Cummins gasket FAQ
Which Cummins gasket fits my engine?
Read the engine model from the Cummins engine nameplate or valve cover, then match it to the engine applications listed for each gasket below. Where the OE part number of your old gasket is known, match the OE number first; it is the most reliable check.
Are these genuine Cummins parts?
No. DIESEL IZUMI sells aftermarket replacement gaskets and seals made to the listed Cummins OE references. Cummins names and part numbers are used for reference only.
What should I send if I cannot find my Cummins part number?
Email info@dieselizumi.com with the Cummins engine model, engine serial number, a photo of the nameplate and the old gasket next to a ruler. We will confirm fitment or quote a part that is not listed.
Where do Cummins gasket orders ship from?
All DIESEL IZUMI orders ship from Guangzhou, China. Delivery time depends on the destination and the shipping method chosen at checkout.
