Dave,

Here are the VVL (Variable Valve Lift) Solenoids

Once the coolant temperature had reached around 45 degrees Celsius you could drop the revs to idle (around 800rpm) and it would sit there as smooth as silk and the misfire counter on the IID tool wasn't registering any misses at all.

Whatever is causing it only seems to cause it when it is cold.

Dave,

it is cold where I am at but not freezing but here is what I found for my 3.2

Time for the Engine Coolant Temperature to go from 12C to 40C

2 Minutes and 35 Seconds

If you are not even close to this time then change your Thermostat before doing anything else is my advise.


Having said that it is your car and you can do what ever you like


Take care

Paul

Dave,

I also own a Volvo S80 3.2 with essentially the same engine (ok its 225 HP instead of 235 HP and it doesn't have the variable valve lift)

What it does have is a Land Rover Thermostat, because it was cheaper than the Volvo Thermostat.

Note: the Volvo was in the shade so it started at a cooler temperature (less than 50 ft separated the engines and both hadn't run in more than 16 hours)

11C to 40C

2 Minutes and 56 Seconds

Both of my 3.2 have "New-ish" Land Rover Thermostats

In my book that is very consistent.


I like this test it should tell me if my Thermostat is broken.

Thanks for getting me to think about this

Paul

Good info in this thread; I changed my thermostat about 1.5 years ago but now I am going to time how long it takes to get to 40c.

Thanks Paul, the information you’ve posted is superb.

I’ll have a look at it again this week. Did you just allow yours to idle to get up to 40 degrees rather then giving it any revs? I’m a bit cautious of doing that test on ours just now as at idle that’s when the misfire is at its worst.

I’m hoping the PCV will be here early this week so we can get a look at it. Swapping the VVL shouldn’t be too bad to do either so I might try that and see if the misfire moves to another cylinder.

I was just looking through the images you posted, Paul. I’ve noticed something that has caught my eye…

Dave,

The bank 1 and bank 2 is because most engines with 6 or 8 or 10 or 12 cylinders are V or flat.

I personally love the inline 6 but most 6 cylinder cars are V6.

For our purposes Bank 1 is 1, 2, 3. Bank 2 is 4, 5, 6

Just to make things confused the variable valve lift is 1, 2, 4 and 3, 5, 6


Because the code says Bank 2 I would assume that’s 3, 5, 6

The part number you identified varies the intake camshaft so it affects bank 1 and bank 2. (Variable Valve Timing)

The Part number for the variable valve lift is

lr025967


Since you have a code I would replace this part


Switching back to the warm up time

I can measure again just let me know what RPM you use and for how long to get to 40C

If the engine is between 10C and 15C that would be the easiest for me but just let me know what you can do and I will try to duplicate your test

I did my test at idle but higher RPM is fine

Good luck

Paul

I’ve ordered the VVL solenoid today. Land Rover dealer did it for around 60 quid so they’re going to stick it and the PCV in the same box and post it to me when they arrive.

I’m hopeful to see them both before the weekend so we’ll hopefully get some time to tinker with it.

A delivery arrived from Duckworths Land Rover today…



It was 2 degrees at 5pm today so was bitterly cold and my tools were freezing so I only fitted the VVL solenoid. It took 30 seconds to fit which was superb!

I then started the car and it was holding it’s 1300rpm cold start as normal, then when it started to drop off choke and down to idle speed I was nervous… However, I’m pleased to announce that it was idling at 800rpm on all 6 cylinders perfectly. It’s back to being as smooth as silk again!

The new solenoid when giving it a shake you can hear the insides of it moving up and down, the new one was seized solid. I tried poking it with a screw driver but it wasn’t for moving at all. Strange as the car is always serviced annually which is around 6-7k miles on the engine oil.

It was cold and I didn’t have the tightening sequence or torque figures handy to do the PCV valve so that’s tomorrow’s job. Does anyone know the torque value and tightening sequence?

Massive thanks to Paul for the help getting her back to fighting fit. It’s fantastic to hear it purring beautifully on all 6 cylinders again.

Excellent news!

Dave,

You have been upgraded

From..............OWNER

To........CUSTODIAN

I think of myself as a custodian and just to be clear I am never selling my LR2, perhaps someone could buy it from my Great-grandchild long after they have started talking about me in the past tense.

Don't worry about the PCV for now just wait until its above 20C

Here is the link "FOR THAT DAY"

https://www.freel2.com/forum/topic32107.html


And when you get a chance replace the Thermostat and Small hose, bleed hose and intake gaskets as well

https://www.freel2.com/forum/topic32245.html



Now that you've seen that the LR2 is easily fixed by a motivated owner you can never un-see these undeniable facts.

Welcome to the Club..........the next round is on you

Excellent work

Take care

Paul

Thanks Paul,

In the 7.5 years we've had the Freelander this has been the first time it's given us any problems. It's really been a superb car and the i6 engine has been superb.

Makes a change really... we've done an engine swap in our P38, starter motor change on our TDV8 L322, and our Supercharged L322 has been a project for over 12 months now It's had a gearbox, transfer box, prop-shaft, supercharger rebuilt, and now is getting a new rear diff

It's been nice to have the FL2 as it's just worked for 7.5 years!
