Product Overview
A whistling noise, lean code, rough idle, oil around the cover, or a vacuum that is difficult to release at the oil cap can point to the valve-cover PCV diaphragm. On the GM 1.4L, a failed intake-manifold check valve can damage a replacement cover again, so the complete PCV system must be inspected.
The aluminum construction replaces the molded cover body while retaining the required sealing and crankcase-vent functions. Compare breather ports, coil mounting, oil-cap position, bolt pattern, baffles, diaphragm, and gasket; some vehicle years use different engine revisions.

Frequently Asked Questions
Q: Why can a new cover fail again quickly? A: A missing intake-manifold PCV check valve can apply incorrect vacuum or pressure and damage the cover diaphragm.
Q: Will the aluminum cover stop every oil leak? A: No. Turbo lines, oil cooler housing, front cover, vacuum pump, and crank seals should also be inspected.
Q: How do I confirm this is the correct part? A: Match VIN and engine RPO, valve-cover shape, bolt count, PCV ports and diaphragm, coil rail mounting, oil-cap position, gasket, and package contents.
Q: Is this supplied by the original equipment manufacturer? A: No. This is a new aftermarket item. Brand, model, and part numbers are used only to identify compatible applications.
