For all of you that have the Racing Beat REVi intake, like I do, you might want to read this.

It has come to my attention, that the little red cap, that was supplied with the intake kit, the one that covers the small inlet just under the throttle body, where a vacuum hose was removed for installation of the REVi, can come loose, and fall off. When this happens, the car will start to run lean, and throw a CEL. My service manager gave me a lot of crap about this today. They finally agreed to clear the code, and furnish me with another little cap for that inlet.

All it takes is checking to make sure it is snug, when you check your oil, every other fill up, since you are already under the hood, it is right there.

I spoke with a tech at RB, and he had not heard of this happening until today. But I have had the intake on the car for a long time now, and it could be that the little rubber cap just loosens over time. They found mine, in the engine bay, it looked slightly deformed due to heat, which might have caused it to come off.

SO go check yours, save yourself a trip to the service department, and the hassle of explaining that the intake is not killing the car.

I figured someone must have had a problem with that by now. It took me and my brother a good ten times to get the dang thing on when we were installing it.

forget getting it on, taking that vaccuum hose off was a P.I.T.A.!!

L8apex, thanks for the heads up on this. I'll make sure to check it when I check my oil every week.

Anybody have a good picture? I remember putting it on but with old age can't remember where and I cant find my directions.

Now I am getting the LEAN CEL, saw this post and said great!, but I cannot see where it should be. Is is under the accordion section of the OEM intake, after the MAF?

TIA

Wow, just checked mine, and I pushed it back up about 1/8th of an inch. Thanks

Sure enough. Mine is gone. Mechanics probably knocked it off while changing my plugs and wires last week.

Tygon tubing and a golf tee will have to work until I can get them to find a more suitable plug.

just get a regular rubber vacuum cap at any auto parts store, they generally will not fall off

i have taken care of the problem with a piece of rubber vaccum line hose, and a nice polished screw in the end of the vaccum line. it seems to work, and is not too noticable when the hood is up.

I put my cap on with a dab of silicone...hasn't moved yet

Great catch! I just checked mine and it was almost off. I wonder if that is why I get a CEL occasionally.

Well thanks for the reminder, but mine was so hard to put on, I highly doubt it will come off.

However, I was suprised it was a hard plastic. Hard plastic doesnot like heat over the long run.

I've never seen a rubber cap go bad except over 100,000 miles and more than ten years of use. Even then it's not that common.

use a small cable tie to make sure it will not fall off again.

mine was very hard to put on too, I had to use the flat side of a pliers to push it on, and it still managed to come off over time. It is a hard plastic, and it was melted. I am sure that is why it came off. But hey, it never hurts to check.

This wouldn't just be for a REVi system, it'd be for any intake that removes that line.

Anyways, I prefer silicone caps over rubber ones. From my experience the rubber ones deform and crack/fall off way too easily. The silicone ones I've never had an issue with. They fit a lot snugger (when using the proper size of course) and don't seem to move at all. I cannot count the times I've had a rubber one start to deform and crack over time because it's a POS.
