Installation Guide

  1. Disconnect the battery and allow the engine to cool completely before beginning work.
  2. Remove the exhaust manifold and cylinder head cover according to your engine's service manual.
  3. Clean all carbon deposits from the combustion chamber, valves, and piston tops using appropriate cleaning tools.
  4. Remove old gasket material from all mating surfaces using a gasket scraper, ensuring surfaces are clean and flat.
  5. Inspect all surfaces for cracks, warping, or damage that may require machining or replacement.
  6. Install the new gaskets from the kit in the correct positions, following the service manual's torque sequence.
  7. Apply a thin, even layer of gasket sealant only if specified by the manufacturer for certain surfaces.
  8. Reinstall the cylinder head cover and exhaust manifold, torquing bolts to factory specifications in the proper sequence.
  9. Reconnect all hoses, wiring, and components that were removed during disassembly.
  10. Reconnect the battery and start the engine, checking for any exhaust leaks or unusual noises.
  11. Allow the engine to reach operating temperature and inspect all gasket areas for leaks.
  12. Re-torque cylinder head bolts after the first few hours of operation if recommended by the manufacturer.

Troubleshooting & FAQ

Q: How do I confirm this gasket kit fits my Volvo Penta engine?
A: Check the compatible engine models table above to verify your engine model (MD5A, MD5B, or MD5C). You can also cross-reference the OEM part numbers 876341 or 875561 with your engine's parts manual.

Q: When should I replace the decarbonizing gaskets?
A: Replace these gaskets during every decarbonizing service or whenever you remove the cylinder head or exhaust components. Reusing old gaskets can lead to leaks and reduced engine performance.

Q: Can I reuse the old gaskets if they look undamaged?
A: No, gaskets are designed for single-use only. Even if they appear intact, they compress during installation and will not seal properly if reused, potentially causing exhaust leaks or coolant leaks.

Q: What are the signs that my decarbonizing gaskets need replacement?
A: Common symptoms include exhaust leaks, visible soot around gasket areas, loss of engine power, increased fuel consumption, or coolant mixing with oil. If you're performing decarbonizing maintenance, always replace gaskets as preventive maintenance.

Q: OEM vs. Aftermarket?
A: This listing is an aftermarket replacement part (not an OEM component). We build to OEM specifications using comparable-grade materials. Production is done in an ISO9002-certified facility, and each batch is inspected for consistent performance.

Q: How fast do you ship and how much does it cost?
A: We offer fast global shipping—typically 5–15 days worldwide—and standard shipping is free. Expedited options are available at checkout depending on your location.

Q: What is your warranty and return policy?
A: This product includes a 1-year warranty against manufacturing defects under normal use. If something goes wrong, contact our support team with your order details. Returns are accepted within our standard return window (unused & in original condition); please see our policy page or reach out for instructions.

It holds so many plugs!
Size: 6.5 Ft, Color: Black
I am using this to plug all of my Christmas village pieces in. I haven't used it yet, but it's going to be great to keep the plugs all in one area.

well designed
I have two of these. The number and orientation of outlets has fit all my needs. I haven't needed the USB's yet, but I'm glad they are there. The thin plug and off-center angle are very useful. One is in use under my three seat power reclining sofa, guitar multi-effects, and a couple lamps are plugged into it. The other is in a drawer powering the air pump, power filter, lighted hood and heater for the aquarium on top of the dresser it is in.

Needs better hardware
Size: 6ft Cord, Color: 20W_Black
Yoooooo great product but what is with the comically tiny screws? Actually installing this on the underside of a wooden desk is near impossible unless, of course, you are in fact a Disney princess and in charge of a team of handy-dandy mice all with #0 Phillips head screwdrivers and 5/32" drill bits. They drill, you hold, kind of thing.
