G'day apjmcmahon
Hi Andrew, that looks like a good straight Series 2a, and a Suffix "D" chassis vehicle at that, it would have key/keyless start, cable wipers, flick dash switches and a cranked handbrake lever,
the engine looks to have the earlier Solex Carby on it and the early screw type of distributor leads fixings, the engine bay is very complete and original, and everything is in place
it just needs a wash so you can see everything,( the cheap degreaser from "Supercheap" is brilliant for this), and if you have water restrictions you can use one of those hand spray bottles to do in bit at a time for the detailed work
Those breathers, that you posted pics of, are crankcase and rocker breathers, and as you were advised, wash them in petrol/degreaser/solvent to clean them, do NOT oil them,as they are for letting the fumes out, not in, as they will oil up quite well in 10,000miles
The rocker gear tells me that you have a sump full of oil/water mix, probably from the head gasket that is blown across a water jacket, remove the head, and have it surface checked for warping and cracks, you will also need to replace the "Core Plugs" they are the aluminium plugs in the top and rear of the head, as they corrode away and you will lose the water and possibly cook the motor, (I know as that happened to me just on a year ago
) these are threaded plugs and are readily available, I have the part nunbers for them somewhere,you will need a VRSH gasket set, (Valve Regrind Setwith Head Gasket)(about $55 from the Mob in Melbourne) that wil contain roughly the following, head gasket, rockercover gasket, manifold gasket, thermostat housing gaskets, (good idea to replace thermostat 72deg,$18/20) also replace the little straight bypass hose (Head to Block $5-6) and while you have the head off replace the welsch plugs (with Brass ones) 3 down the left side of the block under the manifold while the manifold is off,
If there is light rusting on the bore (no pitting) a light rub over with 380 wet/dry sandpaper should remove it, that should get you a functional motor to keep you going
Tune up data for the 2.25 litre 7:1 compression Landrover motor is:
Tappets: 0.10 thou inch-- hot or cold
Points gap 0.014-0.016 thou inch
Timing 90 octaine petrol: 6 degress Before Top Dead Centre (BTDC) Vaccuum disconnected
Timing mark on "K" suffix Motors front of engine left side adjacent to pulley,from vertical - 6*
-3*
-TDC
Hope that is of help for you, I have rebuilt several of these motors and have both the workshop manuals and the master parts books
if you have any problems PM me
cheers
