Hey guys, well the cold snap is almost over, but I can't find the time to finish up during the week. I'll probably finish up this weekend.

I'm going to replace the injector o-rings as suggested. But, I had one other "issue" that I wanted to ask about.

During dissassembly, I "creased" one of the fuel lines to the rail. Basically, I tried to bend it too much and creased it. Is this gonna' leak under pressure? They appear to be plastic.

If I need to replace it, where would I get the line?

Thanks for any suggestions...

Well, I believe that you can add me to the list of manifold failures... :(

On a routine check of all vital fluids today I noticed that the coolant was a tad low (lower than my last check). Looked around the intake manifold and sure enough, there is a small puddle of coolant on the lip of the lower intake manifold behind the throttle body. Looks almost like its coming from around the bolt closest to the edge of the manifold. Is this where everyone else is seeing the leak? I'm going to go see if I can't get a good picture of the location to post.

Be back in a few...

Back with pics:



**EDIT** Ok... What'* wrong with the image posting???
**EDIT2** NM... I'm a dumbass...

Looks like you misspell .jpg...

You used .jgp.....

Yeah...I just tried your URL with .jpg and it works....

Looks like your failed in just about the same place as mine.... How many miles are on yours...

I just finshed mine up tonight... I used the blue loctite on all the fasteners to the lower mainfold. I never did find a place with injector o-rings... I got tired of looking... They were still spongy...

Just got to flush/fill coolant...

Geez what a stupid mistake... Oh well. Fixed now.

I've got exactly 37,385 miles on my bonnie. I sometimes have a heavy foot, but try not to break the tires loose (too expensive to spin them), and never do I put my foot into it until it is up to full operating temperature.

This has to be a rising problem. Any of you guys that frequent ClubGP seeing any of the GTP'* are having the same issue? It would be interesting to find out. I'd be pretty pissed off to be just beyond my warranty and have an intake gasket failure that could potentially blow then entire engine if gone undetected.

This type of thing is exactly why I got the extended warranty. I bought the car with 24,xxx miles on it and with not knowing how the previous owner treated the car, I'd rather have the peace of mind knowing that anything that will go wrong over the next 5yrs up to 75,000 miles will be covered at no cost to me.

Hi Kyle if you have coolant pooling between injectors 3&5 or 4&6 your lower intake manifold gasket going. The coolant seeps up the shaft of the bolt that is over the coolant cross over ports.
My 96 has been doing this for some time now and tightening the bolts helped a little but no cure.

If you have extended warranty you should be able to get the upper and lower intake manifolds replaced with the new and improved parts.

Lower intake manifold with smaller EGR pipe- 24508923.
Lower intake gasket set- 12537197.
Upper intake manifold- 17113136.

Well, thanks for the p/n'*, but they really don't help me at all seeing as this is an L67 issue, not an L36 one. I believe this to be just a normal gasket failure. The coolant is not pooling in the injector bungs, but leaking out as shown in the post above.

Finished up this afternoon with the flush/fill.. Runs very smooth...

I'm getting a P0122 CEL... Other references on the forum state that this will go away in a few days because the system is "relearning". Is this true? Is this because of the TB cleanup?

Oh and Kyle. Do you know if the car ever had the coolant TSB performed on it? There was a TSB that basically was a "customer satisfaction" blah blah blah that said they would add some radiator sealer and put thread locker on a few of the fasteners...

Maybe mine had the TSB and yours didn't? Mine last to 89k miles and I'm really shocked that yours is leaking this soon...

Now mine is 2002 and yours a 2000? Are gaskets worn by temperature or time or both?

I'm really surprised yours is failing this soon... Well, on the bright side... You caught it..

Good luck...

2001, but yeah... I do routine checks of all the fluids about twice a month and just noticed that the coolant was alittle low. I made note of it 2 weeks ago to make sure that I paid closer attention this time. Sure enough, there was a leak.

Shawn how did you read the DTC P0122 (TP Sensor Circuit Low Voltage) do you have a scan tool?


Kyle when I look at those pictures all I see is a red and white Chevelle.LOL
