Inside a Subaru Boxer H6 Engine

Here’s a look inside Subaru’s boxer H-6 EZ30 engine and how it works! The boxer H6 has two pairs of three horizontally opposed pistons. It also features a timing chain driving dual overhead camshafts. The cylinder heads and block halves sit horizontally, making for a very wide engine with a lower center of gravity than an inline or V6 variant. The EJ30 has both variable valve timing on the intake side and variable valve lift. The VVL uses oil pressure actuated camshaft buckets that pop up to follow a different camshaft profile. The engine uses an all aluminum construction with the exception of a plastic intake manifold and stamped steel lower oil pan. The engine in this video was from a 2005 Subaru Outback that had an overheating issue. No issues were found when fully diagnosed until the engine was torn apart to find clogged coolant passages in the passenger cylinder head, likely due to an overdose of stop-leak additive in the coolant.
