Cylinder head flow (Engine - Td5) (page 2 of 2)

A tapping towards the right hand side of the cylinder head diverts oil supply from the cast-in groove down to a stub pipe which attaches to a feed line to the vacuum pump. An hydraulic tensioner is located below the vacuum stub pipe which receives oil through a small hole in the side of the tensioner body to force a plunger against a plastic faced adjuster shoe for timing chain tensioning. Oil from the vacuum pump is returned to a port in the timing chain cover via a short hose which connects to stub pipes at both ends using spring clips.
