Took care of the valve knock, turns out it was only oil and since I was flushing the engine, it fixed itself.
I took it for a drive and it does drive
But it looks liike it has a bad O2 or a dead CAT, or both, lots of exhust smoke coming out of the tail pipe, not like any of my other cars, I'm hoping it's just the O2 which should be dead from the burnt coolant.
The investigation continues.
As for ABS, unfortunately I don't know a thing about it, none of my cars have ABS in them. But I would start with electronics, the sensors, and then the computer, might be a lose solder joint.
