How bad is the 5.0?

Asking cuz a TON of these things need a new engine...

Links to Facebook almost never work.

Oh damn, clicking on those doesn't at least take you to the ad?

You shouldn't need an account to look at marketplace ads...

If they are not working...

Those are all lR4s or 5.0 Sports for under $5K all needing a new power plant.

The one for $8K with 200k mi doesn't need an engine, but says the engine was replaced 73k mi ago

Basically....
There is no warning whatsoever before timing chains skip in 5.0 (3.0 is the same, for that matter). It runs beautifully, and then in a split second it's not worth its weight in aluminum.
I caught a cam-related code in our LR4 completely by a chance - while showing the tester to my son-in-law. When I brought the truck into the shop a couple of days later, the liner on one of the tensioners was about to go AWOL.

Some of these engines are cooked - but there's a warning coolant smell before the crossover pipes let go. You just need to be paranoid enough to smell the truck every time it comes to a stop.

They are really worth nothing with a bad engine other than parts. Would be much cheaper to find one still in good shape and preemptively change the timing kit. I’ve heard the replacement parts make it a reliable engine.

That sounds stressful

Ya I wasn't looking to refurb anything.

I just saw these one after another in an LR4 search and was like jeez...

I almost fell for it. There was a fully optioned one owner nice looking LR4 locally with a “blown head gasket”. I think they wanted 4.5k for it. Just under 100,000 miles. I offered them $1,500 for it which is 1100 more than a recycler would give them for it and save them the towing cost lol. Not sure if it ever sold.

The “no warning” timing chain skip goes against everything everyone has ever said about the timing chain. Which is that is clatters for a LONG time before letting go.

I’m also not believe the sudden coolant pipe disaster issue either on later trucks with the updated pipes. I’ve spoken to a couple guys with 2013s who went 150k+ without changing them.

My truck right now is got a whiff of coolant, I can’t seem to get this little brass water pump nipple thing to seal correctly…. The OEM plastic one was leaking but just barely. Maybe a hiss of coolant. Before I replaced that part, I added a quart of coolant in 40k miles.

One of those ads says exactly that!

Chain: I know of two mechanically-inclined and attentive people with well, meticulously, maintained LR4 and RRS, who experienced a timing chain skip - in one case, the engine was done in, and LR4 sold for scrap value. In another, somehow, the engine survived but required about 8k in parts and labor.

Coolant pipe disaster: when I took my LR4 to a shop because of a faint coolant smell, the mechanic pulled both crossover pipes and showed them to me. Plastic became so brittle that the ends of the pipe would crumble in your fingers.

So you go as you go. Our LR4 is no longer trusted to be driven a 100 miles from the nearest Land Rover-proficient shop.
FWIW, when it falls on me to lead a club trip and I know that L319+ vehicles will be present, I ask the owners when/whether this service has been done (besides the usual requirement of a full-size spare).

This has been the experience of those I know with the 5.0 as well. Some still on original chains over 150k miles. They are no 4.4 but think proper oil change intervals and staying on top of the crossover pipes is absolute key

I'm at 124k miles and on original chains as far as I know. I bought this thing with 69k miles and I highly doubt chains were done. I change oil very 5k miles max and not clatter for me. I don't see it as a mandatory preventative maintenance repair. It reminds me of the Porsche M96 and M97 engine IMS bearing issue with failure rates of 8% for the single-row IMS bearing and 1% for the dual-row IMS bearing. I wonder what the true failure rate is for the 5.0 V8?

IIRC, I took the LR4 in for chain tensioners around 155kmi, owned the truck since 17kmi and changed oil at about 5kmi intervals.
I don't think one's got ear good enough to hear chain clatter over high-pressure fuel pumps - their sound is dominant, in and out of the cabin.
Mine didn't make any sound, but it silently popped a cam timing-related code without illuminating CEL.

As far as timing chain failure rate goes, it is 100% for any engine given time; the question is what this time is for an LR4. Of course it is less in general for cold climates and/or heavy urban traffic use; but I also allow for a pretty wide spread of this - it can happen at 100k or not happen in 200k. Anecdotal evidence is meaningless - the stakes in an L319/320/322 are just too high.

All that said, I haven't considered the timing chain issue the main downer about an LR4. It is fickle in so many other respects that it can't be trusted as an overland vehicle.

Unfortunately, I have to agree. Every additional mile I get off road, the more I start to sweat.

 

[MM3846]

I think most of the coolant pipe issues I’ve seen are from out west. Maybe the drier climate rots the plastic sooner.

I've mentioned this in another thread, but an LR4 I looked way up here had the pipes fail at about 10 yrs & 150k

It sounds like an LR4 is like traveling with Princess Vespa.

I assume the 5.0 L322 are the same?

I'm guessing this isn't like the P38s vs Discos where they gave the big boy slightly different and slightly better stuff?

13’+ is supposed to have improved tensioners but understand they can still have issues if improperly maintained
