FAQ
Will M-3958165 fit my 2003–2007 5.9L Cummins?Yes. It’s specified for 03–07 Dodge Ram 2500/3500 with the 5.9L ISB. Verify by ESN if your engine has been swapped or rebuilt.
Is this an OEM Cummins part?
No. This is an aftermarket OE-style replacement by Interstate-McBee. It cross-references OEM Cummins 3958165.
Does it require sealant or RTV?
Only where the Cummins service manual specifies (typically at corners or joints). Do not over-apply RTV as it can affect sealing.
What else should I replace while I’m in there?
Inspect the oil pan for warpage, replace pan bolts if stretched, and consider a fresh drain plug/seal. Check front/rear main areas for leaks.
