Thank you for the replies. I’m talking litres not mils 😁 probably 5 litres every 3 months ish (maths give a litre every 400 miles for that) and I only do about 8k a year. There is big plumes of blue smoke on start up and drive away clears up in half a mile. Black smoke on booting it but I feel that there maybe blue in there too! Ive a gut feeling its the turbo bus as its a sod to get to i’ve not gone any further. Cant even check end float unless anyone has a miracle way of doing that?

Engine starts in a blink and ticks over smooth.

I’m on the Facebook group but decided it’s too varied so come back to the good old fashioned bb 😎

Black smoke is a sure sign of over fueling ,    if your engine is still on the original injectors  the injectors at that mileage  will be very worn and are over fueling hence the black smoke , also that the injector washer seals and O ring that stops the oil getting further down the oil gallery will be eroded and the O ring burnt from the blow by , and that oil in the cam shaft area that goes down to the injector top half to cool it down is getting past the O ring and into the engine hence the blue smoke , both your systems go hand in hand , and if this is the case the carbon coming from the combustion will soon block up your oil pickup as it circulates in the engine oil  and very soon starve the engine of oil which will kill your engine , And a sure way of finding this out is drop the engine oil and look up the oil drain plug (some thing that all folk with a 1KD engine should do after every oil change  before putting the sump plug back in after the engine oil has fully drained  ) and check with a torch if the oil pickup which is visible 1 inch away above the drain hole , look to see if the oil pickup strainer is covered in black carbon sludge , because it should be clear and look like a  metal tea strainer or flour strainer , if it is blocked you need to act asap , and same with the injectors if they are badly over fueling you will end up with one or more cracked pistons , you can check if  your injectors are worn with a tech stream system or take it to a diesel injector specialist  or a toyota dealer . sorry to have to tell you this ,

As ever, great advice from Tony. If I could add,  if you can drop the oil and leave overnight, so there are no drips in your eye, or as per Karl use your phone and take a pic up the drain hole, or better still from Karl use an endoscope thingy to look inside. These are great for any other hard to see areas like combustion chambers when injectors are pulled etc or more recently inside chassis members when checking for rust. Perfick !!

It best put new O rings on injectors whenever the injectors are removed just like the injector  seats , the injector seats are actually made of copper with a silver coating on them to make them more durable , but the O rings  should be changed also when removing injectors because the O rings harden with age dealing with such high temps for high miles the O ring will  have hardened with age and with the injector removed then as you reinstall the injector and  push slide the injector back down in the hardened less flexible O ring can slide out of its grove at an angle and not be able to do its job for long and will soon give way , its good practice to use new injector pipes also when fitting new injectors and new injector pipe rubber nozzles (they are the rubber seals that stop oil leaking out at the injector pipe connection at the injector ) due to the risk of dirt contamination into the injectors , its also good practice to fit new fuel return double washer seals ( 5 of them ) at the back of the injectors where the fuel returns back as they are a once use item also . you can get new (not recon ) genuine denso injectors from pfJones.co.uk for about 240 quid each or even less for the older Lc120s 1KD-FTV , First thing I would do right away is drop the oil and look up the oil drain to see if the oil pickup is blocked , hope this helps .

PS also make sure you clean the injector ports to a mirror like Finnish before installing the injectors  so that the injector seat washers make a perfect seal for many miles ,  any dirt even tiny specs in the ports stop the seat washers for seating properly and vastly shortens their sealing performance and erode away much quicker and allow blow by much sooner than they should .

P.F. Jones has had bad reports supplying wrong parts, and poor customer support.
D.I.S. Diesel Injection Services come highly recommended for refurb and new genuine Denso at favourable prices. Well worth comparing.

Thats good to know tractionman , thanks for ypur info😃

[Tractionman]

👍someone known to us had the bad experience Tony, and another had the good. Recommendations are always good to go on.😀

[mawdsk]

Thanks for the replies, much better on here than the facebook group!

I pulled my receipt from Toyota and yes I did do the O rings, basically ordered everything on the Toyota service diagram marked as replace. Didn't replace any fuel pipes though as originally Toyota listed them as replace every time and changed to every so often. Some had been replaced by toyota under an earlier owner. Yes there is data on Toyotas online customer login!

I think I'll get my mate to quote for refurb the injectors, drop the sump, drop the turbo and compression test. Should cover must aspects, then it leaves the valve stems.

Farcebook, who the **** are they ? 🤐  TBH mate, there is, as you've found, no comparison. On here there are a diverse group of people that live and breath landcruisers, sometimes owning more than one or several in a row, servicing and repairing them as neccessary., not anyone's Uncle Sid who had one, or someone who knows someone down the pub who's got one.🤔
When someone comes on and problems arise and are solved, with input from various people and the results shared, its like a big library under one roof. Youve achieved quite a lot there yourself, good luck with injectors etc. 😀😀

Nice feedback Ibex. You can always depend on Tony's advice, he knows these 120'/d4d's inside out, and wont recommend anything he hasn't done himself.
His catch can is o/side corner near brake fluid/brake booster.

Tony keeps giving us a list of jobs, now he needs to send the weather so we can have a crack at them!!!
