Engine failure after oil change

An oil filter and/or oil changed didn't do all that.

It was on the very edge of going. If you would have leaned on the fender too hard it could have made that blow.

Off topic rant...

I feel for repair shops that get cars in for oil changes that are ticking time bombs. Then they get blammed by some unsuspecting and unreasonable car owner that never maintained thier vehicle.
