Hello,

There are no timing marks on this engine.
The engine is locked in place with special tools.
Sealey and other manufacturers sell these, kit VS4770
Please see image below.

This kit consists of 2 camshaft and 1 crank shaft locking pin. A chain tensioner retaining pin is also included.

To access the locking positions for the camshafts the fuel rail will need to be removed.
Only the exhaust camshaft is locked in place. The intake camshaft is driven off the exhaust camshaft via an internal gear. Once done you will then need to lock the crankshaft into place by using the supplied locking pin and engage it at the transmission bellhousing, locking the flywheel.

Once done you can then remove the vibration damper and timing chain cover to access the timing chain.

Please let us know how you get along.

Cheers, Boris
