13108AA111 Subaru COVER ASSY-CHAIN, Price: 468.36$, Weight: 6kg

Engine Timing Chain Cover Assembly for Subaru Performance

Keep your boxer engine sealed, quiet, and clean with this precision timing chain cover . It closes the front of the motor, directs oil to the chain and guides, and locks in alignment between crank and cams. A healthy cover prevents leaks, protects the chain from debris, and maintains oil pressure for long service life and smooth starts ✅.

Why this part is needed

The cover forms a rigid oil-tight barrier, supports tensioner and guide hardware, and houses the front crankshaft seal. Without it, lubrication control is lost, timing stability suffers, and the engine can’t retain proper oil pressure .

How it works

Bolted to the block, the cast alloy shell uses a molded gasket/RTV bead and a front lip seal to keep oil in and contaminants out. Internal passages route oil to the chain and tensioner, while precise faces keep sprockets aligned. It’s the structural “face” of the timing set ️.

What happens if it’s damaged

Expect oil leaks, burning oil smell, rattling on cold start, accelerated chain wear, and potential timing errors. Low oil can trigger warning lights and cause serious engine damage if ignored ⚠️.

Tech tips

Always clean mating surfaces, apply correct sealant pattern, replace the front crank seal, and torque in sequence. Let sealant cure before first start for a dry, lasting seal ⛽.
