"the consensus there is that to save the timing chains oil changes with synthetic oil every 5,000 Km and pre-lube or pre-pressurizing the engine before starting will just about guarantee a long engine life without internal problems. The LR3 service interval for oil changes is about 7,500 miles or 12,000 KM which in many mechanic's opinion should be cut in half. I change my oil (Castrol 5W-30 synthetic) and filter every 5,000 Km and use a Moroso accumulator system to pre-pressurize the engine oil pressure for 5 seconds before starting."
This highlights what a poor design this engine is - really for a petrol v6 there should be no need to pre- pressurise the engine and a 12,000km oil and filter change interval is reasonable for a petrol v6 (works for my diesel v6 and it is a dirtier engine).
I appreciate when running the engine is great but but having to do the actions listed in the above post really highlight that this engine has some major design issues.
Now if the accumulator was fitted as part of the engine design that may be different but a 5000km interval for oil and filter when also using full synthetic oil is just not needed on a petrol engine in normal running conditions.

FYI for all... A quick peek at might help educate us all...
However, not everyone is looking for longevity, so we all take our chances regarding engine longevity... 1967 Ford Bronco 289 V8 (1968)

Just found a better explanation from the Moroso Company here

Thanks both, the Moroso explainer was very helpful, I also read up on the Cologne engine in the Explorer forum and now have a better idea of the problem I will likely encounter at some point.
Although I like the idea of fitting Moroso, I am not sure whether I can fit one on mine without impacting my insurance premiums as it may be regarded as a modification. So it appears that a frequent oil change is the best option for me. When I looked at my oil change history, on average I had been replacing the oils at roughly 5,000 - 7,500 km intervals, and max 12 month intervals. Other fluids I have also changed them on time so far, replacing the sealed transmission oil to the ZF provided metal one at around 80k.
If I am aiming for engine longevity, how much of this depends on one’s fitting of a Moroso (or a similar product) as opposed to, well, frequent oil change?

I don't know about the UK, but here and in the USA engine modifications are generally regarded as those increasing horsepower, which might increase premiums, but the accumulator has no effect on my premiums. Engine longevity is tricky, here a driving trip of 500 miles is not extraordinary, but in Europe (except for Russia) is likely not very common at all, so we are comparing apples to oranges. Do some reading and use common sense regarding oil changes, I'm following my own plan for engine longevity, others may have other ideas... 1967 Ford Bronco 289 V8 (1968)

Any modification has to be declared to your insurance company, most will let you get away with up to three mods as long as it doesnt increase bhp or value significantly. I have always informed my insurance and found that they are quite open and honest about there policies.

A quick update during this pandemic (got our Pfizer mRNA shots), the machine has got nearly 50,000 Km on it with the donor Ford Ranger V6 and is quite happy. Just preparing to repair a broken rear passenger door lock and at some point install a manual upper tailgate release cable, while getting the BMW K75 back on the road now that I've repaired my shop infrared heater. There is always something to keep you busy when you retire...  1967 Ford Bronco 289 V8 (1968)

Hi enb54,
I just found your thread after googling "discovery 4.0L v6 engine removal". I believe I have the exact same car as you, albeit a RHD in Australia.
Can I just get you to confirm that you removed the 4.0L v6 engine from a 2007 Discovery 3 without removing the body?
I'm asking because my rear timing chain is rattling and I've just been told by a repair shop that the engine can't be removed from that car and the body has to be removed. Their quote to do this was insane, so I'm contemplating doing it myself, but just want to check what you did.
Thanks,

Hi back Kevin,
yes, we removed the engine WITHOUT removing the body, it is a bit tight but if you are careful you can do it. I have a fairly complete set of general instructions posted on another site that a few others have used to successfully transplant their Land Rover Cologne 4.0L SOHC engines to Ford Cologne 4.0L SOHC engines, plus one fellow in the USA who removed his engine and rebuilt it before we did the transplants. All done by removing the engine from the body, and "5280LRS" mentions the "four part series on replacing the cam chains, guides and tensioners on youtube by fordtechmakuloco" which will be useful for you. Please read the whole thread at https://landroverforums.com/forum/lr3-28/l...it-93456/, and note that "Rocksaw" from Sydney successfully removed his engine and rebuilt it as you are contemplating. My instruction sheet is post #3 at https://landroverforums.com/forum/lr3-28/l...-v6-99856/ . Good luck, you definitely do not need to remove the body for this (Cologne 4.0L SOHC) engine repair job, it has been done many times, even in Australia...
edit: When you do this timing chain job, be ABSOLUTELY certain of how you set up and time the engine while it is out, otherwise you'll be removing the engine and doing it right the 2nd time...

Hi Eric,
Thanks very much for this! Your advice re timing chain replacement is noted  Must admit I'm a little nervous about that, but if I buy the right tools to hold everything in place hopefully it will be okay.
Fortunately my engine is running fine other than the timing chain rattle so I'm not planning on doing anything other than replacing the timing chains, guides and tensioners. In the meantime, the car is not being driven.
Thanks,

Hi back Kevin,
You don't really need those tools if you are really careful, but if you have any doubts then use those tools. Good luck, I think you'll find that the job is easier than some think, also if your starter motor is getting a bit long in the tooth just replace it, it's a real dog to replace with the engine in the vehicle. Any other questions, just post and I'm sure you'll get some help from myself or others...
