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.

 

Wow.. mine wasn't far from falling off. Thanks for the heads up.

 

just out of curiosity what size vaccum cap did you all use? (dDub) was a big help and said either 3.2mm or 2.8mm, but I don't want ot buy two different caps and see which one fits... thanks

 

I have a question, which I can't answer on my own because I don't currently have my car... That vacuum line--where would it go?

I have a REVi ram air duct, but the stock intake box due to a wreck and the fact that the ram air box runs $140, vs. $258 for the stock mess. I remember that the techs at the body shop said there was a vacuum line that they needed to plug that would have gone to the vacuum actuator on the stock air intake. Now my car threw a P2096, and after a day of troubleshooting and data logging MNAO determined that I'd need a new engine. I don't want to argue with getting a new engine, but after not even 40k miles I just don't see that it would be necessary. So, does anyone know if this vacuum port and the air intake vacuum actuator are related?

I'd certainly like the goodwill created if I fix this "huge" problem with a vacuum plug (they might go ahead and spring for replacing my clutch...)

Yes the line went to the VFAD originally - see page one of this thread for where the plug is .

 

Ever since I installed my Revi I was wondering when or if that cap would fall off or weaken enough due to all the heat in the engine bay. I'm sure everyone of us doing that install thought the same thing...........besides.......where the hell does this actually go!
Mine's only been on less than a year, but you can bet I'm going to check it in the morning. BTW......mine is red and is rubber. Think I might put just a small dab of loctite on it to make sure it doesn't move, but won't jack it up to bad if I ever have to take it off due to cracking or something.

 

silicon would be better..

I bought my intake used and it did not come with this cap nor directions. Anyway I used electrical tape and have not had any issues.

 

lol, that works!

 

Hmmm I better check mine.

 

i have had my revi on longer than just about every one (i know 2 other beta testers that got it on before me) and my cap has never moved. go figure
