BMW S85 Stainless Valve Cover Bolt Kit

Overview

This FCP Euro stainless steel valve cover bolt kit is a stylish and functional upgrade for the BMW S85 V10 engine. Made from 316 stainless steel, these 34 replacement bolts offer high corrosion resistance, improving upon the original plated steel fasteners. The kit includes upgraded NRW silicone grommets for a superior seal and can also be used on the ionic knock module covers. Install by hand-torquing to 6Nm, avoiding impact guns to maintain the finish.

Installation summary

This valve cover bolt kit installation requires medium skill and can be successfully tackled by experienced DIY mechanics comfortable with precise engine bay work. You will need basic hand tools including a calibrated torque wrench and a clean workspace to replace the fasteners one by one along with the new silicone grommets. The most important thing to watch out for is strictly hand-torquing the stainless bolts to six Newton-meters while completely avoiding impact guns to prevent stripping and to maintain the finish of the hardware. Professional installation is not strictly required for this job, but extreme care must be taken with the fragile S85 cylinder head threads.
