Brand: Volvo Penta
Product Type: Oil Pipe Retainer — Plugged Side (OEM)
System: Engine Lubrication / Oil-Level Assembly
Position: Plugged side (not interchangeable with dipstick-side retainer 3887580)
Supersedes: 3583624 (plugged-side position)

What This Part Does

The 3887581 secures the oil pipe at the plugged-side position within the engine lubrication assembly. Volvo Penta split the earlier shared retainer (3583624) into two dedicated parts: 3887580 for the dipstick side and 3887581 for the plugged side. The two are position-specific and not interchangeable — each is identified separately in the Volvo Penta lubricating-system diagram.

Compatible Applications

Confirm your complete engine model, suffix, and serial number against the Volvo Penta lubricating-system diagram before ordering. Retainer arrangements vary by production break within the same engine family.

Always verify against your engine serial number and the correct lubricating-system diagram. The retainer arrangement changed at a production break — earlier engines used 3583624 in both positions.

Serial Number Notice

Earlier D4 and D6 engines used 3583624 in both the dipstick-side and plugged-side positions. Later service parts split that into 3887580 (dipstick side) and 3887581 (plugged side). Confirm your engine's production suffix and serial number before ordering to ensure you have the correct position-specific retainer.

When to Replace

• Retainer is bent, distorted, or cracked
• Corrosion has weakened the retaining function
• Oil pipe is no longer held securely at the plugged-side position
• Retainer was damaged during sump, dipstick, or lubrication-system service

A damaged retainer can allow unwanted movement of the oil pipe and associated fittings at the plugged-side location.

Installation Notes

• Install 3887581 on the plugged side only — use 3887580 at the dipstick-side position
• When servicing this retainer, inspect neighboring retainer 3886957, nipple 3886951, and guide 22456382 while the assembly is accessible
• Confirm the retainer is correctly seated and securing the pipe before reassembly
• Do not substitute 3887581 for 3887580 — they are different parts for different positions

Parts Desk Insights

The most common ordering mistake with this part is selecting 3887580 instead of 3887581, or vice versa — both appear in the same diagram and are similar in appearance. Always confirm the position (plugged side vs. dipstick side) using the lubricating-system diagram before ordering. If both retainers are being serviced at the same time, consider inspecting the full assembly including 3886957, 3886951, and guide 22456382 — it's the same access point.
