Hey ya’ll! Slavo from Denver here, new to the forum. I just picked up a ‘10 LR4 HSE Lux (I believe) 5.0 V8 Arctic white with 106k miles on the clock for $2k, but it clearly has its issues.
On the outside it’s in pretty good condition other thank a ding on the rear driver side corner which impacted the bumper a bit (a couple of small cracks that can be plastic welded), the lower tail gate which has a small but relatively easy to fix dent and smashed our tail light which needs to be replaced outright. Everything else appears to still function as it should. The bonus is that the car sits on brand new Bridgestone Blizzaks with fewer than 1k miles on them.
The backstory here is that the previous owner has been plagued with the even side of the engine throwing misfires (not uncommon from what I’ve been reading), this was addressed by replacing spark plugs and all of the injectors on that side. Injectors were replaced on a couple of occasions, the previous owner spent in excess of $7k addressing this with multiple Indy shops in the Denver area, issues which remained unresolved. The car ended up in the hands of the LR dealership for diagnostics. According to LR mechanics, in addition to the injector issues, there may of been an issue with the crossover coolant pipe, which resulted in overheating and a blown head gasket as well as the possibility of stretched timing chains. LR Recommendation is a $23k motor replacement... Yikes!
Previous owner just wanted to get rid of it, I got a sweet deal and the first time I started the car, to see where it was at since I’m already expecting at least a head gasket/timing chain job, at worst a motor replacement, checked fluids, topped off coolant as it was low, I got it to turned over fine and it did eventually start albeit rough followed by a massive plume of white sweet smelling smoke that came billowing out the exhaust - confirms the blown head gasket. However, once the coolant cleared, it’s not sucking in any additional (or not much) coolant and turning over without issue. When the motor is cold, it seems to fire up and runs a bit and doesn’t sound all that bad before cutting out. As it warms up a bit it feels like it’s firing on only half of the cylinders and cuts out faster.
My plan is to pull the spark plugs and injectors on that even bank to see how badly they’re fouled up. Question here is which side of the engine are the even numbered cylinders? The next being is there any other suggestions before I start tearing this motor apart? I plan on investing in an second hand IID tool to help with troubleshooting and overall maintenance.
I’ve read a ton on these motors before posting on here, and can see that if it’s overheated, I’ll likely need to get the head machined, the block re-tapped and sleeved for the head bolts, timing chains/tensioners replaced, get new injectors or have these tested and refurbished, replace the cross pipe, water pump and thermostat while I’m down there.
I’d like to very much fix the car as it’s a dope ride but I’m not opposed to parting it out should this become a full engine replacement.
Any opinions are appreciated!
Thanks so much
