Now a permanent solution to the leak-prone factory 993 plastic valve covers. Over time, the factory plastic valve covers separate around the metal mounting bolt sleeves and oil inevitably leaks (illustrated below). Eagle Day 993 billet aluminum valve covers permanently cure the oil leakage problem. Plus the air craft grade aluminum composition and finned-heat sink outer surface greatly dissipates engine heat vs the OEM beer cooler plastic. The 993 was the first and last Porsche to use plastic valve covers.
