dirty dages bottle
I have a black line around the top of my degas bottle,what could this be from.

Does it have a oily look to the top of your coolant or smell like fuel a bit

Coolant looks clean no oil or smell, truck is a 2000 with 118,000 miles on it.

I had the same thing on my truck.
First I had my oil tested at Blackstone - thankfully with negative results. Potassium or sodium levels in the oil would indicate coolant in the oil. Second, since I am new to the truck, I didn't know if the "soot" was residual from a prior event or symptoms of a new problem. I drained enough coolant (into a clean bucket to put back in) and removed the coolant bottle which I cleaned with soapy water. I could only get a rag into the first chamber so the other three chambers had soot which I couldn't remove. My goal in doing this is to see if the soot returns (which thankfully it has not). Third, I put on a Dieselsite coolant filter. Finally, I checked the oil dipstick for irregularities (which I did not see). I'll try to post pictures later on. As an aside, my oil cooler orings were recently replaced. I'm sure others will chime in and suggest that oil - coolant crossover often occurs as a result of deteriorated orings in the oil cooler. Good luck. |

Yes it looks just like that Tugly.

Pictures of my degas bottle before cleaning:
Attachment 100134 Attachment 100135 Attachment 100136 Attachment 100137 Except for clear condensation, my degas bottle is clean at this time. Although I forgot to mention it above, I did pressurize my coolant system to 15psi and I didn't see a pressure drop over the 15 +/- minutes that I kept the pressure on. In case it helps, A/Ox4 puts out a YouTube video on how to pressure test the cooling system. Unless the soot returns, I'm going to assume the soot was from a residual problem. If I were you, I would do the same. I think the other thing I read about when researching the issue was the potential for cracked injector cups. I believe you can test that by removing the injectors and pressurizing the coolant system. Unless the soot returns, I don't think it's necessary to go there. |
Well.... If it's that... the problem is not easy, or it's really terrible:
In my case, it took two problems in conjunction to get soot into the degas bottle. 1. Leaking copper washer on the injector nozzle or a loose injector. 2. Cracked cup below the injector fuel O-ring. The "epic" saga is in the injector cup link in my signature. The really-terrible: It could be a blown head gasket, but these are extremely rare. Are you getting loud injector knock, bucking and jerking at just the right throttle, and really smoky startup? |
No smoke on start up no knock truck runs good,I think I'll clean the ring off the degas bottle and put a new coolant filter on an see what happens.
