Seal It Up: Complete Engine Gasket Sets
Leaking oil, coolant, or vacuum? Old cork gaskets dry out and shrink over time. At Old Car Parts NW, we stock complete NOS and NORS Engine Gasket Sets and individual seals to keep your fluids where they belong.
Materials Matter
Valve Cover & Oil Pan: We carry traditional cork for purists and modern rubber/synthetic blends for better sealing on warped surfaces.
Intake & Exhaust: High-heat composite gaskets to prevent blowouts.
Rear Main Seals: Rope seals for early engines and neoprene updates for later blocks.
Breath Easy: Oil Filler Caps & Breathers
The Oil Filler Cap does more than just plug a hole—on vintage cars, it is often a critical part of the crankcase ventilation system.
Ventilated vs. Sealed
Breather Caps: Many pre-PCV engines use a "Breather" style cap with wire mesh inside to filter air entering the engine. If this clogs, you blow seals.
Sealed Caps: For closed PCV systems.
Style: Chrome, painted, and "twist-on" or "push-on" styles to match your valve covers correctly.
