Engine Bearings, Gaskets, Mounts & Block Service Components

Shop engine bearings, gaskets, engine mounts, sealing components and engine-bay accessories at Black Ops Auto Works. Compare ACL and Clevite bearing references with Cometic/MAHLE sealing parts, Innovative and other mount choices, and listed covers or service fittings. Choose the specific repair or build scope before completing a parts order.

Main and Rod Bearings: Measure the Assembly

Match the bearing to the engine family, journal position and exact size designation. ACL references distinguish standard, journal-undersize, extra-clearance and housing-oversize configurations. These descriptions address different dimensions; one is not a universal substitute for another.

Establish running clearance from the measured crankshaft and assembled housing/bearing with the correct tools and builder specifications. Load, oil viscosity, temperature, alignment and journal condition all matter. Neither a horsepower threshold nor a bearing brand establishes a universal tighter-clearance target.

Gaskets, Sets and Mating Surfaces

Compare single seals/gaskets with the actual contents of a top-end or service set. The selection includes Cometic Hellcat blower-snout/plenum gaskets, manifold gaskets and other engine-specific sealing references. They serve different joints and conditions.

A head gasket requires the supported bore, thickness, surface condition and fastening arrangement. Gasket thickness does not simply follow bore diameter. Use the exact gasket and fastener procedures; do not assume every boosted engine requires the same studs or that new hardware repairs unsuitable sealing surfaces.

Engine Mounts and Swap Interfaces

Innovative, Torque Solution, PERRIN, Whiteline and other listed references address particular chassis/engine mounting arrangements. Confirm bracket geometry, transmission pairing and retained parts on a swap before choosing a kit.

Compare the supported isolator material/durometer and the vehicle’s comfort or competition priorities. Full mounts, inserts and service components have different scopes. A stiffer mount can transmit more vibration; it does not establish a universal wheel-hop or launch improvement.

PCV, Plugs and Other Service Components

Radium PCV valve references distinguish their ORB/AN or barb interfaces. Wehrli crankcase-vent fittings and Billet Technology PCV covers have different jobs. A cosmetic cover is not a replacement regulating valve.

Block-off plates, fittings, seals and sleeves require their exact service location. The listed tube sleeves and adjuster sleeve should not be described as cylinder liners. Review each component’s actual function rather than assuming every item in this broad category is an internal engine-block part.

Covers and Engine-Bay Finish

Billet Technology caps/covers, carbon fiber engine/fuse-box/radiator covers, shrouds and badges supply separate appearance or service-access functions. Match the engine bay and retained component dimensions; a cap cover and a working pressure cap have different roles.

Check clearance to intakes, superchargers, hoses and other modifications and follow the stated attachment/finish-care instructions. For internal work, keep the machining and measured assembly plan separate from cosmetic accessories so the order supplies the parts needed for each job.

Choose Your Part

• Define bearing/internal service, sealing, mount/swap or engine-bay project.
• Identify exact engine, mating component and dimensional requirements.
• Compare individual parts, complete sets, inserts and cosmetic covers.
• Plan measured clearances, machining, fasteners and final installation checks.

Frequently Asked Questions

How should bearing clearance be selected?

Use measured journal and housing/bearing dimensions with the engine builder’s specifications and operating requirements. A brand name or horsepower threshold alone is insufficient.

What do extra-clearance and housing-oversize descriptions mean?

They address different bearing/assembly dimensions. Match the exact size designation to the measured engine and manufacturer reference.

Does head-gasket thickness simply follow bore size?

No. Bore and thickness are separate specifications within a complete sealing and engine-geometry plan.

Do all mount kits include every bracket and isolator?

Review the exact contents and retained components for the chassis/engine/transmission combination. Inserts and complete mounts supply different scopes.

Is a PCV cover the same as a valve?

No. A cover supplies its stated exterior component; a valve or vent fitting has a specific flow and plumbing function.

Are all sleeves in this collection cylinder liners?

No. Tube-fitting sleeves and an adjuster sleeve are also listed. Select each by its actual mechanical function and dimensions.
