MLS Head Gasket:

The Cometic MLS Head Gasket is a high-quality gasket designed specifically for the S85 V10 engines found in BMW vehicles. This gasket is intended to replace the original BMW part #11127837460, and is designed to provide superior sealing performance compared to other gaskets on the market.

The gasket features a multilayer steel (MLS) construction, which provides increased strength and durability, as well as improved heat resistance and reduced cracking. This makes the Cometic MLS Head Gasket an ideal choice for those looking to upgrade or replace their existing head gasket on their S85 V10 engine. Additionally, the gasket is precision engineered to ensure a perfect fit, and is made from high-quality materials to ensure longevity and reliability.

The S85 factory head gaskets specifications are 92mm Bore with a thickness of 0.027 inches.

MLS 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 MLS 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 recommended to not use any additional sealant on the MLS gasket, as it is already coated with a Viton rubber sealant. Using additional sealant can hinder the performance of the gasket.

Head Stud Kit

This high-quality kit is designed to replace the factory head bolts BMW# 11127583116, making it an ideal solution for high-performance driving enthusiasts looking to unleash the full potential of their engine.

Crafted by ARP, an industry leader in fastener technology, this Head Stud Kit boasts a remarkable tensile strength of 200,000 psi, ensuring that the studs can withstand extreme pressure and loads. This results in exceptional durability and reliability for your engine, providing you with peace of mind during even the most demanding driving conditions.

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.
