Awesome work and congratulations Thumbs Up

Thanks, we didn't get any video, but anyone attempting this will have to realize that you basically need to fabricate a drivers side (North America) engine mount, modify the passenger side engine mount, use all the Land Rover engine bolt-ons, and drill and tap a hole in the engine girdle (upper oil pan) to mount the engine oil temperature sensor. There are no other issues for replacing the Land Rover Cologne SOHC 4.0L V6 with a Ford 4x4 Cologne 4.0L SOHC V6 that we could find, and the machine now has nearly 1000 Km of trouble free motoring. Hope our experience helps others who may want to try this...

Fantastic effort! Well done chap.

Although I am curious, if the original engine had a timing gear failure, isn't the engine a non-interference engine? Would it have been possible just to repair the timing 'stuff' and motor on?

Well in this forum, the 6th post on the 4th page explains how all 3 exhaust valves on the left side of the engine (looking from front) were bent when the rear gear/chain assembly slipped, causing the exhaust valves to compete with the pistons for room. I have a photo I posted in another forum, when I get a chance to look, I'll post it here also. The Cologne SOHC 4.0 in my 2007 LR3 was definitely an interference fit engine, and so is the 2008 Ranger engine we replaced it with, Check out the Explorer forum for more tales of timing cassettes for these 4.0 SOHC engines...

Found the photo of the engine block, looks like the intake valves hit also but they are closed, the exhausts were stuck open. Enjoy!

As in Monty Python? I am not sure about the head bolts, but since it is a newer engine I would just get new Ford OEM and replace them. I am giving a hand to a fellow who is rebuilding a 2003 Ford Ranger 4.0 SOHC Cologne V6 and we'll be putting in new head bolts, I sure would not want one to break after going through all the work of rebuilding the engine...

That Monty Python "Black Knight" is a favourite! Costs of the LR3 are now up to nearly $6K, (CDN) and about to jump...

A video of bboldt3's rebuilt Cologne V6 running is at https://www.disco3.co.uk/forum/cranks-no-s...02-45.html on this Disco3 site, my Ranger V6 sounds exactly the same but my engine compartment has the Moroso accumulator mounted on the driver's side...

United Kingdom 2006 Discovery 3 4.0 V6 Petrol SE Auto Java BlackDiscovery 3

I have been rather busy these day to visit this forum or to drive my D3... I just came across this thread and was thrilled to learn that someone here has an intricate knowledge of Cologne V6, as my normal mechanic in the UK, as experienced as he is on all LR / RR models, seems inexperienced dealing with this particular engine.

Mine has done 90,000 km so far, I am no mechanic but have sought to keep this car in good shape. Would you have any recommendations on what to do / look out for so that I can keep driving this car as long as possible?

I think I saw another thread where you had commented about the "harmonic balancer". I don't even know what this is, just learnt that all Ford V6 SOHC will eventually develop a problem but don't know how soon this might happen. Would you think I should be looking out to do a preemptive maintenance on this soon?

Thanks in advance!

Over at the Ford Explorer forum there is quite a bit of information on the 4.0 Litre V6 SOHC (Single Overhead Camshaft) engine but 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. The "harmonic balancer" is located at the front of the engine on the crankshaft and helps dampen engine vibrations. The balancer is basically two steel sleeves with a rubber compound between them, the rubber has a habit of deteriorating and causes the sleeves to separate, causing screeching at startup and eventually serpentine belts slipping off their pulleys.

As far as the rest of the maintenance, change fluids as suggested in the owner's manual (except engine oil, cut interval in half), DO NOT ever spray water around in the engine compartment because Land Rover electrical connectors and water are enemies, and read this and other Land Rover forums. As an additional interesting tidbit, Land Rover originally stated that the transmission (ZF automatic 6 speed) was filled for life, but ZF themselves are now indicating that somewhere around 150,000 Km? (I'm not sure) the transmission fluid should be replaced.

I'm sure others will chime in with more/better information, I'm a pretty new LR3 owner but have owned 4 wheel drive vehicles since 1968, they are definitely more maintenance intensive that regular passenger cars. There are other threads on here that are specifically dedicated to maintenance issues, that is likely where you'll find more information and links to answers.
