Engine Gasket & Seal Kit for Subaru Boxer Engines

This complete gasket and seal package restores tight, leak‑free operation across your Subaru’s flat engine. It seals the head-to-block joint, cam carriers, valve covers, intake/exhaust, water pump, oil pump, and both crankshaft and camshaft ends. Built from OE-grade materials—MLS head gaskets, graphite-coated paper, and Viton/NBR lips—it withstands heat cycles, pressure, and modern coolants/oils. Perfect for rebuilds, head work, timing service, or any oil/coolant leak fix. It keeps compression strong, fluids separated, and emissions clean .

Why you need it ✅

To stop oil and coolant leaks, maintain combustion pressure, stabilize temperature, and prevent contamination that wears bearings and sensors.

How it works

Multi‑layer steel head gaskets clamp between block and heads to seal combustion and coolant jackets. Elastomer radial seals ride on crank/cam surfaces to control oil. Formed gaskets conform as you torque, filling micro‑gaps for long‑term sealing.

What happens if it fails ⚠️

Expect oil spots, coolant loss, white exhaust, overheating, milkshake oil, misfires, catalytic damage, and in severe cases spun bearings or engine seizure. Small leaks grow—fix early.

Tech tips ️

Check flatness, clean mating faces, follow torque/angle specs, replace TTY bolts if required, lube seal lips, align dowels, and pressure‑test cooling.
