i need help with my aps twin vent bov... one of my buddys i work with had a g35 twin turbo and sold it and had this bov on it he gave it to me i put it on my car.. it makes a fluttering sound is it sopost to sound like that???

 

No APS makes a clean "sneeze" sound. It might be too tight. Try loosening the nut.

thats the bov that i have if you could aim me at generals0066 i would appreciate it so you can tell me how to do it

 

After a few months with my new APS twin vent I had similar flutter. I took it apart and the "lubricant" was all gummed up, almost the consistency of soft wax.

I cleaned it all up and lubed it up with silicone grease. That lasted about 2 weeks and apparently all the grease blew out.

I took it all apart again, cleaned it all up and lubed it up with lithium "white" grease. That lasted about 1 week and apparently all the grease blew out.

I asked questions on EvoM to no avail. Then searched around on some other forums. The answer I got was Mobile 1 oil. Now, every weekend when I check the motor oil level, I put a few drops of Mobile 1 in the open port of the APS valve. It has worked fine for the past 8 months.

FWIW, YMMV,...

 

i reallly need help with this do you think maybe you can aim me so its easier to talk


generals0066 thanks

 

i tried loosening the nut but it still flutters a little bit does anyone have a clip or video that you can show me to see how its sopost to sound

 

bump!!! i neeed helpp with thiss

 

it will make a fluttering sound at light boost loads...half throttle.

 

First, you do have it on the right direction, correct? Very easy to put it on backwards. Don't ask how I know. The open port on the valve should point up - assuming normal I/C plumbing.

Mine is adjusted with approx. 1/4" of the threaded adjuster screw sticking out of the end of the valve. That's 1/4" beyond the valve, not the nut. Pretend the nut is not there. It is just to keep the adjuster from moving. After you adjust it. Then put on the lock nut. That said, the adjustment should have very little effect on how the valve works. I don't think it is possible to have it mis-adjusted.

Have you had it apart yet? Is it all clean and lubed up? Do you have a good vacuum source unaffected by other vacuum controlled devices?

At normal boost levels - 18-24 psi or so - normal driving - it should really sound about the same as a normal DV valve. On WOT shifts it will make a brief pffffffffft sound.

At higher boost like 30psi it will make a more pronounced PFFFFFFFFT sound when you shift at WOT. However, it will never sound like a VTA. No one will ever mistake you for an SRT-4. hahaha

Hope that helps.

 

we talking about motor oil? i heard we should use them mobile 1 grease.

 

when i put it on when i look at it should the nut be on top because i put it on sideways

 

Should look like this:

 

What intake is that? That's a big *** filter. Thanks.

 

It's a combination of parts I've bought over the years:
-Dejon Tool Intake Pipe
-AEM MAF Adaptor
-Amsoil EaAU6065 Filter

 

...on your car.

Looks a little different with stock type I/C plumbing.
