Includes the head gasket.

Sometimes you have to take the cylinder head off of your vehicle to diagnose problems, have it rebuilt, or replace a faulty head gasket. It tends to be a fairly labor intensive job, so anytime you can make it easier is definitely helpful.

When it comes time for reassembly, one of the biggest problems is finding quality gaskets and seals. Turner has your solution with this cylinder head gasket kit. With so many gaskets that are one use only to replace, getting them all done at the same time can be made harder by not having everything you need. With the proper, high quality gaskets, your reassembly will go much easier with no need for trip after trip to the local auto parts stores. Intake, exhaust, downpipe, valve cover, and in some applications valve seals will all help to get your engine into top condition.

When it's time to put everything back together, there are some things that should not be overlooked. Most cylinder head fasteners found on European automobiles are a one time use or stretch bolt. To be sure that everything is tightened down properly, it is important to replace them to get the proper torque reading and ensure the longevity of your repair.

Elring is one of the biggest OEM names in the manufacturing of high quality gaskets that are available for very affordable prices. Elring has supplied many automotive names for years with the gaskets that seal your car's components from day 1 so you can rest assured that these components will last for a long time to come!

BMW has an ongoing issue with oil separators freezing in cold weather if driving is done before the vehicle is fully warmed up. There is often a howling noise followed by numerous oil leaks. The crankcase breather valve is used to purge the oil vapor from the engine block into the valve cover. However, sometimes condensation can cause it to freeze, causing the entire oil separator system to fail, crack, and disintegrate. Replace all the components of the oil separator system together to prevent damage to all the aspects of your engine. Level 1 kit includes the following; Oil separator Hose from oil separator to dipstick tube Hose from oil separator to valve cover Hose from intake manifold back to the connector hose Hose from oil separator up to the intake manifold

For Alternator / Water Pump Belt

Hydraulic Belt Tensioner for E36, E46, E39 6-cyl models. This is the oil-filled tensioner that keeps the main drive belt in the proper tension. Over time the piston seals inside allow fluid to leak out. The tensioner becomes frozen or inoperable. Replacement is the best corrective action to take. This can be done during any belt or pulley service or anytime the fan is off the engine.

With their individual brands INA, Luk, and FAG providing exceptionally high quality parts directly to BMW, as well as countless other automotive companies, their history of reliability and variety of offered parts makes Schaeffler a go-to replacement parts provider for all of us here at Turner Motorsport.

This pump features two important upgrades: This pump is engineered with VAC's famous Oil Pump Upgrade kit integrated in its design; this means a stronger gear drive mechanism for much lower likelihood of pump failures on the track. VAC has not only improved the physical reliability of the pump itself but also fit a custom gear with a larger sweep area to the pump mechanism, increasing volume by a welcome 22% An excellent upgrade for Road Race, Autocross, Time Attack, Drift, Hill Climb, Rally, Drag Race, Roll Race & forced induction applications. Lubrication issues are a common killer of BMW engines. The dual-pickup pump is much better than a standard single pickup, but this pump is a dramatic improvement over both.

VAC's S54 Vanos Hub is designed as a direct replacement for the fragile BMW OE Vanos Hub which typically fails due to a broken drive pin. The VAC Hub has an Upgraded Drive Pin design, which is larger in diameter, as well as more material on the outside wall of the pin. In addition, the hub is made from 4340HT Billet Bar and heat treated to the same BMW OE Rockwell Hardness spec. The upgraded design is not only significantly stronger, but the larger diameter Drive Pins also minimize the huge clearance (approximately 1mm) that was in the original design by BMW and reduces the clearance to 0.2mm. This is critical in helping greatly reduce or eliminate the VANOS noise.

Also, this upgraded design eliminates the need for modifying the Pump Ring or having to buy a replacement, which further saves you money!!!
