@@kiekie6470 You’ll definitely want to replace it if you’re getting “Bank 1/Bank 2 running lean” codes. Typically that means that you have a vacuum leak in the emissions system.
Steve Shih Thanks for checking out the video! Yes, I found that when mine failed, I began seeing excess smoke from the exhaust. Most of the time, it did look slightly blue and smelled like burnt oil. Especially on startup.
Is this the same as the crankcase vent valve? Wondering why my trusted mechanic would charge $250 to change this thing. Max $50 part and two hours labor.....?
Yes, it’s the same part, different name. The part itself can be purchased from $30 to $80 depending on the brand and supplier. If you go with something mid-range, you’ll be fine. These are pretty simple parts. If you are even mildly skilled mechanically, you can definitely handle this job. Very easy and you only need basic hand tools. Just throwing that out there. Hope this helps and best of luck!
@@SpikeMotorsports Thanks for the answer. Yeah, I know my way around cars but this Rover is like nothing I have ever dealt with before. Once I got the PCV valve I took a look under the hood to see what I was up against. WOW...it is gonna take every bit of 5 minutes the change it out. I wonder if my mechanic was quoting all the hoses too. (He fixed a different code and quoted me on the other code to fix).
Yessir! thank you for creating this & giving us newer LR owners a nice Lay if the Land. My Supercharged ‘09 RR just threw 3 Codes: 1.) P2601 - Coolant Pump Cont. Circuit 2.) P0171 - Bank 1 -System Too Lean 3.) P0174 - Bank 2 - System Too Lean I ordered a new MAF unit that I will install tomorrow (Wed - 29Jan20) and a PCV valve. I was told that the MAF valve should fix the Too Lean issue, but haven’t looked into the Cool Pump Control Circuit yet Do you have any ideas, recommendations or “Don’t Waste Your Time on That” advice? I live this thing & want to keep it around, instead of returning or “losing” it in a flood or off of a tall mountain bridge.
R. S. The end of your comment made me chuckle. Sorry for the delay getting back to you. The PCV valve and MAF sensor will likely take care of your issue. If it doesn’t, you may have a leak at the connections of the emissions hoses where they connect to the PCV and the intake. I recently had to replace both of my hoses as they were allowing air in and it was contributing to a lean condition on banks 1 & 2. After the replacement, I no longer had that issue. Before purchasing those hoses, have a shop smoke test your system to check for leaks. Those hoses are about $270 for the pair. Smoke testing will tell you exactly where the leak is and can save you some $$$. Hope this helps. Thanks for checking out the video!
Thanks! The parts are the same and the process to replace both of these parts is very similar. The air intake might be on the opposite side of the engine bay, but the procedure is the same. 👍🏻
Hey Mr. Wally, thanks for checking out the video! I have the air intake info recorded but never got around to editing it. Lemme see if I can get that knocked out and posted here soon. I'll post a link for you in this comment thread as soon as I have it up...
Hi! Thanks for video. I have questio, how can we test the PCV, I have read that new PCV you can only blow from one side. Ig air is going throw it means that PCV is broken, the diafragma inside is broken. Is it true? Thanks
I’m curious were you found your short ram air intake? I just purchased an 08 Westminster with the 4.2l supercharged engine and haven’t had any luck finding an intake.
jimmy ramirez Thanks for checking out the video, Jimmy. I don’t believe this would cause the vehicle to blow white smoke. Typically, white smoke is caused by antifreeze leaking into the cylinders and being burnt. The most common cause of antifreeze getting into the cylinders, that I know of, is a bad head gasket.
Hey, thanks for checking out the video. So I've had the same two codes. The cause in my case, and possibly yours is that the PCV valve has an o-ring that has gone bad along with the PCV valve itself. This is often also the case with the hose that connects to the PCV valve and goes to the back of the intake plenum (rear of the motor). I also had to replace that hose because it was beginning to degrade. "PCV Valve Hose" - Land Rover part number 4696662. When these o-rings degrade, it allows air to go into the motor without passing by the mass air-flow censor. The O2 sensor in the exhaust then sees that the motor is running lean (too much air and not enough fuel), and throws the "System too lean - Bank 1" or "Bank 2". (P0171 & P0174) Unfortunately, no one is making an aftermarket PCV hose going from the back of the motor to the PCV valve so they aren't cheap. That said, it may be your issue. The other emission hose is available aftermarket and is a little less expensive. "Breather Tube Hose" - Land Rover part number LR003383 Both hoses probably have the issue, giving you both those code. Here's a link to the Range Rover Forums that has a very detailed write up on these two codes. www.rangerovers.net/threads/good-info-for-p0171-p0174-codes.31898/ It's worth taking the vehicle to a shop capable of leak testing the emissions system to save you from throwing parts at it. Leak testing or "smoke testing the system" is usually not very expensive and just about any shop can do it. They can then tell you exactly where the leak(s) are. I hope this helps get you started in the right direction!
@@SpikeMotorsports I have found my issue! removed the valve cover plastic. Inspected some wires on right side near fuel rail gave them a shake test. There was a black box near fuel pressure sensor when I would move connector truck would stall. i unbplugged and plugged back in this and it has been fine since!
Hi Marcus, The only issue I run into is that it will occasionally throw a lean code for bank one or bank two. I take off the cold air intake in the winter months because it tends to run rough until the engine warms up. With the factory intake installed the winter months, it does fine. The power difference with the cold air intake installed is huge. I also usually gain about 3 to 5 MPG with the cold air intake installed. I keep meaning to get a video up explaining all the components of the intake and where I got them. Just been too busy to get to it. Hopefully soon!
@@marcus328 I decided to replace the PCV valve when I did this service because it had 110,000 miles on it and they do wear out. It was also listed as one of the major causes for throwing the lean codes. The fact that the codes were being activated while the factory intake was installed also helped me rule out the cold air intake tricking the engine's computer. I haven't had the lean codes since I replaced the PCV valve and the MAF.
I purchased the PCV valve through roverparts.com The PCV valve seemed to be the brand-sensitive item. I purchased a cheap replacement initially and ended up with a lot of blow-by which resulted in white smoke from the exhaust. I replaced it with the genuine Land Rover PCV valve and it worked great. The part number is LR003380. The MAF wasn't nearly as brand-sensitive. I think I replaced mine with a Delphi brand MAF if I remember correctly.
@@Demented38 Thays typically done with an OBD II reader if I remember correctly. My issue went away on its own after going for a drive... Maybe that was fluke. Ha
