Clint Hightower this was awesome, you speak in such a clear voice
Clint Hightower hi sir where can I buy that tools please thank
Can you tell me right or left on the hydraulic balance and that's the what is it harmonic balance to take it off thank you
The marks on the exhaust cam on the front vs back are going to be after you put the bolt in it correct?
That you sir 6yrs on and still helping people, helped me on my 2tz I appreciate it ❤️
Yep, love helping people. Thank you for your encouraging comment.
" very clear" instructions of this procedure!!!!!!!!!!!!!!!!!!!!!!!!! and the video was great!!!!! thank you!!!!!
Sir I want to thank you this video has been beyond educational. I want to thank you for taking the time to calmly and simply explain what is going on. You have been an immense help to this project.
You. Are. My. Saving! The first part with the spring loaded gear was what I was searching for, over 4 hours.. Thank you sir!!
Thank you for the comment Richard, glad I could help. Happy new year!
Clint Hightower today, I have finished the installation of the camshafts on my sisters Cuore. As feedback: this video does also applies on that 3 cilinder EJ-VE engine. Camshaft lobe facing to the front of the verhicle (with engine at timing positions), timing marks on the gearlinkage and the springloaded gear with a set screw (Daihatsu is M5~8mm though). Again, many thanks and a happy and great newyear!! Hero
Sweet! That is awesome, thanks for the feedback.
Very very good instructional how-to-do-it video! Thank you so very much, dear, sir, for this fine help you are sharing and giving with us Toyota owners! Wishing immensely richly blessing from God and stay blessed! Best regards from Sweden!
Man i sure appreciate u and this video. Lol.. Im doing head work on this same engine. I thought it was a sohc to i took the valve cover off and it was a dohc. Man u save me. Lol. Greatly appreciate it..
So far the best explanation i have seen
Thank you.
Thank you :)
Finally a through explanation I really appreciate this maybe I can get the car to start now thanks buddy for taking the time, I knew the lobes needs to point somewhere specific

Hello Mr. Hightower. Can you do a video on replacing the camshaft seal on the 93-97 1.8 7afe engine. You seem to take the most time explaining things in detail. My 96 Corolla dx has 363k and still going strong. Thanks.
Clint, thanks for the video. It helps, as I am putting my 1994 Celica ST back together. At present time am trying to put a rebuilt head on its 7AFE engine block, but realized that the camshafts are in the way of the head bolt holes, so the camshafts have to come out first.
The manual instructions say that the service bolt screws in to the two gears (one is called a sub-gear) of the intake cam, and pulls them together to squash the spring inside, to remove as much thickness as possible so you don't mess up the head or cam material, breaking or scarring either one when pulling out. They say you MUST bring out and put in the camshafts holding them perfectly level.
I am having trouble getting the two gears lined up for the service screw to catch he threaded gear, and will try to buy that spanner you used, thanks. I hope it works.
Maybe it would be helpful to future readers if you posted the name of the tool, with a link to a source. Way down in the comments, I found you had posted a link. It now leads to an eBay error page.
Thanks for your comment Bill. The reason they say lift the camshafts out level is so you don't crack or break one. They are very brittle and when loosening their bolts loosen a little at a time so that the cams come up even, you don't want any stress on them or you can easily break one.
The name of the tool in the video is "Pin Pliers" I will put a link in the description to a set on Amazon.
@@Engineerboy100 Thank you, Clint. I can see you are a good man, and appreciate your helpfulness.
Hello again Clint. I received the tool you suggested, the "Pin Pliers." Now, I am using those pliers, to try to turn the sub-gear clockwise while holding a cresent wrench on the flats of the camshaft and putting my maximum force into the effort, but just cannot get the sub-gear to turn any, so cannot line up the hole to insert the bolt to pull the two gears together on the intake camshaft. The repair manual states that this bolt MUST be installed before attempting to remove the camshaft.
Remember, I am attempting to remove the camshafts from a re-manufactured head for my 7AFE engine, so the two cam sprockets (gears) are meshed and the camshafts are still bolted in with 4 caps each. Only the intake number 1 cap has been removed, nothing else. Given that assembly, should the sub-gear be able to turn the slight amount needed to line up the holes? Is it just that I am not applying enough torque? Maybe a bigger, stronger man could do it?
BTW: the 1994 Celica ST manual specifies the intake camshaft for this 7AFE requires a 6 mm 1.0 bolt of from 15 to 20 mm length. You said yours was a 10 mm bolt. The threaded gear is the thicker one, so I think I would have to screw the bolt from the other side than you showed in your video, i.e., the sub-gear side, to pull the two gears together so the shaft can be eased out. @@Engineerboy100
@@billcowhig5739 If the gears are still engaged, you don't need the tool, the hole is already lined up. You only need the tool if you take the cams out and forget to put the screw in before removing them.
Easy to understand instruction........
You are AWESOME 😎 thanks 👍🏻
Your information is the best, thankyou sir
Thank you so much Magnum, I'm always trying to improve. Hopefully my future videos will be even better.
Thank you!!
Thanksss boss's..this verry clear...to understand....
Informative and to the point
Love this video, thats for sharing, you are an excellant teacher, slow and precise for old timers like me:)
Thanks,really explained alot
Congratulations good instructions, thanks
Smart trick on tightening the tension with spring on so don’t have to fight with it later
What a great video

Very informative video
obrigado meu amigo estou montando um cabeçote agora você tirou minha duvida
Buena suerte y bueno para usted. Que te diviertas
I have a Nissan Micra 2005 cr14 engine. Can you assist with setting up the camshaft timing without removing the timig cover cover.
best teacher
Thank you :)
Enjoyed the way you explained this tricky procedure. Is the 5s-fe time up in a similar way? Cheers
I'm not sure about the 5afe. But the 4afe and 7afe are the same. I have done both.
This video has been extremely helpful. Thank you.
Question; On my 7AFE 1.8L with 140K turns out the Camshaft bolt backed out 1/2 in and the Knock Pin dropped out. I did find it. It must have slapped against the wheel groove widening it by a few mm. About 3to4mm of slap. So wil replace the Top Timing Wheel for sure. Do you think I would need to replace the Exhaust Cam as well? Im looking for a new knock pin but I believe it's sold with the Cam only.
There's no way for me to be able to know if the exhaust camshaft needs to be replaced or not. One rule of thumb I have found to be true with camshaft damage, they don't usually "bend" they are fairly hard and a little bit brittle. usually camshaft damage is they either crack or they don't.
Excellent video! Thanks for posting.
Great video Clint !!! enjoyed you explaining how to install !!!! Keep up the good work .. I just subscribed
Thanks Frank :)
how do you connect leads with the coils of a toyota corolla 4E engine
Very nice video
Thanks 43 :)
Thank you juses
Thank you so mush
You are welcome, I'm glad you liked it, more to come :)
hey sir thank you for all the explanations...but could you do me one favour...is the stock camshaft sprocket really adjustable...if it could can you show me how to adjust please...my car is very slow to gain speed even my timing engine is correct.
Yes, the sprocket is supposed to be sprung, see this video ruclips.net/video/VhGWPQTQDOU/видео.html
Does the two cam lobes is at same angle or the intake cam lobe will be facing higher / upper?
The lobes will not be exactly at the same angle but the lobe angle is only to be used as a reference. Go by the timing marks for the correct timing.
@@Engineerboy100 thank you I got it right. But I still have issue. Can I get your facebook account so I can message the video
@@Engineerboy100 I have a ticking sound and it seems near the intake manifold. I know injectors make some ticking noise but on what I am hearing it is a bit louder and it is coming near the intake manifold.
Thank you sir
You are welcome :)
Hola saludos buen video
With your set screw in place, how did you get the sub gear lined up with the main exhaust cam gear? trying to realign mine on my 2fzre 2.4L
you need a cam gear alignment tool, something like this: www.amazon.com/EWK-Universal-Camshaft-Sprocket-Holding/dp/B00VFPOF1E
I love your lessons
Is this cam shaft installation the same for the 4AGE Blacktop? At TDC, shouldn’t the cam lobes over No. 1 cylinder be pointing toward each other, not pointing towards the front of the car like what you have shown in this video?
I believe so. 7afe and 4age are very similar. I think the heads are the same but the bock displacement is 1.8 and 1.6 litre respactively
thank you
Midnight Raiin my pleasure, you are welcome, glad you liked it
Thanks
Thankx 4 the time.sir
Thank you, I love learning from others and sharing what I know.
Power full
If I don't have the bolt can I use a smaller bolt to fit through the holes ? Does it have to be threaded in ?
It's best to use the correct size bolt for the best results and the most accurate re-alignment of the split gear teeth.
How do I know if I’m 1 belt tooth forward or back, off?
When I align the camshaft holes with the camshaft pulley hole and crank to 0 my belt is in 1/2 tooth of the belt.
I’m not sure if I should move either the camshaft or crankshaft forwards or backwards to align with the belt tooth…
Any help appreciated thank you for the video as well!
You have to make sure the timing marks are aligned first, then you align the belt with the cam sprocket and the crank, not the other way around.
@@Engineerboy100 the dots on the cam were aligned and the crank was aligned at tdc, just it aligned at a half tooth so either I had to go a bit back or a bit forwards to fit the sprocket groove.
Ideally I think it’s on time now just the extra 1/2 - 1 second of starting. Before I’d turn the key and it would fire almost instantly, so I do believe either I’m off a bit or the parts are new and it’s tighter. I think more so I’m off a bit, first time doing a timing belt.
Miss that step of service bolt and now back assembling camshafts do I have to put the service bolt? Before assembly?
The service bolt is for holding the spring tension of the sprung sprocket so you can get the gears to mesh. If you assemble the engine without the spring tension of the cam gears, they will rattle quite noisily.
Clint Hightower thank you sir GOD BLESS YOU AND FAMILY
this is Good
Thank you Noah! :)
whats the torque setting for the cam bolt on the 3rz-fe my year truck is a 2000
Not sure, but I would never trust an answer to that kind of question over the internet. That is a look it up in the shop manual kind of question.
Good job! Only thing I would add it that a lot of corollas have two holes in the camshaft gear. Line the hole marked A, not the hole marked K
Good point. Thanks Mt Man :)
Hey I’m working on 2002 tundra 3.4 liter v6 5VZ. Been stuck for bout 4months . Trying figure out if I got cam gears set rite if the timing is rite . I’ve been watching your video over over . I’m not quite sure if my timing is rite . Oil pan is still off I could send picture video if it would help you to better understand .
I’m trying do same thing to the motor like your video same concept . I’m just thrown off by . Your corolla had two cam gears which in my case I have two sets . And that’s where I’m assuming Why I’m not able to understand clearly.
So just like to thank you . All your videos are useful easy to comprehend. Or I’m looking at this particular video and watching it in a wrong way?
You should get a shop manual for your exact model vehicle, and follow the procedure for setting the timing, each vehicle can be a little different.
Clint Hightower yeah I purchase one from advanced Haynes manual . I wanted to get the dealership manual price for the knowledge is reasonable n fair for the info it contains . Not able to afford it yet. But hey thank you . Least you took the time to reply with honest advice .
How can I remove the bottom timing belt sprocket? I tried prying a little with screw driver. Not much area to pry.
I was planning to replace the seal behind there.
You may need to use a puller.
Can you not just set everything to top dead center before taking the timing belt off? Then as long as you don’t move anything but everything back together as you found it including the camshafts because shouldn’t the cam shafts alignment marks be lined up perfectly whenever the engine is at top dead center?
Yes you can, but why would you want to? It make if very hard to double check to make sure the timing is correct. You could damage the engine and for what? too much risk for no reason.
I read somewhere if taking the cam shaft out with engine in tdc you could bend a valve when installing the cam back in again as when your tightening the bolts for the cam it compresses the valves and a valve could open which piston 1 could hit into if the valve was to open whilst tightening the cam down?
Was told it's best to set everything tdc and remove but when installing the cam back in you should rotate the crank 90 degree left or. Right so piston 1 isn't all the way up. Ones the cam is torqued back down then you can turn the crank back 90 degree and fit the rest of the car back together. It ensures no damage to valves etc. What do you Think to this theory?
Hi sir,i have a cuestion...the book for toyota four runner use the two points dot marks to do the head gasket replacement.what to do if the dot marks are aligned but the little hole of the cams is like 5 o clock instead at twelve o clock. I hope you understand my broken English.
Just in case you answer my cuestion my car is a 4 runner 99
It means you are probably 180 degrees out of time. You are trying to time the engine on the exhaust stroke and it needs to be on the compression stroke. Turn the engine over one more time manually, by hand and try it again and the marks should align. and yes your English is fine.
Thanks for replied.im doing a head gasket job, the timing belt is not in place,it's posible to rotate the camshaft using the bolt and rotating it to the right? Or it's better to dissamble and start over again.
Is this the same for the 1999 Camry 2.2
No, two different engines.
after rebuild setting camshafts and timing as it should be I got a ticking sound in the head of the engine, you know what could be my problem?
Yes. That ticking sound is your lifters. Toyota's have solid lifters and can only be adjusted by replacing shims. the thickness of the shims establish the distance of clearance between the camshaft lobes and the lifter "discs" there are specs the manual and you have to measure the clearance with a feeler guage ... it is not a beginner project .... read up on this more before attempting.
TurboFo_Oil_Changer Porsche_Light_Saver thx for quick reply, you know where I could find the manual online as I bought the car and the previous owner did not have the manual

Me is a mechanic I like this thing
i have a 1mzfe am putting back together. the spring gear is what im confused about. the 1mzfe doesnt have a set screw, so where should the spring gear line up? I can make it so you can partially see through the hole or i can turn it some and make it so i cant.
I'm not sure what the thread pitch is on the 1MZFE, but a common bolt is the typical 10mm, test the threads with a few bolts to figure out what the thread pitch is or you can cheat and look in the shop manual for your camry or whatever your 1MZFE is in and it should tell you. or you could call the dealer and ask, sometimes they are helpful.
Thanks for the quick response! i have both heads off and both dont have set screws on either of the the given cams. So you are saying its suppose to have set scerws there? not sure if im the first one to rebuild this but it was running fine without the set screws whole time ive had the vehicle.
i just looked at it this am. the cam with the spring gear can be moved to 3 diffent teeth, if that makes sense. probably the middle one is the right one?
Does this work for 5afe engine also? And does the hole on the sprocket have to be in line with the lobes facing the front of the car?
I'm not sure about 5afe but it works for 7afe and 4afe. check out this page, it might help. motor-car.net/toyota-engines/item/14611-toyota-5a-engine
@@Engineerboy100 i guess it does
The engines are similar
Hi there what is the name of that tool and where can I purchase it? Please let me know thanks
It is a pin spanner wrench, there are many configurations. Hope this helps.
Hi Clint my intake cam has no set bolt
just get a small 10 mm bolt, it is a standard size not sure of the thread pitch.
Hello. I'm wondering if this engine uses a camshaft sensor. If yes, Where is located?? Thanks
The 1994 doesn't have a separate CPS, only OBD2 (95.5-96+) 4afe/7afe have a crank position sensor for determining cylinder misfire. It's part of OBD2 emissions self diagnostics. 94's rely on a cam position sensor that is inside the distributor.
Clint Hightower .. "Thank you Sir".... Useful information....
I replace my Toyota corolla 1.6 2000 model cylinder head gasket, set timing and everything but the engine crank but don't start. I replace ignition coil, spark plug wires.
Check timing and fuel pressure.
Chek spring loded camshaft and timing
This can also be applied to the 4aFe?
Yes, the head is the same, the 4afe only has a different size engine block, 1.6 vs 1.8. I have swapped heads between them.
How much force does it take to re-spring the scissor gear?
Very little like 20 fb-lbs ;)
Clint Hightower I just replaced the cylinder head on my tacoma 3rz and could not figure out why it was making noise at idle and also slightly misfiring. I guess the backlash was just enough for a slight misfire, Thanks to your video it runs 100% now thanks a ton happy new year ✨
Is this the same for a 4EFE engine
No, they are not the same. there are similarities, but they are definitely not the same.
in form sudan i say vary thank you
Hello. Can this go for a Toyota Prado petrol?
I do not know, but I don't think so, each car is usually different. Sorry.
Bueno Días maestro me puede decir cuál es el número de la retenedora del eje de leva
No lo sé, lo siento mucho.
Does the timing affect the vehicle's power?
Yes! The timing is everything in an engine.
great one nice
What's the torqued of the camshaft?
You should get all of your torque spec . information from your shop manual, never trust someone telling a torque value on an importing internal engine component. If that is how you get your torque information, you should not be building engines.
Is this timing the same for celica sti?
Not sure about the sti, but this engine did come out of a Celica.
@@Engineerboy100 thank you

Why cam shafts make louder when engine are on
Lifters need to be shim adjusted.
is this the same with 4af engine?
Yes, Same as 5afe,.
