Engine valve cover mounts start at $22.95 at AutoBuffy, where you'll find 1 options from brands including URO. These rubber-isolated fasteners and grommets seal and cushion the valve cover against the cylinder head, dampening vibration and preventing oil leaks. When they deteriorate, you get oil seeping onto hot exhaust components, rough idle, and potential engine damage.
The main decision is whether you need individual bolt grommets, a complete mount kit with hardware, or an OEM-equivalent assembly. Material quality matters most here — cheap mounts harden and crack quickly from heat cycling, so matching or exceeding the original rubber compound is worth the small price difference.
| Option | Best for | What you get |
|---|---|---|
| OEM-spec rubber grommets (individual) | Direct replacement of worn grommets only, keeping original bolts | Single or sets of rubber isolator grommets matched to original dimensions and durometer rating |
| Complete mount kit with bolts and grommets | Full refresh when bolts are stripped or corroded alongside failed grommets | All fasteners and grommets needed in one box; simplifies the job and ensures matched components |
| Silicone-compound grommets | High-heat applications or engines with histories of premature grommet failure | Superior heat and oil resistance compared to standard rubber; longer service life in demanding conditions |
| OEM dealer part | Exact factory fit with no guesswork on material or geometry | Part engineered to the manufacturer's original specification; higher cost but guaranteed compatibility |
Remove any covers or components blocking access to the valve cover, then loosen and remove all valve cover bolts and lift the cover clear. Press the old grommets out with a pick or screwdriver, clean all mating surfaces thoroughly, and seat the new grommets before reinstalling the cover with a new gasket. Snug the bolts gradually in a cross-pattern and tighten to the manufacturer's specified range — overtightening is a common mistake that immediately damages the new grommets.
