There was a thread on the Facebook L322 Group earlier about problems with the 4.4 TDV8 engine, I hadn't heard any of it before but was wondering if others had heard any of it?

Quote:

u know very well y they r better a 3.6 lasts longer than a 4.4 they don't snap cranks or spin big ends or put con rods tho the side like the 4.4

Quote:

The 4.4 is know to spin shells and sieze oil coolers fail crank galleries get blocked and they have poor oil circulation at idle. The 3.6 has 3 failings at higher mileage rockers can fail or become porous, the oil lines can block to turbos but better spec oil and flush can sort that and the passenger side turbo has oil line behind heat shield which causes turbo failure due to carbonising.

Quote:

I spoke to a very good auto Transmissions specialist they said mega flush is not good as it pumps too quickly and creates a lot of heat and can cause internal seal failure, they do a flush that takes a day for the whole process that doesn’t create the heat, but that was far a sport that requires the the gear box lifting for filter replacement and that’s for the same price as a mega flush

Oh dear.

It would be good to put numbers to these claims.
For example, how many of each built, what year and mileage of failed vehicle.

I thought the general consensus was that whilst the 4.4tdv8 has a few issues (leaky o rings, oil cooler gaskets, inlet rubbers, turbo drain mod), there weren't any major failures or huge engine repair bills.

Just how many cases of snapped cranks and spun bearings have there been ? Too many toys, not enough time

Your thoughts are the same as mine, John.

I always thought the 4.4 was pretty reliable. I'm wondering it one guy has experienced something bad. I know the 3.0 V6's have issues and the 3.6's had issues with turbo's and EGR's but I've heard very little about the 4.4.

Sounds like the poster is confusing the 3.0 with the 4.4..... that’s what happens with those engine. Afaik no such issue is present with the 4.4. There is nothing that can't be fixed with a hammer😜😜

Just did a web search.
I can only find links to a couple of TDV6 and a single 5.0SC failure.
This is hardly indicative of the engines in general, and they arent a 4.4  Too many toys, not enough time

My 4.4 tdV8 Fault Log did not find any evidence of engine failures of any kind.
In fact other than annoying failures like rubber inlet hoses and oil cooler rubber gaskets they seem very reliable, especially considering that they are all 7-8 years old and many have covered well over 100k miles.

Only in the last couple of months has one new member started a thread detailing replacing his engine in a car he bought where the engine had already failed.
Maybe he will add to this thread detailing why it failed?

I agree the 4.4 has been confused with the 3.0 that spins the crank bearings!

Interested in the last quote. The oil in these boxes gets pretty hot pretty quick. Unless the mega flush boils the bloody stuff I cannot see how it could damage a box?
I've had all of mine hot flushed, not mega flushed with great results and nil problems. Rehab is for quitters!!!

But it’s on Facebook so it must be true

I must confess to astonishment at the 3L spinning shells. Anyone know if they don't have securing lugs so they are locked when the main & big end cap are torqued down? Blimey, I'm old enough to have scraped white metal off the conrods before separate shell bearings were introduced. There must be an oil issue to heat them up enough to spin? Rehab is for quitters!!!

somebody mentioned this before on the forum, and I'm sure it was facebook info or from a very knowledgeable mechanic

Looks like this member has a tale to tell.....

There’s nothing that seems to energise Land Rover forums more than a potential bad news story about engine reliability

It doesn't seem to me there is a major engine reliability problem with any of the ffrr variants. Certainly, not based upon the low number examples doing the rounds on this forum. On that basis, there doesn't seem to be too much in it between any of the engine variants.

Also, this thread has been posted on the L322 section about the L322 4.4 and it's straying into the L405 3.0 v 4.4 debate?

That might confuse 'the uninitiated'

For the record, our L405 3.0 is very reliable and causes me no concern at all. They're all reliable... until they become unreliable
