When to Replace
Replace this gasket whenever the turbocharger oil drain or outlet connection is opened during service. The gasket compresses under torque and should not be reused. Also replace if the existing gasket is leaking, hardened, cracked, heat-damaged, or visibly deformed.
Installation Notes
- Clean both mating surfaces thoroughly before installing the new gasket
- Inspect the oil drain flange and fasteners for distortion or damage
- Do not reuse the old gasket
- A clean, flat sealing surface is critical for reliable sealing at turbocharger oil connections
- Follow the Volvo Penta service manual torque specification for your specific engine and serial number
Service Interval
Replace whenever the turbocharger oil drain connection is opened — during turbo removal, oil system service, or any repair that disturbs the oil drain flange. Refer to the Volvo Penta service manual for your specific engine model and serial number for full turbocharger service intervals and procedures.
Technical FAQ
Can I reuse the old gasket?
No. This is a crush-type plane gasket that deforms under torque. Reusing it risks oil seepage at the turbo drain connection. Always install a new one.
Does this fit all Volvo Penta turbocharged engines?
It covers a very wide range of Volvo Penta diesel engine families, but fitment is not universal. Always confirm by engine serial number and the correct parts diagram for your specific engine.
What happens if I skip replacing this gasket?
A reused or damaged gasket at the turbo oil drain is a common source of persistent oil seeps after turbo service. It is a low-cost part that can prevent a high-cost repeat repair.
Parts Desk Insights
This is one of the most commonly overlooked gaskets during turbocharger service on Volvo Penta diesel engines. The turbo oil drain connection runs hot and under constant oil pressure, which means a compromised gasket will seep — often showing up as an oil smell or minor drip that gets blamed on other components. If you're doing any turbo work, budget this gasket into the job. It covers an unusually wide range of engine families, so if you're not sure whether it fits your engine, have your serial number ready and we can help confirm before you order.
