I assume your bottom end looked perfect when you tore into it? That’s what I usually hear.IF you are still on your original Head Gasket....I would consider that a legitimate concern.
Mine went 316K miles before giving up....and even then happened during an engine flush which suggests the material had degraded over time. I am at 330K miles now with a new HG and all else is running fine. I think nothing of taking it on trips since I know the general health/condition of the vehicle.
Im a little hesitant to do a PM HG job at my apartment complex parking lot: I’d have to be pretty desperate to do that.
