Squeeking noise from engine.

[ciaran1380]

Theres a awful squeeking noise coming from the engine, sounds like Ive a supercharger! Im looking at the belts being the main culprits. Changed them both 2K ago and they have been fine since. Has anybody had this before?

Changed the exhaust also for a Ktec janspeed SuperSports with a decat. Have to say, brilliant exhaust, very impressed with it. However Im getting the emissions warning light on the dash, took a while to appear but I expected it. What I didnt expect, was it to begin flashing usually when its cold, or Ive been sitting in traffic or stuck behind a coffin dodger. I presumed this was due to it just running on the rich side. But I changed the plugs there a week ago and #1 was running much richer than the other 3 cylinders, also my MPG is fluctuating from 21 MPG to 36 MPG and this is same driving style etc? Is this and the exhaust related?

Also I read that its hard to get much more out of the f4r engine, is this true? If Honda get 170 + from a B16 then surely more can be gained from the 2L renault?

^^How much money you got? it is do-able but not cheap

depends on if its worth spending the money on it to get more power, or just buy another car with more power! Ive the usual mods, induction kit and straight thru with a de cat, so I suppose the next step is mapping it? Maybe RS tuner?

I don't know the cost of things but i doubt you will see any real gain this side 2k.

Noise could be PAS pump.

Is the squeek present all the time e.g when just letting the engine idle? or just when revved? Were the tensioners changed or not when the belts were done?

Tensioners on the TB were changed, Guy in Renault told me I dont need a tensioner for the aux as they never change them? Its there when Im driving, not when Idling I dont think. I was thinking it could be the gearbox, but its doing it in every gear it seems. The PAS is losing fluid, not alot, maybe 100ml every 3 or 4 months, I just keep it topped up, It did run down to the point the pump was making interesting noises but those noises aint the same as Im getting now. Its getting me paranoid as I dont want a belt letting go! Is there anything to look for on the tensioner to indicate its going? I really do not fancy doing it again so soon, its a pain in the arse to get at.

Is your lambda sensor knackered perhaps!? Running rich, Mpg fluctuating, emmission light coming on.

The tensioner and idler pulley on the aux belt should be changed every 36k miles. Not worth not doing it because if it fails it can cause the timing belt to jump, ruining the engine.

 

[ciaran1380]

bit of an update to the noise, used a screwdriver up against the timing cover and could hear the belt flying around and a faint squeek, its intermittant at idle but when i driving its noticeable. Its definatley around the aux/timing belt area as the noise fades further away i go. any ideas? Might pull off the timing cover and have a look if everything is still aligned.

not so much knackerd but its not getting the reading its looking for as its decatted!
