Intake Manifold for 1996 Aurora

[waateva]

Hi!  I just recently joined after looking around online for some answers to my car issues.  

I have a 1996 Aurora that I have owned for over 10 years that has worked great!  Besides some basic fixes and routine maintenance, I have had no issues, that is until recently.  A few months ago I had acceleration issues, which seemed to be fixed by replacing the plugs and wires.  About a month and a half ago, I had a very similar issue come up that was resolved by replacing the coil pack.  Well, two weeks ago the same thing started happening.  When running, the engine ran very rough, the Check Engine light was flashing, and would kind of 'glug-glug-glug' as well.  I brought it in to be fixed, had the O2 sensors replaced but that was the furthest the mechanic was able to go so he referred my elsewhere, where they figured out that the pressure relief valve (?) on the manifold had completely degraded and that they would need to replace the whole intake manifold, which will run me $1000+ for parts and labor.

As I looked around online, I saw a few threads discussing similar issues (including on here) and some seemed to agree that the single valve could be purchased for much, much, cheaper than the whole intake manifold.  My questions is how intensive something like that would be, as I am not really too much of a handyman, and if it would be worth purchasing that single part and seeing if they will possibly even just replace that?  Any help would be appreciated, the articles I mentioned are linked below!

Welcome.

I think this is what you are after?

$1000 is a total ripoff. I can sell you whole intakes all day long for $50 plus shipping, and it takes 30 minutes for a good mechanic to change them, an hour for someone that usually does not work on cars. No special tools required, fuel line is released by your hand. Removing the power steering pump to access the backfire valve is also easy, remove belt, one bolt holds the power steering pump on down behind it, the belt is the hard part, don't let it slip down.

I agree, Rockauto has a new intake for under $250, add $20 for gaskets and a couple hours wrenching and its all done.

I think that it is!  Thanks for re-directing me to something more in-depth but, now the problem of finding a place to do the work at that isn't freezing comes next!

Also thank you Randy and genedjr for giving me an idea on the level of work required.  I checked a few local scrap places and one does have a full intake manifold, however, it might just be better to purchase a new one since the price doesn't seem too much different.

If you have a self service junk yard, that would be the cheapest route.  But, I would check the old one carefully.  Unless someone took a hammer to it they are pretty tough.

Would it be wise to bring someone who can examine the faulty fuel relief valve on it?  It seems that the valve isn't too expensive brand new, which I could just replace on the recycled manifold.

OK, let me make sure I understand.  You are taking about the backfire valve in the end of the manifold?  I am about to tackle that as well.  I have decided to replace all the o rings and seals involved in the intake.  Everything is cheap and its only a matter of time before they start failing.  Now, that valve is pretty easy with the manifold off.  I took one apart at the junk yard just to see and when I do mine (probably two weeks from now) I will post a how to.

BTW - that is another use of upullit junk yards - figuring out how to do a repair - if you break it there, no big loss.
