I'm not the ultimate expert on these cars. However, if you have negative pressure (vacuum) under those conditions, I would say that proves the PCV system is functioning. Cam seals, like every other part on the car, have a service life. Eventually, they need to be replaced even if there is no problem...

We have to bi fuel every few weeks.

I'm getting 24/25 mpg. I was getting 26+ before I started improving things.

Ok, I've finally received the parts. Everything fits perfectly. Air duct bolts are 985743, air duct washers are 986500, and front engine mount "flange screw" bolt is 982819. I've decided to not order plastic nuts for wheel well liners. They are a little bit too expensive for a non-critical...

And it was li...
