It's been a long while, but I'm hoping someone with more experience can help:
My 1990 Truck has always passed CA smog no problem, but this year my NO numbers are high:
The tech at the Test Only Smog Center also told me the gas fill neck wasn't sealing properly.
My mechanic suspects the fill neck issue is also the root of the high NO measurement.
Here's the issue: The fill neck is discontinued for FJ60/62, so the likelihood is I may be dealing with the same issue from a used part. However, in checking out SOR, it seems like the part of the fill neck that actually has threads for the gas cap is a separate part (which is readily available and only $9):
When I called SOR yesterday, they seemed to confirm that part 3 above is separate.
My mechanic is telling me the SOR diagram is for a BJ or European model and that the US FJ62 is a single piece fill neck.
Any advice/thoughts?
Thanks so much!
