FAQ

WILL THIS FIT ALL 1992–2000 GM 6.5L DIESEL TRUCKS?

Yes. MAHLE JV1617 is cataloged for 1992–2000 GM 6.5L diesel truck and van applications. Always confirm by VIN and build details, especially on swapped or rebuilt engines.

IS JV1617 A ONE-PIECE REAR MAIN SEAL?

Yes. This is a one-piece rear crankshaft seal designed to match OE dimensions and sealing materials for the GM 6.5L diesel platform.

DOES THIS SEAL INCLUDE A RETAINER OR GASKETS?

No. JV1617 is the seal itself. If you are doing a full lower-end reseal, pair it with a MAHLE lower engine gasket set such as CS3678A and timing cover components like JV1134 and 46467.

WHAT ARE THE MOST COMMON CROSS-REFERENCE NUMBERS?

Typical equivalents are GM 23503969, Victor Reinz JV1617, Corteco 17271, and Fel-Pro BS40604. Use these only for reference when comparing catalogs.

ANY INSTALLATION TIPS TO PREVENT FUTURE LEAKS?

Check crankshaft endplay, inspect the crank flange, and verify that the crankcase ventilation system is functioning properly. Excess crankcase pressure can shorten the life of any rear main seal.
