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.

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..............

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

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

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

Thanks
