I think i've got a problem somewhere, because my stock BOV (plumb back) sounds like one of those loud aftermarket BOV that are vented into the atmosphere... is there maybe a air leak somewhere?

I supose it sounds cool and all,but its just too lound and brings attention from the wrong people (cops) :)

you must have a pod filter. the air from the stock bov goes back through a pipe and ends up right in front of the air flow meter, making it almost as audible as an atmospheric one. you could always go back to the stock airbox, as this will dampen the sound almost completely.

as for leaks, if you rev the car from the engine bay listen to where the noise is coming from, my guess is the pod.

hope that helps

LOL if you have no filter that's probably what you're hearing.

It's also possible if you're running massive boost that the BOV isn't up to the job of venting the air and you're infact hearing reverb.. but you'd have to be running plenty of boost.

    • I dunno man, that VX S with 200,000 k's is still hanging out for 1.5 I reckon the R34 is the better buy, personally.
    • Dang, doesn't even include on roads.
    • Only in a market where OBD was a thing. The rest of the world was quite happy to let the US EPA only affect US cars for quite a while. The* problem with datalogs is that unless you are very familiar with what every trace should look like, on their own and as an ensemble, you can and will see weird shit that can and will lead you astray, not realising that what you are seeing is the normal consequence of various transient inputs. *Really, "a" problem, as there are of course many other problems too. Look, these cars are so bloody simple that if it is missing or stumbling, the obvious thing is to break out the old mental diagnostic list and just go do all the things that you know you should. After proving that the plugs are clean and sound, ditto the coil stalks, coils, loom connectors, etc, and then making sure that there is fuel pressure at about the right numbers (while driving!, not while sitting in the garage free blipping it), then maybe you go looking at AFM voltages, manually testing the igniter, putting a scope on the CAS, etc. Then you're into pulling the injectors for a spray pattern look-see and perhaps a clean, squirting carby cleaner around the inlet manifold looking for leaks, and all the more annoying and esoteric, but still common as muck faults that these things have. I wouldn't ever bother looking at the trims, as they are usually bullshit on these old clunkers anyway.
