hi, i got a ticking noise coming form the top of the engine. It follows the revs, and I think is an injector sound. There is also a small amount of smoke, coming off the top of the engine.

I recently had the glow plugs done, and wasn't there before the repair. But I felt after the G.P. were done, there was a slight lack of power.

Its loudest on cold start up and and becomes much quitter once the engine is warm, but is still there.

Whats going on? :(
 
It could easily be a blowing injector seal, but as you've just had the glow plugs replaced it's worth checking they're sealing properly too.
 
The injector seals are more like valve seats. If they leak they'll need recutting and new crush washers and stretch bolts.

Have a read of this and make your own judgement on how easy you'll find it.

The glow plugs are a taper fit, any dirt could cause blowing.

Stick your head under the bonnet when the problem is happening, you should be able to see or maybe feel the source of the leak.
