Default cam break in valve lash

After reading the factory service manual. Subaru recogmends adjusting valve lash after 100 miles to allow for cam break in. I definatly hear slight valve ticking the entire time I've owned the car . 25k

Anyone else subscribe to the subaru recogmendation of adjusting valve lash after cam break in?

It's certainly a better option than leaving the clearances loose to the point of ticking away. Go in and reset them.

subaru does not do an engine break in and re adj lash before delivering the vehicle to the dealer? they expect customers to come in after a couple hundred miles for an adj? i havnt heard an EJ that doesnt sound like a sewing machine.

well thats what im asking i guess . do they ? cause like you said ej's sound like sewing machines lol.

their service manual calls for it. but do they do it origionally?? i mean its not like they break the engine in for you , so why would they break in the cams?

i doubt that they do but in saying that they may i dont have proof either way. i just know that the manual calls for valve lash adjustment after 100 miles cam break in.

have you ever done head work to your ej race face? just wondering if you ever had to adjust the lash to the stock rocker arms?

right on dude yea you work on things that fly yeah? ive only been on maybe 10 flights in my life and only in commercial passenger planes . 1 propellor commercial plane . but man thats the life. i really wanna pilot a plane one day.

thats so awesome in it self. you drive cars , but you pilot planes!

whatever back on topic . this site is so massive does anyone or anyone know someone that works at the subaru plant in gunma? just out of curiosity?

i mean if im hearing ticking its beacuse they need to be relashed.

or i may just drive it even harder now so the head blows and i can rebuild it sick.

thats pretty much what im holding out on driving the motor into the ground then building it strong strong.

but in saying that ill probably dive in there to relash the rockers , cause i dont want to spend money if the motor is working fine.

can the head work be done with the motor mounted in the engine bay ? or does it have to come out?

the manual says its got to come out, but the manual says alot of things.

I think you can leave it in, but it is harder and it almost takes as long as it would to pull it. I just bought cams and have been reading on it and a lot of people do cams and adjust the lash with the motor still in but say it is easier with it out. I'm not sure if I want to do it or if I will pay someone to do it yet, it's too cold to spend that much time in a garage.

I'd be doing it in my dad's garage, he's got more tools than me and a way bigger garage. He's got a pretty good setup, just no lift yet, maybe next year. It's heated with 2 extra large bays that are 15' by 30' each separated by a workshop with just about every tool. My little brother has an apartment above it and every time I go over there is a line of Subaru's that he is working on. If you weren't on the other side of the country I'm sure you could use it.

I would like to as well but I'm color blind

I think I get this noise too. I get it applying load in lower RPMs (2000-2500ish) but only then, and only with partial throttle. The same rev range full throttle, no ticking, full throttle everywhere else, no ticking. And I used to only hear it in fifth gear but I've heard it in other gears now as well.
