Drilled 1g bov

[glhs422]

Hey guys,
I just painted this 1g bov and noticed this hole in the top. Is this some kind of drill mod that I'm not aware of to hold more boost?? I tried searching for other mods but didn't find any that described this.

Thanks in advance.

Search for the Dodge Garage mod, but yours doesn't look like that. You drill into the side for that mod I think, not on the top...

Yeah, I'm familiar with the dodge mod, but this isn't it...

Anyone know??

I guarantee that hole will make the bov release during boost. You now have a BIG boost leak consisting of the valve in the bypass valve. . . AND the hole, as the source for the airflow through the hole and the whole top of the valve is from the intake manifold. Who the he!! did that?

Haha unfortunately I bought it that way. I bought a few bov's at the same time and I didn't realize until they were all mixed together, so I don't know who I bought this particular blow off valve from...

Just clean the paint off around that hole, then slap a glob of JBWeld over the hole and call it good.

+1. Glue it. Maybe use a piece of tin over it, or a very small screw with some epoxy.

Yep, the hole itself is a boost leak and will cause the BOV to open under boost, much like connecting your MBC to the BOV line. Furthermore, it's a vacuum leak, introducing unmetered/unfiltered air into the system aside, it can also lead to compressor surge depending on the size of the hole, much like connecting a bleeder type mbc to the BOV line.

somehow I knew that you'd chime in and relate this to a boost controllers feeding from bov lines.

glhs422, if you run a boost leak test, you'll see exactly what he is saying. But, I'd just take his word for it and enjoy my DSM

Hey not everyday you run into a BOV with a hole on top. While we are on the subject, the adjustment rod of an adjustable aftermarket BOVs needs to be tafloned/sealed for the same reason.

Wow, thanks guys!! I really appreciate the help....

Unless you root around in dumpsters for DSM parts. An often-neglected source.
