Intake leaking

[kehecross]

She sucking air on the driver side right in the middle of the manifold.(sprayed it with MAF cleaner right at the spot where it sounded the worse and it stalled out.) Anybody done one of these? It doesn't look too hard at all. Any advice?

You have CEL code 172 etc. It's very common problem with the 6VE1 engine. No big deal to fix. Get new plenum gaskets and go to work removing the plenum. When you replace be careful not to over Torque the bolts. Hand tighten to 13lbs max. That's all. You'll be back in business in no time (allow 4 hours for labor).

I assume you mean 13inch lbs correct? I am in the process of looking that info up now. And yes I did have the CEL codes 171-172 She is running pretty bad. I have been noticing that my gas milage has been getting worse for about the last month from 14 to 15 mpg's to 10-11mpg's and then one day I started it up and it went to 2000 rpm's and then back down and was running real rough. Thats when the light came on.

I just found it in the shop manual it is 18 ft lbs

If I recall correctly, there was a TSB that changed it to 13 because 18 proved to be too much.

Uh ok! Hey I just got back from Vegas. I was out there from wed to wed. We had a great time. The weather is much better out there then here.

When i replaced mine it was a HUGE PAIN! Nothing went right! I had to end up cutting the EGR tube since the collet nut was frozen to the manifold. Luckly my brother was able to weld the tube back in one piece apparently the dealership wanted over a $100 for a new tube! Once I got to the gasket to my shock it was cracked and leaking into all the left bank cylinders! Remember to torque the manifold back down to 13ft. lbs. not the suggested 18 ft lbs that the manual specs unless you want to do the job again. I know i sure dont!

It went really smooth for me, Everything came apart like new. Pretty lucky I guess. Going to put it back together Saturday we have to see how that goes. Hope I didn't use up all my luck. lol The new gaskets are a lot different then the stock. I don"t see any plastic in them.

Well she is all back together without a hitch! And she is running way way better. I just wonder how long it was leaking without throwing a code? I mean could it have been leaking just enough that the computer was ajusting things to makeup for the extra air before it got to bad. It has got a heck of a lot more pep then it had before. I know my gas milage has been suffering, But I thought maybe it was the winter blend gas. All I know is it just runs so much better.
