Fitting ReCirc Dump Valve
So been to busy to work on the 2 much recently, anyway I got this dump valve of ebay 't'other day, but I seem to remember people saying there are bits missing.
Could anyone tell me what I need looking at these pics?
Also the valve seems to have 2 inputs for vac hoses as opposed to the one on my SSQV, can anyone tell me where I run the 2nd from?
Thanks!

You need a vtv valve to be fitted in the vac line to the smaller port in the blue vac line you have there

I heard they're £30 from Toyota, that's well over what I paid for the dump valve, which was described as fully working. :( Assuming its not going to work without it then.
So one end of the black vac line to the manifold pressure thingy, the other end to dump valve, and after fitting a vtv inline, the blue hose to the other connection on the dump valve?

I have a receipt for closer to £50 for a vtv.Richpx wrote:I heard they're £30 from Toyota, that's well over what I paid for the dump valve, which was described as fully working. :( Assuming its not going to work without it then.

Doesn't really work without it. Old ones go brittle and snap.
Seems you've got the plumbing idea right

Also when you fit the VTV make sure you fit it the right way round otherwise the bov wont work.
The purple side of the VTV faces the top of the bov, as in this pic -
