The timing chain in any vehicle can begin to stretch and rattle over time. This is a common issue, and though BMW says it is a lifetime part, most enthusiasts decide to change them. If you need only the timing chain instead of a kit, ECS Tuning has your replacement. This is a direct fit replacement for any broken or stretched chain. A great replacement to a damaged chain or one that may have been misplaced out of a timing belt kit.

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.
