CJ Tea Kettle Squeal at idle and low RPMs

I know this has been posted before but I want to try my luck on the CJ forum. My 79 CJ with the 258 has a "tea kettle" sounding squeal when the motor is warmed up at idle and at low RPMs. I thought it was the belt, so I replaced it. The problem continued and it sounded like it was coming from around the alternator so I replaced it as well. I took it for a test drive last night to get her warmed up and sure enough I idled into the gas station and the squeal returned but not as loud. It only does it every minute or so at idle and then goes back to purring like a kitten. A minute or two later, the squeal kicks in again. Its nothing major other than a major annoyance. Do I not have the belt tight enough or is it the idler pully? Any help would be really appreciated! Thanks!

Had something that could be described the same way...turned out to be low oil pressure related.

The front #1 rocker arm was not getting enough oil, causing the pushrod to basically drill through the rocker arm. While this was happening, it would intermittently squeal like a kettle. Happened to 3 sets on the #1 only. Once I put in the new Melling 4.0 HV pump...no more low pressure, no more tea kettle like squeal, no more pushrod or rocker damage.

In my experience, a slightly loose belt will usually squeal when you rev a cold engine, not at idle with a warm engine.

You might try using a 3' chunk of garden hose as a stethoscope to isolate the noise.

Not sure what the "squeal" sounds like, but I had a small vacuum leak one time that would sort of make a tea kettle sound.

CAPT, I want to change the oil pump anyways and as a matter of fact that is one of the next things on my list. I've only had this JEEP since August and I am slowing doing things my way as I have time. I appreciate the feedback though. Its so weird though because she will sit and purr like she is supposed to and then a slight squeal that might last 20 seconds and then right back to the purr. A few minutes later, the squeal returns and 10-20 seconds goes by and she is back to normal.

Good call Matt, and I will try that to see if I can pin point the problem. I'm no mechanic, I'm a JEEPER and I'm learning.

Mine did that a while back and it turned out my intake/exhaust manifold bolts were loose.

Where the manifold connects to the block?

I had a similar problem years ago. It was my carberator not tightened down all the way at the base. But the squeal would get louder with rpm.

I'll give that a try and see what happens. Its just strange because in my opinion it does seem to come from the passenger side towards the front of the motor.
