Default Brand new UIM self destructs in less than a year.

About a year ago I replaced both gaskets and upgraded the manifold (supposedly). So just yesterday the car left me standed with coolant in the oil. Mechanic says the manifold rotted away and not only let coolant mix with the oil but coolant got in the MAF and a couple of other sensors. Hopefully he can save the sensors.

Just wondering if anyone else with the 'improved' manifold has had subsequent problems like mine did ???

which part number did you buy? was it the OEM one or was it the autozone? was it a delphi or what?


No it is not abnormal for these to fail often though.

I would think it is abnormal to fail in just a year, though. I'd be looking into a warranty claim on that little sucker.

Get the dillon UIM from here. And I'd like to know how coolant got in your MAF sensor. That'* a real trick.

Before the car is taken apart, get a good macro pic of the date of manufacture from the top of the intake...

Eeven better yet, look at the date...If it was replaced a year ago it should have a late 2004 through 2005 date on it... If it does not it was not replaced... And oil on the MAF... I'd like to know how the hell that happened...

As well it sounds a lot like there may have been a lower intake gasket issue..

There is something here that I am seriously not trusting...

And on another note, I have never seen an intake fail in 1 year, same goes for the lower gaskets

The whole thing struck me kinda funny too. He said that it happens to all bonnevilles and that he will hold the failed manifold for me. I will call him again 1st thing tomorrow and inform him that I have the serial # of the manifold and I will go back to the mfr to discuss a refund. Let'* see if he sweats.

Am I skeptical of mechanics? Heck yeah!

Did you repair this yourself the first time, or did you have someone else do it?

I have some sleeved ones ready to go now. PM me if you're interested. Regardless of what happens, I wouldn't reassemble it with a stocker, for just the reason you're posting.

I have a theory on this one. When the upper manifold is removed...I believe you will find the EGR stovepipe will not be in the lower intake manifold seated properly as it should be.

This missing stovepipe might be lodged in the upper manifold or was suppsed to have been replaced with a smaller diameter that came in the new manifold kit and someone forgot to put it back in.

I saw one case where a manifold was replaced, and unknowingly to myself and the person the pipe was missing. Bob Dillon then received the core manifold back and asked why we sent a sleeved one back. The base of the manifold gets erroded quickly when the hot exhaust gases beat on it directly. This can cause a premature failure by superheating the base of the composite manifold.

Please let us know about the stovepipe. It SHOULD be firmly in the lower intake manifold.

Here is our reassembly picture. Stovepipe is not there.
