It is a little bit colder these days in montreal...
This morning I started the 1998 Rodeo (3.2/ Automatic/ 50K miles) and between 1900 and 3000 Rpm I hear a whistle comming from the engine. It cleared away as the engine warmed up. I did not push it at all so I can't tell if there is a power loss or not. First day it does that.

Is that the first sign of a leaking intake gasket?
Could it be a stupid idller that starts to rock not roll?
Anybody has ever seen this before?
Should I simply raise the volume on the radio or leave the truck in the driveway for a week to punish it?

Thanks

How much to get that Holly seal replace.
Is like 50$ or more like 1000$
Is that a week-end mechanic kind of job or more like an open heart surgery?

I just use that new link at the bottom of the main page that brings you to speedy car parts. I can find the price for it but no drawing.
Does anyone know where i could find an exploded view of my engine (to see witch part I need)

Thaks for the answer, I will keep watching it for the next days and I will probably try to do it myself at christmas time.
The only thing I don't understand is the newton meter thing, It sounds like a cookies brand name. :lol:

Thank you again

I know brake cleaner is pretty rough for some materials. I know it can melt some rubber compounds. Is it going to eat my seal?

I openend the hood this morning and gave it some gas,
Dam its noisy, I am surprise a stupid air leak could be so loud.
Could a bad iddler make noise when cold only?

OK,
I sprayed some carb cleaner at the base of those aluminium vertical manifolds, no RPM change,
I tryed to move all pulleys, idller wheels... where the belt travels and I found that the water pump pulley can move a little bit in and out. Not very much, but it is not as stable as the other one. Is that normal !!! it is not moving very much...

Tomorow, I will try to spray some WD40 on it to see if I get a new tone...

Temperture is fine (always in the first half)
The noise only last for 3 minutes. Hapens once a day when cold and slowly goes away. I can park it for the entire day and it does not do it when I leave the office at night.
I was in a trafic jam last friday, temperture was fine.
Tomorow morning I will spray some WD40 on the pump itself. Probably between the center bolt and the rubber seal that turns with that small wheel.

It is loud (probably arround 70db).
I will also try to cover the pump with a piece of cardboard to try to isolate the source.

How do you spray the carb cleaner on the inside of the manifold?
It's easy to do on the outside but the inside...
Does the failure always happen on the outside of it?

My guess is that the bearing or the blades inside the water pump are rubbing against something but as temperture goes up, metal expand and everything is fine again. Thats until the temperture goes bellow like 35 F and the cycle restart making me go crazy.

This morning I removed the belt and ran the engine for 20 seconds, No noise. Put the belt back... noise
Sprayed a little bit of WD40 on the beaaring: change of tone. I did not put too many, it goes every where. So if there is a long term side effect to the WD 40 on the belt I will let you know shortly :oops:

Just an iddler: That makes sense I could not figure out why the bolt was not turning with the pulley. That a good news, it mean I will be able to fix my problem for just a few dollars.

So thats a good truck it always gives a warning when something is broken and you can fix it with your pocket change. ( I am not waiting for your comments on this one, just let me dream) :wink:

THANK YOU EVERYBODY

Its a canadian 6$....
Bad news, it is still whistling a bit, the bender pulley is still stiff (no side to side play) but it does not spin very long when I give it a quick shot.

step 1 will be the belt anyway, it is craked a little bit.
