Thread: A question on 2 litre engines

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)

Would that be the right engine?

(But shhhh don't tell anyone)

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.
