A question on 2 litre engines

[Sleepy]

I'm told Olute (1955 107") would have had an "early" 2 litre engine.

Thinking of putting in a bid on this:

LAND ROVER SERIES ONE RUSTY BUT RUNNING - eBay, Passenger Vehicles, Cars, Cars, Bikes, Boats. (end time 12-Jan-09 17:31:57 AEDST) (http://cgi.ebay.com.au/ws/eBayISAPI.dll?ViewItem&item=220338294944&ssPageName=ADME:X:RTQ:AU:1123)

Would that be the right engine?

(But shhhh don't tell anyone;))

Hi,

That series one would have a Early Early 2.0L which is best avoided if possible.

You are looking for a later 2.0L unit. Don't worry there are heaps around im sure one will turn up soon enough.

You will need to get an engine number - the later engines start with a 11.

The earlier engine will have a number starting with a 47.

Elaborate... :)

Thanks Guys,

Obviously I need to learn more about the 2litre donk.

The engine number listed on the ebay 1953 is 26110101.(?)

Not really too fussed as the good ol' 202 is running ok. Would like to eventually fit the original motor so I'm on the lookout for an suitable donk .

My chassis is a 5776**** which is a 55 107" - I had been lead to believe this is the earlier 2 litre, but happy to be corrected.

As alexmassey, and others, have indicated the early 2l is not as good as the latter - but hey I'm a Land Rover owner. ( = masochist;)):D

In a vehicle of this age, there is a very good chance that the engine is not original, so you really need an engine number!

Based on the workshop manual the engine appears to be a 1952 whereas the chassis number appears to be 1953. Which would indicate it's proabably not original.

On a very basic level it comes down to the oil filter. The early 2 litres have a bypass type filter where only a portion of the flow is passed through the filter. The later ones have a full flow filter that is easier to change etc.

Is the engine in the ebay car a 1600????

2.0L Engines

There are 2 types of 2.0L Engine that i know about. I have always only known there to be 2 I think the main reason why everyone gets confused is that the First 2.0L was also fitted to 1954 models. When everyone assumed that the change of model brought the new engine.

The First
2.0L first fitted to the 1952 Model Series One 80"

This engine was used in the 1952 and 1953 model 80" up to the 1954 86" and 107"s.

Engine numbers should be as follows.

2610-XXXX = for 1952 models
3610-XXXX = for 1953 models
4710-XXXX = for 1954 models

This 2.0L did not have full flow oil filtering it had the same system as was on the earlier 1.6L engines which was a bypass system that only filtered a small amount of the engine oil at a time. Also the replacement filter was not a standard cartridge like the later engines you had to get this ZS1 filter and remove the 3-4 bolts holding it on not the quickest oil change but not too bad. Sadly ZS1 filters are few and far between. But you can get a modern spin on filter adapter so you can just use a standard Ryco filter (I have this on the 53)

The First 2.0L's were also known as 'siamese-bore' 2.0L the reason's for the siamese-bore are quite in depth.

The short version is basically when Rover enlarged the engine they left no space for the water passages between the pairs of cylinders. As they were siamesed together. This was perfectly fine for the 4-cyl but was questionable for the 6-cyl versions of the engine as they would get alot hotter.
So the first 2.0L Engines apparently got a reputation for popping head gaskets when not looked after and over stressed...

The Second

The late 2.0L

Fitted to 1955 86",107" up to Early Series 2

The Second 2.0L had what was known as the spread bore design. Rover moved the cylinder bores further apart within the block to have room for water passages between them. This engine also featured a different oil filtering system. In the form of a replaceable cartridge based filter on the drivers side of the engine. There might be more i don't know about this engine so please post.

Engine numbers should be as follows.

5710-XXXX = 1955 models
1706-XXXXX = 1956 models
1117-XXXXX = 1957 models
1118-XXXXX = 1958 models

Now Sleepy i have a 1955 107" chassis number 57751025 it has its original 1955 late 2.0L so if yours is after mine it should also have a later 2.0L unit.

I have stuffed up:o - wrong numbers

1600 engines start with 86, 061 or 161
Early 2 litre start with 261, 361 or 471
Later 2 Litre start with 571 or 170
2 litre diesel - the`third number is a 6 eg 1461020

So the ebay jobby is the right engine.

My reseach indicates the later 2 litre engine was introduced in 1956 - but I am happy to be corrected as my research on series 1s has shown up a lot of conflicting information. So on this basis your 55 107 should have originally had the early 2 litre.

The early 2 litre engine has closer bores so is prone to cracking and in the oil system only part of the oil passes through the filter on each cycle.

On the later the 2 litre the bores are further apart and the oil is sucked from the sump through the filter and then to the engine so all the oil passes through the filter on each cycle - not just a sample like the earlier engine.

Very detailed and comprehensive answers guys, thanks.

Sleepy here we have my 1955 107"

It has it original Late 2.0L as Originally fitted to 1955 Models If you can provide Ol Utes chassis number we can be sure.

James Taylor's Original Series one also quotes

"For 1955, the anomaly was resolved, and Rover switched entirely to spread-bore engines. The 2103cc six-cylinder of the Rover 75 was redeveloped as a spread-bore engine of 2230cc, and the spread-bore 2-litre 60 block was used for the Land-Rover, albeit with a cast iron cylinder head instead of the alloy head used on the saloon engine."

Oh and the anomaly being in 1954 Rover was building two different 2-litre engines. The siamese-bore for the Land Rover and the spread-bore for the Rover 60.

So i am 100% sure that Ol ute should have a Later 2.0L engine.

[Sleepy]

My chassis number is 57761332 .

I've been reading the manual and whilst it isn't all that clear I did find a couple of snippets which would algin with your comments.

Thanks for the pictures.


What's your plans for the 107"? ;)

I've gotta shiny red modern 202 engine. Wanna swap?

Only kidding thanks again for all the info.

The hunt continues..............

[slug_burner]

While on the subject of 2 ltr engines.

Was there any siamese 2 ltr engines with a full flow filter? or did the filter change and the spread bore get introduced at the same time?

Very good question sluggy. As far as i know No as the change to Spread-bore also changed the block to allow the different oil filtering system. Tho going the other way as early as 1950 Rover were experimenting with siamese-bore 2.0Ls.

Ok so if mines 57751025 and yours is 57761332 thats a fair bit after mine so yours is definitely going to have the later 2.0L in it. Which is good because they are easier to come by.

The plans for the 107" one day are to get it running as unrestored as it still has most of its original loom engine axles etc. Just needs some TLC. If you were closer to QLD i might be able to help your with the 2.0L hunt. Problem is Vic is a fair way away.

Thanks again am - Let me know if you do see one - it may be worth the frieght cost!

And I thought it was QLD that was a long way behind.......ummmm......I mean "away".:angel:

Hi Alex
You are on the right track
the later 21/4 was the first with a full flow filter
All 55 107 were fitted with spread bore engines
cheers
Ian

[numpty]

Our 107, Thomas, has the spread bore engine and is a 1955.

[Sleepy]

Can anyone tell me if the 2L ioe was used in any other Rover vehicles - this may widen my search criteria;)

Thanks

http://abcentral.zapto.org/aulro/DSCF2758.JPGI have news for people.
This is a spread bore engine and it has a full flow oil filter. All spread bore engines have full flow oil filters.

Sleepy, yes the 2 litre I.O.E was used in the Rover 60 car although it has a cast aluminium head similar to the 6 cylinder Rover engines. Don't try for the Rover 60 car engines they were as rare as hens teeth in Australia.
