Read some of the screwed up UOA reports and see for yourself. Pressure testing is fool proof, and if the lab is wrong it will save a ton of $$$$$$$$$$$. That TBN is high too for the amount of time the oil was in use. Could be a mistake too, lots of reasons why it might be high, no real facts though.
No argument here, just calling it like I see it. If I had to guess its a bad head gasket, but I'd be dammmmmmm sure before I started ripping into an engine.
Upon rereading your post, I read it wrong. I thought you were trying to "detect" a coolant leak, like MAYBE that was the problem. But you were trying to "confirm" a coolant leak before ripping the engine apart.
We in agreement on that!
Something else to consider is that if this is a warranty situation the dealer isn't likely to repair a head gasket based solely on a UOA. A UOA plus failure of the pressure test would be much more convincing.
Which lab did this analysis? Did the lab include any comments?
Thanks,
