from any Jaguar XK engine, whether a 3.4 or a 3.8 liter, there were a number of them, the difference is in the angle of the canister in relation to the "head", and the "heads" themselves were also slightly different, requiring different head-to-block gaskets, otherwise they all do the same thing.
it depends on which Jaguar model it came from, different Jaguars had different clearance issues between the body/chassis and the oil filter assembly, that's why some have different angles, some are straight down, some are 45 degrees, etc., etc.
therefore the different types.
as far as I know, the tachometers have a cylinder head-mounted "dog" which transmits the rpm to the dash gauge, sorry I forget the name of it, Jon help him with this, thanks.
Man I love the accumulated knowledge we have here. It's one hell of a resource! I reckon we could recreate the entire Brown's Lane Complex from the knowledge we have. Maybe we should?
Thanks I did see the different filter types in the book 3 are specified for mk1 but doesn't state which engine had what.
thanks for clearing that up so by my engine picture does it look like the mk1 mechanical rev counter left side back ? as still trying to figure out if mk1 or mk2 head and it just came to me that i thought something had changed between the 2,
haha scatcat i think use could rebuild browns lane so much knowledge here meanwhile i am still learning.
Checked it out, it's called a speedo angle drive, there is a dogged shaft that runs off the inlet cam, which is the rev counter drive shaft, SNG mix up the title speedo and rev counter !
Re The Oil cleaner, the version you have is the later version, fitted to all engine sizes, the early version had the oil pipe that goes to the sump coming from a banjo bolt at the top rather than from a separate outlet.
Ok cool that would possibly be the cleaner from the 58 blocks i do remember reading the early blocks sumps where alloy which had a different cleaner but they changed to steel sumps soon after.
as for that other piece the angel drive thing what model is it from and is it a replacement type for the one i have ?
I take it the mechanical drive mk1 and electric mk2 aren't interchangeable without also swapping gearbox and rev counter tacho ? Which tells me it has to be a mk1 head.. the rego papers to prove the car exists for heritage certificate cannot arrive soon enough.
I do wonder if the car had the modifications from factory would they change the heads prefix to match the block ? Or leave the 3.4 prefix ?
Damian, the picture you posted looks like a S type engine compartment, at least the Air filter "muffler" is definitely S type and it was also used in the 420, (1966-1968), the last of the Small Saloons built by Jaguar before the XJ-6 made its debut in 1968.
Jon,
he was asking about the RPM revolutions, not the Speedo.
Hey jose having a look at s type there muffler is different mine is missing the pipe to wing part this one is my mk1 2.4 with 3.4 top end it has mechanical tacho drive so thinking mk1 3.4 top end, the picture my father sent of the prefix was hard to make out due to paint flaking so couldn't tell if KC or KG but being mechanical and not electric i am swaying towards KC mk1 as unsure if the rev counter drive at back of head can be swapped between the 2
yes I noticed, but the air filter muffler shown in the picture is the same as in the S type and 420, the intake pipe is missing, probably was removed but you can clamp a suitable Hose to the end of the intake side and route it down towards the inner wing.
Actually , the way it is, is probably better, I would add a wire mesh to the intake "mouth" to prevent large insects or any large object from entering the muffler.
They are similar with shape but the intake point is different mine is located at the end while the s type/420 is a pipe that goes down if this is the one you meant ?
