feeler gage setting for landrover 109 petrol model 1981

does anyone know what is the feeler gage setting for the landrover 109 petrol 6 cylinder?

I'd guess about 15 thou, same as a 2.25.

are yu talking plug gap, rocker gap, distributor gap or wot?

plugs usually come pre gapped at about 25 to 30 thou, there's a plate on my engine telling me the tappet clearance is 10 thou so I kind of assumed it was the points gap that was wanted. Do you need this in metric?

Servicing & Technical Information
This is a list of general technical information useful for servicing and tuning your Series 2 or 2A. These figures are largely derived from Land-Rover technical publications and stolen from the series 2 club.

Ignition timing (static for 90-95 octane RON* fuel)

(note RON octane values are higher than the older octane numbers given in LR manuals, 95 RON is about the same as the old 90 octane rating). You therefore may find your 2.25 petrols (8:1 CR) run better nearer to 3 degrees BTDC.)

2 litre

2.25 litre 7:1 CR* * * *

2.6 litre 7.8:1CR* * * 2 deg ATDC
S3 V8 3.5 litre

Timings for poorer quality fuel:-

2.25 litre 7:1 CR
80 to 85 octane = 3 deo BTDC
74 to 76 octane = TDC

2.25 litre 8:1 CR
90 octane = TDC

If your fuel value is not listed, then you can follow the trend and set the static timing accordingly and "tune" to suit local conditions...

Lodge plugs were originally specified by Land Rover for the early models, but they went out of business and stocks have all but run dry, Champion would be the next "nearest" equivalent for later 2s and S3s.


Or any other manufacturers equivalent of these. (Please check with your supplier for suitability in your engine)

All plugs gapped at 0.032" (0.813mm), if using electronic ignition gaps can be opened to 0.038 to 0.042" or as manufacturer advises. V8s at 0.025" (0.635 mm).

Oil filter

2.0 litre Petrol
Element is AC FF24* LR pn: 246262
gasket is 246261
small gasket AC 1530635 and there are 2 of them, 277611
rubber washer for centre bolt, AC 1531098, 269889

2.0 litre Diesel
Element is AC FF50, 248530
gasket for filter AC 1530250, 272839
rubber washer for centre bolt, AC 1531098, 269889
Filter bowl is 1.5 litres capacity, so allow an extra 1 litre of oil, the rest for the filter.

2.25 Petrol & Diesel engines
Early models used a longer filter element - 6 13/16"
original part no: 248863, Unipart no: GFE144 and current LR number RTC3185
original AC number: ACFF50
(you'll note that this is the same as used by the 2.0 litre diesel)

From March 1963, engine number suffix D onwards used a shorter element - 4 5/8"
original part: 541403, Unipart no: GFE130 and current LR number RTC3184
original AC number : AC72

Oil capacity of the sump is 11 pints (6 litres) note you need to add and extra 2 pints for the long filter bowl and 1 pint for the later short filter bowl.
Oil changes (once the engine has been run in) are every 3,000 miles and the filter should be changed every 6,000 miles. If you are operating in arduous conditions replace the oil more frequently. If your vehicle only does a low annual mileage then replace the oil before laying up for the winter.

6 cylinder petrol 12 pints (6.81 litres)
S3 V8 = 9 pints (5.1 litres)

The best grade of oil to use is any good branded multi-grade oil rated at 20W/50.

Differential oil capacity (std. LR 4.7 ratio) 3 pints (imp) or 1.75 litres, front & back, EP90 grade or equivalent.

Radiator/cooling system capacity
2 litre petrol or diesel = 17 pints (9.65 litres)
2.25 litre petrol or diesel = 18 pints (10.23 litres)

You will need to add a litre or so more if you have the optional heater fitted.

Series 2 & 3 2.625 litre (6 pot) = 20 pints (11.36 litres)

Series 3 models (4 pot) with the round top radiator (could be retro-fitted to a Series 2)
Petrol = 8.1 litres
Diesel = 7.8 litres

S3 V8 = 22.5 pints (12.78 litres)

Fan belt size for 2.25 engines is 1050mm circumference. (This number will often be included in the manufacturers ref number.)

Antifreeze mixture ratios

25% mix gives protection down to - 11 deg C
33% mix gives protection down to - 17 deg C
40% mix gives protection down to - 23 deg C
45% mix gives protection down to - 29 deg C
50% mix gives protection down to - 35 deg C

(Note: The coldest ever recorded temp in the UK was -27.2 deg C in Scotland and -26.1 deg C in England.)

The minimum mix should be 33% for peace of mind, unless you live in the North or in the mountainous areas of the UK where 50% is recommended.
We recommend you replace the coolant after 2 winters in the vehicle and that you only use coolant mixture to top-up the rad between times. Only use water for the cooling system in an emergency, replace with correct mix ASAP.
Use this mix the year round as it contains inhibitors to stop rust and scaling and lubricants to protect the water pump and hoses.
Dispose of waste antifreeze/coolant responsibly
