Hi All,

I am trying to figure out if my BPV is working correctly.

When I start the engine the valve seems to open up about 1/4 off the stop.

Then when I rev the engine it appears to close.

When the engine is off and I push on it with my finger it feels like it is "Springy".

Should it open re than a 1/4"? Maybe it isn't closing all the way?

Thanks,

 

This is a good video on the bpv.

 

The valve should be springy
