This replacement gasket from Elring is perfect to prevent any further oil leaks.

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!

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.
