I think this has been mentioned before but I'm not going to go looking for it.

I removed my manifold and was cleaning it, submerging it in water/degreaser. When I pulled it out I noticed a little stream of water coming out the passenger side of the manifold where the shaft for the runners sits. I shook the manifold a bit and the stream of water would stop and start.

Now I didn't look any further because I'm no longer using that manifold but, seems to me it could be a problem for anyone in stock form or boosting on the SVT manifold.
Maybe a dab of RTV would fix the problem. I can't say for sure. Just letting you know.


Passenger side of the IM. It's hiding just behind the alternator, slightly above.

Yup its only a matter of time dang plastic. I don't have to worry my jrsc is all aluminum. But when I was n/a or for my 2nd turbo car I would highly suggest getting a custom intake manifold fabbed up.

You're talking about the runners for the high rpm stage, correct?

If you (or anyone else) could post a photo of that leak area it would be MUCH appreciated. I'm chasing a vacuum leak that's driving me crazy. It's also time to clean the intake - 70K miles and never been off so no doubt I'll find it but knowing where I'm supposed to look helps a LOT when time is an issue.

Thank you - much appreciated.

Would this help cause a big decrease in mpg?

Would this help cause a big decrease in mpg?

Generally yes. The ECU will compensate for the extra air by adding more fuel until the mixture is correct.

Guess Imma have to take this off and check it when I take the exhaust manifold off for re-wrapping. Ugh

 

[iminhell]

I doubt it. I was still pulling ~28mpg with the leak.
Like I said, it is small and for the most part you'd never know.

A big drop I'd look elsewhere, O2 sensor, MAF, TPS, plugs/wires, etc.

i dont see anything wrong in that pic unless its that round hole maybe i didnt understand where to look does that shaft sit on the other side?

 

[iminhell]

The shaft sits on both sides. The shaft is just like that of a throttle body.
Yes, the little hole.
