2005 Trailblazer, hole in crankcase?
I recently had my 2005 Trailblazer 250 engine rebuilt. (top end, crank bearings, seals, rod bearing etc.). When I got it back yesterday I noticed their is a hole in the crankcase near a bolthead and cylinder head stud. In the picture the engine is sideways and if you zoom in to where the cylinder head stud ends is it looks like someone rounded/grinded that spot to get a socket on the crank bolt. The grinding/rounding looks like it went too far and is now a hole at the bottom of the cylinder head stud....
This looks like it was there long before I had my motor rebuilt and my guy didn't do it.... But my question is, Does anyone know if this will affect anything like compression, oil leaks or is this stud cavity blocked out from the internal parts of the motor?
Thanks for any help.
