Intake Manifold Vacuum Hose

[matt]

Another reason it's a bad idea... say you're out in the middle of nowhere and your fiberglass comes apart or the resin melts or something... you get a new intake manifold and you need to hack it up again before you can install it!

This is the same reason I am against 320i brake boosters... what if you break down away from home and need a new one? you'll have to borrow or buy a tap and a file and modify your new booster. I just have to find another used or new iX booster and bolt it right in.

This situation is actually worse, because if that fails, you'll be off the road.

But whatever, it's not my car. Do what you want, I just needed to put in my two cents for the next guy that reads this.

Um what is the failure rate of a brake booster??


Just asking since I have never seen it in my entire life on any car, even the money pit 944.

Well the 944 uses an ATE booster. I think that's why it didn't fail. :mrgreen:

The mode of failure is usually the diaphragm letting go if you let a bad MC leak fluid into the booster over time. I don't think I've ever heard of a booster rod breaking. I could understand if someone welded it and didn't use proper welding techniques. But otherwise, the rod ain't going nowhere.

It is rare that a booster would actually fail, but it happens. Usually they leak vacuum around the input nipple. (lol I said nipple)

(lol I said nipple)

I said that in my head before I read it. lol

Failing is extremely rare indeed. And when they do, its gradual thing. The quality of the weld is moreso my worry.

[FredK]

Yeah I hear you. That's why I filed it and threaded it. Well actually I used a die to form M12x1.5 threads first, so that my filing would be centered. Also, I didn't have a welder at the time I did it. Now I do though. :mrgreen:

Yea I threaded also. I didn't think it was a common thing even though I did't pick up a wrench till 10 years ago.

If something is going to leave me stranded it's prolly gonna be that weak ass 325i E36 gearbox. Damn those things are fragile.

Update:

After seeing the quality of my fiberglassing (my first time), I decided to get another manifold and try to fit on a brake booster from a Mk2 VW golf in there instead of messing around with it. Both are on order...

If someone wants a hacked up manifold, send me a pm ;)
