My number 5 injector decided to injector decided to stop working so I thought that I would pull the plenum and carry out the water pipe delete whilst I'm at it! To say everything went accordingly to plan would be a lie. For those who have managed to take off and refit a plenum in a few hours, I congratulate you.

 

Anyway, with the injector replaced I carried out the water pipe delete on the plenum and completed the rebuild. All vacuum pipes and electrical connections made I cranked the engine!

 

The engine turned over and then made a horrible mechanical BANG and wouldn't turn over. I have unplugged all the electrical plugs and followed the wiring harness schematic and everything seems to be correct. The only thing that I might have got wrong is the 2 plugs on the back of the engine that are the same, one of them being the VTC plug. Could this be the cause and what damage can it do?

 

I just can't understand why the mechanical bang/engine lock?

 

Please help. A simple enough job gone terribly wrong!!

 

Cheers, Tony.

I wonder, check the cylinder you had issues with. Inspect the plug and the bore if you can.

Ha ha, I'm the one wailing!

Hope you get it sorted Tony :clover:

Oops, walking.

Hope you get it sorted Tony :clover:

 

Cheers for the lucky clover Gary, I might need it yet! Ta.

You did take all tissue out of the plenum holes etc?

Possibly fuel has filled one of the cylinders and effected hydro-locked, take out all of the spark plugs and see if it will turn over then ( fuel pump fuse removed ) and if fuel is ejected out of any cylinder.

Cheers Jeff, I will be having a look in the morning and hopefully this will be my issue. Is this an injector failure or fitting (me) issue?

Could be fuel just spilt over into the cylinder when the injector was out, or the lower injector seal has not seated or was missed and will flood the cylinder when the ignition is switched on ( if so will need injector removing again) or and worse case scenario some foreign object dropped down when the plenum was off but think from the locked engine its fuel.
