2011 LR4 Pricing
I believe this is legal, at least in most states. It's also how dealers don't count themselves as an "owner" when claiming 1-owner, 2-owner, etc. But when they drive it for a year or two and sell as 1-owner, that's not cool. (Not that this applies to this particular vehicle.) Yes, an oil... -
2011 LR4 Pricing
Correct, the 2nd owner is the current owner, who is a dealer. The concern is this: "...Fast forward to almost 2.5 years later and the vehicle developed a misfire on cylinder #2. The vehicle had developed a combustion leak, where coolant was leaking into that particular cylinder and the owner... -
2011 LR4 Pricing
So... was the coolant leak into cyl #2 ever fixed? May be worth paying for a PPI at the dealer or indy shop. And hope someone didn't just put a bottle of stop-leak in to dump the truck, and engine problem, on someone else. Also, a second owner calling "quite some time ago" does not align with... -
2013 LR4 - Transmission Sonnax Zip Kit Completed - The Results
Thanks for all this info, and the link to a proper gasket! I've not yet done the conversion to the metal pan with separate filter, and one of the reasons I was reluctant was the crappy paper gasket supplied. I've dealt with those in the past, they are too leak-prone with a stamped-steel item... -
High Output Alternator for LR3
Keep in mind that alternators have TWO ratings. One is peak output at a specified RPM. The other is the output at idle RPM. This will vary somewhat depending on the pulley size. Often, "high output" alternators sacrifice idle output, in exchange for peak output. If you need more current while... -
Help! Its Smoking!
Same here - mine still works fine (so far at 125k), but was leaking substantially at the seam of the outer steel cover. Prior to reading this thread, I didn't know they could fail and suck oil into the engine. Ugh. Had I known this, I probably would have just replaced the stupid thing. :musicus: -
Help! Its Smoking!
Oh yeah, the first time, I spent probably an hour trying to separate the quick connect plastic tube, thinking the red clip had to pry outward. Somehow, I managed not to break it, and eventually figured out you PRESS INWARD on the red thingy, to release the plastic pipe. DUH! everyone else-->... -
TOPIX no longer showing full build ?
It appears that "decoder" just shows generic model info, not VIN-specific data. The VIN above did not show me what color paint, what color interior, options, or anything else I'd want to know when shopping for a truck. (Not a car.) Tried my VIN with the same results. Got a list of colors... -
Help! Its Smoking!
For you folks who have replaced the vacuum pump... did you drain the oil pan first? If no, did any oil leak out? The factory manual is vague and seems to imply the sump should be empty before removing the vacuum pump. But the pump sits high enough that it looks like it would be above the oil... -
Compressor Identification
Thanks for the link! I didn't have version 3 of that TSB. :) There's a date code (2-digit year) cast into the Hitachi cylinder head, shown below. Mine was original from 2010, replacement produced circa 2019. Not sure if the 6-digit number on the end plate is also a date code. Mine was still... -
Compressor Identification
Yup. Best I could tell, there was no significant advantage to the AMK, and the AMK required some re-plumbing (not a big deal, but a nuisance). Sounded like LR switched from Hitachi to AMK due to manufacturing supply constraints during LR4 production? Possibly due to factory shutdown related to a... -
Compressor Identification
There weren't many detailed photos of the Hitachi, so I took some pics of my new one. ~$600 delivered from RM European. The AMK looks completely different. https://www.rmeuropean.com/Products/LR072537-MFG476.aspx Hitachi CMP0001, equivalent to LR # LR072537 or LR023964, metal mounting bracket... -
Engine oil analysis results on 2010 LR4 V8
At some tracks, you are forced to pull through the waterbox (puddle) as there may not be room to drive around it, if you want to keep your tires dry. Mission Raceway in Canada (eh!) is like that. Thankfully, Firebird has plenty of room for street vehicles to drive around the water if desired... -
Engine oil analysis results on 2010 LR4 V8
LOL! Not a chance. The LR4 is too heavy, and has too much grip. The track surface can - at times - literally pull your shoes off your feet, it's so sticky. I'm not even sure if the LR4 can spin all four tires on wet pavement. Hmm, I may have to try that. :D Faster, 2-wheel drive cars often do... -
Engine oil analysis results on 2010 LR4 V8
Our latest (125kmi) UOA is attached. Wear metals still look great, iron is down again, but it was a shorter interval again (4k vs 7k, vs 10k originally). TBN was a little lower than I'd like for a short interval but not of concern unless trying for extended intervals, which I'm not. This was... -
LR4 - LCA - Longevitiy/Diagnostic
I've also had bad experiences with poly on other vehicles. I too would be very, very wary of installing poly on the LR4 if the intended use is primarily on pavement. For off-roading, sure, poly would be great. That said - in general, avoid Meyle like the plague. They are not a highly-regarded... -
Crossover Pipe Bursted on V8
Thanks for posting the part numbers! Just confirming, is that for V8, V6 supercharged, or both engines? -
Air compressor temperature - what is normal?
Got some pics, see below. The "cold start" was with the compressor at room temperature (~35C), also note the motor is relatively cool, but the compressor head temp is high. This photo was seconds before cutoff, which was around 257psi / 125C compressor. The "hot start" was after driving a bit... -
Lr4 5.0 HSE only normal height available
Correct - it could be a leak somewhere, that I'm not finding. This is what I'm trying to figure out. AFAIK there is only one pressure sensor, at the main valve block. I don't think there's any way to test it other than just replacing it and seeing if there is any change. There is no fault code... -
Lr4 5.0 HSE only normal height available
Update on my compressor replacement... while the fault went away, I think the new compressor is just masking the root cause of the problem. But I need data from other vehicles for comparison. More details in a separate thread here... -
Air compressor temperature - what is normal?
For those of you with a GAP IID tool, have you ever watched the live values for the air compressor (gallery pressure, compressor temperature, and motor temperature) as the compressor runs after starting the engine? Or, after lowering to access height and then raising to off-road height? My... -
Lr4 5.0 HSE only normal height available
It's a 2010 LR4. And the pressure is definitely 245-250psi max. Are you sure about the LR4 max pressure being reduced? I've not read that before. The FSM has conflicting info (see below), first it says compressor max pressure is 16.8 bar (244psi) but the reservoir has working pressure above... -
Crossover Pipe Bursted on V8
75k does seem like a reasonable number. I wonder what the "record" lifespans are. Sadly, I have minimal records from the 1 previous owner of my rig. It had the pump replaced under warranty at 50k, and there's a Carfax record which mentions another replacement at ~105k by an indy shop, but I... -
Crossover Pipe Bursted on V8
What's the expected life in years or miles for the water pump, front pipe, and rear pipe? Seems like it might be good preventive maintenance to replace the blasted things every X miles/years, before they fail. :2in1:
