Yes,
It was probably connected. when you overheat you can cause several problems.
1. toast valve stem seal so that they dont work anymore.
2. Mess up cylinder seals by causing rapid wear, oil goes by the rings.
3. Wearing main and rod bearings, causing more oil to be put on the cylinder walls and creating more problems for oil rings to attempt to control.
4. Rings can become brittle from overheating. The only way they have to get rid of heat is thru the cylinder walls and thru the piston. Overheat both avenues of heat exchange and the rings can over heat.
could be any one of these or a combination of any or all.
