installed my turbo over the weekend....everything is good EXCEPT.....after boosting and the clutch is enganged it dies......ive tried searching everywhere...i have my crankcase open, im running an audi TT bypass valve...i did have a vac line hooked to it but the car wouldnt stay running so we clamped the line goin to the BOV and everything else is working great...just that dang stalling after boost.

 

wait so your bov isnt getting any vac line to it to open or close?

 

does it pop like a flame and this is a common problem you meetered a bunch of air that you just vented so the motor still dumps the fuel causing a flooding sensation

 

Right there is no vac line runnin to the bov now. It sounds like it is opening though when I let off the gas, I'm tryin an antifouler on my primary 02 tomorrow and a diff bov.

 

ummmmmmmmm you sir fail you need the vacuum line hooked up

 

Yea I know that, if you read right you would see my car wouldn't run with the vac line on. The bov stayed open when the vac line was one, hence is why I'm tryin a new bov tomorrow. My buddy has an hks ssq imma try.

 

yeah most bypass valves wont stay closed cause its meant to be recirced the ssq works fine might have some surge

 

it's opening.....as in fluttering right?

because that's not oepning if it sounds like fluttering

 

What about the whole engine stallin thing? Could it be my bov? Or the crankcase not runnin back into the intake?

 

most likely, what you're describing is very common on closed circuit maf systems

 

So what is everyone doin about it? And do you mean the bov is the prob or the crankcase

 

what are you talking about open crank case????? lol you mean your valve cover breather and yes its most likely the bov

 

bov vta
ahahaha

 

personally i just get used to it. i SHOULD fix it but....i havn't yet.

 

A Bypass Valve should always be recirculated. Especially on a MAF equipped car.

This is your problem.

 

If you put an antifouler on your primary o2 sensor your going to blow your engine up. No ifs ands or buts about it. It will pop, and that will be the end of it.

 

get a real BOV and hook a vac line up.

 

Ok so deff no antifouler lol, got a new bov today as soon as my buddy gets putts church. What about my valve cover vent? Route it back to my intake after my maf or leave it vented open?

 

take a pic cause there are 2 lines the one in the front and the one in the back the one in back needs to be left on or its a huge boost leak and my car had no problems with the staling

 

route it back to the intake dont leave it open.. recircing the BOV though will cure ur stalling problem i believe.. our cars sometimes like to stall after venting to atmosphere.
