When you screw in a thread crooked, as long as you don't actually strip the thread right out, there is a lot of the original thread left, and usually enough to hold a fitting. I guess you're taking the sls valve right off this time, so you can carefully thread in a fitting, absolutely straight, and see if it holds. My guess is it will, and I have successfully done this with a steering rack line that my friendly local garage had cross-threaded.
Good Luck! I know that job is very tricky.

got the valve pulled off and yes indeed...one of the holes has messed up threads. not sure if I can re-tap the threads or not but a lot of the original thread seems to be there.

the funny thing is the valve has two different 123 series part numbers but it's a 124 car?????

123 328 0531 and 123 320 0258.

what's with that???

Probably shares similar components from the SLS system on 123 126 and 124, there's very likely little change to the system between makes and models

It's pretty common to find parts on one chassis with part number from other chassis. I've see 115 and 126 part number on 123 parts. A lot of parts are interchangable across several chassis. The 124 and 123 valves aren't interchangable, but probably have some of the same parts that comprise the valve.

here is the valve off my wagon...it's been cleaned up BTW....as you can see, the hard line that I cross-threaded is way too short. i guess it caused me to not get the fitting started perfectly straight with the hole. not any "flex" room.

I'll be getting a longer line and make a wider bend with it.

used my trusty 10mm tap and cleaned up the threads. I put the short line back on and tightened it up STRAIGHT. I'll leave that end attached and put the valve back in and attach the other lines today afterwork and see if the fitting holds pressure.

got it all put back together. looking like re-threading it with a 10mm? tap did the trick

now with my used "ebay special" air cells i'm ridin smooth again

Right on. It always nice when you can fix it simply and not have to spend a bunch of time and money to fix a silly mistake. I hate cross threading stuff. It's a great way to ruin your day.

odie · #25 09-08-2010, 01:42 PM

are you supposed to hear the air cells working? i have not put the flooring back down and i can hear what sounds like the air cells making "squishy" noises when i go over bumps and such.

babymog · #26 09-08-2010, 02:00 PM

It will take a while for the air to work its way out I suspect, ... try lifting the rear of the car off of the ground with the engine idling.

I've never noticed the aforementioned "squishy" noises, but have never driven without the flooring.

kerry · #27 09-08-2010, 03:51 PM

If I have a load in my wagon (ie-passengers in the back seat), when I stop and the load is removed, I can hear a hiss as the pressure readjusts to lower the rear end. I've never heard the sound when driving but it could simply be drowned out by road noise.

Biodiesel300TD · #28 09-08-2010, 03:55 PM

I never noticed any noises from my SLS in my wagon.

odie · #29 09-09-2010, 09:21 AM

i never had noise either on any of my wagons...but again, the flooring is still removed so the tops of the air cells are exposed. just an observation, as the sls does seems to be functioning correctly.

Will do. Thanks.

Good luck!

Thanks for the info. I will check them out. I may have to replace the lines if I cant get them apart.
