A New Sound! NOT A GOOD ONE!!!

UGHHHHH yet again... Here we freaking go.... I think i have taken the car apart now 4 times in the last month. Anyways... I started the car this morning and heard this:

Any ideas before i tear the thing apart again? I can't see anything hitting or rubbing right now which kind of leads me to believe that it's under the timing belt covers :( but i want a second or third opinion. This car is testing me to my limits right now!

Alternator bearing or power steering pump. It sounds like a bad bearing somewhere IMHO.

[ThePaintballGuy]

any way of checking it easily?

Josh

take a stethoscope and find where the noise is coming from

[lowered97a4]

take the engine belt off then listen then u know for sure if its in the timing belt area

[ThePaintballGuy]

ok, i will do that. Can you take the belt off w/out removing the core support? (That would be so awesome if you could.

Josh

[lowered97a4]

ya u can get it off might have to go underneath the car to get it off the lower pulleys its gonna be a pain

[lowered97a4]

or might have to take off couple of other things but maybe not pulling the front off

[ThePaintballGuy]

ok... well i guess i am going to head out and try and fix this POS again....

Thanks for the help guys.. i will let you know what i find.. in the mean time any more ideas would be great.

power steering pumps make noises when you turn the wheel.

[ThePaintballGuy]

why do you say that?

Josh

[Overboostin]

man, you have no luck with your car! good luck, I hope it gets worked out.

btw, I don't think its power steering related.

[ThePaintballGuy]

alternator. enjoy.

Fun... Well i will be taking the serp belt off and if it doesn't make that noise anymore then that will be the first thing to check... how would i check just the alternator?

Josh

[ThePaintballGuy]

It's not the powersteering pump. I went out and started the car and tried turning the wheel and the noise stays the same... it doesn't change at all. Only time the noise changes is if i rev the engine.

Josh

[lowered97a4]

just take the belt off if u can thats what i would do then just listen

[ThePaintballGuy]

Ok, i am going to head out right now and do that.

Josh

Then its the alternator IMO

I'm about 90% sure its your clutch fan hitting your bi-pipe. the mounts for the pipe on the belt cover break easily and it gives the pipe just enough room to hit the fan. if you have a plastic oem pipe, the fan will tear a hole in it, I found that out. I ended up having to buy a APR bi-pipe because of it.

if its hitting, you won't be able to see the point of contact, so look at the fan blades for damage and feel the bi-pipe with your hand to see if its damaged. if thats it, use a razor blade to trim up the back edge of the blades so it has some clearance

[ThePaintballGuy]

OK, it's the serpentine belt tensioner pully. It spins a lot and sounds like crap. Alternator sounds fine and spins w/out a noise.

Josh

Oh and btw, i took the front end off (or mostly off). Everything is hooked up still but everything is unbolted so i could pull it far enough forward to take the belt off... and i did it in 30 min flat! HAHA So the good thing about all this is a have gotten REALLY good at taking this car apart!

[lowered97a4]

good to hear u found something other than the timing belt

[ThePaintballGuy]

Yeah me too... i really didn't want to have to take it that far apart.

Josh

[ThePaintballGuy]

Can anyone suggest any other parts i should replace while in there?
