Rocket I was rebuilding a zd30 and my daughter at the time had climbed up a step ladder Up beside the engine. Minus the tappet cover. Telling me "Daddy I fix" then hearing the sound of a tool dropping down inside the timing cover. I rotated the engine around trying to get it drop out the way it went in or drop all the way through to the sump. In the end I had to pull it apart to retrieve the Allan key..
There's something very satisfying about finding a lost washer deep deep down in broken engine you've previously rebuilt.. and knowing it had zero to do with the failure. Nice work lads!
SMALLEST dust particles are the ones that get through and 'dust' an engine. So logically, I think Greg's suggestion of greasing the rubber seals is the only thing gonna help. Turning the snorkle backwards, running a pre-filter, etc, filter out the BIGGEST dust particles. They are good ideas to extend the life of your air filter BUT if you clean/replace your filter regularly, they are not going to do much of anything to keep the fine dust out of your engine.
Rocket Rodney. I would suggest keep the motor and turn it into a stroker. And as for snorkels facing forward or back it won't make any difference with dust at low speeds it's good to have your snorkel facing back but at high speeds it's not because it will cause turbulence on the entrance and your engines gotta worry harder to pull it in. When you are in the bush you can't put a sock over the entrance of snorkel but as soon as you finish you take it off. I used to use a clear plastic dust catcher as it was excellent when you're in dirt roads and bush.
Your more than welcome to rebuild it and send it to me rocket, my 79 got dusted and has been sitting in the shed for 12 months now until i can afford to fix it
rebuild/sell it mate. someone out there will need a rebuilt cruiser v8 especially if the Rocket does the work. as a lot of comments have said ur honesty is refreshing.
I ended up with a spacer and a nut left over after we rebuilt my Dihatsu 20 years ago.. Found the nut went on the oil dip stick bracket about 3 weeks later. Still have the spacer in my spare bolts box unless I used it. Fitted a Donaldson air filter t my 200 after purchase. 100k on the clock , only light off road use and there was a light dust engine side of the factory filter box.
Cyclonic pre-filters (as original installed) can filter up to 80% of particle . . . Ram type is just a raised intake and thus junk in my opinion and not even the manufacturers provide lab test result @@jbjacobs87
I’d look at the Donaldson PowerCore filter system. They are a completely new air box and filter type designed to filter to a much finer filtration and 3 times the filter area. Dusting is a common problem with the whole Toyota 4x4 range, at least for those who use them in dust.
@WholesaleAutomatics Forced induction (forward facing snorkle) creates positive pressure against the filter. At road speed it could possibly disturb the filter seat allowing dust to bypass. The Venturi effect (facing backwards and driving at road speed) creates negative pressure at the filter. At lower speeds the venturi wouldn't be present, allowing the dust to bypass and be draw into the intake. This is relative to atmospheric air pressure of course. Both have the means to disturb the filter seal, allowing fine dust particles to bypass the filter.
I have been waiting for this video! I really like your honest and down to earth style. You're not trying to sell anything, just giving us all great info and real world experience. What would I do with the engine? That depends on budget I guess. On my budget, I would be looking at a new engine given the cost of the rebuild. What if you rebuild it and give it away to a subscriber? I'm sure there is someone out there who loves your work who would like to win that engine to give their cruiser a freshen up.
I placed a cloth over the intake of a Feroza. I started the motor and it ran really well. We went for a drive to a local 4wd track and all of a sudden the Feroza started to rev to 3500 revs. I didn’t know what was going on. We had no tools so I drive it home. When we got home we pulled the intake apart and found the cloth inside the air intake in the butter valve!
I run a Patrol Docta snorkel facing backwards, did Simpson desert and back checked air filter and intake plumbing, still as clean as the day I departed. I do leave a lot of space between vehicles when in convoy to allow for dust to clear as is standard procedure in Army.
Tractors use pre filter dust collection,maybe that's what is needed ? Oil bath air cleaners as used on old tractors ? Atmospheric pressure dictates what's going to go inside a snorkel regardless of it's position ? Also double oil filtration could be used for extreme off road conditions and even the diesel filtration,,is that coping with such extreme conditions ? Imagine a snorkel intake system with a roof mounted large air filter ,the size of a radiator ?? Has heat played a part in this ?
That's something I was wondering about an oil bath filtration would be better at dealing with fine dust or "bulldust" as you'll call it down under. 🙂 It wouldn't work out for some of the extreme off-roading (angles) but on relatively flat terrain.
As an apprentice working on a Bren gun carrier running a flat head Ford V8 I dropped a nut down the inlet. Thank the lord the valve was shut and found the magic of a magnet on a stick.
Hey Rod good video i used to see this all the time with machinery old John rooth had it pegged right with milo you would be surprised how much fine stuff collects in the donaldson prefilter turning snorkel backwards sort of helps but nothing better than a pre filter👍👍
The engine dusted on my old land cruiser. 7 out of 8 cylinders reading around 110psi. I was lucky enough to get a new long block under warranty. Then sold the truck. I have a brand new 79 now and I changed the air box to a fully sealed one with transparent lid and using a oiled pod filter element and stainless snorkel facing backwards. Hopefully I'll get more than 140xxx km out of this one
Absolutley love your content and your honesty, you made a mistake and am happy to own it, in time i will be bringing my dual cab in for a transmission upgrade.
Yep, seen it in other engines. You'll find the rings prob have a little wear on the groove too. Rebore the block and make it a big bore engine, then stick it in a fun trialer and play at home Rod!
Hone it out, new pistons and rings, new Vales and full gaskets set put it back together do a give away or sell It to recover some dollars mate 😊 thanks for the video of the pull down 😊
Oh, I had been waiting for this info. Very interesting thanks. Could be a useful engine once reconditioned to have as an emergency spare as you never know.
Hahaha lucky drop on that washer I unknowingly dropped the wing nut off the air cleaner to a 350 down the carb, had a high rise intake and a big carb, a week or so later it developed a ping in one of cylinders, I didn’t drive the truck just started it a few times over the course of a month or 2 trying to figure out what was going on, it went away one day and was quiet, about a week later it dropped a cylinder and I found a plug beat up and smashed flat, changed the plug no further issues, a while later I put together the missing wing that and what it happened lol 3” exhaust I guess it chewed it up and spit it out
If you haven’t worked out what to do with the engine I would love the opportunity to use the engine to replace my 3fe engine that’s currently in my 80 series. Nice work boys , would love to be able to do what you guys do. Well done!!
Be a really interesting video series to do a rebuild then find a project to drop it into either some high km 200 or 70 series or a swap, build it up a bit and rafle it off for your charity or a charity of your choice. Get industry partners involved to share the cost and showcase their products. Given how expensive modern 4wd are now, i reckon tickest would sell like hot cakes?
Rocket you should do an engine rebuild as you've already gone halfway why not do a conversion and put it into a different car.. Maybe a old HJ47 give another old car a new heart ❤❤
An industrail cyclonic filter goes a long way to stopping dust, on top of snorkle. Even toyotas one works well..If its clear u can see the dust or water if raining heavy biuld such one has to empty it....
I only recently pull a down a 3L engine, and the ring gap was 3 mm. it was dusted That’s like 120 thou it’s only supposed to be 4 thou per inch of bore
throw away swimming pool filter socks make great snorkel socks pack of 5 for $6 from Bunnings and replace it every day and wash it out .. Can also use a smiging of filter oil spray on it to help keep more dust out
Arrgh.. one time I dropped a rocker cover bolt down the timing cover on a Land Rover Td5 engine. It was resting on the timing chain down the bottom and thankfully I was able to fish it out with a magnet..
Really Sad Teardown! & I'm Sorry for your Loss but I personally never travel in convoys & avoid Dust like the mother inlaw ! tip,Cyclone pre filters are a really good way to go because these Toyota V8 diesels are way too expensive to Dust!
I’m still in the market for some injectors (and glow plugs) for my old 79. As for your old engine, I’ve got no need for it and I reckon your auto trans shop may be out of its league to do the work needed to re-build it. Of course, you could out source all that. Air cleaner, if you were using those crap Ryco substitutes in lieu of the genuine filters then, as they say, you get what you paid for. The rubber seal separates from the filter element (last I looked at them) unlike the originals which are fixed to the element. Pre-filters (snorkel socks) assist a bunch to remove a good deal of that errant dust before it gets down the snorkel. kennym
The early vdj79 in 2007 were a bad batch of air learner boxes in original from Japan I personally know many engines that were dusted in roo shooting and pig hunting top lid was being warped under high revs. Toyota ac bou ppl out put cameras on box to record certain ppls egging on a night hunt as they had couple dusted engines in short time. And engines were replaced under warranty

I lost a plastic spray nozzle down the intake while cleaning maf sensor. Give the old girl a rebuild. Bore the block new rings Vavles a resit and new seals . It's a toyota will go for another 10yrs
Got a question for you Rod, I have a AW 30-40LE transmission in my Bighorn (Jackaroo to you Aussies), I have fitted a transmission cooler to it, through the radiator first then to the cooler and back to the transmission. What line is the hot side?, is it the front line coming out of the transmission or is it the rear line?.
Put it in a hj45 or a 80 series or hilux and raffle for charity maybe viewers might get behind cost of build a vehicle for the people by the people (not sure where I stole that saying from) l think it would be an excellent series maybe other industry would get behind it to.😁
What to do with the motor..Rebuild it, have a public auction and the proceeds to be given to a worthy charity / non for profit organisation in Australia that has ben decided between the employees of the business.
If I was you rocket I would reco the engine and keep it as a spare ...I would love to have a spare engine lying around ... if not maybe you could give it to me and I'll put it in my hilux hehe...
The grease tip is good, but toyotas filters let dust through, I wont use anything but a Unifilter now, Toyota cannot make good filters and the airbox's are a lose fit too.
We don't rebuild customers engines and any repairs we do is only on our own cars, but we do rebuild customers transmissions! The engine had massive dust build up.
There’s a lot off carbon build up which is a too much diesel but everyone loves black smoke you’re new engine will suffer the same problem as a diesel mechanic with fuel system experience it’s not dusted sorry
