Description

TOPRAN 624 801 is a timing chain oil jet designed for BMW rear timing chain diesel engines.

It sprays pressurised oil directly onto the timing chain assembly to help reduce friction, chain stretch and guide wear. A blocked or damaged oil jet can lead to poor lubrication and premature timing chain failure.

Often replaced during timing chain repairs or engine rebuilds.
