Early BMW N52 engines use aluminium valve covers that are secured with one-time-use stretch bolts. These bolts are designed to elastically deform when torqued, applying an extremely precise and even clamping load across the valve cover and gasket.
Once stretched, they cannot return to their original length — which means re-using them risks uneven sealing, oil leaks, and in some cases cracked valve covers.
This complete bolt set from Febi Bilstein replaces every one of the factory stretch bolts required for an early N52 valve cover removal and refit, ensuring the gasket is clamped exactly as BMW intended.
Replacing the bolts at the same time as the gasket is the only way to ensure the repair actually lasts with proper OE-grade fasteners designed specifically for BMW’s N52 valve cover system.
