The small plastic sleeves are to place on the keeper end of the valve. They slide over the keeper grooves to prevent damage to the seal when sliding the valve back through.
Rojasher25 so do you put the sleeve on the valve and push it through the seal when the seal is on the head already?
@@gabels540 don;t you just hate it when they dont reply?!
You can adjust the valve spring compressors by bending the inner part that makes contact with the crown keeper. I used a hammer to bend the (first valve spring compressor shown) so that it was closer together. I was able to compress on my EJ22 exhaust side with it, but not the intake side as it was too wide for it. But I am watching this to see if I did it right. lol. But that was to see how to install the new ones. I just used my thumb, and seems tight, but I have had anxieties like this before.
Dont listen to some of these people , you have done a great job with detail about what you feel is Important to
Know and the things you described in detail just so happened to be very important to me , I wish everybody was as considerate enough to make videos about the things they do that's not common sence
Nice job!
How did it go? Still burning oil?
Thanks again for this!
Happens alot, I'll had a socket that I was just using about 10 seconds within use and no where to be found. after couple hours of searching, ended up going to the store to buy new one. Later I found it was in my back pocket lol.
lol
GREAT JOB MAN!!! GG
you could have got some valve grinding compound and before you put in the new seals put some grinding paste on the seat of the valve and then used a medium speed drill and lapped a seat on to the valve and it's seating surface on the head that's what the turning the valve stem was all about you had seen I think. that would be a valve job then just hope your rings are good enough and not burnt any more oil maybe. you do have to clean off the grinding compound and then can inspect the seat on the head and valve both. I thing this is very necessary when putting in a new valve Unless you took it to a machine shop no problem its all done for you but cost good luck and thanks for sharing
I could have. But this was January of 2016. Engine is back together with 30k trouble free miles on it in the 4 years since this was posted.
Tha Little pieces of straw is for protecting the seal when you slide it over to Vavle
Where'd you buy the valve stem seals?
Got them in a head hasket/rebuild kit. Should be able to find them on Rock Auto.
should you put rebuilding lube on the valves when you install them after the seals are replaced?
Yes. But I didn't.
BluDog35 thanks. New engine builder here. Never done A Subaru motor, have one coming up on 250k miles on original motor and was considering doing it. Making sure there wasn't a difference between other vehicles and a Subaru when it comes to installing the valves. Really appreciate it!
Just build it like any other engine. It works the same. Just put together differently really. Follow all the manual says and don't do what I do. These videos I make are NOT how-to step by step videos unless it is stated.
BluDog35 well, thanks for the video all the same. The visual is enough to help me be a little more confident about it.
Cheers!
@@BluDog35 I really appreciate the video. You doing it with the knowledge and resources available to you then + me being able to read the constructive comments has really helped me out!
That’s a perfect way to lose a finger! You need the right tool for the Subaru valves. I would have modified that tool to fit right even if I don’t get to return it, rather than risking for a nasty injury.
good video, is it possible to remove valve spring without cam removal?
Yes, but you do have to remove the rockers. Cam removal is not necessary.
@@BluDog35 ,Thank you, my outback is consuming engine oil 1L every 2000KM, I am trying to replace valve stem seal without head removal,is it possible?
@@yijianggu5203 not really bud. Something like that should be done the right way.
@@BluDog35 ,My outback is consuming engine oil. I don't want to pull motor,just want to replace valve seals on position,is it accessible?
guy you dont have to pull the motor. You can remove the heads without pulling the motor
It shouldnt burn oil like you said, it looks like you did a thorough job, should be fine, but i suppose you would know by now haha
What happens when one of these seals go bad??
It really depends but it usually starts with blue smoke out of the exhaust. Which Is oil making it past the failed seal and burning in the combustion chamber.
You ramble on and on about things that someone who is talented enough to take off the cylinder heads of their vehicle are educated enough on how to use a tool by viewing you do it.
Zack Dowdle I'm not sure if that's a compliment or complaining about my rambling.
Someone who's educated enough on how to do this probably isn't going to watch this video. It's always best to explain what you're doing in an instructional video.
I didn't even know the difference between exhaust and intake valves before doing this, ha!
Can't you just use a socket like on all other valve springs
Sure you could to take the valves out. But you would use a hammer to compress the spring and knock the keepers out. Think about putting them back in. Using this tool on these heads makes it a whole lot easier.
I just took all mine out with a socket in hammer in about 2 maybe 3 minutes first Subaru head I've ever done I could see using the tool to put on but I just figured instead of spending all day taking them out with the tool just so you can say "I used the tool"
It's just the proper way to do it. Plus you risk damaging the mating surface of the head or something else using the hammer. These heads are aluminum. Soft metal. What's wrong with slowing down and getting it done right?
True but if you are talking doing it properly then use a feeler gauge when you do valve adjustment lmao
Burn!
only thing I see is your hand
Lmao wtf are you tryna do? First of all get the correct tool for the subaru springs
