Possible headbolt failure early signs?
I have been experiencing "check coolant level" i topped off on some coolant light went away. next day boom light is back check my reservoir its low again. no visible leaks under car the oil for some reason will not get up to temp sometimes was thinking because it was cold but after some spirited driving it will but eventually cool down again below normal temps this has me thinking i have coolant in my oil can anyone provide any input please. engine does have the updated headbolts.

I mean you could just drive around and hope someone on the internet can tell if there’s coolant in your oil… or you could pull the dipstick and see if it’s in your oil?

That is the early warning sign. But if you already have new head bolts, unlikely. Probably just weather/temp change.

This was from my '09. Literally just got back from getting new head bolts installed. Anyway, this was the telltale sign
As BLKROKT said, since you have new bolts, highly unlikely
