Auto Parts Prodigy Crankcase Ventilation PCV Valve & Hose Kit for 2006–2007 BMW N52 (E90/E91/E60/E61) — Oil Separator, Direct-Fit

Complete crankcase ventilation replacement kit engineered to restore correct PCV function on 2006–2007 BMW N52 engines, including oil separator, return hoses, and pressure-regulating valve for a direct-fit repair.

If your 2006–2007 BMW with the 3.0L N52 engine is showing rough idle, elevated oil consumption, or persistent vacuum-related codes (P0171/P0174), worn PCV components are a common culprit. This Auto Parts Prodigy kit supplies every hose, seal, and valve needed to replace aging crankcase ventilation parts on E90, E91, E60, and E61 chassis without cutting or custom fabrication. Parts are manufactured to match OEM routing and dimensions so you can complete the repair with common tools and a clear installation guide.

How does this kit fix rough idle and oil burning?

The kit replaces the leaking or brittle hoses and failing PCV valve that allow unmetered air into the intake or let oil escape into the intake tract. Restoring controlled crankcase vacuum reduces lean-running conditions and prevents oil from being drawn into the intake system.

• Precision pressure-regulating PCV valve limits crankcase vacuum to the designed 0.5–1.0 psi range.
• Reinforced, heat-resistant hoses eliminate vacuum leaks and oil seepage common with aged rubber lines.
• Oil separator and return hoses capture and route blow-by oil back to the sump, not the intake.

Will this kit fit my BMW N52 engine and replace OEM parts?

Yes — the set is engineered specifically for 2006–2007 BMW models equipped with the 3.0L N52 engine (325i, 325xi, 330i, 330xi, 525i, 525xi, 530i, 530xi and Z4 on E90, E91, E60, E61 chassis). Components are manufactured to match OEM fitment and replace common BMW part numbers.

• Direct-fit hoses and connectors match original routing and lengths—no trimming required.
• Replaces BMW part numbers 11617531423, 11617504535, and 11617522923 equivalents.
• Includes O-rings, grommets, and a guide with torque specifications for correct installation.

What materials and performance can I expect from these parts?

Materials are selected to resist high underhood temperatures and chemical exposure so the system remains durable through normal driving cycles. The valve uses machined brass internals for consistent operation; hoses are reinforced rubber rated for elevated temperatures to avoid cracking or swelling.

• Heat-resistant composite hoses rated for typical engine bay temperatures above 300°F.
• Brass-backed pressure valve offers stable regulation vs. cheaper plastic alternatives.
• Durable seals and grommets to maintain vacuum integrity and reduce warranty-style callbacks.

How long does installation take and what tools do I need?

Most DIY mechanics complete the swap in under an hour with basic hand tools. The package includes a step-by-step installation guide plus recommended torque values so you can follow a reliable sequence for quick, professional results.

• Estimated install time: about 45 minutes for a competent DIYer.
• Tools: standard socket set, screwdriver set, and pliers—no specialty tools required.
• Pre-formed hoses and included O-rings remove guesswork and prevent rework.
