The BMW N52 engine was deisgned with a crankcase vent system that relies on a heated oil separator valve to separate vapor from the liquid oil. Under ideal circumstances, the oil vapor would pass back into the intake and get burned up during normal combustion. The liquid oil would follow a path back down into the oil pan and be reused. This system is environmentally friendly but plagued with problems. The heating elements can fail or oil and carbon particles can block the oil separator valve. With no escape, the oil will continue to pool and collect in the valve cover or make its way into the combustion chamber leading to excessive oil consumption, blue smoke from the exhaust, idle and running issues. These issues are worse in colder climates where the freezing temperatures create an oil sludge condition that is impossible to clear. The plastic hoses can become brittle and crack which leads to vacuum leaks and oil leaks. Thankfully, the CCV is replaceable on the early N52 engines (2006 and some 2007 models) and should be inspected during a major service and any time the valve cover is off. Oil can also back up into the throttle body, which is easier to check than the oil separator itself. Later N52 engines do not have a serviceable oil vent as it is integrated into the valve cover and not a separate part.

This is a kit containing the oil separator, the vent hoses, and the intake manifold gaskets that are done during a typical oil separator replacement. Complete kit includes:

11617531423, Genuine BMW oil separator

11617559530, vent hose

11157522931, oil separator hose

11157567802, return hose

11157537701, extraction hose

11617547242, intake manifold gaskets (set of 6)
The intake manifold must be removed to access the oil separator so new profile gaskets are included. We also recommend (but not required) a new oil separator fitting on the intake manifold because it's one of the heated elements that vaporizes the oil as it enters the intake.

The oil separator can be replaced on its own but for a complete service we also recommend replacing the oil separator hoses and cleaning the valve cover. Any valve cover or intake manifold work should include a new oil separator valve.

This kit fits the following BMWs:
10/2005+ E90 BMW 325xi 330xi - Sedan
10/2005+ E91 BMW 325xi - Wagon
10/2005+ E60 BMW 525xi 530xi

E30 M3 2.5 liter Stroker Kit for S14 Engine - (NO LONGER AVAILABLE) ...

T#:3397

Part#: 11211316979KIT

No longer available

One of our most popular items! We have been selling our S14 stroker kit since 1993. Since then we have sold HUNDREDS of this exact kit, and have received incredible feedback from our customers. RELIABLE Horsepower is our goal. Our E30 M3 2.5L Stroker kit uses factory BMW Evolution III parts to convert the stock 2.3 liter engine into the Evolution III 2.5 liter engine. Increasing the displacement and raising the compression yields much more torque: +50 ft/lbs @ 4000 rpm. With a stock head our 2.5 kit will make over 225 hp.

Our kit includes everything you need to convert your 2.3L into a 2.5L. We highly recommend upgrading the intake and exhaust system to allow larger 2.5L engine to breath. Call for more details and for "custom" packages. We can set you up with any other engine components you may want to replace (tensioner rails, chain guides, oil pump, etc) at the same time. For your benefit, we carry all these items (and at a great price).

The Turner 2.5 liter S14 Stroker Kit includes:

Genuine BMW 2.5L crankshaft w/ bearings, nut and spacer
2.5L head gasket
Bottom end gasket set
Turner/Conforti Custom 2.5 Liter Computer Chip **Only available from us! This is what sets our kit apart from the "other guys kit"
Wiseco 2.5 forged piston set w/ rings (11.25:1 compression)
Genuine BMW rod bolts and head bolts (we suggest Genuine fasteners for reliability)

The factory VANOS exhaust hub on the S54 engine is known to develop excessive play where the drive tabs interface with the oil pump disk. Over time, this imprecise fitment causes a back-and-forth rattling motion that can result in the tabs shearing off inside the engine, risking catastrophic damage or complete engine failure. Unlike other aftermarket solutions that require full VANOS disassembly, retiming, or replacement of the oil pump disk, the Turner Motorsport S54 VANOS Hub Upgrade offers a smarter approach. Our bolt-on fix eliminates the common failure point without opening the VANOS unit or disturbing engine timing.

Our solution involves removing the worn tabs from your stock exhaust hub and installing our precision-fit replacement, which is precision-machined from 4340 steel and hardened to meet OEM specifications. Designed using 3D scanning and CAD modeling, the Turner Motorsport VANOS Exhaust Hub Upgrade provides a tight, interference-free fit into the oil pump disc, completely resolving the issue without unnecessary labor.

Features & Benefits:

Direct bolt-on solution for S54 VANOS oil pump drive tab failure, preventing potentially catastrophic damage to engine internals Precision-machined from high-strength 4340 steel and heat-treated to match OEM specifications Designed using 3D scanning and CAD modeling to ensure precise fitment within the OEM oil pump disc Engineered to eliminate the play that exists between the exhaust hub and oil pump disc from factory Backed by extensive real-world testing and our lifetime replacement program!
