Warnings

Tools required

Parts

• Engine oil pan × 1 — Use OEM Maserati part
• Oil pan gasket × 1 — Use OEM Maserati part
• Oil drain plug crush washer × 1 — Use OEM specification
• Oil pickup tube O-ring × 1 — Use OEM specification
• RTV silicone sealant (Maserati approved) × 1 — Use OEM specification

Fluids

Preparation

1. Ensure engine is completely cool (at least 2 hours after last operation)
2. Park vehicle on level surface and engage parking brake
3. Disconnect negative battery terminal to prevent electrical issues
4. Raise vehicle and support securely on jack stands at all four corners
5. Remove engine undertray and splash shields for access
6. Place oil drain pan under drain plug and drain engine oil completely
7. Remove oil filter to ensure complete drainage

Procedure

1. 1

   Drain engine oil
   Position drain pan under oil drain plug. Remove drain plug and allow oil to drain completely (approximately 15-20 minutes). Inspect drain plug threads and sealing surface for damage. Clean drain plug threads with brake cleaner.

2. 2

   Disconnect electrical components
   Locate and disconnect the oil level sensor electrical connector on the oil pan. Disconnect any other sensors or wiring harnesses attached to or near the oil pan. Label connections for reassembly.

3. 3

   Remove front exhaust section
   Disconnect oxygen sensor connectors. Remove exhaust mounting bolts and carefully lower the front exhaust section to provide clearance for oil pan removal. Support exhaust with wire or stand to prevent strain on hangers.
4. 4

   Support engine and transmission
   Position transmission jack under transmission to support weight. Place additional support under engine oil pan area using a block of wood on a second jack. Support must be stable but not under load yet.
   ⚠Engine and transmission weight must be properly supported before removing subframe bolts. Failure to do so can cause catastrophic damage.
5. 5

   Lower front subframe
   Remove front subframe mounting bolts. Carefully and evenly lower the front subframe approximately 3-4 inches using the transmission jack. Monitor engine position and ensure no strain on hoses, lines, or wiring. The subframe does not need to be completely removed, just lowered for pan clearance.
   ⚠️Lower subframe slowly and evenly. Check clearance of all hoses, wiring, and lines as subframe descends.

6. 6

   Remove oil pan bolts
   Remove all oil pan mounting bolts in a crisscross pattern starting from the outer edges working inward. There are approximately 18-22 bolts securing the oil pan. Keep bolts organized as some may be different lengths.

7. 7

   Remove oil pan and pickup tube
   Carefully lower oil pan while monitoring pickup tube clearance. Once pan is down, remove oil pickup tube mounting bolts from inside the pan. Remove pickup tube and O-ring. Inspect pickup tube screen for debris or damage.
   ⚠Oil pan may still contain residual oil. Have drain pan ready when breaking seal.

   Clean all mating surfaces
   Use plastic gasket scraper to remove all old gasket material and RTV from both the engine block mating surface and oil pan flange. Clean surfaces thoroughly with brake cleaner and lint-free rags. Surfaces must be completely clean, dry, and free of oil residue for proper seal. Inspect for gouges or damage.
   ℹ️Do not use metal scrapers on aluminum surfaces. Any scratches or gouges will cause leaks.

   Install new pickup tube O-ring
   Install new O-ring on oil pickup tube. Lightly lubricate O-ring with clean engine oil. Insert pickup tube into engine block opening and align mounting holes. Install and hand-tighten pickup tube bolts.

10. 10

    Prepare new oil pan
    Install new oil pan gasket onto the new oil pan. Apply a thin bead (2-3mm) of Maserati-approved RTV silicone at the corners where the gasket meets the timing cover and rear main seal area. Allow RTV to set for 5-10 minutes but install pan before it fully cures (within 20 minutes).
    ℹ️RTV must be applied sparingly. Excess sealant can break loose and clog oil passages or the pickup screen.
11. 11

    Install oil pan
    Carefully position new oil pan up to engine block, ensuring gasket stays aligned. Start all oil pan bolts by hand, beginning at the center and working outward. Once all bolts are started, torque in a crisscross sequence from center outward in three stages: first to 6 Nm, then 9 Nm, and finally to specification.
    ⚠Following proper tightening sequence is critical to prevent gasket distortion and leaks. Over-torquing aluminum oil pan bolts will strip threads.

    Reinstall oil level sensor
    Install oil level sensor into oil pan. Torque sensor mounting bolt to specification. Reconnect electrical connector and ensure it clicks securely into place.

    Raise and secure subframe
    Carefully raise front subframe back to original position, ensuring all mounting points align properly. Install subframe mounting bolts and torque to specification in a cross pattern. Remove transmission and engine support jacks.

    Reinstall exhaust and drain plug
    Reinstall front exhaust section and torque mounting bolts. Reconnect oxygen sensor connectors. Install new crush washer on oil drain plug and torque to specification.

    Refill engine oil and check
    Install new oil filter. Add 5.5 quarts of Selenia Racing 10W-60 engine oil. Reconnect battery negative terminal. Start engine and check for leaks immediately. Allow engine to idle for 2-3 minutes, then shut off. Wait 5 minutes and recheck oil level. Add oil if needed to reach full mark.
    ⚠Monitor closely for leaks during first start. Shut off engine immediately if any leaks are observed.

Reassembly

1. Reinstall engine undertray and splash shields
2. Lower vehicle from jack stands
3. Double-check that all tools and rags have been removed from engine bay
4. Allow RTV sealant to fully cure (24 hours) before subjecting vehicle to high-performance driving

Verification

• Visually inspect oil pan perimeter for any signs of leakage
• Check oil level on dipstick after engine has been off for 5+ minutes; level should be at full mark
• Start engine and verify oil pressure warning light extinguishes within 2-3 seconds
• Test drive vehicle for 10-15 minutes, then recheck for leaks with vehicle on level ground
• After 24 hours and 50-100 miles, recheck oil level and inspect for any seepage around pan gasket
