Rare sound

Hello everyone, I am new in this forum and I
would like you to shrink a little hand I tell you I have a cytroen zx 1.9dy 160000 kilñometers that from a little and noted or it is my mania that a small noise mixed with the typical of the diesel engine it in rementi and only in a hot motor or that I see It is constant but it does not disappear is something rather intermittent sounds normal and ace Clap Clap Clap or something and again and again and Buelta to repeat

me .

Welcome to the companion forum, I do not believe that the Route of Marras is something as serious as the crankshaft caps.

If it is a Diesel ZX, the noise is very likely to be the alternator strap tensioning roller, assisted steering pump, air conditioning compressor.

This sound makes it only slowed down and disappears as soon as you accelerate slightly, it is as if the engine is more hoarse, it appears especially when you are parking (assisted direction) or when you put the air conditioning at idle.

The way to see if I am right is very simple, you start the car, you open the hood and you get in front of the nose looking at the straps, you will see a black plastic roller that keeps the tense strap, if you put the air or tour the steering wheel with the engine at idle, the roller vibrates, the belt trembles and the noise appears.

All the best.

Thank you for answering but it is nothing of that, I hope it has no assisted address and the other straps and tensioners and disassembled and put the car in motion and the noise persists today and had to spend the car by travajo and read Casado 120kilometers and the nois Listen to that if only when you squeeze around 1500 or a little more and stop approaching me that it could be an injector but threw a cleaner and nothing if it is true that he had about two days that the car lost me a little the relief thing that never I ever did for that I also thought of the
Saveis injectors as I can put in some way the sound taxed on the web and so you listen to it
.

Well some more idea
couldn't it be any injector or something that seems to you?

The sound of a connecting bullshit sounds like when you give a hammer to the engine. It is a fairly strong and sharp sound.

The noise will then do it in two circumstances:

1 when you accelerate the top engine in point, it has to sound a lot.

2nd When you ask for the engine for idié, (recover in second, get out of the ramp of a garage ...)

if it is injectors, the car is going to throw white smoke by the exhaust (diesel without burn) or very black smoke when accelerating (half burned gas and sohllin).

If you had a broken injector, or a broken piston, the engine would go in three cylinders, and that is easy to detect because I slow down as if it were a gallop horse, apart, the engine heads much more than normal. (It moves much more than it is normal to idle)

to see if all the cylinders work, the easiest way is to start the already slowed engine, loosen one by one the nuts of the injectors, and observe how the behavior of the engine changes.

The 1st is loosen, the engine must start to head, accelerate strong and if you listen to the noise because you squeeze the nut and continue with the 2nd, the 3rd and 4th.

If the engine fails of an injector or a piston, when loosening the nut corresponding to the damaged cylinder, the rhythm of the engine does not change, and by accelerating strong, it does not make the noise that brings you head.

If you really have a crushed connecting rod, what you will touch to do is remove the oil, disassemble the crankcase, take out the pacifier out of the oil because maybe it hinders you and change the caps games one by one.

To do this, you put the cylinders 1 and 4 below, marks the hunning hat of the 1 to not put it up, disassembled it, remove the cap, mount the new cap and reappriets.

Then you follow the same steps with the 4, then you turn the engine and make 2 and 3

. What you have to be careful is not to exchange the connecting rods and grease the caps before mounting them.

The tightening pairs of the connecting rod screws will have to look for them or ask them when you ask for the caps in a spare parts house or in the Citroën.

Another thing, if you disassemble any caps, you observe that the crankshaft is scratched, do not mount it. Because it will have to rectify the crankshaft and for that you have to remove the engine from the car and disassemble it whole. I hope it's not so serious.

Greetings and whatever you tell us something.
