MLS Head Gasket:

This Cometic MLS Head Gasket is specifically engineered to replace BMW part # 11121316705, #11121307529, and #11121401351 for the S38B35, S38B36, and S38B38 found in the E24, E28, and E34 M5 and M6 chassis. 

Multi-Layer Steel also known as "MLS" head gaskets are preferred as an aftermarket alternative for high-performance BMW engines, including supercharged and turbocharged models, as they offer better performance than factory gaskets.

The S14B factory head gasket specifications are 93.4mm Bore with a thickness of 0.070 inches.

MLS Gaskets provide maximum sealing performance for high-output engines, without the need for sealants. These gaskets resist shearing forces and reduce bore distortion with their embossing design.

Comprised of multiple layers of stainless steel, they are durable and corrosion-resistant. Ideal for high-performance engines, MLS head gaskets offer superior sealing and can withstand high levels of heat and pressure.

When choosing an MLS gasket for your BMW, ensure compatibility, thickness, and bore size, and follow installation and torque specifications to avoid engine damage.

MLS head gaskets can NOT be used with motors that have O-rings or receiver grooves around the cylinder bores because they require smooth and flat surfaces to seal.

 

Head Gasket Installation Instructions:

  1. Make sure that the engine block and cylinder head surfaces are clean, flat, and free from any debris, oil, or coolant.

  2. Install the head gasket on the engine block and ensure that it is properly aligned. Avoid twisting or bending the gasket during installation.

  3. Place the cylinder head on top of the gasket and install the head bolts or studs in their correct positions.

  4. Follow the manufacturer's recommended torque specifications and tighten the bolts or studs in the proper sequence to ensure even clamping force across the gasket.

  5. After the initial tightening, re-torque the head bolts or studs after the engine has been started and then allowed to cool to room temperature. This will ensure that the gasket is properly seated and compressed.

  6. It is NOT recommended to use any additional sealant on the gasket. Using additional sealant can hinder the performance of the gasket.

Head Stud Kit

S38B35 / S38B36

ARP custom-designed the ARP2000 head studs specifically for the S38B35 and S38B36 inline 6-cylinder engines found in the E24, E28, and E34 M5 and M6 chassis. These head studs provide various benefits upon installation, such as improved clamping force and better sealing of the head gasket, ultimately preventing head gasket failure. These benefits are especially important for high-performance or turbocharged engines that experience increased cylinder pressure, which can cause additional stress on the head gasket and bolts.

S38B38

ARP custom-designed the ARP2000 head studs specifically for the S38B38 EURO inline 6-cylinder engines. These head studs provide various benefits upon installation, such as improved clamping force and better sealing of the head gasket, ultimately preventing head gasket failure. These benefits are especially important for high-performance or turbocharged engines that experience increased cylinder pressure, which can cause additional stress on the head gasket and bolts.

Installation Instructions: 

1. To ensure proper thread engagement and accurate torque readings, clean ALL threads in the block. Chase if necessary with ARP Thread Chaser.
2. Clean and inspect all hardware prior to installation. Look for obvious defects or shipping damages, plus proper fit, length and dimension.
3. If the cylinder head studs protrude into a water jacket, lubricate the block threads of the studs with ARP THREAD SEALER.
4. Screw studs into the block “HAND TIGHT ONLY”.
5. Install the cylinder head(s) and check for binding or misalignment.
6. Lubricate the stud threads, nuts and washers with ARP ULTRA-TORQUE FASTENER ASSEMBLY LUBRICANT.
Then install the washers and the nuts onto the studs and tighten them hand tight.
ARP recommends using the ARP ULTRA-TORQUE FASTENER ASSEMBLY LUBRICANT that is provided with each kit as opposed to motor oil. This is due to higher friction on the studs as well as inconsistencies in the clamping force of the fasteners when motor oil or other low quality lubricants are used.

PRELOAD (TORQUE) RECOMMENDATIONS

7. Following the manufacturers recommended torque sequence tighten the nuts steps 1-3


Step 1: Tighten to 30 ft-lbs.
Step 2: Tighten to 60 ft-lbs.
Step 3: Tighten to 95 ft-lbs.
