What did you do to or with your CJ today?

[jdcaples]

Temp fix? Love it! Which one are you referring to?

Whistle is still there but not as pronounced so have a handle on the cause. Wanting to get steering coupling done first. Think I'll replace the injectors regardless. Now need to get home after about a 5 hour cruise.

I figured something like Permatex FormAGasket, something non-hardening, but would get into small gaps with a little encouragement.

I've actually fixed my buddies YJ carb vac leak on the trail with a couple sticks of juicy fruit - probably not a permanent fix tho

Replaced steering shaft for one with U-joints, replaced the injectors and put a permatex gasket on the trottle body. Whistle continues.

Now it definitely has to be the intake manifold. Think I'm going to make my own smoke machine for a leak test and see what happens. May just try to temporarily seal it like jdcaples suggested.

Have you gotten another opinion. What do I mean by that? Have you put someone with good ears in the passenger seat to see what they think they are hearing. It could be a bearing squealing like a whistle. It seems to me that it would take a LOT of air to actually make a whistling sound.

It's not constant. It only happens under light load or medium acceleration and between 2120 and 2180 rpm. WOT and it doesn't do it. Never happens when idling. Doesn't happen when parked and revving the engine. There is another higher pitched whistle/squeal that isn't as loud but happens around 2300 rpm. They are both always the same pitch and same volume.

You can sortof control it/make it happen by putting the engine in that rpm band and under a light-medium load. Very distint unlike a bad bearing. It's because of this that made me lean towards a damaged or leaky injector but turns out it is still the same after replacing them all.

Scratch that. I tried different ways this morning to get it to act up and just realized it's not RPM specific but throttle position specific. I was able to get it to act up at slightly different rpms by holding the throttle at a steady position. About a 1/4-1/3 of the way down. The other very high pitched whistle happens when it's about 1/2-2/3 the way down.

With this, I'm wondering if it's the throttle plate whistling? Only thing I can think of that is linked to throttle position and would whistle.

The first whistle is about the frequency of a small screw rattling around in a small glass jar. The other higher pitched one is so high, it's almost not audible.

** did a search on thottle plate/body whistle and came up with a long slew of results. Everyone talking about the same rpm/throttle position so I really think I'm on to something.

Had a tube put in one of my swampers because of a torn bead not sealing up. Anyone run tubes at low pressure off road and regular pressure on road?


Wooly

Wooly,

Internal bead-locks might help... Basically small tubes just around the bead.

Throttle plate shaft bushings. I've had them wear out so they were sucking air.

 

[Neuner]

Checked and re-gapped spark plugs.

Removed throttle body and ground down the sharp edges of the IAC port. Whistle still there but it doesn't appear to happen as often or in the same throttle position. Will have to try some more.

Get a squirt bottle and fill it with VERY soapy water.
Spray all around the manifold and where the water is suck'd in is the leak-The engine's 'pitch' will change also

Carb. cleaner ... same thing. It will suck in and change the way the engine runs, also will make the exhaust smoke.

I called my trucker. As we speak, I have a CJ2a being loaded up and heading to Florida.
On the way down here, the trucker will stop by Illionois and pick up another one, CJ3a .
Then he is going to offload and head to North Florida to get me another CJ3a .

That's what I did with my CJs today.

Cant wait for them to arrive so I can begin restoration.

 

[Neuner]

Replaced a fuel injector connector.

I'm glad that I'm fixing one part at a time because if they all went at once, I don't know if I could mentally handle it.

I got a significant amount of work done on building my cage this week.

 

[Hedgehog]

Nice! I see you've got a bunch of pre-bent and chamfered pipes waiting to be installed. Also, nice.

I bought the Extreme Custom Fab prebent family cage kits. I did the DOM tube upgrade and bought gussets, grab handles, extra tubes and seat belt bungs. It is a nice kit. They notch one side of the tube and make them extra long for fitting reasons. I had to notch the other sides. I plan to tie the dash plates into the frame from the back side of the dash board. I originally wanted a tube to go straight down but there are too many compromises. I couldn't bring my seat forward or use the glove box. I couldn't roll the windows down in the hard doors and it is right in front of the e brake. The dash plate kit I found on ebay. It was a u weld it kit for $45.

Finally took a good amount of time to wash and wax my jeep.





I think it's looking damn fine for 33 years old.

Agreed. Looks awesome! I really need to clean mine up a bit. Ran through something a few weeks ago that left a substance like elmer's glue all over the fenders. I got it off of one of the fenders on Sunday. Took way too much effort. Gotta get some bug & tar remover to try on the rest of it.
