- The Head Gasket on the LH side decided to give out on my 3rd Generation Wagon. Here is the video I made in the process of fixing it.
I show the whole process;
Engine tear down,
Getting the Engine out of the Car,
Prepping of all the parts,
Assembling the Heads,
Assembling the Cam Towers,
Setting the Timing Belts
Setting Ignition Timing,
Installing the Engine back into the Car,
Etc...
The EA82 engine was Subaru's first Timing Belt Engine (OHC)
Before, with the EA81 and all previous EA engines, they were OHV, pushrod engines.
This EA82 engine is an early version. It is Carbureted instead of Fuel Injected.
Originally it would have a Hitachi Carburetor. Several Years ago I swapped on a Weber 32/36 DGEV Carburetor. I still have the original Hitachi carb with it's Intake Manifold sitting on the shelf.
This model also had Air Conditioning, but that has been removed as it was no longer working and Washington only gets hot in the Summer. This combined with the Weber Carb swap has simplified the engine compartment.
Also, I run the Timing Belts without Covers. This makes getting to the Timing Belts much easier.
The process here will be similar for all 1985 - 1994 EA-82 engines.
This engine was used in the wagon, sedan, coupe, and XT variants.
Dislike sounding repetitive, but way to keep it alive; I get it, we'd be friends.
Well done.
Thank you, glad you enjoyed the video. Working on these old subies is a labor of love
Boxer engine manufacturers love to build dips and valleys to the top of the block for water and coolant to sit in.
Helps you find the random coolant leak on the intake manifold later 😆
@@creativelivingnorthwest Built in feature Lol
This was literally my first car. How in the world did this pop up in my feed.
As in this very car? Or one just like it? They are great cars for sure
@@creativelivingnorthwest same year make model and color. I ran that thing into the ground.
Very informative and straight-to-the-point video. I'll be doing my EA81T as soon as the bubbles in the radiator are flowing out more.
Glad you liked the video. The EA81 is a little different, but the father of the EA82.
The EA81 uses push rods driven from a single center camshaft to time the valvetrain.
Unlike the EA82, which uses timing belts to drive the two overhead camshafts.
You are correct. So hopefully it will be a bit simpler to change the head gasket. Even tho all the research I've been doing on the forums. Many say my issue is more like an intake gasket and not the head gasket. Rare to an EA81T with head gasket issues.
I'll just refresh the whole engine.
@@oczuk32 We have experience intake manifold gasket issues in the past in one of our EA82 engines. Seemed like the engine was running on 3 cylinders or had a big vacuum leak. Sprayed carb cleaner around to try and find the leak while the engine was running... ended up spraying around the intake manifold gasket on one side and found that gasket to be damaged and sucking in air. Replaced the intake manifold gaskets and she was up and running like new
It’s great job man, thanks for this video and slides 👏🏻
EA are fantastic little subie motors that easy to fix, carbs forever, Subaru -for life 🤘🏻
Glad you liked the video! We love the classic Subarus also, such great cars
I got a fuel injection ea82, its really nice
@@Ambrose4k the fuel injection ones are nice, and a little more common on the 3rd generation here in the US. (more years in production)
I'll have another video coming up of this same process on a fuel injection version
@@creativelivingnorthwest that's cool, is it a Subaru xt it comes out of, cuz I got the mult fuel port injectors, I just resealed it, no more leaks
@@Ambrose4k it is from a Loyale. Single Port Fuel Injection... If you have the Multiport Injection that is even different from the SPFI that I'm referring to.
Those Multiport ones are pretty zippy compared to the SPFI version. The GL10 and RX version of the 3rd Gen use Multiport along with a Turbocharger. Very rarely would they have Multiport N/A.
The XT would have the Multiport with Turbo and with N/A a little more evenly in comparison.
I like those XTs, aerodynamic like a jet fighter.
Is your XT Turbocharged?
i tryed designing my own head gaskerts for that motor i got to the point were i could change a head gasket in about 15 minutes to bad i never got the gasket to work on that motor
i was tryin to get more compresion out of it in the end i shaved the block and the heads i had to make a custom intake risers to make up the differance so the intake would fit
damb that m otor was a beast even with the 30 inch tires that thing would out pull the impreza on 28 inch tires with the v2 2.2 motor so much torque
the loyale is off road only these days due to the bodys sheet metal failing that rig is a beast with the duel range it would leave the jeeps on the dust on the trails as long as the rocks werent to big lol
The old Subarus are Beasts, love driving them. It is important to have a backup of parts or the creativity to modify!
Just EJ swap it!!! I did mine and I’ve never regretted it. So easy! Probably easier than doing a head gasket lol these EA82 engines are not very well designed… and they are SPFI. Basically computer controlled carb. I drive it 110 miles a day round trip on my commute and it has been a pleasure
That may be something I'll do in the future when parts for the EA82 are no longer available.
It was simple and cheap to do the headgasket on this engine.
This engine is carbureted, however later models are SPFI like you say. There were also MPFI models available as well as the addition of Turbocharged MPFI models.
Would love the added power of the EJ engine, however this engine is still plenty healthy for now and has enough pep to keep up with traffic
Would you happen to have ea82 spare parts???
I need a (right-passenger side) camshaft case aka cam tower.
@@LowNeverThe I don't happen to have that part. Depending on where you are located I could recommend some Subaru forums where other people may have what you need
@@creativelivingnorthwest that’s cool. I’m in Northern California. It seems like a hard one to find lol
Amazing, thanks for the info!
Glad it could be of help!
Thanks for the video dude !!
Glad you liked it!
Love this video dude. Bought my '87 DL with a blown , your vid was the only one i could find that shows how to remove the motor. My only grievance is that you didnt show us how you got those damn mounting nuts off cuz im killin myself over here trying to get the last one lol
Glad you liked the video. There wasn't really a way I could find to video or photo the engine to transmission bolts and nuts clearly. They can be a pain to get to the lower ones, specifically the one next to the steering column and under the starter. I crammed my arm down under the starter and wrenched from above. Both of the lower nuts from the engine to transmission I removed and installed with a box end wrench.
Another question hehe, are there only 4 transmission bolts in total? And i got a problem when removing the 2 bellow the starter, only got of 2 nuts, i see no way of removing the bolts themselves? Because theres only a nut and theres no visible "other end" off the bolt... Do you get what i mean? Tyty
You can see my other comment, same account
Correct, 2 on the top, and 2 on the bottom of the bellhousing.
The 2 bolts on the bottom are captive to the engine-side bellhousing. When you separate the engine from the trans they will stay in the engine-side bellhousing
@@creativelivingnorthwest well thankyou once again! Scared of breaking something 😁 i have the turbo version so alot is different, and alot of "guy guesses" later it seems good. Found another fnut under the turbo hehe... Thanks again
@@toyotaavensis2754 ah yeah, the turbo version does have a bit more going on. The intake and exhaust manifolds are different, along with the addition of the turbo itself. Luckily most of the rest is the same
Hello! What book R U using?
Thanks for making this I am doing the same thing right now and this has helped me
You're welcome, glad you have gotten some help from it. I'm currently working on another EA82 head gasket on a Loyale. That will become another video with mostly TimeLapse footage.
Donde consigo pieza de Subaru
You said: Where can I get a Subaru part?
Depends where you live and what part you need. Can find them in junkyards, parts stores, or car dealerships
ty for this video!
You're welcome!
I have an 87 gl. Is it possible to replace the camshaft case on right side without lifting the engine?
It is totally doable, it just makes things a bit easier to get to with the engine out... less bending over the fender into the engine compartment.
When putting the cam case back in, lift the side of the vehicle that is being worked on, so that the 4 rocker arms that touch the cam are less likely to fall off. Also assembly lube helps to hold them in place.
Una pregunta, como puedo calibrar valvulas? no vi en ninguna parte que lo hicieras
You said: "One question, how can I calibrate valves? I didn't see anywhere that you did it."
To service the valves you would need to have a valve compressor tool while the heads are removed from the block. It would be a similar process to any other engine as far as lapping and or replacing the valves.
The EA82 engine does not require valve clearance adjustment because they are hydraulic.
The EA81 and EA71 engine would require the lifter arms to be gapped to specification for each valve according to the needed gapping for the exhaust and intake valves.
Well I got the valve cover off. And the left aluminum cast that the camshaft sits in broke. Any idea where I can find a camshaft case?
That is unfortunate. The part that the actual camshaft sits in broke? I don't think I've seen that happen before. Or is it where the valve cover threads into?
Depending on what part of the country you are in, these cars can be found in junkyards like Pick n Pull and the like. Or there are multiple Facebook forums for old subarus, or UltimateSubaru.org/forum where people have parts to sell
Hello.
What was that knocking sound after start? My does it all the time and wont stop.
What book r U using?
The knocking sound was the sound of the hydraulic lifters ticking. They had not yet built up pressure.
The book I'm using is the Haynes Manual for 1980-1988 Subaru 1800. There are different versions of the manual, including a revision that states its for 1980-1994.
@@creativelivingnorthwest Many Many thanx.
@@AdamusPL87 you're welcome!
I'm looking into getting a 87 gl anything serious should be on the lookout for
Look for rust in the body, depending on where the car was driven and how well it was taken care of, rust can really eat the bodies of these cars.
Do the typical checks of the engine and if you can test drive the car if its a runner
@@creativelivingnorthwest well didn't get it had a cracked head an something else done forgot what but sadly didn't get it 😔
@@raymeadows4383 it is pretty common to see cracks between the valves in the heads of these cars. As long as the cracks do not go too far and into the water jacket they will run fine with the cracks between the valves
Thanks for the video. Just did the same on my 79 Brat. It doing the same ticking noise like your did. Do it will go away eventually? Thanks.
Your engine in the '79 Brat is most likely a EA71, right? A similar engine but a bit different...
You have overhead valves in your engine, which probably need adjusting, both intake and exhaust valve clearance to the rocker arms. I cannot remember the tolerances off hand but that info is in the Haynes etc manuals or online.
My engine, the EA82, has hydraulic lifters that are not adjustable. They ticked at first because they had not yet built oil pressure in them.
Thanks for the reply. Yes EA71. I did adjust the valve after I installed the rocket arms.
The book said: intake 0.10mm and exhaust 0.14mm.
Maybe I need to adjust them again…
Thanks for this. What was that loud ticking noise when you started it?
Also, I'm doing the Weber swap and removing all unnecessary vacuum lines. Did you block off your egr? Do you have anything connected to the charcoal canister? And where in the heck is the pcv valve? What vacuum lines do you have connected?
You're welcome.
The ticking is the lifters making noise because they haven't built oil pressure yet. Shortly after that in the video the engine quiets down because they finally built pressure.
I did not block off the EGR but I know people that have and enjoy their engine that way.
I am not running the charcoal canister.
The PCV Valve is at the back of the intake manifold. The LH side valve cover breather connects to the PCV Valve with a reduction T fitting into the Air Cleaner. Make sure to loop the hose up high so that oil sloshed to the left under long sweeping right turns is not pulled into the carb.
The RH side valve cover breather goes straight to the air cleaner.
I only have Vacuum Lines associated with the EGR hooked up and for the advance of the distributor.
@@creativelivingnorthwest Thanks, I've been looking all over the valve cover for the PCV valve lol. I'm also trying to find why it overheats even after I put a new water pump on, found out after a test drive today. I guess a new radiator is next. Good thing parts for these are cheap!
@@MyBacktrail just making sure we are talking about the same thing here; the Valve Covers are on the ends of the engine, left and right, over the camshafts.
The intake manifold is on top of the engine, with the carburetor attached to it.
The PCV Valve is on the back side of the Intake Manifold, directly under the Carburetor.
Check for flow in the radiator after coming up to temperature. Also make sure to burp the cooling system of air. After replacing the pump it is easy to have air trapped in the system.
@@creativelivingnorthwest Right, thanks. I'm used to older engines where they were on the valve cover. I probably sound like a total noob but I've built a small block chevy with a junkyard block and mail order parts. But this Subaru is a new animal for me.
@@MyBacktrail theres all different kinds of engines out there, they all have their differences. You have some mechanical knowledge so you should do fine.
We do all our own work on all our vehicles and just do research on CZcams and automotive forums.
The boxer engine is like a V8, just with 4 cylinders and the pistons laying flat
One question if this is ok, How many engine mount bolts are there? Easy to locate? thanks
There are Two connected to the Lower Crossmember, Four connected to the Transmission Bellhousing, and Two connected to the Pitch Stopper on top of the Transmision. They are all 14mm from the factory.
@@creativelivingnorthwest thanks alot!
@@skitbra1261 You're welcome!
Una pregunta ase seis meses me ajustaron el vehículo igual de la mis ma marca pero estoy viendo que donde va el respiradero tira un poquito de aceite es normal eso solo un lado es que podría ser y otra pregunta tres pistones me tira 150 de precion y en uno mentira 100 que podría estar pasando le agradecería su respuesta amigo excelente video
@@robertogeovannyperes7640 Hello, you said:
"A question six months ago they adjusted the same vehicle of the same brand but I am seeing that where the breather goes, it leaks a little oil, it is normal that only one side is that it could be and another question three pistons throws me 150 pressure and in one lie 100 that could be happening I would appreciate your answer friend excellent video"
It is pretty normal to see oil leaking out of the left hand (driver side) valve cover to intake breather. This is because the positive crankcase ventilation flows from the engine that direction.
The reason that one of your cylinders could have less compression could be a head gasket leak, or it could be that the rings of that piston are more worn out than the others. You could also try a leak-down-test to see what those results bring.
Glad you like the video!
To all the subaru fans out there, going to post here a problem with my EA82 (was pulled from a Loyle,92-93)
I pulled YEARS ago, put the project on the back burner for years. this here is what I had then. (czcams.com/video/Y7o55zRnVGI/video.html )
I am retired now so I started in on this project again. This project was/is for an airboat, as you can see in the above video. Brought a radiator, not OEM,
but I forgot how the radiator hoses was connected to the engine. My radiator is installed On the back side (behind) the engine where the Airboat prop is used for a fan.
I search the internet for how this is done. From my searching, *All radiators are hooked up TOP outlet going to thermostat, Bottom outlet is hooked to water pump.*
What my engine was doing was backward from just that. So I did an experiment.
My Experiment:
Removed thermostat, (so no restrictions) installed hose outlet back on as normal.
Installed small piece (length) of hose on it and the big line coming from water pump.
None of these hose are connected to radiator.
With a water garden hose, pumped water into where the thermostat sits, NO water was/would pumped out through the water pump.
Then, I put the water hose into the water pump line and it immediately stated pumping water out though the thermostat.
This result is BACKWARDs from my understanding!!
*Can someone explain this?*
Am I right
That is correct. The coolant comes from the radiator, flows to the lower hose and into the pump, through the engine, out the thermostat, and into the upper hose, back into the radiator.
i would find another motor one you can get parts for these have all dried up about 10 years ago i bought up all the ea82s i could find just for parts cause they stoped selling them i have enuff to keep my ea82 going for many years but good luck finding those parts today and no im not letting go of mine
good luck
@@ferp420
I am NOT looking for parts!
I appreciate your input, I have all parts I need.
Only looking for hose placement.
@@doesntmatter3068 good cause there hard to find
bottom hose goes to bottom of the engine top hose goes to the top of the engine lol 😀
Que subaru é este e qual é o nome deste motor?
This is a 3rd generation Leone. In the USA they are named by their trim level; GL, DL, GL10, etc.
They are also known as the Loyale in their late USA model and in other places of the world.
This one is a 1986 GL Wagon, with the Dual Range 4WD, 5 speed manual transmission.
The name of this engine is the EA82. It is Subaru's first OHC Boxer engine that uses timing belts. All of their boxer engines before this one used pushrods and were OHV, with a central camshaft. This is the last of their EA series engines. After this, Subaru switched to their EJ series engines used in the next models; the Legacy, Impreza, and Foresters.
Sweet man, I tell my girlfriend all the time "b**** love subes, it's me, I'm b*****"
Love that carb on there. Wish I could find a cheap one.
Going speeduno EFI instead. Old Hitachi carb parts are impossible to find :(
It's hard to not love the old Subies!
When the Hitachi is running right they are hard to beat. I found this Weber 32/36 Kit from Redline on Ebay several years ago.
EFI ought to be cool, that will be similar to the SPFI on the Loyales and later versions of this 3rd Gen.
From '87.5 and later that is what these cars came with.
I have an 87 DL and it won’t stay on if anyone can help with some advice welcome
So it starts up... but wont stay running?
Does it happen after the car warms up?
Need a little bit more info on the symptoms, like how consistent the problem is.
Could be losing spark, losing fuel...
Carbureted engine, right? '87 was a transition year from carb to FI.
Now just crank up but don’t start and is FI some one tell me can be the air sensor
@@juliotorres1736 have you made sure that the engine is getting spark and fuel?
@@creativelivingnorthwest yes
@@juliotorres1736 is the air filter clear?
Are the timing belts still intact and on correct time?
Can I install a turbo on an engine ea71?
I have seen it done on a series 1 Leone Wagon... however I'm not sure how long the engine survived after that
@@creativelivingnorthwest Well, can I change the carburetor system to a fuel injection system?
@@درامالستريمرز it is possible to change over fuel injection from a 3rd generation body that came stock with fuel injection. would just have to have the ecu, wiring, intake manifold, and throttle body/ filter and snorkel.
@@creativelivingnorthwest Thanks I have a question: What causes the smell of fuel in an engine?Ea71
What causes the smell of fuel?
84 was the last good gear for Subaru...
Love the 2nd generation Subarus with the EA81. True, the wagons, sedans, and coupes stopped in 1984. However the Brat kept going until 1987, and the Hatch kept going until 1989!
@@creativelivingnorthwest my favorite was the 1978 old spaceship subi- but the 80-84 was so easy to work on, plus it was not a popular car! They could be bought cheap and easy... 85 began timing belts and the downward spiral of the last true passenger tank a poor person could buy for $1,000 and under in running condition.
I never had a Brat, I'd love a GL wagon with a manual- last year a friend of mine found one in Reno with 65k miles, so they are still out there!
@@GardenerEarthGuy yup, they are still out there. A little harder to find now though. Never had a 1st generation personally, those are getting real hard to find now.
I think the first gen Legacy with the EJ22 was the last good Subaru
