I attached some photos I keep finding coolant leaking from my truck I’m afraid it might be bad head gaskets

It’s possible it would be the head gaskets but first i would check to make sure nothing is leaking coolant up top. Check the hoses going to the turbo. The EGR has numerous hoses. Might need to pressurize the system with a specialty tool to find it.

Its probably unlikely but when I bought my lb7 I had an identical coolant leak appear, the moron that had the truck before me messed with the transmission and cracked my rear engine cover and bell housing and it leaked coolant through cracks in the cover.

Did you ever find out where the leak is from?
