FAQ

Will this kit fit LS7 or dry‑sump LS3 engines?

No. The M29517 kit is not compatible with LS7 or dry‑sump LS3 applications found in Grand Sport Corvettes. It is intended for standard LS pump configurations.

Can I install the O‑rings without removing the oil pump?

While it is possible to replace the O‑rings with the pump still mounted, removing the pump provides better access and ensures a clean seating surface, resulting in a more reliable seal.

What torque specifications should I use when re‑installing the pump?

Follow the vehicle manufacturer’s torque values for the oil pump mounting bolts, typically ranging from 8 to 12 Nm (70‑110 in‑lb). Over‑tightening can distort the pump housing and damage the new O‑rings.

How often should the O‑rings be inspected or replaced?

For high‑performance or high‑mileage engines, inspect the O‑rings at every major service interval (approximately every 30,000 miles). Replace them if you notice oil leaks, pressure drops, or visible hardening.

Is the rubber material compatible with synthetic oils?

Yes, the synthetic rubber compound is formulated to be chemically compatible with conventional mineral oils as well as modern synthetic blends, ensuring long‑term durability.
