My F/I Forum Thread: https://www.s2ki.com/forums/index.php?showtopic=554309

I was driving home last night, and all of a sudden my Godzilla BOV (which is usually making a lot of noise off throttle) is suddenly quiet...

If you've heard one before, you'd definitely realize when it wasn't working

I felt around the BOV, and there wasn't anything stuck inside it or blocking the sound/air...

Right now, I still feel like the S/C is working fine (feels more powerful than stock atleast), but when I go off-throttle it sounds like a "rubbery" or "turkey-gobble" sound??? (I obviously made that up, haha)

Any ideas on what may have happened?


Anyone have any input on what I should check?

I'm not really an expert on Vacuum lines or BOV's but I'm going to try and figure this out...

I checked my S/C belt, and it is tight.

I am able to spin the Godzilla BOV back and forth, and I'm not sure if it's supposed to be able to move around like that...

I suppose that means that it might not be sealed well on the aftercooler. So that's on theory.

Any help would be greatly appreciated...

Also, I don't have the stock Comptech Air Bypass Valve that connects under the air intake tube-- So I'm not sure if I can connect that open flange to the aftercooler if I take off the Godzilla??

Thanks,
Matt

 

how is your tensioner?

 

spring might be stuck... open it up and clean it

 

I agree if you still feel boost but don't get the rush of sound then it may be partially stiuck open. I agree with taking it apart and clean it. I haven't taken a Godzilla apart but I have done several and they are not hard.

 

It seems as though it's worked it's way loose... A friend thinks that the diaphragm may be shot?

The lazy thing would be to buy a new one $$$, but I'll take it off tomorrow... too cold tonight!

 

After taking apart the BOV, this is what I found...
There is a tear in the gasket (diaphragm?) inside the top hat.





I have attempted to seal the tear using aquaseal (rubber repair glue and sealant used to fix wetsuits, rafts, etc....



Hopefully this will hold until I can replace the gasket.

ha, that should do it... Hopefully you can get just the gasket from the company, goodluck!

 

LOL What ever works huh .

 

My buddys blowoff valve on his turbo hatch just randomly stopped working....wonder if the weather has anything to do with it?!?

 

Only run the patch until you can get a new diaphram. I would want the patch material to end up somewhere it shouldn't.
