So after bout a full day of chasing down vacuum leaks from the p/o i am left with just one. the tvsv between the carb and valve cover w/ 3 line hooked to it is cracked at the bottom. i cant find it anywhere online. and the toyota dealer said disscontinued. so my question is where do i come up with one. we dont have any good junkyards or Pick a parts here. the part number i need is 90925-02060. thanks everyone.

btw this is on a 1980 4x pickup w/ 20r.

is this the valve that you are trying to replace

Hopefully it is, and hopefully you're willing to part with it. Because the dealer, strangely enough, was right on this one.

herpestes

don't know if this is the correct valve. there is a aisin 25810-27010
part number on the valve body. let me know if this is the correct one.

Sgt'sYota

it doesnt look exactly the same but real close. on mine instead of the top one pointing up mine points the same direction as the other 2.

My toyota semi-drying liquid gasket 00295-1LG04 no longer available, What do I use on these threads that goes into the water system? Thank you Charles https://www.yotatech.com/forums/imag...es/exp_rig.gif

I would use teflon tape

My First thought was teflon tape , It winds off as it threads, still like the idea, called Edelbrock Gasgacinch Tech line said teflon tape too. I also found Permatex 65 to 300 degrees Thread sealant #80632 with teflon at Auto zone. I called Perma Tex about thread sealant durability, and if can be removed. The Perma Tex tech confirmed that this product is removable, not a cement. It does take 24 hours to set, and the port has to be completely dry. Their site stated, use with temperature sending fittings, hydraulic, air, oil etc. I worked in Aerospace always trying to get best results. Thank you for responding, Charles

If you wrap the tape in a clockwise direction with the threads facing you, the tape will not unwind as you screw it in, it will wrap tighter as it goes in. You have to make sure to wrap the tape in the direction of the threads. I have been a heavy duty truck mechanic for forty years and we use teflon tape on just about any fluid and/or air fitting on the semi's.

Worked in aerospace, can't wrap Teflon tape properly. Sounds like the joint U.S European muck up with metric and standard measurements!

Thank you mwishham for taking your time and responding. I understand the wrap direction, but did not know it wraps tighter as it goes in, not to be concerned about the little bit you see after it is tight. The Toyota factory manual stated thread sealant. This will clear-up any doubt. Thanks, Charles, Happy Four Wheeling!

I realize this an old thread, anybody ever find a tvsv? I need to replace mine, it has the port that sticks up and two horizontal, discontinued part, 90925-02069, any lead or info is appreciated.

I just found out recently that AIRTEX\WELLS is making them now...for the 3VZ-E at least. Which is great...for some of us.

Even though the OEM part, 90925-05047, is still available. And cheaper.

Just found it at toyotaonlineparts.com, they list the 25810-27010 for $67.54 plus shipping I think. toyotapart.com has the photo and it is $75.19, plus shipping.
Got the answer from Amayama parts in Japan and they are discon.
