Headgasket on a diesel

Hey all,

I'm driving an E300 (1996 with 155K miles on the odo) and the mechanic took a look while it was up on the lift and noticed a coolant leak and then said it was the head gasket but I haven't noticed any considerable amount of coolant loss (several months ago I did need to top off my coolant but that was several months ago and I only added ~300 ml - 3/4 a can of beverage for those non-metrics).

So how common is this as an issue? Anyone else ever have theirs done?

Seems to be a leak outwards and not a mixing of coolant and oil (yet).

Car is running fine, not overheating not blowing smoke - not more than a diesel should when gunned!

thanks

Being that it's an external coolant leak it doesnt pose as much danger as an internal leak. As long as it's a minor leak keep monitoring it, but the inevitable is waiting for you. Good luck!

-Keep an eye on the leak.

-Check out Black Stone Laboratories. They will analyze your used engine oil. An engine oil analysis will tell you many things about the wear in your engine... including if they find coolant. You know your headgasket is on the "outs" if they find coolant.

Ditto. Head gasket repairs on the OM606 aren't common unless they are over-heated. Just about like any other engine....
