- The smoke is getting out of hand. Why do you think it's smoking like this? We'd love to hear your suggestions. The Toyota LandCruiser 100 series came with a 4.2 litre turbo diesel called the 1HD-FTE. They're known to be reliable, but this one is experiencing some sadness. Could it be the fuel injection pump? What do you think?
Stack Pipe, fuel pickup, tank filters and genuine fuel filter. That was similar issue on a friends and that is how we fixed it. Its common to think that tis dead but its just all gunked up filters and the stack pipe (if it has one) if not, i'd suggest injector failure and its intermittent. It may also explain the noise, the pump is working harder cus its not getting the fuel it needs. Good luck guys.
worn valve stem seals cause smoke on start up as oil drips into cylinders making heavy oil fuel mix in combustion chambers..easy fix time consuming, but easy to replace said seals..low pressure to injector pump can also cause rattle in injector pump..i would eliminate all of these before replacing very costly injector pump...i hope this helps in some way..
White is usually indicative of overfueling as diesel causes a white mist when atomised and unburt. Partly burnt diesels usually black and oil is blue.
Fuel pumps like that without looking it up might be part of the timing and it controls when the injectors fire before the days of common rail.
They also run on a cam system inside the pump and the lines feed the injectors remotely. Due to this the rattle could be normal coming from the pump. As advised in other comments reduce the amount of work it has to do by changing filters etc and see if any change.
Im no expert so just my thoughts.
Reason it smokes: It's seen things...
gasket? check coolant res to see if its got bubbles when engine is running
Hi, first of all, love the channel. I have the same model LC new since 2005, only 140k on the clock, serviced regularly and only motorway and city driving.I have the same issue as you plus It is burning a lot of Oil.Heavily smoking on some start ups as well, blue/white and sometimes black. I have taken it to a few mechanics and their opinions on the issue are different. I had the injectors cleaned but still have the same issues. I am hoping I will finally find out the issue from your video lol
Well so far nothing cheap has fixed it. We've got a few more things to do, but all signs point to the injection pump right now. We've got more videos coming as we try things out.
How is the hose of the turbo going to air cleaner? Filled with oil or not? If filled with oil,piston rings might be worn out.but still,it's cheaper to have the injection pump be overhauled or replaced whichever is cheaper. In the Phil's, overhauling costs $300
I would say it is normal. Old diesel engines with mechanical injection smoke when doing cold starts. Cold weather more smoke. Solution is to install a block or pan heater.
do you know how low was the compression on each cylinder when you did the compression test pls ?
Going through a very similar issue with my hdj100, on reving it to 1500-1700rpm it will blow a fair bit of white smoke, and shakes its ass off. I've tried a known working ecu and spill control driver, aswell as running and earth from the spill control driver directly to the battery as that can be a common issue (earth's through the mounting bracket)
Have put a new plug and checked wiring to the timing control valve another common issue.
A diesel tech here in Australia said they had one with the same symptoms before chrissy and changed injectors and pump with no success, refuned old mate his pump and then went hunting around the wiring. Found dodgy/aged wiring to the crank angle sensor and that fixed it. However they did that to mine and still no luck. I checked through it today and noticed exposed wiring at the plugs, next step I'll replace the plug then the sensor itself, then I guess I'll have to get injectors tested and then pumped tested.
We tow a 3t van and seems to still pull alright but does use more fuel than it should and while accelerating it makes an annoying rattle noise
Seems like the timing is out
Did you get a good result after fixing the crank angle wiring?
Unfortunately haven't gotten around to it yet
Injectors I had a pd130 running rough as balls white smoke for abit and replaced injector loom which stopped it running rough but once it sat for abit one of the injectors leaked which caused it to smoke but that's just my experience
I'd love to be able to tell which cylinder is causing the smoke, but the electronic diagnostics just aren't good enough on this old bus 😔
Check the tappet valve clearance if it is right then go for fuel pump and injectors
Checked all those and turns out we had 4 damaged pistons, ruined bearings and a blown head gasket.
I had a similar issue on a bmw turned out to be a bad glow plug relay thats caused smoke
Another great idea - this particular engine doesn't have glow plugs, but it does have an intake heater screen to do a similar job. That's been tested now. It draws 100 amps at startup, so it's clearly working!
I have a HDJ79 that is also smoking. Starts mint and runs perfect, just has some grey/white smoke coming out the exhaust. almost hard to see when idling and easy to see when you give it a rev. Doesn't go away when warm, any ideas? Been sitting 3 years hasn't had a good run since (broken diff) so hoping it just needs a good run. Didn't do it before sitting 3 years from what I remember.
If anyone is wondering - a good drive on the highway for an hour cleared it up.
I would look at the injector patterns first, then servicing the pump after that. Worth doing both once above 250k, haven't seen many 1hd-fte engines failing.
A good place to start. We removed all the injectors and got them serviced and ultrasonically cleaned (some were absolutely filthy). I think it's going to be that pump. I wonder if I can find a place to service it rather than a complete replacement.

inital startup points to leaky injectors or pump .... is it using oil or water?
So if you gun the motor the smoke amount should become less dense .. But if remains the same color when you increase RPM I would do a leak down test to see if the cylinder pressures are within spec .. If they aren't maybe you have a head gasket issue , or an issue with the rings or cylinder walls ? ..
You are right! Head gasket was gone, and 4 of the piston rings were ruined and crumbling.
Hi there, my 4.2 fte cruiser did exactly the same, I spent months looking into it, if I was you try wiggling the wiring to the fuel solenoid on the pump, mine was exactly the same, the wiring from factory is too tight and pulls on the pins happens at around 200k, uk cars seem to suffer.
I strongly advise you check that wiring and connection, as mine was exactly the same.
Have you done a test on the plugs? If its only doing it from cold then clearing out its where I'd start. I could be completely wrong but worth a try
Sadly no plugs on this model. It has a glow screen which is working perfectly. So far all signs point to a knackered engine
Blue smoke indicates some leaking piston/s probably some rings.
You sir are correct. This engine needs 3 new pistons and rings
@@vPerformance ouch, not cheap going by my own experience. I opted for a full rebuild.
Exactly bad piston rings sealing
Check injectors and repair faulty
Does the engine warning light have time to come on the intermittent misfires?
No warning lights at all, and no errors stored on the ecu either. Very strange situation
What if turbo seals are going and its sucking oil into the block then when you start it from cold its burning all the residue away
Interesting. I think it'll need a turbo anyway, so perhaps I could get that sorted before spending a fortune on a new injector pump.
@@vPerformance try and find just a replacement core it will be a fraction of the price of a new turbo, easy enough to change over hardest part is removing said turbo
Oh yeah I had a look at the bolts and studs and they're all rusted and siezed. That's not going to be fun to remove.
Either nozzles and fuel pump issue or something major. If I was in your shoes, would start with the basics, replacing engine oil, fuel filter and etc.
Second step would be applying directly Liqui moly diesel purge to the fuel filter/nozzles, sharing link for reference:

Hope it’s not something major. Best Regards from 🇵🇰
Also please consider cleaning your EGR valve!
Bro any contact? In 🇵🇰 suffering from the same or being paranoid help would be immensely appreciated.
finally did you fix???? and watt was the problem?
Head gasket, destroyed piston rings, bottom end bearings, crumbled piston crowns
We change all pistons and rings also injection pump and new injectors problem continue
Water driping to one the piston
Is it because you removed the swirl flaps?
Sadly no, it was smoking before and after.
It's apparent, that you aren't familiar to those engines.
Stick a new genuine fuel filter on, blow air back through the fuel line to clean the tank filter, good to go.
The sound from the pump is normal, just get it out and work.
Keep up on the service and you will only be lifting the bonnet to add washerfluid, this isn't a vag or LR.
The engine has low compression and its being dismantled for new bearings and piston rings. It's ruined.
@@vPerformance How have you ruined it? It's almost impossible, at least at sub 400hp
It was like that when I bought it. These diesel engines are not as reliable as everyone thinks. However, it shall live again
@@vPerformance Have it done over 1mil miles? Or never serviced?
No only 150,000 miles!
Bad piston rings sealing 😉
Bad glow plug maybe
Injector pump
its a cylindre valve that have a leak
Would that cause white smoke though? I assumed blue for valve seals
Most likely a bad injector
I thought so too - we've just had the injectors serviced and they're all in great shape. We wanted to eliminate that possibility quickly.
@@vPerformance right ok the only other easyfix I can think of is air getting in the fuel lines somehow
@@bh635 would be worth doing a compression check for possible valve seat issue
It diesel
