They said it wouldn't work, you did it anyway. How did that work out for you?

At the time I was fixing many cracked aluminum heads in Ford Escorts by having them welded. A shop next to me had a Chevy Luv which is really an Isuzu. The shop insisted that it couldn’t be fixed because the crack was through an oil passage and the clearances would be too tight after milling the head flat. I took the head to my head guy to be welded and he drilled out the oil passage and pressed in a steel tube to take care of the crack in the oil passage. I gave the head back to the shop to install. A couple of days later to tell me that they were right about milling the head because the trucks compression was all over the place wouldn’t run. I had them move the truck to my part of the shop where I checked the compression and again it was all over the place. The motor had a double overhead cams so I checked the cam timing. They had just thrown the motor together and must have never lined up the marks. I reset the cam timing and did a compression test and all was good. I then had the other shop finish it up and the truck ran like new. The one thing I left out is because it was 4-wheel drive you had to pull the motor out in order to get the timing chain removed. This because you have to remove the oil pan and the 4-wheel drive components won’t allow you to drop the oil pan.

Bottom line is I did want the other professional shop said couldn’t be done and I only do this as a hobbyist.
