Troubleshooting & FAQ
How do I know if my exhaust manifold gasket is failing?
Common signs of a bad gasket include loud ticking or tapping noises from the engine bay (especially when cold), a noticeable decrease in engine performance and fuel efficiency, the smell of exhaust fumes in the cabin or engine bay, and visible soot or black marks around the manifold mating area.
Is this gasket compatible with turbocharged Yanmar engines?
Yes, this gasket is compatible with many turbocharged Yanmar 4JH series engines, such as the 4JH-HTZ, 4JH2-DTE, and 4JH3-TCE models. Always verify your specific model in our compatibility list before ordering.
Does this gasket require any sealant during installation?
No, this gasket is designed to be installed dry. Applying sealants can interfere with the seal and may cause premature failure. Always install on clean, dry, and flat surfaces.
What is the recommended replacement interval?
There is no fixed replacement interval for an exhaust manifold gasket. It should be replaced whenever the manifold is removed or if signs of a leak are detected. It is a good practice to replace it during any major engine overhaul.
Will this fit my Yanmar industrial engine model 4TNV88-B?
Yes, our compatibility list includes several variations of the 4TNV88 engine, such as the 4TNV88-BDHQ and 4TNV88-BDSA. Please check the full model number as fitment can be very specific.
