Question about 1994 Chevrolet S-10
This is a very common problem with the 2.2 Liter engine. The Cylinder Head Gasket has most likely failed due to expansion and contraction of dissimilar metals. The Cylinder head is Aluminum and the Cylinder Block is Cast Iron. The Cylinder Head expands at a greater rate than the Cylinder Block creating a Scrubbing Action on the Head Gasket. Another problem on this engine is the passenger side rearmost Cylinder Head Bolt is typically overtightened at the factory distorting the Cylinder Head and causing Gasket Failure directly around that bolt. I have had to resurface cylinder heads and replaced gaskets on many of these engines where these symptoms were described.
