When the integrated PCV diaphragm on your B58 engine tears, it does more than just create a loud whistling noise under the hood. The ruptured valve allows the engine to pull raw crankcase oil vapor directly into the intake manifold and combustion chambers. By the time you diagnose the PCV failure, your engine has likely been burning oil for hundreds of miles. This thick oil vapor heavily coats the spark plugs in carbon, leading to rough idles, hesitation, and misfires—even after the PCV vacuum leak is fixed. Furthermore, the extreme heat trapped near the firewall on the B58 architecture naturally degrades the ignition coils over time. This ultimate refresh kit is the definitive "while you're in there" solution. It utilizes the highly sought-after Genuine BMW PCV fix kit (allowing you to repair the valve without replacing the entire expensive valve cover) and pairs it with a fresh set of OEM spark plugs and ignition coils. We also include a brand-new Genuine BMW corrugated CCV breather hose, as the factory plastic line is notoriously brittle and almost always snaps when you attempt to move it out of the way during the PCV repair. Kit Includes: (1) PCV Valve Repair Kit (Replaces OE # 11121025447) (1) CCV / Crankcase Vent Hose (Replaces OE # 11157637521) (6) NGK Spark Plugs (Replaces OE # 12120040551) (6) Turner Ignition Coils (Replaces OE # 12138643360)

Fix the whistle, replace the brittle vent hose, and flush out the contaminated oil. This kit pairs the highly sought after PCV fix with a premium Liqui Moly Top Tec 6600 0W-20 oil service to give your engine a completely clean slate. When the integrated PCV diaphragm on your B58 tears, it causes a massive unmetered vacuum leak that pulls raw oil vapor directly into the combustion chambers. This doesn't just create a loud, embarrassing whistling noise at idle—it causes poor air/fuel mixtures that force raw, unburned fuel past the piston rings. This blow-by heavily dilutes your engine oil, destroying its ability to properly lubricate the bearings and timing chain. Fixing the PCV using this Bremmen repair kit (which saves you from buying an entirely new valve cover) is only half the battle. You absolutely must get that compromised oil out of the crankcase. This comprehensive service kit includes the Bremmen PCV repair cap, the fragile corrugated crankcase breather hose that almost always snaps during the repair process, and a complete premium oil change. We've included Liqui Moly Top Tec 6600 0W-20, which carries the strict BMW LL-17 FE+ approval. This ultra-modern, low-friction oil ensures instant lubrication to the turbocharger upon cold start while maximizing fuel efficiency. Paired with a fresh OEM Mann oil filter, this kit completely reverses the collateral damage of a PCV failure. Kit Includes: (1) PCV Valve Repair Kit (Replaces OE # 11121025447) (1) CCV / Crankcase Vent Hose (Replaces OE # 11157637521) (1) Liqui Moly Top Tec 6600 0W-20 Engine Oil - 7 Liters (BMW LL-17 FE+ Approved) (1) Hengst Oil Filter Kit with O-Rings (Replaces OE # 11428583898) (1) Oil Drain Plug with Crush Washer
