Bov Modification

[BFHOON]

just wondering where you got the softer spring from as I have put an aftermarket bov on mine and it seems as there isn't enough pressure for the bov to open properly

I used an su carby spring using the tuning kit from my old datto I think it was a number 7.

bunnings have heaps of cheap springs too of all different sizes and tensions.

Sorry to bring up an ancient thread. But in simple to block the bov I get a 1" stopper an put it in the bov hole and bloke the vacuum line with a nail or something? That it?

[Rydeit]

The vacuum line is the one coming out on the right with writing on it yeh? Sorry new to this sh*t

[hawlass]

Yes, sure is. you want it blocked to avoid sucking dust n junk into your engine.

Chair stoppers for the other big hoses and your done.

Thanks hawlass. Do I need two chair stoppers. One for the pipe on the left and the one with the clamp. Or just the one with the clamp

If you want to retain the factory look, you can use 2 X 600ml coke bottle lids. I removed the ridges on the lids ( with a smooth finish, but its not really necessary, so I could get them out of the hosing easier). Put them over both of the crossover outlets and placed hosing back on and clamped where the lids are. Easy, 100% effective and looks just like factory except thr clamps are closer to the end.

Or do it right and remove the bov and install these

Don't the chair stoppers come in a 4 pack lol useful if you have a walking stick to use the spares on ....

I used chair stoppers from bunnings and some hose clamps. 10 min job removing the stock bov.

Excuse the plenum it hasn't been sandblasted yet. Work in progress.
