CLio sport 172 engine knocking noise

[DANNYBOY31]

My clio sport was running rough so had two new injectors fitted which cured the problem brilliant i thought. Now I was driving it hard and it started knocking badly it still runs but real rough and sometimes cuts out on tickover what do you think it could be?

Time to get it to a garage/specialist for a proper looking at and I wouldn't continue to drive it about until its been diagnosed... it could be bottom end, it could be a timing slip issue, it could even be something else not quite as nasty. Pretty much impossible to say which without seeing or hearing the vehicle though.

What mileage has it done, where are you from and don't mention to any garage you take it to that you were driving it hard as they'll use it as an easy payday and instantly blame the bottom end.

Right the noise seems to be from the top of the engine and after about thirty seconds disappears on tickover but is still there when you rev it, ideas please?

So you ignored the advice I gave about not running the vehicle until it had been properly diagnosed?

The issue isn't going to magically go away and fix itself with ignorance I'm afraid and you really do need to have the car seen by a specialist that not only knows what they're on with with the F4R Renault engine but one that also has the correct tools to do the job correctly first time... if not you're risking a very expensive bill.

I have a suspicion on whats occurring but without seeing the car it is impossible to confirm or deny but for a start the timing needs checking along with other items such as dephaser condition, belt runs and even the oil pressure needs checking.

I can't really give you any more help I'm afraid.
