Strange click click click

[FTA1995]

Interesting clicking noise, only on warm-up at less than 40 deg.
I think its a lifter, but it almost sounds like the water pump impeller. I guess its possible that there is a burr or something that rubs the impeller housing until it warms up and expands away. It's not rod knock, its not spark knock, its not an injector, an its not in my head

Hits about 95F noise is gone completely with no other symptoms.

Oil pressure is good, oil is new and i think that might be the issue. Using mobil 1 full synthetic, 10w-30. Used it before, no problems before.



I'll get a video up in the next hour if i can.

Second part of the video its much more clear sounding. I think it might be the PS pulley bearing. Its NOT the alternator bearings or brushes. I do have an A/c deleter in, but the click isn't resonating from that area so much. Temp was about 15 deg. when i did this. about 1200 rpm idle due to temperature.

Ideas?

Damn thats a tough one. At first I thought it was a rocker just needing an adjustment, but the second part it does not sound muffled at all. Sounds external. I dont know about the water pump. Hmmm Im stumped.

[FTA1995]

yea im really not too sure.

I THINK it might be in the power steering, im going to take the belt off and let it run for a few seconds.
No sound means it is an accessory.

Does ANYBODY recognize this noise?

I'm not rushing it that much because theres going to be an inch of ice today after the storm.

What else could expand enough when warm to get rid of the problem?

If i find out the PS is doing it, im going to pull the pump nad play around with it.
re these pumps rebuildable, or am i pretty much screwed for a new one?

Let it cool off and use a mechanic's stethescope. It's much easier to pinpoint the source of the noise.

[FTA1995]

Yea, stethoscope.

I just use a long screwdriver to the ear.

Already tried, couldn't find ANYTHING.

List to check:

Main bearing noise (please kill me if so)

Idler pulley noise (easy fix)

Power steering noise

check for loose components

FTA,

I saw your post earlier and was going to suggest runnin' her up without the serpentine belt, but I see you posted afterwards that you were going to try that. It's o.k. to run it like that for a minute or two, if you even need to run it that long. It's how I found my bad A/C clutch pulley bearing.

If the noise goes away, obviously it's one of the belt driven components.....

Call it a hunch, but I'm guessing it will be the bearing in the idler. Doesn't sound like main bearing noise to me---so be optimistic!!!

Good luck!

[FTA1995]

I think it's the idler.

BUT then again, I just recently installed an AC pulley to replace the compressor, hopefully that wasn't defective.
We'll see soon enough, i'll post some results tomorrow after the test.

[FTA1995]

Good news,

Belt is off, no more noise

Now the REAL question is....

What is teh origin of said noise....

back in a few, more testing

[formula_gramps]

Belt is off, no more noise

Hey that is good news!!!

When you get the belt back on, you could spray a little WD into the bearing of the idler. It should work its way in and I don't see how you could do any harm if you're careful.

Any change in the sound after that would be a 98% chance you found the culprit.

I'm sure I don't have to tell you not to spray any in the A/C clutch bearing though.......LOL!!!

[FTA1995]

haha yep, i pulled the idler apart, the bearing is shot and seated improperly, so it was wobbling a little and causing the clicky clicky. AND the tension spring is sticking a bit.

aha I don't have A/C anymore, just another blank pulley.

I'm going to need a new assembly, there's just too much wrong to bother fixing.

Off to eBay to find a part.

[formula_gramps]

FTA,

All things considered, you lucked out.

Of all the likely culprits that would make that noise, that idler is probably the cheapest fix.......

That's good! I like happy endings.....LOL.

[FTA1995]

Cheapest, yes, but for my broke self, this still is a pain.

The funny part is, now that i look at it, i think this from when i hit a rabbit about a month ago.

I ned to find an assembly for cheap, ill post something in the trade/sale area
