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, as illustrated in the pictures on the right. Our aluminum billet 993 valve covers permanently cure the oil leakage problem. Their aluminum composition and finned surfaces also help dissipate engine heat more effectively.
