Product Description
CUMMINS 4936172 OEM VALVE COVER BOLT WITH GROMMET (SHOULDER ISOLATOR CAP SCREW) – ISB 6.7L (2007.5–2024)
The genuine CUMMINS 4936172 OEM valve cover bolt with grommet is the correct shoulder isolator screw used on all 2007.5–2024 6.7L Cummins ISB engines. This bolt secures the valve cover while its integrated vibration-isolating grommet prevents leaks, cracking, and distortion of the composite valve cover. If your valve cover is seeping oil around the bolt grommets or any fasteners are missing, stretched, or brittle, replacing them with real Cummins hardware ensures long-term sealing and durability.
Each isolator bolt includes the molded grommet required to maintain proper clamping force without over-tightening. These bolts often deteriorate from heat cycles, causing oil seepage or rattling at idle. Installing genuine Cummins replacements restores proper tension and protects the valve cover and gasket on your 6.7L Cummins.

Frequently Asked Questions
HOW MANY OF THESE BOLTS DOES MY 6.7L CUMMINS USE?
The 6.7L Cummins valve cover uses multiple isolator bolts. Replace them all together for even pressure and best sealing.
MY VALVE COVER IS LEAKING — WILL NEW BOLTS FIX IT?
They help, but leaks typically require both new bolts and a fresh CUMMINS 4984750 gasket. If the cover is damaged, replace it as well.
CAN I REUSE OLD ISOLATOR BOLTS?
Reusing old bolts is not recommended. Heat cycles cause grommets to harden and lose clamping force, leading to leaks.
IS THIS A GENUINE CUMMINS COMPONENT?
Yes — CPP Diesel sells only authentic Cummins OEM hardware for proper fitment and longevity.
