Could be the lift pump is knackered they can tap when they fail.
Not going to be a blockage in an injection line, injection lines don't block.
Could be but start simple.

Vac pump is notorious for tapping on these.

I had exactly the same thing that sounded like a leaky injector ... turned out to be the head gasket gone at the back of the block... no oil water mixing etc just gasses coming out under compression... when you say you've checked the head gasket how di you do that ?? cheers

If it is the head gasket this is what happens. I have had 2 in during the last fortnight doing just this.

Here is a picture of how the gasket splits and just let's out exhaust gasses.

Was just wondering whether the op managed to find and sort the ticking. Without an outcome, the thread isn't complete, lol

My 300tdi sounds awful to me and taps away (its not the lift pump or lift pump) but ive showed it to a few people who,ve owned a 300tdi and they reckoned it sounded fine!

So first t hing i suppose is to listen to another one before deciding its noisy.

But i still cant help thinking theres something wrong with it.

Tonks, currently got a 110 300 with HG blowing out the back of number 4, at the very back middle of the engine.

In your experience have the engines needed head work?

It just throw a new 3 hole gasket on and be done with it??

Just weighing up the job you see

Well here's mine on tick over. If you listen very carefully, you'll hear a slight ticking noise coming from the drivers side of the engine. The noise on the other side is the air filter housing wobbling about.
