I don't have the capability of posting a photo of this crushed can...i.e. no photobucket or similar account.

I did not know the can was only as resovior to raise or lower the headlights with the engine off. Makes sense however.

Not much if a gear head so I am not sure what your comment means (joke/tech talk.)

If anyone else has a photobucket type account and would post the photo for me... shoot me a private message with your cell number or email address and I can send a photo of the crushed can still in place under the hood.

You also have storage space here, not much but you do have some. Go to User CP - Pictures and Albums and create an album then upload and share your photos.

You hit reply button. Then look lower than the submit reply tab. See manage attachments tab? Hit that and you are into the pic adding stuff... one other possibility for crushing cans. Maybe your car really sucks...

YEP..I would say that vacuum can is a P.O.S.

Just ANOTHER part that some jack @ss bean counter got their hands on and had to make cheaper.

hope you are returning the crushed cans back to the suppliers and getting a refund

then they can send them back to their supplier and complain to them.

Fredtoo was joshing. By "bigger cam" he meant a camshaft designed more for high-rpm performance, which will produce less manifold vacuum because it will have more valve overlap, which means a greater percentage of each piston cycle with both intake and exhaust valve partially open.
Someone else may explain it better, but I think that's the gist.

I was going to blame your crushed vacuum reservoirs on a quantum black hole.

Went to take hoses off that annoying campbell soup can to organize and the nipple broke off and fell into the tank. This keeps happening more and more to me, cheap reproductions for big money. Bought a new turn signal lever for $90 (cheapest one I could find) and after installing I notice the text already wiped off of it. Put some money in and get an original, there's a few for sale on ebay.

I think we had the same tank, mine was paper thin.

Parts back in the day were made to last!

I see that it is time for this once again here on the Corvette Forum.

Keep in mind this is only my opinion and you may agree with it or may not.

My "95% rule"...and it goes like this.

95% of the time....95% of the companies that reproduce parts .....reproduce them to 95% of original standards. And it takes 95% of MY TIME to finish out that last 5% so I can make the part even work as designed...if at all.

So...I feel that this problem is NOT going to go away...simply that there are people who budget shop and buy crap and are willing to live with crappy parts. And it is almost impossible for a company to make stuff right and charge for it accordingly when there are cheap crappy parts out there that people prefer to buy becasue they are cheaper. Think about it.

When they started making furniture out of pressboard with a cheap fake @ss veneer on top of it and stapling the furniture all together is where it kinda started. Then furniture looked good form a distance and people settled for that...and would not pay for really good furniture that was made out of wood.

So..when they can make a part over seas for a few cents...and charge a dollar for it. Guess how many of them they can replace before they even being to effect their profits. because...THEY know you will give up and stop trying to get a part replaced and go buy another one from someone else and the process will often times repeat itself.

AS stated..just my thoughts on this.

I agree with about everything you stated, DUB. But, the repro industry works very hard at making their parts LOOK like the real thing....but ON THE CHEAP. Meaning, that they cut corners on material strength, heat treatment, type of material, etc, etc just to get folks to buy inferior products that don't work. It's playing on the "buyer beware" philosophy; and folks looking to save money, dive right in.

Yes, when the part is the cheapest one out there, the buyer should be suspicious of its quality. But, it's a coffee can! Right? Well, an older, stronger coffee can. What is made today won't hold up.

But, one would think that anyone making (or buying) these things would at least try one to see if the d@mn thing will actually function in a car!! If they had just hooked it up to the intake vacuum on ANY vehicle it would have crushed in minutes! That maker has to have some skin in this process. Just because it's junk made in a foreign country shouldn't let the maker/buyer and subsequent sellers off the hook.

With the system as it is, when parts do not do what they should, we need to get money back and notify their corporate headquarters that they are selling JUNK. If the proverbial 'squeaky wheel' makes enough noise, they might finally take notice. But, if you can't make a dent in their "wallet", it will just continue as is.

P.S. These parts may be made in foreign countries; but the businesses that initiated the ordering may well be good 'ol Americans...

My '69 has a canister; my '73 uses the front cross member (a pipe with brackets) as the storage device. When did GM go back to using a canister? Does the '80 have the pipe cross member and is it possible to use that cross member on the '80? My guess would be that somewhere between '73 and '80 GM realized it was cheaper to put the canister back than to seal weld the cross member.

1980-1982 have the canister. It was more to save weight than to save money, as the Corvette dropped 150 lbs from 79-80, including that heavy front crossmember.

'Richard454', '7T1vette', and others who are aware that what is being supplied to us needs to be carefully inspected.

I can say this is that I will call and complain to the companies who sell the stuff that fails. About 95% of them. My comments it fall on deaf ears and they tell me that they sell hundreds of them a year and I am the first one to complain. Go figure!

I have even went as far to start some thread to let you all know to BE AWARE of what I have found!. And YES...these companies that provide services and parts are U.S.A. based and I can tell you that they are more than likely NOT going to do anything about it due to they do not want to effect their bottom line. And they count on either the ignorance of the buying public or the fact that they have been accustomed to buying junk and will live with it.

Trying to get this trend to swing in the other way is NOT going to happen due to so many people just do not care and live with it. It deals with QUALITY CONTROL and I can tell you stories about some very well known companies in the Corvette industry that manufacture parts that DO NOT watch what is going on.

SO EVERY TIME I gets parts in...my stomach gets in knots due to I HOPE that what I am getting will actually work and be able to be installed.

I am done with my rant on bad parts because I know...or hope...that we are now aware of it and hopefully people who do care...make a big of enough 'stink' about it that things can change. But I doubt it due to I feel that those of us whop do CARE are outnumbered by those who just do not care.
