Trying to get a land rover started....the sound track of my youth. My dad and grandad would do the same check list every weekend.....then the eureka moment. ....then off for a jaunt somewhere, only to be repeated the next weekend. This was our family entertainment.....thanks for jump starting an old memory.

[@williamgeldeard9589]

Mike it is idling a little slow. Give it an oil & filters change and take her for a blast!!

[@andicog]

Great video, I had the same in mine, how the British army specified that engine in a relatively new vehicle is beyond me. Mine was smokey, ran it for ages but turned out to have a bent rod and hence low compression on one cylinder. Had it rebuilt, Inc injection pump, ran beautifully but was still all done at 60mph, throw in a hill and it was done for. 0-60mph was in hours. Think N/A stood for 'Normally Asthmatic' or 'Not Arsed'

[@BritannicaRestorations]

I was told there was some NATO requirements for engines to withstand EMP - electro magnetic pulse in the event of a nuke going off= at least it would run

[@andicog]

@@BritannicaRestorations Tdi would be the same, no electronics to wipe out, the EMP wipes out semiconductors, good old tdi will still go once the bomb drops, at least I can still get to Tesco after armagedon. 😁

2hrs labour or $$$$ for new injectors glow plugs and maybe ok nah two hours of Doc Brittanica sound best medicine to me

[@paulmartin6397]

Memories of my very first Landy, a n/a 90. Years spent fettling that engine and this video brought back the fun I had trying to get the air out of the system after I'd replaced the head gasket (again). And the clatter of the engine at idle - suddenly I was parked up on a Welsh mountain road again!

I have been thinking that the old diesels all need glowplugs working, Winter or plus 30 still need a glow LOL, My series is just like my old English tractor, No glow No go :)

[@PillSharks]

Best sounding Land Rover engine ever in my opinion! Strange to see one with a viscous fan fitted? They normally had fixed fans! Them old engines needed plenty of heat even in the summer and as much as I loved them they were underpowered, I’ve still got our first genuine county with the 12j fitted, I laid it up in 1999 and had a go at starting it around 2012 and she fired straight up! I bet a good service and a long run will sort that old engine out Mike, good luck!

[@BritannicaRestorations]

A viscous fan floating in the middle of nowhere is totally useless Not only is it not drawing air through the rad at idle, the lock up bi metallic coil will not work

[@jameswright3798]

Viscous fan was fitted from 1987 onwards to both the na and td until the tdi200 took over in 1990

[@davehaining9830]

Good one Mike, having the 2.5td 19j fitted in my old landy and isn't a hundred miles away from the 2.5 n/a, this is all good hands on interesting stuff, it's much appreciated the time you take to do these videos and knowledge you pass on - Dave

Tad moist today and I have a Nissan coming in for some work = let's see what the afternoon brings There has been some work done on the valve cover - I wonder if a valve has been over tightened? How exciting!

[@peterpeterson9903]

Mike... I noted the throttle linkage moving while starting. I had (still have on a pallet) a 2.5NA. Great engine but a bit of a pig for air issues and cold starting. I got a copy of the Lucas CAV manual and was struck by some words, 'Do not actuate throttle during starting' the reason then given was that the CAV would go into maximum fuel mode when then engine speed was less than a few 100 rpm. When the governor was at such low speeds it went into cold start mode automatically. Moving the throttle linkage, at all, would disable cold start. I now have a 300, Bosch VE's, as you know, deck it for super duper cold start. I suspect your Bosch starting habits kicked in here.

[@Br1anuk]

That sound of the engine turning over takes me right back to my 1988 British Leyland FX4 Taxi fitted with the same engine. What a load of s***e. I believe they don’t even make good boat anchors.

[@SeriousSchitt]

Mike, Land Rover Sophie recommended me to come here on the basis that you're incredibly clued up on Land Rovers. I'm wanting to do a coil conversion to my SWB Series 3 Land Rover using a Discovery 1 chassis. I've heard that I'd need to replace the outriggers (front and rear) shorten the chassis slightly and cut and weld in a Series cross member for the rear. Are there any other pitfalls I will face with conversion, such as hooking up the power steering, or any other thing that may be an issue? Has this conversion ever been done before? Thanks from New Zealand.

[@BritannicaRestorations]

It has been done in the past - I have not done one, but I know there is an issue with the fuel tank location and the radius arms. On the 90 the tank was shaped to compensate for this so they could use the same seat base (90/88) This is a huge can of worms - remember the coil sprung axles are wider than a series, so you will have to fit the plastic eyebrows - like the Defender Steering - you will probably have to use a Defender steering column and parts to hook to the power steering box Designa chassis in the UK do a coil sprung chassis for an 88, but their website is shite! designa-chassis.co.uk/88coil.html It is a lot of work - are you doing this as you want a better ride? If so fit a good set of parabolics on!

[@SeriousSchitt]

@@BritannicaRestorations Hi Mike, Thanks for your help. Yes, it is for a better ride. Not too worried about fuel tank or ‘eye brows’, things like steering linkages are more of a concern, outrigger placement, rear cross member attachment and shortening the chassis accordingly (stuff I mentioned before) but yeah, nothing’s easy. Picked up a Disco 1 pretty cheaply and got plenty of time.

[@icstreeservices9820]

Didn’t realise they were still around mike, I had a 2.5na in the early 90s bomb proof but my god so slow and noooo power!

[@mrcvry]

Diesel is a bit powerless but I have no problem with the 2.25 petrol. In the city and around it is as fast as all the other cars.

[@BritannicaRestorations]

In fact they were bomb proof! If a nuke went off they would not suffer from electro magnetic pulse, knocking out electronics There was method in their madness!

[@dietmarw]

Having owned a 19J they really need a good glow (least 30 secs) for the cold start. What a difference to the 300tdi that starts without glowing down to -10°C.

[@BritannicaRestorations]

Yes they are totally different for the same engine capacity!

[@dietmarw]

@@BritannicaRestorations I know and can understand your dislike of 300tdi mated to a LT77. But when I swapped my 19J for 300tdi I did not want to install a new gearbox tunnel (something that I would have to source somewhere again) plus I like the gear pattern better and the LT77 in the car was already rebuild by Ashcroft 10 tkm before. I now love the space in front that makes a timingbelt swap sooo much easier. I do have a electric fan but the cooling is so good that it almost never needs to come on. Well not here in Norway anyway.

[@BritannicaRestorations]

I used to take the fans off 300 Tdi in winter as they were a waste of time in Canada -but essential in summer when you are in traffic!

[@dietmarw]

@@BritannicaRestorations What is this "traffic" thing you keep mentioning? ;-)

[@leeaitken2592]

​@dietmarw is there a reason not to mate the 300tdi to a lt77?? I'm thinking about doing that conversion to my 1984 2.5 na csw

[@jameswelham7041]

Hi Mike, Fascinating video. My 1986 Landy 90 is exactly the same. It's just failed its MOT because it's a bit smokey :-( I'm at the same point of diagnosing mine so am waiting for your next videos with baited breath. I'm told some people advance the pump on these 2.5 N/As in an attempt to get some power (not more power, some power!) and if its over done and to rich they smoke. I'm hoping that's whats wrong with mine. Love your videos and the no-nonsense advice, thank you.

[@BritannicaRestorations]

I managed to squeeze a bit of time onto it today but didn't film it -but I took off the valve cover and the gaps were good and the valves were moving - will have to do a compression test

[@jameswelham7041]

Britannica Restorations Ltd Sounds like a very similar situation. I’ve flushed the oil and given her a good service already. I was hoping some injector treatment and a damn good thrashing would help, it didn’t, well maybe minimally. I’ll persevere and look forward to your next video. Not that I have your knowledge, but if i happen to stumble on the cause I’ll let you know. Greetings from God’s own county by the way!

[@BritannicaRestorations]

This misfire is proving a mystery - I just posted a video on yesterdays findings, but it started to pour down I did a compression test but I am having a hard time trying t find what the figures should be - they are pretty even - within 3%

[@jameswelham7041]

Britannica Restorations Ltd Yes, it seems almost impossible to find the correct compression figures. The Haynes Manual doesn’t say either, just that its important they are even. I’m always cautious about info I find on forums, but I found one thread claiming that the compression on these engines should be 308.7PSI, as its a 21:1 compression ratio on the 12J. The Haynes manual says “If the compression is reading unusually high, the cylinder head, valves and pistons are probably coated with carbon deposits”. I’ve bought a bottle of Liqui Moly Diesel Purge today which was highly recommended by my local motor factors, it says put in the tank as expected OR “Application in case of acute engine problems” put the feed and return pipe directly into the 500ml bottle and run engine at different speeds until just before the bottle is empty. I think I might try something similar at the weekend, only £5 nothing to lose. I’ll keep you posted. Looking forward to your next video.

[@patrickjobling8676]

And double rates mate ..😂🤣😂pip pips and carryon

[@jamesbarker4808]

Couple things from today’s lesson, is the fan set back from the rad like my 300tdi/lt77 conversion and would there be a cowl to fit mine say from the n/a? There is also talk of Batus closing so maybe some wolf 110 kicking around your way unless they all get shipped home.

[@BritannicaRestorations]

Would be better with an electric fan - I think the 300 Tdi fan is too large to fit in the NA cowl

Interesting video Mike especially for us who have 2.5na engine's. I would like to ask you if you can explain benefits of cyclon oil breather as this engine have. Earlier 2.5na 12J engine's don't have them althoug you can see them installed on later military 12J engine's(as this one) as well on 19J and 200tdi engine's. Should I get one? How much will be beneficial or what are a pros and cons of having one?

Mike, I hear that is ATF but do they have red diesel in Canada? Like our cheap agri fuel?

[@BritannicaRestorations]

You can get agricultural diesel here, but only to farmers - and then you have to have certificates and licences etc. They do not do road side checks here

[@sebtsentsai1157]

Hi Mike, I'm wondering why the engine goes off when you are unscrewing the injector pipe? thanks

[@BritannicaRestorations]

Because you cut off the fuel supply to the injector and if the compression is good, and is is not firing - the will hold back the engine and the RPM will drop - if there is no drop - you have low compression in that cylinder

[@fastinradfordable]

Same theory as pulling spark plug wires making sure all cylinders are contributing equally.
