How bad did I eff up?

I may have had a water leak somewhere and did my due diligence to determine including a pressure test.
But since I was unsure and didn't want to wait till I had damaged the bottom end I bit the bullet.
Thanks for making me admit that and kicking me when I'm down.

I did not mean to "kick you while you were down" I thought it was "odd" that you were changing head gaskets as a "precaution only" when you did not state any reason to change them; now you state that you "may" have had a leak, yet a pressure test did not confirm a leak, at that point I would have taken a pass on changing the gaskets.

I would have reused the factory head bolts if I had done the gaskets, they are a good fastener.

Make no mistake, I sometimes "do preemptive repairs" myself.

I'm old too, yet I consider it a win when I can still haul my sorry a$$ up off the floor after crawling around under the car.
