Powerhaus did more tests on our car. 2nd TK test, mechanic said our car did not even change the color, better than most cars he tested that didn’t even needed head gasket replaced. Overnight pressure test, no leaks. Test drive, etc. I told them not bother with a compression test, too impractical. My amateur fix has been inspected by the pros, we are clear to drive it 😅
I remember talking to Pete during the day while he gave me a ride home. I hope this is just a great story we can tell folks and our grandkids, it’s well worth the cost an expansion tank and some coolant. It seems to be a great story for a movie: me, Pete and Andrew didn’t script this… its a true story.
So far it seems to be our car lives on, maybe the next custodian of the car can still bring it on the 100th BMW M anniversary day. Hope they read this story and remember to make the car happy or else it might try to kill itself again.
