noise when the engine is warm

[leandro89]

it is a mercedes a class 180cdi 2000 109cv when the temperature of the car is around 80? going above 2500 rpm you hear a noise type beat both on that gear from a standstill, both with the clutch to the bottom of that to the crowds.
according to you, what can? be?

+ or - to locate the area?
the cio? in the head, in the tour right left?

[leandro89]

unfortunately in the class to the engine ? infognato and the noise, it seems to me that it does in the head

[cinqueturbo]

As it happens to many mjet I would say the injectors..

You can feel the heartbeat of where it comes from with a stethoscope to the motors ? a very simple tool, but effective and costs a load of crap.

I, too, think of them, and if you have them..... Good luck

But you can't figure out if ? the sound of a knock or a lack of lubrication or other

said so' ? almost impossible to give a help, could be everything, if it were the injectors to beat you should have or smoke; hence excessive or a zoppicamento of the engine.

fumosit? almost zero even at full load and the machine ? mapped, if it were the injectors should not do so always? instead of doing it when I reach about 80?

[fil89n]

The map on this can fool you.. Just that you have a afr high and does not smoke, even with the injector to -5 correction..
I honestly, I find that doubt with a simple diagnosis by 3 minutes. Then you have a 4-cylinder, in order to have big failure, you should have a couple that limp..
If ? poor lubrication you have to make the test more? invasive and expensive, because of the position of the engine..so it is best to start from the check things out "easy"..
If it was cold I would think a tappet or to the chain, but from the hot usually decreases, not increases

[ugoboss]

if ? mapped the first thing to do ? put it back gold and then try it out.

hello to me ? happened a similar thing at the end after various tests and disassembled the engine the problem was caused by the pump of oil ke to a certain number of laps lost pressure and made a noise in the distribution

You can? stay warm could drop the prex motor oil from the pump, and then you find the same noise that would be cold if the tendicatene was nailed
