EVIL ENERGY GM LS Rear Sump Low-Profile Retro-302-2, 81073 Fit Oil Pans Swap GM LS LS1 LS2 LS3 1967-1992

Q: Will this rear sump oil pan fit my LS1, LS2 or LS3 engine?

A: It is designed for most Gen III/IV 4.8L, 5.3L, 5.7L, 6.0L and 6.2L wet‑sump LS‑based engines. Confirm that the engine is not a dry‑sump application, the crankshaft stroke does not exceed 3.62 inches and the chassis has sufficient rear‑sump clearance.

Q: Is this a Ford 302 rear sump oil pan?

A: No. This product is for Chevrolet Gen III/IV LS‑based engines. The product references 81073 and a 302‑2‑style configuration, but it does not fit a Ford 302 small‑block engine.

Q: What is a rear‑sump oil pan?

A: A rear‑sump oil pan places the deepest oil reservoir and pickup toward the rear of the engine. It is selected when the chassis provides space behind the crossmember and a front or deeper factory pan would interfere with surrounding components.

Q: How do I choose between a rear‑sump and front‑sump LS oil pan?

A: Choose according to the chassis geometry. Use a rear sump when there is usable space behind the crossmember; use a front sump when the rear is obstructed and the chassis has adequate space at the front.

Q: What comes with the LS rear sump oil pan kit?

A: The kit includes the cast‑aluminum oil pan, gasket, baffle, pickup tube, drain plug, oil filter stud, oil passage cover and mounting hardware. The windage tray, dipstick, dipstick tube, filter, oil and installation consumables are not listed as included.

Q: How do I remove and change an LS oil pan?

A: Drain the oil, remove the filter and any components blocking access, then support the engine as required before removing the pan fasteners. The pan must be worked around the pickup, and some chassis may require the engine to be lifted or removed. Install a new gasket and pickup O‑ring during reassembly.

Q: Why is there low oil pressure after changing the oil pan?

A: Possible causes include an incorrect oil level, pinched pickup O‑ring, pickup tube that is not fully seated, blocked oil passage or internal contact. Shut the engine off immediately and inspect the lubrication system before restarting it.

Q: How much does it cost to replace an oil pan?

A: The total cost depends on labor access rather than the pan price alone. Crossmember interference, exhaust removal, engine lifting, windage‑tray modification and damaged sealing surfaces can significantly increase labor time, so obtain a quote based on the actual vehicle and swap configuration.
