Bmw M2 Engine Valve Cover Bolts

Bmw M2 Engine valve cover bolts

Engine valve cover bolts for your Bmw M2 start at $27.95, with 3 options from URO. These fasteners clamp the valve cover to the cylinder head, sealing in oil and keeping the valvetrain protected. When they strip, loosen, or break, oil leaks develop, gaskets fail prematurely, and you risk engine contamination or a fire hazard near hot exhaust components.

Signs your Bmw M2 needs new engine valve cover bolts

  • Visible oil seeping or pooling around the top edge of the valve cover, especially near bolt locations
  • Burning oil smell from the engine bay caused by oil dripping onto hot exhaust manifolds or pipes
  • Oil residue or dark crusty buildup around individual bolt holes on the valve cover surface
  • A loose or rattling valve cover that shifts slightly when pressed by hand, indicating a bolt that has stripped or backed out
  • Repeated valve cover gasket failures even after replacement, pointing to bolts that can no longer hold proper clamping torque
  • Visible corrosion, rust, or a bolt head that rounds off during removal, signaling the fastener has weakened and needs replacement

Which engine valve cover bolts should you buy for your Bmw M2?

Valve cover bolts are not universal — thread pitch, shank length, and sealing method vary by engine design. Some bolts use an integrated rubber grommet or washer to seal around the bolt hole itself, making it critical to match the OE specification. Your main choices come down to material grade and whether the replacement includes the sealing washer or grommet.

OEM-equivalent steel bolt with rubber grommet
Best for
Exact fit replacement matching factory specs
What you get
Correct thread pitch, shank length, and pre-installed sealing washer to prevent oil weeping around the bolt hole
OEM-equivalent steel bolt without grommet (bare)
Best for
Engines where grommets are replaced separately or are reusable
What you get
Lower per-bolt cost; you reuse or separately source the grommet — works only if existing grommets are in good condition
Grade 8 / high-strength aftermarket steel bolt
Best for
High-performance or modified engines with elevated heat cycles
What you get
Higher tensile strength reduces risk of stretching or breaking under repeated retorquing; may require sourcing grommets separately
Full valve cover bolt kit (bolts + gasket + grommets)
Best for
Complete valve cover reseal jobs or high-mileage engines
What you get
Everything needed in one purchase — eliminates guesswork, ensures all sealing surfaces are renewed at the same time

Remove any ignition coils, hoses, or covers blocking access to the valve cover, then loosen the bolts in a reverse cross pattern to release clamping pressure evenly before lifting the cover. Clean the mating surfaces thoroughly and inspect the threaded holes in the head for damage before installing new bolts. Thread new bolts in by hand first, then tighten in a cross pattern to the manufacturer's specified torque — never rely on feel alone, as both under- and over-tightening cause leaks or damage.

Frequently asked questions

How much does it cost to replace engine valve cover bolts on a Bmw M2?
Parts start at $27.95 for individual bolts on a Bmw M2, with full kits running higher depending on how many bolts your engine requires and whether grommets are included. DIY labor is minimal. Shop labor is typically billed as part of a larger valve cover reseal job, so bundling the bolt replacement with a gasket service saves money.
Can I reuse valve cover bolts on a Bmw M2?
Reusing bolts is acceptable if they show no corrosion, the threads are clean and undamaged, and the sealing grommets are still pliable and intact. Bolts that were overtightened, show stretch marks, or have rounded heads should always be replaced. On high-mileage engines, replacing all bolts during a valve cover reseal is low-cost insurance.
What happens if a valve cover bolt is stripped or broken on a Bmw M2?
A stripped or broken bolt allows the valve cover to sit unevenly, preventing the gasket from sealing correctly. This causes persistent oil leaks that worsen over time. A broken bolt still in the head requires extraction before a new bolt can be installed — ignoring it risks oil loss, gasket damage, and potential engine contamination.
Do valve cover bolts need to be torqued to a specific value on a Bmw M2?
Yes. Valve cover bolts require careful torquing — too loose and the gasket leaks; too tight and you crack the cover or strip threads in the head. Always follow the service specification for your specific engine. Most valve covers use a low torque value and a cross-pattern sequence to ensure even clamping pressure across the gasket.
How do I know if my Bmw M2 uses bolts with integrated grommets or separate ones?
Check your existing bolts before ordering. If each bolt has a rubber collar or washer permanently bonded around its shank, your engine uses integrated grommet bolts. If the bolt is bare and the rubber seal sits in a recessed hole on the cover itself, the grommets are separate. Matching this detail is essential to prevent oil weeping around bolt holes.
Should I replace valve cover bolts at the same time as the valve cover gasket on a Bmw M2?
Yes, and it is strongly recommended. Since the valve cover must be removed to replace the gasket, the additional cost of new bolts is minor compared to the labor already being performed. New bolts with fresh grommets ensure the entire sealing system is renewed together, reducing the chance of a repeat leak shortly after the repair.
