For some reason, I don't have 80 Series but I have watched all the videos.
VERY THOROUGH! You're the only one on YT working on LCs of this vintage on a fairly consistent basis! Keep up the great work!!
Thank you for all your videos. Not many work on these beast 80s anymore
OTRAMM .. poetry in motion you are. You make it all look so easy. I love how if you have 3 12mm items to take off, you do them when presented. Also breaking things loose with a ratchet, swivels and extensions, saving the life of your impact... Awesome. Thank you for the in depth play by play, this is fantastic. Very well done sir
I own the 97FZJ80, I will never get rid of it.Thank you again love the videos

mate bloody great video, came here as the head gasket on our 80 series just blew today so your video has been fantastic. Thank you so much for posting, brilliant.
Just used this to pull my cams out, thankyou mate, huge help! Boosted my confidence as I haven't touched internals for a good 20 years, the service bolt is a great tip too👍
Great video. very professional, I will do correctly in my 80 series, thanks
Oh Man...that was great. I need to do this to my 80 series in the near future (preventative HG replacement). I am a 'visual' learner and this video was invaluable to me. Look forward to the second video (installation). Thank You for taking the time to provide this. (aka Flintknapper on the MUD forum).
I'm a visual learner as well. I've learned a ton in other subjects watching TH-cam videos. I figured I give back and make videos on what I know how to do. Glad they're helpful.
Thank you so much mate just took off the head on my 105 series time to put the new head on as the alloy if stuffed on the old head
Glad I watched this, was a bit worried valve clash when you was aligning them cams, never knew about a lot of stuff compared to previous fords and Holden’s & sundry that we done over the years, sweet as fella, bonsai mate
Excellent, just Excellent. Keep up the good work Ryan, it is much appreciated.
Thankyou for these videos. They are amazing. Would you consider a series of videos of taking the engine out of a 105?
We didn't get the 105 here. We got the V8 in our 100. I've only ever had to pull the engine out once. It'd be a really hard video to film if I ever had another one come through.
nice work. always, I have my valve seals leaking oil in, so will be doing the whole gasket and seals, and after looking at your video, I think I will pull the motor out, looks so much easier.
It's really not bad to do in the truck. I do them in the truck most of the time
@OTRAMM Thanks, man. What about the rear main seal? My truck has fairly low miles but sat for over 10 years, and all the seals and gaskets are pretty much in need of replacing. Starts drives and runs. Does not overheat . Has a new thermostat and water pump. But my I noticed that when you start it. It smokes a bit. Then goes away. So I took the exhaust manifold off and noticed the exhaust valves leaking oil. Not a lot, but since I'm replacing most of the seals and gaskets, I thought, why not replace all of them and have it last another couple of thousand miles. I already got the gasket kit from toyota.
Beautiful work! My 1 hour well-spent
Love your videos man! Some of the best around for cruiser heads!
Great video! I am getting ready to do this (as opposed to buying a L-Certified GX :D), and the visual aide is much appreciated! The first video I watched steered me clear of some real bad used 80 & 100 series, and as the Lexus Dealer said "I found a diamond in the rough" because I knew what to look for! THANK YOU!!!!! Look forward to refreshing my '96 LX450.
I mean Ryan you are a beast! Haha I'd prefer to start on a junk yard 1fzfe before my own! Damn son. One day I'll pull my motor out. Would love to just take all apart
Thank you so much for the thorough video!!
LC 100 with this engine is my childhood memory.
Otramm you are my hero
Found oil pressure switch with this video 👍
Excellent and very useful. Thank you.
very detailed instructions, thanks. I wish there is one for 100 series even though this 80 series looks similar
All of our 100 series we're 4.7 v8. Luckily they haven't had head gasket issues.
@@OTRAMM the 100 series I have is a strait 6 cylinders. That's why the 80 series looks similar
Thank you for your quick reply
Great job, thank you for help!
Keep the good work man, excellent video bruh !! 👍👌
Thank you very much. This was really helpful.
great video! I tore one down today and it was a big help. when are you going to post the reassembly vid? I get my head back from the machine shop tomorrow.
I'm waiting on this one to come back from the machine shop still. Once it's back I've got to work reassembly in to the shops schedule, then film and edit. I'd guess a week or two until the second half is up.
Amazing video! Thank you for doing these
Very nice working men τελιος μάστορας υπομονετικός
Just did this 3 Weeks ago. Wish I had this video then, being a novice. My head ended up being badly pitted around the valves and just slightly on the pistons with coolant in the engine. Would you advise going through the remainder of the engine since its out? Turns freely but pretty dirty. Sensors on the side of the head melted, so it got hot. Purchased the cruiser this way as a project. By the way I saw a couple of things I did wrong, so thanks for taking the time to make this video and keep up the good work!
If it got hot enough to melt the sensors I'd at least put a precision straightedge across the block deck surface and make sure it's still flat. If you've got the engine out I'd consider pulling the oil pans and plastigauging the crank bearings. You'll have to be careful of the timing chain though since the cam sprocket isn't holding it meshed the the crank sprocket with the head off. Plastigauging is a lot of extra work though if you aren't committed to doing a rebuild if you find out of spec clearances.
@@OTRAMM Thanks for the info. the deck is flat and i'm probably going to go through the engine once I figure it out:)
what great videos, very good, very helpful
This is amazing! Thank you so much for taking the time to share. Just curious what you pay to take it to a machine shop on the average?
The last one I sent to the machine shop was around 180. That was clean, pressure test, vacuum test valve sealing, and mill the head surface flat.
excelent video and excelent teacher and excelent work
great job!👍
Very helpful. Thank you
i think you,re the best ....man
Nice work!
It’s 2.00am. I have work in 4 hours. Oh, and no Landcrusier.
wonderful video series. could you include links to parts you've used?
Most everything came from the factory Toyota head gasket set. We use Toyota gaskets, seals, filters, and fluids 99 percent of the time.
I would love to see a video on how to setup the TPS on a FZJ80. ❤️
We don't adjust the TPS all that often, but I'll see what I can do.
First great useful video I have learnt much from it when watch you remove cam,s you numbered left cam to leave 4-6 till last for removal but by my count you left 3-5 same with right side 2-5 but looked like 1-4 could you please correct me on this issue
The very front cam retainer is already removed before counting back so it looks like it's one off. It looks odd when counting which is why I always double check by looking to see which lobes are evenly spaced pressing down. The factory manual has a pretty good picture but it can still be confusing the first time you look at it.
Thanks for your video. Please show the 1HD FTE engine repair works if you have done.
We didn't get that engine here. We only got gas ones.
So in the event someone mixed up the lifter buckets what would be the process to figuring out which one goes where? Basically checking clearance and pulling it apart to swap buckets over until
It’s right?
I've got a video on checking valve clearance. You'd measure all the clearances. Pull the out of spec shims and calculate which goes where. It's not fun.
Ryan good afternoon, super appreciate your videos and have for a long time. I miss your live chats those are awesome.
I'm in the middle of a head gasket / complete refresh for my 1fz.
How many tubes of Toyota black RTV fipg would you say I would need for both my oil pans and timing chain cover?
I have one too but I thought I should get a second to be safe
Thanks
I'd get a second. I doubt one will do all of that.
@@OTRAMM perfect, thanks, also on the oil pump rotor I got a new one what's up with the triangles? There is zero mention of oil pump alignment in the FSM or on mud.
I made a video I can give you a link if you want to see it but the head gasket was on this time no milkshake or coolant and oil I ended up finding it on number one cylinder leak down I had air in the upper radiator hose cooling system
@@BillyGoatsAdventures I've never pulled the guts out of the oil pump. We just buy the complete timing covers from Aisin.
@@OTRAMM that's the route I almost went then I decided to be stubborn and clean my original timing cover. I want to build a brand new one FZ over the next couple years I'll do a new timing cover then.
Thanks again
Hey I agree with all these comments on you are very helpful and great on the only answers we can find, so thankyou. Im a Toyota guy but this motor is new to me. I have a gasket set and new timing chain set to start this adventure but my question is, do you have a video on pulling the motor and tranny out? Also a video putting the motor back together after the head gets back from the machine shop?
Sorry I just found the rest of the videos on reassembly!
But still, do you have one or know if there is one of taking the motor and tranny out of it?
I don't. We've never gotten around to filming the removal.
Ok new question for you. I brought the head to the machine shop and he told me to bring him both cams and 3 caps for each and all 24 valve lifters and shims. You and the Great book say to label them and keep in order to put back in the proper order. He said that doesn't matter what order if he's going to take the whole head apart and clean, scrape and put back together. Is that right? Or should I bring the book and show him? Afraid that will offend him though.
@@cameron11 the valve shims and buckets have to stay in order or they'll have to be reshimmed. The cam caps are labeled from the factory.
I finished this job thanks to your video! Thank you! I have a few thousand miles on the head gasket now, but since replacement, I have an engine vibration that doesn’t feel normal at idle. I checked engine timing and everything looks good! Any idea what I could have done to cause it while doing the HG?
I've seen it cause strange vibrations if the cams are out of time from one another. Without seeing and hearing it though that's just a guess.
I could not find an engine removal video. I need to replace the rear main bearing too so would like to follow your approach to do both out of body.
I haven't done an engine removal video, sorry.
I know this can be done with the engine in the truck, but it looks waayyy easier to pull the engine out and disassemble.
We usually leave them in but it is really nice to do with the engine out.
Otramm do you have a video walk through of rebuilding the bottom end of the 1fz??
I don't. We just use new short blocks from Toyota.
Hi, I am having an issue with my 1994 80 series 1hdt, to setup the camshaft with the drive shaft,do you have any videos or how to do it?
Thanks
We didn't get the 1hdt here, so no videos on them. Sorry
Great video. I'm debating doing the work my self after watching your video. So do you take out the valves also,and springs ?
I pull the valves to change the seals. It's in a separate video.
Yes!!!!.
Your video was very helpful and educational. I am working on the same engine doing the head gasket . Issue i am having is oil getting into the coolant but no coolant getting into the oil. have you come across this before on a Landcruiser or do you have any reasons/suggestions to why this could be happening? The symptoms are not the same as if a head gasket is blown, nothing is overheating, no smoke out the tailpipe. I have removed and inspected the oil cooler in the block behind the exhaust manifold and it appears to be fine, although I'm replacing it anyway. If not a head gasket blown?? Any ideas to what I can be looking for? Thank you for your help in this matter.
The gaskets in the oil cooler leaking could potentially have the same symptoms. I've heard of them leaking but I've never seen it in person. A cracked head or block could do that also. I'd lean towards the oil cooler since it makes the most sense. The oil is under higher pressure than the coolant so it would leak in to the cooling system.
Love your repair video very detailed useful info. I agree with you about oil cooler having higher pressure then cooling system at least at higher rpms. To test the cooler I plugged 2 ports with my thumbs and had a helper apply air pressure to the remaining port while cooler was submerged in water and did not see any air bubbles. So the mounting gaskets could be possible. I had proceeded to the removal of head gasket repair prior to watching your video, I am in the process of removing intake manifold and I am pretty certain I have removed all the bolts I could get to and it don't want to budge. that's when I decided to look on you tube and seen your video. The amount of time I have wasted trying to do this job with engine in the vehicle, well lets just say, after watching your video, I am going to remove engine. Just the time I spent watching your video I could have removed engine and had head removed. Thank you for your prompt reply to my question. Keep up the good work.
We usually do them in the truck. This one was out because we were also doing a rear main seal.
removed head with engine in vehicle ,used a cherry picker to lift head straight up all went well, until trying to pull cherry picker away the head struck timing chain guide and broke it. any of your videos to do timing chain guide replacement?
@@mattreinhardt4278 I don't have a video on timing chain. I've only had to do it once. I've got one coming in, in about a month so I'll film one then.
i liked the video very informative, however, 42.28 where you rotate the cam to put a service bolt in, i'd be worried that the valves would open slightly and hit the top of the piston.... thoughts??
That's how the manual says to do it. I've always had that concern too so I'm always real light in the wrench in case there's a bind.
I have a 1993 -80 series. Have it since new. First time I see someone so professional. Mine is overheating. 212,000 miles. I was told that coolant is mixing with engine oil. "Head gasket replacement". How much do you charge for a job like this?
I want to say it's between 2500-3k. I'd have to look it up when I get back in town.
Good night. I have a Toyota that works with 24-valve gasoline. A problem occurs when the engine is running every morning, which is that the engine does not start unless you poured gasoline into the air filter. What is the solution to the problem, and you have all the respect and appreciation in awaiting the answer.
There's no way of knowing without doing diagnostics. You'd need to pull codes as a starting point.
@@OTRAMM thank you
Means a diagnostic diagnosis must be made. What do you think if you turned the spark plugs?
@@OTRAMM Means a diagnostic diagnosis must be made. What do you think if you turned the spark plugs?
Great video! I am getting ready to do this. When buying the parts to perform this wiork, is there a complete gasket set you recommend? Or are you going from an OEM parts list? If so, do you know where that list can be found? Thanks for the help!
We just get the "valve grind" gasket set from Toyota.
Hoping youll respond. Is this possible to do while the engines still in the car?
Yes, I normally do them in the truck. This was out for more work so I used the opportunity to film with a good view of everything.
Can you do one of changing the lower intake manifold gasket?
We've never had to change just the lower intake gasket. All the steps are in the head gasket videos. Just watch up until the lower intake comes off and then pick back up as it goes on.
Does oil run through that last hose you took off at 1:04:00? I think oil is dripping from mine where it connects to the head. I have oil dripping from that area and trying to figure out what it is before taking everything apart. th-cam.com/video/9CVK5lr2iHc/w-d-xo.html
What is a rough amount of time needed to remove the head , with the engine in the car. My car has vapour system lpg & it’s a manual. It’s also a 105. Thanks. Love your videos.
No idea how lpg or it being a 105 affects things. I can have a head off in 3ish hours in an 80 series. I've done dozens of them though.
@@OTRAMM ok cool . Maybe I can get it done in a day. Lol. Thanks for the quick reply.
Hi nice video man , I have a question , if you dont mind helping me , I have 1HDT and i just surfaced my cylinderhead and also surfaced my block, will it be okay ? And am about to use the tickest head gasket, the question is will the pistons have any effect on the clyinder head ? Please if there is anything you can help me with please let me know, cause i havent started assembling it .
I don't know. We never got the Diesels so I have no experience with them. I always leave that stuff up to the machinist we use anyway.
Okay thanks for the rply . 🙏🏻
Nice!. Now where is the best place to send the head for a nice work, even porting?
I've never actually done any porting 😁. We've got a local machinist that we send the heads out to. He does awesome work on them.
Hi sir. What model Supra did you replace the head studs with? I want to replace my stretch to yield ones. Can I do this if I have done less than 1000 miles on a new gasket? Regards
I wouldn't change them unless you're also doing the head gasket. Even if you swapped them one at a time you'd still risk disturbing the gasket. There's nothing wrong with the factory bolts, they work fine unless you're adding a lot of boost.
Hi I was wondering if you can get the fuel rail and injectors out without removing the top manifold? I assume it's the same on a 105?
You can on an 80. It's not fun but possible. It's probably easier to just pull the upper manifold.
Great video! Are head gasket failures common with the 80 series?
I don't think they're as common as the internet makes them seam. We do them pretty regularly though, at least a few a year. Of the 80's that come through the shop, the ones that have had head gasket failures are a pretty low percentage.
@@OTRAMM It seems to be mostly EGR equip countries. Aus never got egr equip and they don't tend do head gasket like american's panic over
Mate what’s that small vacuum hose that goes into the manifold called the one next to the pcv hose? Looks like a 19mm head
I think the parts catalog calls it a gas filter.
How many miles on that rig when you had to change the head gasket? Also what mileage is typical for needing this in an 80 series land crusier
I don't recall on this one. We usually see them around 200-250k. Although we've seen several 300k plus trucks on the original gasket.
No need to remove shimmed buckets at that stage. And why don't you show how to remove the cylinder head whilst still in car.?
The buckets have to come out at some point. Why does it matter when. It's really difficult to get clear views in the truck. I took advantage of having an engine out to get clear video. Why don't you show how to remove the head while still in the car?
I'm trying find the part number of that double oring tube that is pulled out of the thermostat feed tube at around 5 minutes.
It's a Toyota part so I just call Toyota for them.
Mine is jammed in there pretty good.
Hey what happens if there is not thread for the 6 mill bolt to screw into to the exhaust cam gear ?
There has to be one.youmay need to spin more not all of the holes are threaded. You need the bolt, the two halves are spring loaded.
OTRAMM okay no worries mate I spin it and see how I go if I have any dramas I’ll let you know cheers 👌😌
Do you think it's worth the time to take the engine out to do this?
We pulled the engine since we were also doing the rear main seal. It was easier to pull the drive train as a whole and do all the seals out of the truck. Since we were going to have to pull the trans anyway it was just as easy to pull everything. The head gasket is much easier to do on a stand. For most head gasket jobs we do them in the truck though.

How doable is this if the engine is still in the truck? Hard as hell or ??
We usually do it in the truck. This one was also getting a rear main seal so it made sense to pull it and do everything out of the truck.
How do you remove the shim from the bucket
Magnet
@@OTRAMM thanks.
Other than decking is there any other work you have the machine shop do?
I usually have them do the valve stem seals too since they're a pain. They also pressure test for cooling leaks and vacuum test valve sealing.
@@OTRAMM gotcha. Do you typically do any valve lapping even if they are in spec, or is it just something you do on a case by case basis?
@@grahamsproductionz we usually leave them alone.
Not sure if there was enough reason to take that engine apart. Everything looks clean and still in working condition. What was wrong with it?
It had a blown head gasket, and warped head.
Quick question; I may have missed it in the video, but why is it going to the machine shop, what's getting done to it? Thanks.
Nope, you didn't miss it. I totally spaced on explaining it. I send all the heads we pull to the machine shop. They pressure test them for cooling passage leaks, vacuum test the valve sealing, measure for warp and them machine a nice smooth warp free surface back on. They usually only skim a couple thousandths of an inch off.
@@OTRAMM Did they put new valve stem seals in? Did they do a valve job? Do you check the valve clearances or did you have to change out any shims? Great video. Thank you. It's helping a ton.
@@bob82pigdog I did stem seals on it when it came back from the machinist. The machine shop vacuum tests valve sealing. I've never had them recommend a valve job so I've never had them do one. I check all the clearances when going back together. Without doing a valve job it's rare to need to change shims. I usually see it when someone's been in there before and gotten the shims out of order.
@@OTRAMM Awesome. Thank you. I'm feeling good about not having to pay for a valve job or do the shims now! My compression numbers are good, except for one cylinder of course.
@@bob82pigdog I'd still check all the valve clearances to be sure. Nothing worse than a misfire after you put it all back together.
How much would you charge for doing the head gaskets at your shop?
If all goes normal it's right around 3k
@@OTRAMM Thanks, love your channel btw m8!
All my injector connectors retaining clips snapped off😂
I just took mine off today, and snapped 3-4 of them. What did you end up doing?
Dave S. I just plugged them back in and hoped they didn’t come out. Over 5000kms so far and haven’t had any issues. If I had the time and coin I’d have bought new connectors but they were hard to find and expensive last time I checked.
Wow this guy is a juniors
HI There, How many miles were on this motor? Thanks
It's been a while but I want to say around 250k.
@@OTRAMM Thank you sir. Love your videos. Im about to pick up a 96 LX450 with 250K miles and will be doing HG as PM. Im nervous to do the job but as a mechanic told me, "You cant take the mechanic on the trail!". I have a GX470 at the moment but the 80 series wont let me go.
@@OTRAMM My FJ80 had been sitting for 7 months, had tranny solenoid issue. Now that it back together it appears that the head gasket has let go. milky stuff in valve cover and gurgling in the coolant expansion tank,, was going to have a local shop do the work..have enough other project to get done. The shop said not a good idea with 240K said that head gasket replacement will put too much pressure on the lower end and will probably lose the bearing within a year. Does that sound legit or bs? BTW great video on the tear down
We've done them at close to 300k without issue. The local shops reasoning makes no sense.
This a diesel??
Nope, gasoline.
How did you get the heatshield bolts off without a single one snapping?
WITCHCRAFT!!
I know, right? Those always snap!!
Real mechanics rebuild fake ones replace.
