Guys, I am new to this Site. I have a 1991 22RE Toyota truck 4x4 i bought new in 1991. I just changed the motor out to a DOA 150hp engine. My Question is on the 2 VCV's that mount on the top plate of the Valve Cover. One has a Grey fitting the other a Brown. I went to the Toyota Dealer and they cannot find the Grey VCV. Instead it called for the Blue VCV and the Brown. The difference is the Blue VCV takes 3 Lines and the grey one takes 2 with the Blowoff black cover. Anyone know the differnce? Or can i use 2 of the Brown colored ones?
thanks
Patrick

 

The blue is the VSV for the fuel pressure regulator.

The brown (red) VSV is for the PAIR valve.

The grey is for the AC idle up.

Tell him you have AC

 

Whats funny is i gave them the VIN and everything!! I even showed them the part, the could not find the number on it because worn off. So i googled it with the number on it and them still could not pull a part number!! Man, you have helped more than you may know!!! Thanks!!!

 

Many VSV's a being discontinued form Toyota. Two choices...

1. Just by-pass the VSV and run strait off of manifold vacuum. It will just raise your idle like your AC is on all the time.

2. Ebay might have one. I spent months trying to find my specific part number...never could.

I just ended up by-passing and removing all the extra vacuum hoses...


Here is a write up about by-passing the PAIR VSV. The same principle applies to the AC idle up...
