Valve Cover Hardware Set - E90 325i/330i, E60 525i/530i, E85 Z4 3.0i/3.0si

The valve cover on early N52 engines is held down with this set of lightweight aluminum bolts. They were aluminum as part of BMW's efforts to make the engine and car lighter. Unfortunately, the aluminum bolts are one-time use only as they stretch when torqued into place. In other words, you cannot re-use them. This makes them required any time the valve cover is removed such as for gasket repairs or sensor replacements. Other times people will see an oil leak and think the bolt is just loose - tightening the aluminum bolt then cause it to snap! It's little wonder that BMW replaced the aluminum fasteners with steel from 2007 onwards.
When doing any sort of repair or maintenance there is no replacement for genuine factory parts. Turner Motorsport carries the Genuine BMW brand with pride and has the parts you need to complete your next project with confidence.

This set of bolts has you covered for a valve cover job and are Genuine BMW parts with the correct spacers and washers. Sold as the complete set.
