    BCM SDD Questions

    Hey All! So, I'm at that point in my infotainment swap where I have to push outside my knowledge zone. Mainly this pertains to the fact that I've tracked my last gremlin to the CJB/BCM differences between the 2012 and 2010 LR4's. Here's my dilemma: I need to swap a 2012/13 CJB/BCM into my...

    Sunroof Drain...or so I thought!

    Hey all! I thought I'd post this as a quick heads up for others out there if you find yourself struggling with water in the footwells and you've cleaned your sunroof drains! Long story even longer, I had cleaned all 4 drain ports and thought I was good to go, but still had water pooling up...

    ZF8HP70 for ZF6HP28 swap?

    I'm toying with the idea of swapping an 8 speed in for my 6 speed, has anyone done this? I can't seem to find anything on it for LR's. It's been done with BMW's many times, but as with everything else, Rovers are a breed unto themselves. The physical swap is easy...easy being a relative...

    Any good aftermarket valve covers?

    Hey All! So, after doing the chains and a whole lot of other items, I noticed my right valve cover is still leaking. Yes, it has both new cover gasket and bolt gaskets, and yes I used the proper sealant on the upper timing covers and where they contact the valve cover. I know for a fact...

    Tricking the air suspension to come on?

    Hey all! Quick question, does anyone know if there’s a way to “trick” the air suspension compressor to come on with out the engine running? The compressor just runs off battery power, so with my voltage stabilizer it should run just fine. (Without the engine of course) Long story even longer...

    Timing Chain tensioning issue

    Hello all! So, I've got another head scratcher. I've just finished my timing chain job, (2010 LR4 5.0) and I've run into an issue with my bank 1 (passenger's side, US model) timing chain. Long story short, I can't seem to get it to keep tension. When I set all my cam variation pre tension...

    2012 RMS audio system output?

    Hey all! Does anyone know the RMS per channel output of the "newer" 2012 1200 Watt system? All I can find in the manual is 12x50watts rms for a total of 600...but that was the "older" 2010-2011 amplifier. I've looked in both the 2010 workshop manual and the 2012+ workshop manual and this is...

    Side View Mirror replacement not auto dipping

    Hello all! So, a month or so ago, I parked on the street and some lovely individual decided my side view mirror was just too nice to leave it on the side of my truck....insert a very disappointed/angry face when I found the carnage the next day. Anyway, I've run into an issue with my...

    Need a scrap AJ133 block, anyone have one?

    Hey all! I'm looking for a scrapped AJ133 block. It can be either NA or SC, either version is fine. I need a prototyping block that's going to get destroyed during the machining process....and I don't want to pay $2K for a good block. So if anyone has a scrap block laying around, I'll gladly...

    NGK vs Bosch Ignition coils

    Out of curiosity, does anyone have any experience running the NGK vs Bosch ignition coils? I run NGK plugs in the engine and prefer them over the Bosch plugs. Recently though, NGK has released coil packs for this engine, and touts them as the absolute best you can buy. That said, aside from...

    To upgrade head bolts or not?

    I'm in the process of rebuilding a 5.0 SC engine and I have a decision to make. As I'm not a machinist by trade I thought I would float this out there to those who have more experience in this area than me. Upon disassembling my engine, I discovered I have the original style M10 size bolts...

    TFT Upgrade

    Hey all! Well, I know several LR4 owners out there have completed this mod, but now I'm attempting it for myself. Everything seems to be going well, except for the fact that I can't find the correct chip to read on the back of the TFT instrument cluster. I've circled the 2 chips I've read in...

    LR 5.0 vs Jag 5.0?

    Does anyone know the difference between the Land Rover 5.0 engine and the Jag 5.0 engine? More specifically, can I use one as a long block for the other? Long story even longer, I need to rebuild the engine in my LR4, and rather than have the car down for several months while waiting on...

    P0171 and P0174 solved....finally!

    Well, I’m sure there are those out there that have already battled this issue, but it took me a while to finally find it! Long story even longer, I’ve been chasing the P0171 and shortly thereafter the P0174 error codes off and on for about 2 years. (Yes, I know that’s a long time, but I had...

    Crossover pipe flange dimensions

    I was hoping someone can help me with a little project I’m working on. Long story short I’m about to pull my engine and rebuild it with an electric water pump and fan set up. However, to minimize down time, I’m trying to buy as many parts ahead of time so when I pull the engine I won’t have to...

    Pistons from ebay?

    Hey Guys! Here’s my dilemma... I’ve found a set of pistons for my 2010 LR4, but they’re from eBay. (Actually I’m looking at a set of 8 for the super charged engine, but that’s a different thread). Typically, ordering stuff off eBay is not a problem, but in this case, I have to wonder a little...

    PWM logic assistance

    Hey guys! I’m hoping someone in the forums understands how the LR ECU handles PWM signals? Long story short, I’m in the process of swapping to an electric water pump and electric cooling fans. The only real problem I haven’t solved (aside from how to route the serpentine) is how to fool the...

    5.0 supercharged into an LR4?

    Hello all! Let me kick this particular conversation off with where I’m at. I’ve got a 2010 LR4 with about 170K miles on it. The engine is slightly overdue for all the timing chain fun, but it’s also developing a coolant issue. Before you ask, the water pump and crossover tube are fine...

    2010 LR4 Multimedia interface update/upgrade?

    Something that’s been bugging me about our LR4 for quite sometime is the fact that all the Bluetooth and cable interface systems have become antiquated....and more importantly they don’t work anymore when trying to connect our iPhones to the vehicle. Typically they just keep cycling and never...

    Finally took the plunge and joined the forum!

    Hello all! Thought I’d take a quick moment to say hi! Long story even longer, I’m the current owner of a 2010 LR4, and have owned it since we bought it brand new. We had 2 different LR3’s before that, but when the 4 came out with the DI engine, we had to upgrade. That said, the rover is...
