1990 4runner v6 4x4 190kmiles
Just got done replacing the water pump, fan bracket, radiator and belts.
when going to remounnt the power steering pump, I broke off one of the two ports on the air valve to the power steering pump. If I just plugged up the vaccuum line and left it alone what would happen? Where do I get this part? Only parts yard with a 4runner is a million miles away.

 

Better start driving... a million miles is gonna take awhile


Actually, you will probably have all kinds of problems if you don't fix it. If you have a pic would help in seeing if it's fixable (before you drive a million)

 

It is an idle up valve that kicks in for the PS pump at full lock turns. They cost about $100 at the stealership - good luck finding one not already broken at a boneyard. Both of the ports on mine were broken off when I bough my truck - vacuume lines are plugged - Have had no problems at all (after about 15k miles).

 

When I broke mine most of the junk yards wanted me to buy the entire pump. I finally found a yard that let me go find the part and remove it. Cost me 5 bucks. Good luck.
