A search told me it is on the passenger side of the block, I have looked and see none. Maybe the motor I picked up had it removed. Where on the block should I look? Near starter? on front near smog pump?
Thanks

It's located on the passenger side of the block above the oil pan and in front of the starter.

 

I'm at home now, here's a picture:

 

So I looked all over near the starter, nothing at all. There is a single bolt, metric I think but it has no markings on it at all. None of those lines for grade and no 9.8 or somthing. I was gonna take the bolt off to see if knock would thread into it, but is is rusted on. I was afraid of breaking off the head so its soaking in liquid wrench right now. It right near the starter about solonoid level. Thanks for the pic GKK.

So I pulled the bolt out. Part of the treads broke off in the block . I drillied it and got that out with an easy out. After that I was cleaning the threads with a tap when coolant started pouring out of the hole. Did I drill to far getting the old thead out? Or did I find some kind of drain plug rather than the knock ensor location? The treads match the knock sensor perfect. Please help?
