Under the valve cover, of an overhead valve engine. They push the rockers on the opposite side of the valve stems. Overhead Cam engines do not have push rods.
The first overhead valve (OHV) engine was invented by the American engineer and inventor, Charles Kettering, in the early 1900s. Kettering's design was utilized in the 1914 Cadillac, which featured a V8 engine with overhead valves, marking a significant advancement in automotive engineering. This design improved engine efficiency and performance, leading to its widespread adoption in later vehicles.

No it does not. The only engine in the 1988 Cadillac De Ville was the 4.5 Digital fuel injected engine. The 4.5 engine is a 2 valve per cylinder overhead valve (not overhead cam) engine. It was a good engine but not in the power category as the Northstar.
