Hello all!

First post here!

I am terminally paranoid about the 1VD-FTV In my 2010 VDJ76r. While the engine is great, its strong and runs beautifully - 10.8L/100km highway driving! I am terminally paranoid about breaking it!

If the time does come to rebuild the engine or replace it, I was wondering how hard it would be to replace it with the legendary 1HZ instead of a new or reconditioned 1VD.

I'm looking to save money on a reconditioning (about $22,000AUD in Australia) and I have seen you can get 1HZ engines for less than $5,000!

I know you can buy the HZJ76r in Europe which is the same vehicle as mine but with the 1HZ, so surely it can be done?

Looking to keep it manual, not worried about converting it to an automatic.

Does the 1VD-FTV have issues (that would justify you being paranoid)? Worrying about things unnecessarily can cause wrinkles. 😊

Not really, it runs like a dream as I said. A little black smoke every now and again on full throttle but that's it.

I did an oil change recently and there were some tiny pieces of metal in the oil but my mechanic said that it's okay (especially since there was nothing in the oil filter at all). Picture attached. There were about 7 of them, and since engine is at 350,000km apparently it's normal for there to be a little...

I believe some of the Middle Eastern countries got the HZJ76 so dropping in a 1HZ should be fairly straight forward.
 
Here are some pictures of what I found. Oil filter completely clear, nothing on it at all.

What are your thoughts? I cant really jistify a $22,000 rebuild.

Hopefully your fellow mates from down under, who have actual experience with that engine, will chime in.
😊
 
I very much doubt you will get a 1HZ engineered into a VDJ7x because the engine was dropped for emissions reasons.

You could put a VD into a 75 or narrow nose 79, as it's a newer engine, but you can't put an older engine (easily) into a newer chassis.

Other Australian based member will chirp up, but this is my basic understanding.
 
OP, just looking at your oil, that is absolutely filthy for a 1VD. You need to do a proper oil flush on that engine and get rid of that carbon build up. Look up Cost Effective Maintenance, their suff is the only snake oil that is any good. Grab yourself some of this gear and go to town with it. Their decarboniser is worth it as well.

I've gotta service mine next week, I'll take you a photo of how my oil looks.

Regarding the metal, what did the sump plug look like? Are those chunks magnetic? Because if they are, they're massive. Your oil filter should give you a better indication, any sparkles in it? From here I must say those look more like chunks of carbon than metal.

As far as swapping a 1VD for a 1HZ goes, it can't be done here in Australia for said reasons above, regarding compliance, your only option is to sell the VDJ76 and go buy a HZJ78 (Troopy). The 76 platform never came with anything other than the 1VD-FTV here in Australia.

I am not sure what builds your paranoid state regarding the 1VD. Service it religiously, do the terrain tamer airbox insert mod, maybe a second fuel filter, clean the intake every 100,000kms (if you don't want to block the egr which is choice number 1) and thrash it. You won't break it and it won't let you down. I personally know of 5 still being thrashed with 500,000+ kms on them.

Toyota doesn't build junk, and certainty isnt going to put unreliable stuff into their flagship line. I would go as far to say that the 1VD-FTV is the best diesel engine toyota ever put in a landcruiser. (1HD-FT/E is a great engine too).
 
Sorry to be this guy, but why? A 1HZ is a downgrade in pretty well every aspect other than downright simplicity over a 1VD

I've seen several 1VDs with 500,000+ km that have been regularly maintained but never opened.

Secondly, I second the comments that the oil is filthy and needs attention.

Thirdly, please confirm if those particles are magnetic?

Hello,

Okay I've taken that all on board.

The particles are indeed magnetic, lucky I saved them (picture attached).

It has a custom air filter in it designed to stop dusting, and it's doing very well.

Im a bit confused as to what could be causing such dirty oil?

The sump plug was clean when I took it out. I had a look at it and was happy with it being clear.

Also, every now and again on the oil filter there is a little bit of sparkle. They are only on one side of it though?

FYI this was my first ever oil change.

It is, as I have one myself ;)
 
Are there some recommended oil analysis labs in Australia? I would highly recommend sending in a sample at your next two oil changes to get tested for wear metal content, among other things. This is a good way to get an indication of the internal wear in your engine and it's overall health.

Also, how long had it been since the oil was last changed? I have no experience with the 1VD, but for any newer common rail diesel that is pretty dirty unless the oil had been in there way too long.
 
The oil was last changed 11000km ago buy a mechanic at a 4x4 garage he reckons the engine was in great condition.

I know I left it an extra 1000km , but I'm going to start changing it every 5000km and filter every 10000km from now on.

Also, can I use the Nulon engine flush or the luquimolly one? Is it even advisable to do an engine flush if there was metal in the oil? There wasn't much metal at all, even the filter I could have counted on 2 hands the amount of sparkles from almost invisible pieces of metal.
 
How many Kms has this motor done.
Those bit of metal don’t look right. One of them looks like a chunk of rust. They do not look like shavings from a wear surface.
Do you have a magnetic sump plug. If not then I would recommend one. That will collect all the free metal pieces in the same place and make getting them out easier.

It's done about 350,000km.

I'll go get one today, should I change the oil again and do a flush? It's been maybe 100km since I changed the oil.

I did hit some stuff with a hammer while the drain pan was under the car and I also rounded the socket on the filter remover tool above the drain pan. So I guess there is a small chance the metal could be from that... :/

Dirty oil is just from too long between oil changes. I can't find it but there is a Toyota manual that states to change the oil every 5000kms when under heavy load. Oil every 5000kms and oil and filter every 10 is my blanket rule.

The newer Toyota engines quite commonly shed chunks of casting from within the engine. The 1VD has been known to do this, so has the 1hz, 1hdfte and so on. It could be the case here. Not saying that it is, but you might not have any serious internal issues. If the 76 is new to you, i would do the following:

Order from toyota:
New filter housing (over time the sleeve can get loose and if it falls out the filter crushes under suction from the oil pump essentially starving the bottom end of oil flow)

New pickup. They are plastic and are a serviceable item. That's why the small black pan is on the sump so that you can get to it. They have a mesh filter in them that can sometimes get loose and fall out (rare but it's a cheap part)

Flush the engine oil with any engine oil flush, grab 20L of the cheapest 15w-40 that you can find and do it twice. Pull the filter both times because that will allow another 2-3 liters of oil to flow out. Afterwards replace the oil and filter with high quality gear and check again in 5000kms.

Lastly always use genuine parts and filters where you can. 9/10 times the price is comparable or better and the quality is of a much higher standard.
