This is the only way he would do it. I would not even want to do this and I have swapped the old Subaru ej25 engines and did headgaskets. but sometimes a chunk of money convinces us to go against better judgement.😂
I would expect diagnosis, what Ivan does, as higher skilled work, so has higher hourly rates than a regular part swapping mechqnic. So spending his more expensive time on something many other mechanics can do cheaper would not be honest for his customers. But here it seems his customer insisted to pay the diagnostic rate for the work. But 14 hours, that is the heck of expensive repair...
I really enjoy watching your videos and your use of all the new diagnostic equipment and procedures. I'm retired from automotive repair business now and have seen a lot of changes in diagnosis and repair procedures, but one thing still holds true, sometimes you have to go back to the basics. Too many times people (techs?) will assume that a problem is caused by one of the electric components when actually it's a base engine problem (compression). Enter the parts cannon!. When I first started out in the repair business, I remember a seasoned mechanic diagnosing a burned exhaust valve by holding a piece of paper over the tailpipe, everytime the engine would miss, the paper would be drawn into the pipe. Love your channel.
Ivan... glad you took it on. The customer is worried and you are honest and thorough. It's a big job, no doubt but I can understand it. You're a good man and a good heart!
I've seen a handful of these with broken valve springs. Be prepared for a fight getting the timing cover off and for hours of cleaning Fujibond. Make sure you have all fasteners out and don't pry on the timing cover past the cylinder block. You will break the aluminium cam caps otherwise.
Great quick accurate diag as always , your time is better spent on high level diags not wasting your days pulling engines out that any mechanic can do . It's hard to say no to customers make sure you charge your full rate for every second of labour that's not a cheap job the customer knows your honest I don't blame them .
Yeah I don't mind doing bigger jobs occasionally, but in this case when the instructions say pull the engine and flip it over in a special stand, it sounded ridiculous 😆
Living in the snowbelt, we loved Subarus but got tired of their expensive "quirks." It seems no generation of Subarus is without some sort of expensive fatal flaw. My daughter managed to nurse a 2001 Forester to 475K on it's original head gasket, and we figured that we used up several lifetimes of Subaru-karma with that one!
yep old was better with these, we got 2 2000 and 1 2003, 2 older ones been real good and still got plenty life left, after the 2005/6 SG they became worse thanks to emission equipment and declining build material/part quality, The diesel early diesels was a disaster. Glad I stuck with old ones, buying newer is buying problems ...
My friend had a 2011 Forester manual close to 75 k. The fork for the clutch broke inside the housing and after contacting customer service they split the cost. My friend paid for the parts and Subaru took care of the labor. Not as good as Toyota's customer service but much better than other brands.
I can remember in the days of leaded petrol (1970's to 1980's), when Subaru made front wheel drive cars, and introduced the idea of 4-wheel drive in an ordinary car, and were very popular for towing small boats and were very efficient on the boat ramp. As well, gearboxes were very strong. They all used the 'boxer' engine, and over a period of time (past the 100,000 mile mark) exhaust valves would 'crack' and/or burn out with bromine fuel 'scavengers' in the petrol. This also happened with the air-cooled Volkswagen beetle rear mounted engines, which were easily removed for working on. With the later versions using fuel injection, and unleaded petrol, the seal in the injector tube would 'crack', causing a lean mixture to that cylinder, but very difficult to notice until an exhaust valve has burned out....
You will find that the engine still has to be removed in an older Forester because my brother dropped a Valve in his EJ20J powered 2000 model Subaru Forester a few years ago when him & my dad travelled 600 kilometres (360 miles) to see my grandmother who now lives in a nursing home, they were on their way to see her. The cause was the use of LP gas & my cousins husband who did his apprenticeship with a Subaru dealer had to remove the engine to remove the cylinder heads,he sent them to a local cylinder head reconditioning shop who replaced the valve seats,fitted new valves & valve springs. He also replaced the clutch & oil seals while the the engine was removed & charged my brother about $3500 AUD which was almost cost price since he was family !
Hey Ivan, haven't seen your wife in one of your videos in forever. Where has she gone? You are WAY too nice! "Customer talked me into doing the repair." NO, don't walk away......RUN!
I had a chevy sonic recently that had 3 or 4 exhaust valves torched, half of the valves from seat to stem were completely melted. I assume timing jumped a tooth or two in order for it to effect multiple cylinders. Usually I'm dealing with the ecotecs. In the past 6 months I've had to have replaced at least 100 valves on the gm 2.4l engines due to being bent from timing chain failures. Chrysler 3.6 failures are also up there in consistency with their failures. I keep camshafts, rocker arms, and lash adjusters in stock because there's usually at least 1 a week, sometimes more, that come through the door. Don't know what it is with the designs of these engines, is it engineering or are customers just that abusive with their vehicles....
Hi man ! Its possible to do it without taking the engine out. But its a pain to torque the head and adjusting the valves. Olso pay close attension to coolant crossover pipe o-ring( the intake plenum will be off anyway) they sweat coolant often. 👍
Yeah - I keep thinking that. A lot of TH-cam mechanics like Humble Mechanic and FordTechMakuloco have built large shops on their houses and I think Eric the Car Guy is planning to do that for his workshop when he returns. He has plenty of room to do it but getting a contractor must be a son of a bitch at the moment.
Is Subaru becoming the dodge of Japan? Nissan is clearly the Ford of Japan. Sad to see this problem coming from such historically high quality manufacturers. Perhaps it's just an anomaly and Japan still makes the better cars. I can't believe you accepted the repair. Will be watching it intently. Thanks ivan for posting these things.

My wife loves her suburu- her first one. But I'm shocked about the fragile paint, the poor upholstery and generally lousy fit and finish. Add the insanely complicated design overall, I don't know how they got the reputation they have.
Good one Ivan. We get to see you either do an engine removal on a Subaru or more likely see you work out a way of doing the valve replacement in the vehicle. Either way it will be great! It would be nice to know if it was a faulty valve from the manufacturer. I have never heard or seen of a valve failure like that before. You would have thought it would have to have been hit. I hope for your customers sake you don't find other damage on the head, bore or piston.
Always love a good cylinder transducer waveform. You should show the group what a VA sensor looks like hooked up to the exhaust and one in the tail pipe. I started with that strategy because all the trouble cars come in hot off the hwy. So plumbing a VA sensor on the intake and exhaust pipe is easier. Then I can tell the customer to go away because I need a day alone with the car. My diagnostic life is all about buying time and getting the customer out of the lobby.
I have a 2009 Forester and I'm detecting some exhaust noise like that. I'm hoping it's just a gasket. I'll have to pay attention to the idle. I do not like these cars. The engine is a glass cannon though the rest of the drivetrain seems solid.
Hey Ivan, the guy trusts you to do the job right. Anyone who has watched your videos would feel the same. Kudos to you Ivan, many thanks for all you uploads, from Nr Liverpool UK.
I really dislike changing spark plugs on these damn subaru cars. Had a misfire one time due to human error when installing new plugs. One of my techs damaged a plug while putting it in, had me chasing my tail all day to find out that the plug was crack upon installation.
@@PineHollowAutoDiagnostics the BRZ requires a bit more than a wobble. I had unbolt the engine and lift it a bit. Thank goodness the only need replacement every 100k. I know Subaru states 60 but the iridium hold up well
@@jeffreygoss8109 I expect the 100k life of the plugs is why engine design has gone that way. Plenty of cars you need to remove the intake/cowl etc. In teh oldn dayz plug changes were far more regular.
That was my thought too. When the valve can’t contact the seat to dissipate the heat it gets super hot and can start to melt away. Whatever it was, it’s all burned away now!
I know that the older belt driven cam Subaru boxer engines with turbo's were known for eating valves. But those were fairly easy to rebuild. I have not seen this happen on the newer ones either.
I work in Subaru service. I have never seen an FB with a cracked valve. Never really see FB's with problems other than oil leaks which is typical. These 2014-18 model Foresters are decent. I've seen a few with manuals, they aren't that common tho. Common i hear them come in with exhaust leaks because of a clogged cat. Also some of them burn lots of oil. Hey it's what makes a Subaru a Subaru. I'd still take one of these over a new Turbo model in the long run. The Turbo FA24F come in all the time with oil leaking at less than 20k miles. Either from the lower oil pan or from the oil level sensor. On the oil level sensor jobs the turbo needs to be pulled off to fix.
Great insight, thank you! These are just approaching the 120k mile mark so I bet this isn't the only one with this issue... Maybe a bad batch of valves? 🤷🏼♂️
@@PineHollowAutoDiagnostics Maybe the engine got too lean? Or maybe the valve got stuck open because of a defective spring? which i do know Subaru had a valve spring recall on their FB/FA engines. It was mainly on the 2.0L tho. Common on the Impreza, Crosstrek & BRZ.
Ouch 😔 Have had unfortunately burnt valve experience with my previous old 02 Ford Focus 1.6 due to oil consumption, long story short i ended up to get a second hand 1.6 engine with relative low miles on it and that was a good engine. I hope you had a happy 4th of July Ivan 😃🎉 Great video 😃👍
Very good Ivan. Your repairs are a good education for people that don’t work on cars as to what is involved doing the big jobs . If you’re doing this engine head TARE down every day it comes as routine to a tec . But still labour intensive. Looking forward to part 2.
Sounds like my EJ253 after I floated the exhaust valves into the top of the pistons. They apparently don't like 10k RPM from a 2 -> 1 money shift at 50 MPH. All 8 got bent, but on one side only one in such a way as to not seal, slowly burning away around a couple spots on the edge. I wonder if there's more to this story... However, 2015 outback with the FB25 and TR580 at 91k miles, no problems.
Just started this mini series. Could you give me some insight on why the "pop pop pop" from the exhaust indicates low compression? Love your videos. Keep up the great work.
Newer engines from Subaru are known for burning valves and also breaking the valve springs, Toyota 86 that it is the same Subaru BRZ all have that issue from day 1. So Subaru reliability keeps plunging like GM. Now they barely make the 100K miles before head gasket job, valve jobs, plus the multiple times of valve cover gasket replacement. That is why keeping a Subaru all you need is Love... and lots of money.
What a strange defect in the valve. It looks to me more like a manufacturing problem rather than a burnt valve. How many valves have you seen with butt cracks?
Ivan, with your explanations I think getting pretty good at understanding the waveforms you've included. I'd say I'm close to buying at least a two channel Pico scope for myself. I think your customer is just tired of the run-a-round and JUST wants his car fixed. Looking forward to seeing your magic in the next video. Thanks for Sharing!
Consider making sure the valve is rotating. In aviation that’s what is starting to be seen as typically causing burned valves, not mixture or anything else, but the valve needs to rotate while running to ensure even and consistent contact and heat transfer from the valve to the head.
They don't make them like they used to. I had a co-worker with a manual Subaru with the same issue. Very strange that the ones with manuals seem to have more problems.
In 1973 we pulled them out by hand in 45 minutes just to prove how tough we were. The exhaust manifolds made perfect handles ‼️ (No AC,PS, manual choke-easy) Probably why my back is worn out now. Young and stupid tricks.
I always wish to be this knowledgeable, am in Africa and to get this level of skills is very expensive.the diagnostic s are on another level. I admire you work you and diagnosedan are good technicians
No need to pay big money. Ivan, Eric O, Scanner Danner and others on here provide for us. In exchange, give them a thumbs up and subscribe. Scanner Danner sells a diagnostics book as well as online classes that are much much cheaper than schools. No need for expensive tools either. Mechanics were around before we had access to the expensive diagnostics tools.

Hmmm, I have a customer with a 2017 stick shift forester, guess I should be expecting some engine work down the line. I already hav3 had to replace the rear wheel bearings on it.
Great diagnosis1 And they talked you into the repair - can't wait to see that! Wonder why it seems the common factor of these failures is the manual transmission - maybe people lug them or drive the RPM's too high?
I have a CVT (my first automatic) 2013 Impreza. Does this Forester have an FB engine like mine? Did you look at the other exhaust valve? Subarus have four valves per cylinder. I'll definitely watch part two to find out why cylinder head work takes 14 plus hours!!
Seen the split valve before. Fixed one in my moms 1956 Pontiac. This would have been in the early 60's. Took heads to machine shop valve grind , new valve and one inner valve spring $25.00
I would even say the exhaust noise (the sharp "pif-pif-pif") gave quite clear clue there is high, combustion, pressure escaping into the exhaust. And that could obviously go only via a valve not sealing properly...
@@PineHollowAutoDiagnostics But the point is it won't sound that distinct sharp way. But by itself it may just suggest where to look further for true confirmation.
@@annaplojharova1400 it had a curious intermittent high pitched whistling sound however... Almost like a belt squeak. Sound disappeared after repairs. I think that may have been due to the burned valve!
Nah, on my 1940 Chev. truck 6 cyl. I had to get a head from the junkyard ($10), take it home and take out the valves, find some valves that weren't burned, I think from a 1941 head, grind them by hand, (12 valves) reinstall them, slap the head on with a new gasket, align the timing gear and adjust the valve lash (.08 to .015) then add water. 14 hours total time. Start her up and drive for 5 years. No oil filter and air cleaner was an oil bath with splash type cyl. lubrication. (Not a tall tale). I also spent 8 hours pounding out the left kingpin and replacing it, but that is another story. I hope my twin brother doesn't get mad because I left him out of the story.
Question On a 2001 Toyota Corolla, does the ECM monitor the door lock circuits and what voltage ís it on the switch side of the circuit? I had a compustar alarm installed but at times the system does not unlock the doors. I am thinking on how cartoys wired it up, the alarm system is sending 12 volts into a 5 volt reference circuit, not allowing the alarm system to unlock the doors at times. When it is doing it, with the doors closed, the power door lock switch is disabled on both front door switches just on unlock. However with the driver's door open, the lock switch will work. I know that the courtesy light switch is also used on the driver's door for the lock circuit. . I am thinking of relaying the circuit on both look and unlock circuit to separate the alarm system from the cars electrical system.
I hate when that happens. You have no intentions of doing a job and next thing you know you are elbows deep into it. Happy fourth to you and your family. I always loved it when people asked me if we had the fourth of July in Germany. I told them sure since it doesn't go from the third to fifth.
I wonder if it is burning the exhaust valve from a lean condition when you leave off the throttle and use engine braking? That might be why is is only showing up in manual transmission vehicles. I haven't had to deal with one of them yet so I will be looking forward to the repair.
A couple of thoughts without seeing part 2: a) I don't think Subaru will cover it, they'll claim age and mileage b) It would be cheaper to find an engine from a totaled car with about 60-70K miles on it.
I am a new driver and bought an old car from a local dealer. Now I found that this car has a gasket and wheel bearing issue. Is it worth fixing the head gasket and timing component in the 2010 Subaru Forester(150000 Kms)? or Trade?
This is why I charge buy the hour not buy the book. I work on American and Japanese cars only been doing it for over 55 years. Learned my lesson early on when you work on that many models hard to meet the book time. That would hard to do in 14 hours. I would also due both heads just to be safe. Doing one head may cause balance problems within the engine. Good Luck 👍
Yikes. Never saw a valve crack just like they, but have had a pizza slice taken out of one before I had on a Range Rover. And you got snookered into doing the job? Man Ivan, she must have been a looker! Hahahaha.
Probably epic diag. I never see cracked valve. Amazing. And You’re really taking Subaru’s job??. Oh Ivan.I can’t wait! Looking forward to more episodes lol 😁.
Mauals can just be operated differently to automatics. Like riding the idle governor in high gears, or running very low loads in high engine speeds - an auto wont let you do that. If the manufacturer then simply added a manual as an afterthought, problems can happen. Typically, a different gearbox requires new calibration of the control unit.
Oh man you got suckered! Who runs your business you or the customer haha... See you in part 8 😅

Hey it's what makes a Subaru a Subaru. I'd still take one of these over a new Turbo model in the long run. The Turbo FA24F come in all the time with oil leaking at less than 20k miles. Either from the lower oil pan or from the oil level sensor. On the oil level sensor jobs the turbo needs to be pulled off to fix.
Great insight, thank you! These are just approaching the 120k mile mark so I bet this isn't the only one with this issue... Maybe a bad batch of valves? 🤷🏼♂️
@@PineHollowAutoDiagnostics Maybe the engine got too lean? Or maybe the valve got stuck open because of a defective spring? which i do know Subaru had a valve spring recall on their FB/FA engines. It was mainly on the 2.0L tho. Common on the Impreza, Crosstrek & BRZ.
@@RicardoPCGamer We'll take a close look at the valves in Part 3 :)
Ivan happy 4th of July. Looking forward to the repair. Thanks for sharing 👍
25 hours labor at least. Pulling engine isn’t a walk in the park. Looking forward to the next video!!
Ouch 😔 Have had unfortunately burnt valve experience with my previous old 02 Ford Focus 1.6 due to oil consumption, long story short i ended up to get a second hand 1.6 engine with relative low miles on it and that was a good engine.
I hope you had a happy 4th of July Ivan 😃🎉 Great video 😃👍
Very good Ivan. Your repairs are a good education for people that don’t work on cars as to what is involved doing the big jobs . If you’re doing this engine head TARE down every day it comes as routine to a tec . But still labour intensive. Looking forward to part 2.
Sounds like my EJ253 after I floated the exhaust valves into the top of the pistons. They apparently don't like 10k RPM from a 2 -> 1 money shift at 50 MPH. All 8 got bent, but on one side only one in such a way as to not seal, slowly burning away around a couple spots on the edge. I wonder if there's more to this story...
However, 2015 outback with the FB25 and TR580 at 91k miles, no problems.
Very good diag Ivan. I really liked this series. This one was something and very interesting from beginning to end. Keep up the good work my friend.
Turning away a customer is hard but sometimes the right decision. I hope this goes smooth for you
Just started this mini series. Could you give me some insight on why the "pop pop pop" from the exhaust indicates low compression?
Love your videos. Keep up the great work.
Newer engines from Subaru are known for burning valves and also breaking the valve springs, Toyota 86 that it is the same Subaru BRZ all have that issue from day 1. So Subaru reliability keeps plunging like GM. Now they barely make the 100K miles before head gasket job, valve jobs, plus the multiple times of valve cover gasket replacement. That is why keeping a Subaru all you need is Love... and lots of money.
Going to be interesting and educational to watch. Your determination always amazing!
What a strange defect in the valve. It looks to me more like a manufacturing problem rather than a burnt valve. How many valves have you seen with butt cracks?
NOOOOO! You are too nice Ivan!! That's a big job. Can't wait for part two! lol
Ivan, with your explanations I think getting pretty good at understanding the waveforms you've included. I'd say I'm close to buying at least a two channel Pico scope for myself. I think your customer is just tired of the run-a-round and JUST wants his car fixed. Looking forward to seeing your magic in the next video. Thanks for Sharing!
Consider making sure the valve is rotating. In aviation that’s what is starting to be seen as typically causing burned valves, not mixture or anything else, but the valve needs to rotate while running to ensure even and consistent contact and heat transfer from the valve to the head.
Great comment 👌
That Teslong resolution is impressive. Another great video, can't wait for the following repair.
They don't make them like they used to. I had a co-worker with a manual Subaru with the same issue. Very strange that the ones with manuals seem to have more problems.
That's a very easy engine to remove/install and the head is pretty straight forward to
R n R .
In 1973 we pulled them out by hand in 45 minutes just to prove how tough we were. The exhaust manifolds made perfect handles ‼️
(No AC,PS, manual choke-easy)
Probably why my back is worn out now. Young and stupid tricks.
So that’s how valves are made it’s dividing into 2
or maybe that cylinder wants to be multi valve
Nice work
Pulling the motor is a piece of cake, you'll be glad you took the job. Easy money.
The hard part is flipping it on it's side without the fancy Subaru engine stand lol
Good luck Ivan. I love your channel man. And i respect you very much.
Good luck with the repair. I hope it goes smoothly for you.
Wow, he roped you into doing the job! Looking forward to the subsequent videos.
I don’t know if you know this but if you hold the throttle all the way down on subarus it has a clear flood mode
Happy 4th of July to you and your wife man. You deserve it.
Thanks Jeremy, you too :)
I always wish to be this knowledgeable, am in Africa and to get this level of skills is very expensive.the diagnostic s are on another level. I admire you work you and diagnosedan are good technicians
No need to pay big money. Ivan, Eric O, Scanner Danner and others on here provide for us. In exchange, give them a thumbs up and subscribe. Scanner Danner sells a diagnostics book as well as online classes that are much much cheaper than schools. No need for expensive tools either. Mechanics were around before we had access to the expensive diagnostics tools.
@@Pr0ph3cy-k5z 👍
I can't imagine going to a dealer if I could convince Ivan to do the work, lots of high-grade Vodka!! I do not know of anyone as intelligent, hard-working or trustworthy as Ivan. Gals you helped the owner out Ivan you are a true America.
Would have liked to have seen where you put your scope in. Having an issue with a 2012 outback
Exhaust valves was an EJ problem. That's strange.
Make sure if you are going to proceed, that you allow yourself enough time. You don't want to be doing this job "for free."
Step 1) Remove engine from vehicle.
Ivan "This is why I don't want to be married to this car"
In the end, Ivan's going to a chapel and gonna get married. To be continued...
Ivan Ever Since You Worked On My Subaru ………… Forever 🤪
Hmmm, I have a customer with a 2017 stick shift forester, guess I should be expecting some engine work down the line. I already hav3 had to replace the rear wheel bearings on it.
Ivan, Ivan, Ivan! What's going on? Your excuse for NOT doing the job sounded so reasonable!
Sounds like about 3k plus, and at that point it would make sense to do both heads, and a complete timing job. So that would push it to over 5k
"talked me into doing repairs" lol, Ivan - can't wait to see that video
Great diagnosis1 And they talked you into the repair - can't wait to see that! Wonder why it seems the common factor of these failures is the manual transmission - maybe people lug them or drive the RPM's too high?
I have a CVT (my first automatic) 2013 Impreza. Does this Forester have an FB engine like mine? Did you look at the other exhaust valve? Subarus have four valves per cylinder. I'll definitely watch part two to find out why cylinder head work takes 14 plus hours!!
Customer complaint: "Too many Tr**p flags in the shop." 🤣 🤣 🤣
VIEWER complaint: "Not enough Tr**p flags in the shop." Free speech and PEACEFUL protest. 🤣👍
Actually most customers love it haha
Seen the split valve before. Fixed one in my moms 1956 Pontiac. This would have been in the early 60's. Took heads to machine shop valve grind , new valve and one inner valve spring $25.00
Ohc makes it a little trickier. Need to get the valve lash adjusted properly.
Good man, you have that done before supper lol .
Can be done in frame but they quick pull once done a couple .
You will nail it. Will be fun to watch
If I were the customer I'd want Ivan to do the repairs too.
Me too!!!
I would even say the exhaust noise (the sharp "pif-pif-pif") gave quite clear clue there is high, combustion, pressure escaping into the exhaust. And that could obviously go only via a valve not sealing properly...
Exhaust will sound like that with any type of misfire 🙂
@@PineHollowAutoDiagnostics But the point is it won't sound that distinct sharp way. But by itself it may just suggest where to look further for true confirmation.
@@annaplojharova1400 it had a curious intermittent high pitched whistling sound however... Almost like a belt squeak. Sound disappeared after repairs. I think that may have been due to the burned valve!
Nah, on my 1940 Chev. truck 6 cyl. I had to get a head from the junkyard ($10), take it home and take out the valves, find some valves that weren't burned, I think from a 1941 head, grind them by hand, (12 valves) reinstall them, slap the head on with a new gasket, align the timing gear and adjust the valve lash (.08 to .015) then add water. 14 hours total time. Start her up and drive for 5 years. No oil filter and air cleaner was an oil bath with splash type cyl. lubrication. (Not a tall tale). I also spent 8 hours pounding out the left kingpin and replacing it, but that is another story. I hope my twin brother doesn't get mad because I left him out of the story.
Look forward to seeing you do the job
I'm doing one now and have seen plenty of them on the F engine
Question
On a 2001 Toyota Corolla, does the ECM monitor the door lock circuits and what voltage ís it on the switch side of the circuit? I had a compustar alarm installed but at times the system does not unlock the doors. I am thinking on how cartoys wired it up, the alarm system is sending 12 volts into a 5 volt reference circuit, not allowing the alarm system to unlock the doors at times. When it is doing it, with the doors closed, the power door lock switch is disabled on both front door switches just on unlock. However with the driver's door open, the lock switch will work. I know that the courtesy light switch is also used on the driver's door for the lock circuit. .
I am thinking of relaying the circuit on both look and unlock circuit to separate the alarm system from the cars electrical system.
I hate when that happens. You have no intentions of doing a job and next thing you know you are elbows deep into it. Happy fourth to you and your family. I always loved it when people asked me if we had the fourth of July in Germany. I told them sure since it doesn't go from the third to fifth.
I wonder if it is burning the exhaust valve from a lean condition when you leave off the throttle and use engine braking? That might be why is is only showing up in manual transmission vehicles. I haven't had to deal with one of them yet so I will be looking forward to the repair.
Tell us how he talked you into doing the repair!
A couple of thoughts without seeing part 2:
a) I don't think Subaru will cover it, they'll claim age and mileage
b) It would be cheaper to find an engine from a totaled car with about 60-70K miles on it.
I am a new driver and bought an old car from a local dealer. Now I found that this car has a gasket and wheel bearing issue. Is it worth fixing the head gasket and timing component in the 2010 Subaru Forester(150000 Kms)? or Trade?
I would check the head and cylinder for warping! Been there done that ! LoL
Have a happy 4th both of you!!! Awesome diagnosis on the button, cant wait for part 2!
You too Roxanne!
Nice and accurate diagnostics.
Wasn't a head gasket. You sure it's a Subaru?
This is why I charge buy the hour not buy the book. I work on American and Japanese cars only been doing it for over 55 years. Learned my lesson early on when you work on that many models hard to meet the book time. That would hard to do in 14 hours. I would also due both heads just to be safe. Doing one head may cause balance problems within the engine. Good Luck 👍
That was awesome Ivan
I'm not doing it !!!!!
Customer talked me into it lmao
I would have given it to you too,you are a good man
18 forester 6mt owner here. Zero oil consumption. Good power good mpg. I'll let you know when it turns into a lemon like you say
Please give an update after 100k miles 👍
@@PineHollowAutoDiagnostics wont be long
Yikes. Never saw a valve crack just like they, but have had a pizza slice taken out of one before I had on a Range Rover. And you got snookered into doing the job? Man Ivan, she must have been a looker! Hahahaha.
She tried the dealer and a specialized Subie shop... They just said "replace the engine" 🙄
Probably epic diag. I never see cracked valve. Amazing. And You’re really taking Subaru’s job??. Oh Ivan.I can’t wait! Looking forward to more episodes lol 😁.
You should look into doing training classes for your products. I would attend them at any cost. Great video.
Wonder if the manuals have programming that causes this or mis shift over revs or just unlucky valve material fault.
Mauals can just be operated differently to automatics. Like riding the idle governor in high gears, or running very low loads in high engine speeds - an auto wont let you do that. If the manufacturer then simply added a manual as an afterthought, problems can happen. Typically, a different gearbox requires new calibration of the control unit.
