Well I doubt he blows it this month since I doubt it leaves the garage this month
As for the stocker I had engine with 130k on it and I overheated at least twice a week sometimes daily due to a not stop coolant leak id fix one it come back or another happen but it held for 7 months doing this yes the leak was that serious (block was cracked didnt know until it came out the car)
I say this as I think i have early signs of bhg on my current engine lol But the stocker is strong the rod bearings I find are weaker
