Pass side block threaded boss
Maybe a very dumb question, but I’m putting a totally stock 93 motor back together. On the pass side lower front of the block there is a threaded boss. Here is a pic.

Re: Pass side block threaded boss
Todd,
Here is a photo of a later block. IMG_0094.JPG And the block side of the EGR mounting bracket. IMG_0096.JPG The center threaded boss is not used for attaching anything. Perhaps a left over fixture mounting point from when the block was first machined at the factory. Sent from my iPhone using ZR-1 Net Registry
