Hi all,   First timer here.  I work on a lot of different cars and these forums are an outstanding tool.   I'm working on a 2007 Lincoln Navigator with  5.4 V8.  126,000 miles.  It's throwing P0171 and P0172 codes, which state lean on both banks.  Some research has shown a faulty PCV valve may be the culprit (also resulting in a P1719 code).     In trying to locate the PCV on this engine, I'm having some difficulty.  Some sources say The PCV valve is located on the right side (2009 and earlier models and 2015 and later models) or the left side (2010 through 2014 models) valve cover.   I don't see anything that resembles a PCV on the right side.  Left side, I see what I think is a PCV, but want to be sure before I do something that damages a component that isn't what I think it is.   The picture of the left valve cover towards the front is what I'm looking at on my Navigator.  Am I correct that this is the PCV?  If so, best way to remove?  If not, where is it?   Thanks for your help!!! Bob

What if said supercar is far more robust than your average supercar, and therefore far less likely to be damaged by going off-road? 

The 300k price tag is something people are pulling out of their ass. Farley didn't say anything about pricing. 

P.S. — No mention on even more affordable model S which will have considerably smaller battery and slightly less powerful motor.  Initial press release said it had a 52 kWh battery and 206 miles of range.  That should reduce MSRP by thousands compared to S+.  

OK, so after listening to Farley's explanation, it makes more sense what they're doing and what they are after.  

Good news for EV buyers, not as great for competing manufacturers.  Not bad for up to 303 miles of range which happens to be cheapest option, the S+.

Buried the lede on bigger issue? 😀   We've all known EVs have high issuance premiums due to higher MSRP and higher repair costs, but the cost for model Y and especially Model 3 seem way out of line compared to Cybertruck.  If correct, and I’m not sure it is, Model 3 owners must be horrible drivers as a group.    

People don't take $300k supercars out when the sun isn't shining.     Nor will they take them offroad.   I was excited about this until I saw the $300k price tag.  

I instead think "why would I want to take my supercar offroad to get damaged".

That's interesting, because having the sex appeal and driving dynamics of a supercar, but having it be something that can handle rough terrain, all sorts of weather, I can definitely see the appeal behind that.
