Dejon Tool BOV

[95blackGsTurbo]

Anyone used this before? I just looked on thier page and it is he same as the Greddy Type S that was discontinued and is said to hold boost better as well. Anyone using this or am I gonna be the first?

Both me and a friend are using it, only I run more boost. I've had no trouble holding 30psi without any leaking. It's a great mod for street turbos and a inexpensive way to run a bov that recirculates and holds 20+ psi without leaking. Installation is simple too.

It's actually a knock-off that Dejon relabels. The knock-offs are available on ebay for only a few dollars now. One thing that you have to watch for is the diaphragm, which isn't oil resistant, unlike the true Greddy diaphragm, which is. Replacement Greddy diaphragms are available from several vendors for around $70 and will fit in the knock-off with no modification.

If the diaphragm happens to rupture or tear, it is imperative that you replace it.

A search for "Dejon + BOV" produces the following discussion on the topic:

Searching for "Greddy+BOV+knock off" produces a result which includes DiamondStarM's dissection of the knock-off BOV and the first diaphragm transplant that proved it was a viable option for replacement. Excellent reading, I might add.

That is basically the Dodge Garage Mod. I have done that before. Very effective.
