If I remove ALDA...
if i remove the ADLA can i remove the over-boost and i just plug the intake manifold line where the banjo bolt is?
i ask because, i've run an engine without the ALDA and am currently and engine bypassing the over-boost by running it to the ALDA. so? i understand what both parts do and i want to know if i have to have at least one "regulator" on boost. everything can go and i can plug the intake manifold or do i have to have something? btw- i like removing crap i don't need. |

If you have no ALDA there's no way to effect overboost protection. If you won't replace the ALDA, you should cap the intake manifold port.

the manifold pressure line tees into other devices, it's possible in addition to the alda, it affects other things. however, it might be just egr stuff, I don't know.

Sixto- I didn't understand what you wrote. I have an ALDA, i bypassed the over-boost. Based on your comment I imagine you say that if i remove the ALDA with the over-boost bypassed then i should plug the manifold. Yes?
Vstech-you sure the manifold line goes to other things? (my EGR is gone) I was rather sure manifold line to over-boost, over-boost to ALDA. please let me know if this is wrong because if it is i obviously got my vacuum lines mixed up after i did my engine swap. |

If you are on a 603, I can take pics of my Federal '87MY one with all the emission stuff missing for testing purposes.
This includes: ALDA, EGR, ARV, etc. I have all vac lines rerouted so car starts properly, shuts off properly, HVAC operates properly, transmission shifts correctly, etc.

That may depend on what car.

so sorry. keep for getting to ad it to my sig.
84 300D or OM617 turbo. 84 chasis and plumbing, 85 engine and transmission no erg, removed the crud on the top of the valve cover, currently have over-boost bypassed to ALDA btw- how do i add a signature? Last edited by Manual Life; 10-03-2010 at 11:28 AM. |

Click on "User CP", you should be able to follow the prompts from there.
If you remove the ALDA, then the over boost protection is a moot point. Just plug off the pressure line as you see fit. The cleanest way would be to remove the banjo bolt on the manifold and simply screw in a regular bolt.

only line to the transmission is from the VCV, the top, not from the cabin vent. the 84 didn't have the wiring to install the 85 amplifier so i did without.
i'm happy with the results of bypassing the over-boost to the ALDA and will leave it that way for now because the ALDA doesn't want to break free. my only real concern is if there IS a risk from remove the ALDA and plugging the manifold line. if there isn't a risk then i will plug the manifold and remove the ALDA after several cycles of lube and brake cleaner. then, no ALDA and 2 less vacuum lines. |

Again, if you remove the ALDA you won't need the pressure line going to it. You can safely plug off that line as you see fit.
Merely being redundant, one more time.

I'm anti Alda. Seen several fail, completely disabling the cars. But then again, that's how I got the cars so cheap. So I guess I'm happy mb put em on. Does anyone have one case where removing alda caused major damage? I've never encountered anything but theoretical worst case scenarios.

Disabling in what way? I've bought several with clogged or otherwise in-op pressure lines from the intake through the switchover valve, made for a very slow freeway entrance, what have you experienced?

Another 85 300dt had really bad Alda. Not safe to drive on Rd cause can't pull in front of people. All the unscrewing of the not never got it to normal power so I took that one off completely too. Fixed the problem. Then my friend bought the 1993 2.5t off here a few months back, that nice one in ky. Those people had put new ip on and all kind of stuff. Surprisingly the Alda was still bad though. Not as bad as my 1993 though You could drive but pulling off the line ws dangerous. We took a screwdriver to it and fixed it good That pos Alda probably cost the previous owner a couple thousand at least for an unneeded ip. The thing about new style Alda is you can't get at nuts to remove without taking intake off. The vacuum nipple curves down in front right where you need to get your wrenches. I'm sure someone with the right tools maybe could do it. Maybe not. A flat head screwdriver, hammer, and channel locks to turn works great though.
