Excellent. Glad you got it fixed!
My son wanted a car and the one he wanted was derelict with significant engine troubles. I told him I would help him buy it and fix it, but he was going to do most of the work himself. I wasn't going to fix it for him, but I would help him with it. Of course, there were bumps along the way and things he realistically just did not have the experience to do himself, but in the end it worked out great.
He's got a lot of sweat equity in that car and a healthy understanding of the work that he did. He doesn't baby it, but he knows that if he breaks it, he'll be the one turning the wrenches to fix it.
