2015 LR4 coolant leak
I just installed the aluminum ones on my L405( 5.0L same as the LR4) they are absolutely a no brainer! The only failure point I can see are the O-rings that they come with and the coolant sensor on the rear cross over pipe. I put a small bead of sealant after each o-ring( so if the O-ring fails... -
LR4 Fuel Issues after alternator fail
Did you find the solution to this. I have a pretty wild fuel issue with my l405( same engine as yours ) and I didn’t think the two were related but I have gone through 2 alternators as well and now have strange fueling issues. First was a reman from the parts store to get us home then after... -

Fuel pressure regulation
Last shop that worked on it said I’d be getting different codes if it was the fuel PCM going bad. Only thing that looks strange to me on live data is the fuel rail pressure sensor voltage. Is always hovering around 0.0097volts vs the low pressure sensor voltage is around 3.57. If I unplug the HP...- Krill

Looks worn in the photo but honestly the top was practically smooth, just reflections make it look indented. Regardless they are now new as well.- Krill

Fuel pressure regulation
I did not look at the chain marks. I removed the # 1 spark plug, rotated engine until it was tdc pulled the crank sensor and stuck the little key lock tool in. Then drained 5 qts of oil. Pulled the vac pump and stuck the timing lock in. FOMOCO legible not upside down. Pulled the HPFPs again...- Krill

Fuel pressure regulation
yes, was hoping that would be off but unfortunately it’s in time. Cam slot lines up with the bolt holes with cylinder 1 locked in TDC. Now getting catalyst system below threshold bank 1 and 2. Assuming it’s a related code due to the fuel pressure codes. I’m officially out of ideas. Not sure what...- Krill

L405 charging fault ONLY WITH A/C off
Problem was indeed the alternator again. Voltage regulator internally failed. When a/c or a big load was on it, it would act like a regular to the sensors so the car would thing there was no charging issue but with no charging load, voltage would be all over the place and it would trip the...- Krill

L405 charging fault ONLY WITH A/C off
Good morning, having a weird issue with my 2014 L405 autobiography 5.0SC back story Alternator shear pulley failed about a month ago leaving me to swap oil alternators in a autozone parking lot. Swapped with now further issues, have driven about 2500 miles since. Finally had time to fix all...- Krill

sucking air between engine and transmission
PROBLEM SLOVED! REAR PCV VALVE I replaced 1 of the 2 PCV valves and the issues continued. The one I replaced looked fine, spring was in order and no ripped rubber gasket so I didn’t bother replacing the 2nd( the one closer to the back of the motor) this morning I saw the second valve sitting on... -
sucking air between engine and transmission
I don’t have the iiD tool but I’ll get one ordered and try it. I’ve driven the car several hundred miles( 100 per day for the past 2 weeks) does it only learn after it’s been reset. Would the reset affect the vacuum issue as well? I’ve been searching for some sort of vent but have come up empty... -

sucking air between engine and transmission
Could it be a damaged intake valve and it’s sucking air through the rings creating suction in the crank case. Don’t even know if that would be possible.( doesn’t seem likely) it’s one of those nights you lay starring at the ceiling running any possible idea through your head and dreaming of... -
sucking air between engine and transmission
One guy at the shop was talking about a “washed out cylinder” from the fuel being compressed past the rings but the owner of the shop said that would be a constant issue not just idling and create pressure in the crank case not suction( accompanied with check engine lights for sure) he said. Not... -
sucking air between engine and transmission
What is excessive suction? I’ll take a video in the morning if me opening the oil cap while it’s running. I agree sealing the hole is a pretty dumb idea....as is spending another 3500 to get a seal replaced:( that’s a good idea trying to get a camera in there to see the seal. As of now there is... -
sucking air between engine and transmission
I have an aviation fuel tank sealer called Pro Seal that would work on it but if its an issue id like to fix it instead of put a bandage on it. just don't understand what is creating such a vacuum. if I open the oil fill cap it sucks a huge gulp of air in and stops sucking from the bottom. is it... -
sucking air between engine and transmission
If I knew it wouldn’t damage anything I’d seal that hole so no water or mud got sucked up while driving -
sucking air between engine and transmission
Yes but vacuum leak through the rear main seal or what? No oil leaks( car sat for 3 weeks while I was on vacation and not a single drip on the floor) could it be something as simple as replacing the Pcv intake valves on the passenger valve cover? -
sucking air between engine and transmission
after having injectors replaced my 2011 LR4 with 195,000 miles is having issues idling with the A/C off. if A/C is on it idles fine. I found that the car is sucking air from that little drain hole/vent between where the engine and transmission meet up. anyone ever had an issue like this or can...
