• Compatible Lexus applications: GS400 (1998–2000, 4.0L V8), GS430 (2001–2007, 4.3L V8), GX470 (2003–2009, 4.7L V8), LS400 (1998–2000, 4.0L V8), LS430 (2001–2006, 4.3L V8), LX470 (1998–2007, 4.7L V8), SC400 (1998–2000, 4.0L V8), SC430 (2002–2010, 4.3L V8).
• Use part reference VS50592R to confirm fitment on parts databases or with your mechanic.

What comes in the kit and what materials are used?

The kit supplies every rubber seal you typically need when replacing worn valve cover seals. Components are specified for durability in the engine environment and chosen to resist oil exposure and heat cycling.

• 2 x ACM (acrylic rubber) valve cover gaskets for the main sealing surface.
• 8 x NBR (nitrile butadiene rubber) spark plug tube seals to stop oil pooling around plugs.
• 18 x NBR washers to help compress and stabilize the sealing surfaces.
• Materials rated for -20°C to 150°C operating temperatures and tested against oil exposure.

How does this kit help stop engine oil leaks and improve reliability?

Worn or hardened seals often cause oil to escape the valve cover and collect around the engine top. This kit restores contact pressure and material resilience, preventing seepage and maintaining cleaner engine bays.

• ACM valve cover gaskets retain flexibility under heat to maintain sealing force over time.
• NBR spark plug tube seals resist common engine oils and prevent oil intrusion into plug wells.
• Washer set ensures even clamp load and reduces risk of localized gasket compression or distortion.
• Manufactured to OEM-equivalent dimensions for an accurate, even seal.

What should I know about installation and warranty?

Installation requires basic mechanical skills: remove the valve cover, clean mating surfaces, replace old seals with the supplied components, and torque bolts to factory specs. If unsure, consult a qualified technician.

• Kit matches original seal size and shape for straightforward replacement.
• Surfaces must be cleaned of oil and old gasket material before installation.
• Follow vehicle manufacturer torque sequence to avoid warping the valve cover.
• A-Premium provides a 1-year limited warranty on this part (reference VS50592R).

Who is this for? This A-Premium valve cover gasket set is suited to owners and mechanics working on the listed Toyota and Lexus V8 models who need a complete seal replacement to resolve oil leaks, maintain engine cleanliness, or prepare a vehicle for inspection. It’s ideal for do-it-yourself repairers familiar with engine disassembly and professionals seeking OEM-dimension replacement seals without the dealer price.
