Title: Need a Thermal Vacuum Valve ( T V V )
Post by: weitrhino on 12:26:05 PM / 26-Apr-20
In a ham-fisted slip-up I broke a port off my T V V. Anyone have a parts CA20e with good thermal vacuum valve?

I just purchased one from my local dealer ( but the price is high like 43) for the 3 port tvv. This was right before the covid lockdowns in the city. They had 13 in stock at some dealership in upper South Carolina or lower North Carolina.

For some reason no one after market makes the 3 port?

Had a guy hook me up with a used one from a pulled CA20. I'll tell ya though, Nissan made it a big pain in the ass to remove and replace one. First, the fuel rail sticks out just far enough so you cannot freely spin one out of its port. Second, the Throttle Position Sensor is also in the way. The small phillips screws holding the TPS in place are a pain because the one on the bottom is almost impossible to access without completely removing the fuel rail and the #1 injector. I think it took me almost 2.5 hours for this silly thing.
