Troubleshooting & FAQ
How do I know if my turbo oil drain gasket is failing?
Common signs include visible oil leaks from the connection between the turbocharger and the oil drain line, a smell of burning oil in the engine bay, or low oil levels without other obvious causes.
Is this gasket a direct fit for all Volvo Penta D4 and D6 engines?
Yes, it is designed as a direct replacement for the OEM gasket on all standard Volvo Penta D4 and D6 series marine diesel engines. Always verify your part number is 20707685 or 860105.
What is the recommended replacement interval for this gasket?
There is no fixed interval. This gasket should be replaced whenever the turbocharger or oil drain pipe is removed for service, or if a leak is detected during inspection.
Can I reuse the old bolts when replacing this gasket?
It is best practice to use new fasteners or ensure the existing ones are clean, undamaged, and torqued to the manufacturer's specifications to ensure a reliable, leak-free seal.
