BVSV interchangability?/ Smog

[josh_crosson]

1988 na 7mge automatic california supra

will a BVSV from a 5mge supra or cressida work in a 7mge?
there are two 80 something 5m cressidas at pick n pull and no 7m supras and i need to replace my bvsv valve just wondering if they are interchangable?

Also i failed smog twice now, first time i thought it was because i had degreased my motor and water had gotten in the spark plug valley and i didnt know and tried for about 25 min to get it to turn over causing unburnt fuel to flow through the exhaust, i sucked out the water and got it running again then the next day it failed smog.

the guy said that the cat is bad, but the cat is less than a year old, and the car had passed last year after the install of the new cat.

secont time was about a week later and i had run about a 1/2 tank of 91 octaine and drove it about an hour before the next test, still failed.

so im thinking a bad o2 sensor?

also tonight i got a fault code 71 which says is high EGR temp.

could this also have to do with a bad o2 sensor?

I need to pass smog! any help would be awsome!
thanks Josh
