Rb25 Bov Problems- Can Someone Help!

[EARMUFF]

Hey guys. I just starting having a problem wit my BOV. It's a turbosmart one. The car makes that fluttering sound now. When I rev it under the hood, I can see that it isn't opening. The car is running fine tho. No leaks around it that I can notice. any idea how I can fix this? Do I jus get a new one?

Try adjusting the tension of the spring by turning the body of the valve in the direction of hard or soft, which is written on the valve.

BOV is not designed to open unless there is a presence of surge pressure. Assume there is:

Firstly check and make sure the vacuum source to the BOV is after the throttle body.

If it is, then adjust the valve pressure generally controlled by a spring, like Peter said above.

Occasionally on a brand new BOV the thick oil sprayed onto the valve stiffens causing it to seize, use a wood stick genitally press in the valve and let it bounces back few times till unstuck or spray some WD40.

The tension is backed off all the way. Ive had this one on there for a few years and haven't adjusted it at all. When I took the car out yesterday it was fine, but when I drove home it wasn't working. Ive been told to try pulling it apart and cleaning it. It's a turbosmart dual port one. Anybody had any experience with doin this?

Try the above suggestions first. You say tension is backed off all the way so try putting some tension on, a bit at a time and see what happens.

Is the turbo producing boost?

i had the same issue with my blitz one. You should pull the slide out and run some wet and dry paper around it (1200 grit) then get a socket the same size as the slide and move the slide up and down in the bov. Seemed to take about 10 times for mine to free up. Give it a go.

Sorted guys. Lol I called up turbosmart. They told me how to fix it. I took the bov off and undid the cap all the way till it came off. The spring poped out. I pushed hard on the piston coz it was jammed. Once it popped out you could see along the side of it, the spot where it was seizing. I jus used a bit of kero to clean all the crap off it and re-lubed the piston wit wd40 till it slid freely. Put it all back together and it's fine!!

According to turbosmart you should do this at least every 6 months. They even give you a video. Here's the link if anyone's interested. Cheers guys
