Has anyone replaced this? Why and any pointers
2016 Z07 120,000 miles
seems like the purge valve is worn out, not sure if there is such a thing on the reservoir but a very small amount of fluid is leaking at the reservoir location with the reservoir at correct level. Started all of the sudden. No engine leaks, KaTech Stage 4 build at 107,000
thanks
Ron, thanks for the reply, great information. I did view the bottom of the reservoir with my Tslong borscope showing possibly a drip mark on the lower section but it’s not wet. I do have a replacement reservoir on the way and it has a new cap (EBay - new)
The cap will relieve excess pressure but where does it actually expell from? The cap itself? If so it would seem the area around the cap would be wet. I have not opened the reservoir since the KaTech build last year and this leak appeared all of the sudden.
Thanks very much!
Yeah, I would expect the cap to vent mainly vapor unless the car is really overheated. There is no hose or anything on the cap so pressure relief drips or stains should start at the filler neck.
i would still do the easy thing first and just change the cap - then see what happens.
