon?
