Excellent, thanks Fridge, just what I needed.👍

Ta for the reply Fridge, the other wire from the fan switch goes to earth...... but is sharing the relay earth..... could this be an issue??

Hi All I have a 3.9 efi in a 90. Cooling fan stopped working, was operated by an old kenlow unit which looked to have seen better days. So added one of these https://www.ebay.co.uk/itm/154143713052?fits=Car+Make%3ALand+Rover|Model%3ARange+Rover&hash=item23e3ae671c:g:a-EAAOSw5cNYUqnu But when wiring the relay had a look on t'internet and surprise surprise loads of contradictions! In the end I went with a vague consensus 87 fan 30 power 85 earth 86 therm switch also found 30 and 85 switched around so did likewise. But Fan no worky 😞 Currently have it wired direct and working all the time. I had Rovergauge connected so I had an accurate engine temp so it should have cut in. Here is the install I utilised the existing wiring, hence it's all the same colour! One immediate thought looking at that is I am earthing the thermo switch via the relay earth, I wonder if that's a bad thing? Filter and MAF is all going to change, this is as bought and WIP. But.... mainly.....beyond by waffling.... any one have a definitive working relay connection? I don't need a manual cut out (or in ) just simple on when it gets hot. Ta muchly.

Hi All 12j is now gone, I was going to swop in a 3.5 carb engine from a 110 but an already swopped 3.9 90 cropped up locally. It has been very well done, but there are a few bits I want to sort. No real evidence but apparently the engine has ported heads, tubular manifolds ( def, I can see those ) and an unknow lumpy cam, it ticks over like a dragster so maybe a bit too lumpy! It is quick! But maybe not as smooth as it could be. think more comp safari rather than trials! Anyway, this weekend the boy racer pipe with one silencer is going, to be replaced by standard. I also want to get rid of the K&N, replacing it with a RR air box in the same rough position as a 50th anniversary/NAS 90 I have the airbox, just need to tweak it a little to make it horizontal. But does anyone have pictures of the bracket that bolts to the firewall? I have found one very bad piccy on line but didn't really help. One in position on the bulkhead without the air box on would be great 😃 I don't want much do I! Once these 2 bits are done will see how the smoothness is. Then I need to keep the cooling water inside the engine 😆 This will become a saga! But I still have the rather nice 3.5engine in the garage.................

Ta All Yes Fridge, will deffo try to do the drilling off the vehicle.... ta for the reminder. I do have the inspection cover, should have tried it on too actually...doh! I know the 3.5is a bit old school now and agree on performance. I had a 3.5 90 followed by a lightly tweaked 200 tdi 110, the latter was way more grunty. But I want to keep it all relatively period ( the engine I have is from a same year 110 ) and only need the ooomph for occasional towing. And also want the V8 soundtrack! I do agree that the bigger more modern engines would be a more sensible choice....... but sometimes I don't have my sensible head on 😁

I think I am OK now ta, removed a few studs and it does fit. What threw me totally is the clutch master is on the opposite side to my 90, once I ignored that things went better. I may have to drill and tap a few more holes at the bottom, but will wait until installation time. Pretty sure I have the right bits now which is all I needed the bellhousing for, although it caused me a bit of confusion...... not hard tbh.

Many thanks for taking the time to do that Gazzar, much appreciated. I'll compare the bolt/stud locations later but the layout looks the same as mine as does the RV8LR casting mark. I'm wondering if mine had had a few extra studs added that is causing confusion. If mine is a series one that's good as it should fit the LT77.

Many thanks Gazzar, that would be a great help.

Yes I'm pretty sure it is a Series adaptor as it came with other series bits, but I think that should fit a LT77 As long as it's not for a six cyl series 😞

Ah sorry, left out the vital bit 🤔. The adaptor fits the engine fine but about 50% of the bolts/holes on the adaptor ring do not line up with the bellhousing. Apologies again.

Hi All Finally decided to replace the 2.5 n/a with a Rover V8, just a carb 3.5 nothing dramatic. Gearbox and such are all fine so decided to go the adaptor ring and spigot bush route. I have everything but was keen to test it out before the fitting stage so bought a cheap lt77 200 tdi bellhousing just to test fit. But it doesn't fit, have I got the wrong adaptor ring? It says RV8LR which sounds hopeful or is the bellhousing pointing me in the wrong direction. This is the adaptor ring, bought as part of a load of bits, but seemed to compare well with M&D's This is the bellhousing, from a 200tdi Range Rover apparently, surely this should be roughly the same as my lt77?? Any help much appreciated.

Hi All, thought I would do a quick update. Yes, MOT not an issue...extended...yay! Had the last week off so changed diesel filter...element looked ok but there was a bit of silt in the base so probably worth doing. Maybe a tiny bit better after?? Anyhow...for the time being leaving it as it is...it is the best starting Landy I have ever owned ( that's done it now 🙂 ) and actually gets from place to place OK. I think the main difference between this and my old MOD 110 was the transfer box, being lower closed the gears up a bit. Yesterday it did 3 and a half hours of chain harrowing quite happily and driving home did seem a little more peppy. So will just regularly use it and appreciate it. Many thanks for everyone's helpfull suggestions.

Although I hear we have a 6 month amnesty??

Yup most are still open, just HGV testing stations are closed I think.

Thanks Again all, have ordered a filter, so will fit that, check tank venting and gauzes etc then test. I don't think it has a sedimenter like the 110 but will have a look Ironically was going for MOT on tuesday but the guy I use has had to isolate due to a family member with a temperature, so testing may be a little in the future as it expires in a couple of days! Depending on how that works out may do a little advance.

Yup that's fair tbh, will get a filter ordered.

All the service stuff (apart for fuel filter) was done a couple of weeks ago when I did the head gasket swop, but I am drawn to the electric fuel pump anyway, what circuit would you wire it in to Steve? I am intrigued by fuel cap, have had exactly that on a couple of motorbikes...... but doesn't the Landy have a separate vent ? Although I guess that could be blocked a bit too.... an avenue I hadn't considered.

Thanks All, actually I had been wondering about adding an electric pump, seems to be a popular mod over in the USA, although it could be pasting over another problem i guess. I have checked out all the other stuff, new lift pump etc when I did the rebuild 2 years ago ( and not many miles ) Probably should change the fuel filter actually...may have been some stuff in the tank as it had been sitting for a while before I got it going again, but again not been in there for long. Have checked and def getting full throttle..... almost disappointed it checked out ok as it really felt like that was the problem It has the correct oil, but agree, it is just like it is running with thick tar as a lubricant!!...... I am erring towards fuel feed at the moment. All your suggestions are a great help..... even if it confirms I haven't missed anything obvious... please keep them coming... I am flummoxed!

Hi Gazzar It's just a standard 1.41:1, MOD 110's are a bit lower..... I do have one of those in the garage actually! Injector pump is good, compression seems fine, no smoke when running, bores show hone marks and piston ring gaps were fine 2 years and not many miles ago...plus recon head. The 12j and 19j have a belt, and I changed that when the pump went in, again 2 years and not many miles ago.

Hi All Have a 12j in a 90..... I am realistic...it's slow...but bear with me. I used to have a 12j in an xMod 110, and that was nippier than this one.... admittedly that would have had a lower ratio transfer box. The 90 behaves well, starts first time, no smoke.....now after changing the head gasket... Thought the head gasket may have been the issue...it did need changing....but now seems to have lost more performance! Had the diesel pump reconditioned by Automarine a couple of years back, replaced cam belt and lift pump etc Uses no water and the oils stays pretty clean...for a Landy Diesel ! Performance..... given time it gets up to about 60 on a dual carriageway...happy with that....... but on normal road it can lose speed very quickly on a very slight gradient...seriously hardly noticeable slope...and you rapidly have to drop down through the gears......no real revs....not expecting a screamer but the power seems to be between 800rpm and about 2000 max...then falls flat Throttle stop is ok, can get full throttle and revs fine with no load. It just feels sort of strangled....I know they all do, but this more so. I did a lot of miles in the 110 so know roughly how it should feel. I have 2 thoughts..... or 3 actually! Is the pump a bit retarded?? Retarded ignition gives a bit more bottom end on a petrol...but diesel?? Could the lift pump be not delivering enough diesel?? Or could the injectors need cleaning or replacing...reconditioning. I used the best 4 from a 12j and 19j ( both same part number ) when I first rebuilt the engine a couple of years ago. First one looks a bit sooty but had 2 copper washers ( that was me 😞 ) think the oil on the third one was just from during the strip down....took these pics during the HG change. Any ideas all..... other than put a tdi in...... if it ran like my 110 did I would be entirely happy...doesn't do a lot of miles, minimal towing except a chain harrow and that's in low ratio! Ironically this starts way quicker than the 110 did! that was 10 elephants on the glow plugs and a bit of grinding from the starter...this is 10 elephants and instant start.

OK, all done, had to remove the crank sprocket too. Actually wasn't too bad, lined them up and then shuffled the chain one link at a time to get it spot on.That is with the engine on a stand in the garage...... may be a bit tougher installed!

Happy New year all. I'm having another Doh! moment! Have worked on and owned Landy's for years but at the moment seem to keep needing to shout for help! I am doing a freshen up of a 2.5 petrol engine...... had one years ago in a series and is a particular favourite... will be replacing a 12j in my 90 Was a good runner but the camchain was at it's service limit so today went to do the swop, checked manuals, set timing remove and replace...... but no...not enough slack. Took the original off by removing the cam sprocket, all tensioners and such are removed. Compared chains, both same pitch and number of links, new one very slightly shorter due to lack or wear as expected. But no way can I fit it, tried putting it around the cam sprocket and then bolting it up but there is too little slack to get it square and installed on the cam. I must be missing something blindingly obvious, help please!!

Ta for the reply's all, will check the cylinders, not old but you never know. I thought the springs were correct too, same as series but looking at the WSM made me doubt. Ta Litch but yes I do know it has a transmission brake....... a reminder is always handy tho 🙂

Hi All Have an odd problem with my 1988 90 drum rear brakes. Started really dragging in reverse, tbh thought i needed to do a bit of maintenance on the handbrake but no. Lifted a rear wheel and would happily spin one way but not the other (backwards) So took drum off and had a look, upper spring went from the pin on the backplate to the pin on the shoe by the adjuster. Having a close look at the workshop manual that shows the upper springs join the two shoes so changed it around on both back wheels. Now one of the wheels drags when rotating fowards but is fine in reverse...so reverse of before......ahhhhh. Also seem to have gained a bit of pedal travel but that's the least of my problems at the mo' Any ideas??

It was the earth to the Starter Relay. Odd as it should earth through the loom and it was the only thing not working. But have run a separate earth and all is good now.
