I've recently had to replace the injector seals on my Vito.

In the process one of the stretch bolts sheared and in order to get to it the rocker cover had to come off.

We got it out and all the injectors, bolts and seals were replaced, started the engine and all was hunky dory.

Gave it a few revs in neutral and suddenly there was a loud knocking sound as if one of the injectors was having trouble firing.

Having checked all the connections we came to the conclusion that a bit of dirt had got in somewhere and this morning we replaced the offending injector.

Now the engine runs and sounds like all 4 injectors are firing at the same time, just not in the right place - this has resulted in a loud knocking sound.

Just wondered if someone can help us if this has happened to them or has any clues as to what we can do?

Thank you.
