This ARP head stud Kit is designed for the BMW S14 B20, S14B23, S14B25, S14B27 engines found in the E30 M3. Installing ARP head studs can provide several benefits, including increased clamping force, improved head gasket sealing, and greater overall engine strength. This is especially important in high-performance and racing applications where the engine is subjected to increased stress and higher temperatures. Before installing ARP head studs, it is important to properly clean and prepare the engine block and cylinder head mating surfaces. It is also recommended to use ARP Ultra-Torque Fastener Assembly Lubricant during installation to ensure proper torque and clamping force. 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.

Most people will probably experience a head gasket failure at one point or another during vehicle ownership. The signs of a failed head gasket are easy to identify: Milky oil as the coolant mixes in, loss of performance, and sweet smelling, white smoke coming from your tailpipe. It usually happens when the engine is overheated or has a number of miles on it. Replace yours and get your engine running again.

This Athena Cut Ring Head Gasket is specifically engineered to replace BMW part 11121316714 for the S14B20, S14B23, S14B25, S14B27 engines found in the E30 M3. Factory OEM & MLS head gaskets are only engineered to handle a limited amount of cylinder pressures before they start to leak, causing a range of issues, including engine overheating, loss of power, misfires, and in severe cases, catastrophic engine failure. Athena-SCE Cut Ring Head Gaskets are uniquely designed to handle increased cylinder pressure caused by power modifications, making them the recommended choice for applications making 16+ psi. Design: Athena-SCE's gasket body is composed of Motorgasket, a reinforced material developed by Athena's R&D department. This consists of a steel core covered with two layers of asbestos-free aramid fibre and offers excellent thermal and mechanical resistance without compromising its ability to adapt to mating surfaces. To ensure maximum sealing under all conditions, a silicone bead is also applied to critical sealing areas, such as oil and coolant passages. The AISI 304 stainless steel cooper rings bite into the aluminum head, providing maximum sealing around the cylinder bore and optimizing engine performance, even on engines with nitrous and/or turbo applications that exceed 2 bar boost.

A great replacement to a damaged chain or one that may have been misplaced out of a timing belt kit.
