Yes Bill, I Agree Absolutely about that this Setup has Disabled the Burning of Harmful Engine Gases, You`re Right; I Just Forgot to Say that I Just Want to Avoid more Oil for Comin` to the Carb While the Problem of my Subie is Completely Fixed, so That is some sort of Temporary Setup... Not Permanent.

Then, if I Solve the Problem, I will Put a "T" Between the PCV Valve and the Air Filter Box, to allow a Connection Point for the Heads` Hoses.

But instead of just attach there the Opening from the Head`s Hoses "T" with just a Straight 5/8 Hose like it was Before, I Plan to install Between the Heads` Hoses "T" and the PCV-to-Air Filter Box`s Planned "T", an Special Oil Catching Bottle, in order to Avoid Oil from Goin` to the Intake; Just the Said Harmful Gases. What do you Think About that Idea?

Thank you,
Kind Regards.

HOLY COW!


Today I Found what I Believe could be the Cause of my Subie`s Problems: One of the Timin` Belts -the one at the Driver`s Side, Nearby the Disty- has Three Missing Teeth! ... :eek: ... at Different Belt`s Places, also another One is about to Fall off...

What do you Think About that? ... I`ll Post Pics as Soon as I Can.
(I taked Pics but I Don`t have a Computer for Now, I am using a Neighbour`s one that I Borrow for just Moments)

I Work in my Subie, just the Tiny Spare Time that Remain after my Job and to be with my Family... That is Why to Discover that Took too much Time for me... Just a Little Step every Day`s Night... :-\ ...

Kind Regards.

No, I Run it With Covers On; Always.

Those Pictures that you Saw, are the Actual Look of my Subie`s Engine, Because I am Workin` on it Now, Tryin` to Fix it.

This is how it Usually Looks:

I Don`t Like the Idea of Run the engine with the Timin` Belts Uncovered, `cos They are Fragile and I Don`t want that -for Example- a Li`l Gravel Rock or a Flyin` Plastic Bag or Something alike, could Damage `em and even make the Engine to Stop, leavin` me in the Middle of Nowhere...

But some people Does Run theirs Uncovered without issues... So Far Maybe, I Don`t Know; but I Do Preffer Covers on.

The Only advantage about Drivin` it Uncovered is that the Timin` Belts Job would be Very Faster and Easier to Do.

Kind Regards.

Today was a Non-Stop Rainin` Day, it didn`t let me do Anything on my Subie... I Hope that Tomorrow I`ll have a Chance.

I`m Tired of Goin` on Bus to my Job... :-\ ...

Does anybody had that "Missin` Teeth" Timin` Belt issue?

I`ll Like to Know if their Subies got that Same Behaviour...

i've had something similar but on a different car. big ol section where the teeth came off, more than one more like 10 or 20.
was in a Maxima (U11 body VG30E motor) wasnt so hot. 8 bent valves and some minor head work, still cost about $2k because i didnt have the time nor the tools to do it my self. i guess it was kind lucky i was saving up for a computer setup and some stocks but ever since then money has been hella tight and i dont know why.

any way atleast this isnt an interference motor so thats cool.

the werid part about it was i was doing burnouts before i left work, worked at a lube shop, we would smoke out the car wash guys....any way it had no problems but come up to a stop light and go when it turns green like normal and rattle rattle rattle.....quiet.....hmm no steering

Absolutely Yes!


My Country have been "Shaking" with minor EarthQuake`s Replicas... that along Non-Stopin` Rains, didn`t let me Work on my Subie earlier.


But the Last Weekend I Worked on my Subie with Great Results!!!


First after a Deep Clean up the Engine, I Started to set the Correct Ignition Timing, before install the New Timin` Belts, Tensioneers and Covers. (The Old Covers were Worn and in very Bad Shape after 24 Years and over 270K Miles of use so Far since 1985)



This is a Picture of some Parts of my Subie`s New Timin` Kit:


Posted Image



I Noticed that the Recent New Subaru Parts Comes in Plain White Boxes, while the Old Times New Parts came in Blue & White Printed with the Subaru Logo Boxes... Well, the economy... but That Doesn`t matter.

Even some Parts came Without a Box!

Well, I Started from Square One: First I did Set the "Upper Dead Point" (I Don`t Know the Right Translation for That, But I Hope that You`ll Understand) in Cyl one, then all across the Engine... I Noticed that my Subie`s engine Timin` was Very Bad, to the Point that I Needed to Take Off the Disty and Reset the Timing Again.


After That, I did Set all the Timing Again, with the Only Help of the Great MilesFox Timin` Belts Procedure Manual, as Seen on the USRM; Thank you, MilesFox! :)


Then I Installed the New Timin` Belts + Tensioneers & Covers, also Replaced the Worn 5/8" Hose at 90º (that was the Cause of the Water / Coolant Leak) along with New Clamps...


I Really Dislike that Hose`s Place Design... but it Could be Worse: Recently I Helped someone to Change the Sparkplugs on his Mitsubishi Eclipse V6... Oh my God! ... You need to take off the Intake to do That! ... :eek: ... Now I Love even More my Subie`s Engine Design...

Excuse me for the Short Posts, I Still Don`t have a Computer, mine is Damaged and this one -From a Neighbour- Trend to Shut itself Off in the Middle of the Use, due to OverHeatin` Problems.

I Noticed that my Subie`s Engine Behaviour have Changed since that Timin` Belt Job: Now the Engine Runs Smoother than Ever, but it Also have a Different -Quieter- Sound, Let me Explain:

Since the Weber Swap some Years Ago, my Subie`s Engine Sound became Very Louder, Specially when the Secondary was Open (Full Throttle) and it Was Very Fast to Accelerate from Low RPM`s engaged -for Example- in Second or Third Gear, but it was a Little "Slow" to Gain Speed at Higher RPM`s while at Full Throttle.

Now the Engine Sound is Very Quiet, even at Full Throttle ... :confused: ... and Also my Subie has the Opposite Accelerating Behaviour: it Slowly Gain Speed at Low RPM`s but if the Car is Runnin -For Example in Fourth Gear- and around 65 MPH, if I give it Full Throttle, it Accelerates Super Faster from 65 MPH to around 100 MPH (I Had to Slow Down `cos it is Pretty Scary in our Crazy & Bad Roads to Run very Fast) So it now Likes Higher RPM`s, but the Loud Full Throttle Sound is Almost Gone in exchange for a More Deep and Clear Boxer Sound.

Even it Sounds Just like a Hair Dryer at Low Speeds / Low to Mid RPM`s ... :eek: ...

Anybody can Tell me Why it Has This Behaviour?

I Believe that Maybe my Last Timin` Belt Job, the one done Bedore this new one, wasn`t all Right after all...

Also the Subie Feels more Powerfull, I Tested it in a Highway that have Many Uphill and Downhill parts: Before the Timin` Belt Job, my Subie was Doin` one Uphill in Fourth Gear at 2,100 RPM`s without Gain more Speed, Now it Reaches the Same Point at 2,300 RPM`s and it Gain Speed during the Hill`s Climb, up to 2,600 RPM`s...


As Aditional info: I ReJetted the Weber Carb with a Bigger Secondary Jet, as you can see Here:


Posted Image


Could it have something to Do with the Increased Performance / Reduced Engine Noise?

Well, I Miss my Weber`s Roar...
Kind Regards.

so basicly your saying your car is running quieter and in the lower RPMs it takes a while to accelerate and then at a certian point it just takes off?

mine does that, i dont know if its normal though. just letting you know your not the only one

Yes, That is the Behaviour, but my Subie Feels More Powerful than Before...

Is your Subie Carbed? ... if So, it Still have the Hitachi Carb? ... Those have a Vacuum Operated Secondary that Maybe is Improper Plugged Causing that "Delay" in your Subie.

Kind Regards.

Congratulations!!!!!


And as for the retuned carb, it may not be the carb, it may be your timing.
Let me explain (even though I'll probably get most of it wrong), as far as I
know, if you advance your timing it will give you more upper end torque and
therefore more acceleration at higher RPM's.
If you delay(?) the timing, I believe it gives you more power down low, but I'm
not sure, I have yet to do any testing on this.

So your disty may have been incorrectly timed on the last tune up and now
that it is properly timed, you get more power! :banana:

Oh, and if its ok with you, I say we should petition the mods to put this
banana as an emoticon Posted Image
And so it has company :banana::banana::banana:

You may have gone too large with that secondary jet - it sounds like it's having trouble at part throttle on the secondary side. You may be flooding it when the secondary first starts to open.

What jets were in it before and what is in it now? I can tell you what may be happening better if I know what jets you are running.

I think you are getting a lot of power at wide-open-throttle because the air-bleed is leaning it out just enough to counter the super-rich secondary main jet - it's still rich but it should be pretty rich at wide-open-throttle anyway.

Well... Since the Timin` Belt Job, the Engine Problems are Gone, Thanks God!

But About the Jettings, The Original Hitachi Carb that came Stock on my Subie (Mine is 1985 California -Yes, USA- Version) came Jetted as Follows: 116 in Low Stage and 160 in High Stage, for a Total at Full Throttle of 276.

My New Weber Came in the K-731 Kit Already Jetted for the EA82 at 140 in Low and 140 in High :confused: interesting, the Total at Full Throttle is 280, Very Near to the Stock Hitachi`s 276.

Since I Swapped the Weber Carb in my Subie, I Noticed that the Lower Range RPM`s got increased Torque, but the High Range RPM`s Behaviour seems to be Almost Equal to the Stock Hitachi`s, Same Feeling.

So, Thinking about the Increased Air Bleeding Capabilities & Size of the Weber Carb, also thinking about the 140 / 140 Jets and the "Feeling" it Gave in Both Stages, I Realized that Maybe those People at Redline-Weber Sets their Carbs for Applications at the Average Use, Because the Grand Total of 280 is Very Near to the Hitachi Stock 176, even if the Weber is Really Bigger...

...What jets were in it before and what is in it now? ...


So I Tried with Many Different Jettings & Test Drive in Many Different Situations, in Order to Get the Best Performance Without Getting the Mixture too Rich or Flooding, nor letting my Subie to Swallow more Gas unnessesary...

After All that Weekend`s Tests, I Leaved the Weber`s Low Stage as it Came: 140 without Modifications; and the Best Performance at the High Stage was Gained with 172.

So Now my Subie has Exactly the Same "Great Improvement" Feeling from the Low Stage, in the High Stage Too! ... Let me Explain my Subie`s Behaviour:

There is No Black Cloud Comin` from the Exhaust, There is Absolutely No Flooding Too, the Throttle now Seems like if it Virtually Gained Two more Inches Down the Floor! :eek: Also the Acceleration while engaged in Third Gear or Four Gear, Really Increases when I Press the Gas Pedal Fully and the Wonderful thing is that my Subie Now Reaches to the Top of the Large & High Hills in High Gears at Higher RPM`s than Before the Jetting Swap.

Before I Changed the High Stage`s Jet from 140 to 172, my Subie was Loosing Power during those High Hill Climbs and suddenly needed to Shift Down Gears... Now the Change is Amazing, it Just Sounds like a Locomotive that Keeps its RPM`s all the Hill Up! ... :headbang:... Not Gaining more Speed but NOT LOOSING IT Like it was Before.

But the High Noise on Fully Throttle on my Subie Became Quieter & Smoother than before... Weird, isn`t it?

I Hope that I Can explain the Situation Clearly: Seems like it Gained a Li`l bit more Hp and torque at High RPM`s Range ... Seems like the Weber`s Air Bleedings already came set to Handle the increased amount of Mixture very Well... but if I Drive with Full Pressed Gas Pedal it will Use a Li`l Bit more Gas than Before, but Believe me: it is Almost unnoticeable and giving a such Small engine more Power, really Worth it.

Background information: I Needed to Move the Disty in Order to Reach the Better Timing Point to Make my Subie Work like That...

The Only Few Moments when I Feel a Li`l bit of Flooding, are when the Subie is First Started Cool early Morning and Only if I Press the Gas Pedal too Deep... but my Weber Carb Does Not have Choke at All, also that Behaviour shows only for the Very First Minute or Two after Startin` the Engine, then Dissapear.

I Have Followed my Subie when my Wife Droves it and I am Driving my Job`s Car Behind, and I Never seen Black -nor any Colour- Smoke Comin` from the Exhaust Pipe, even when it is Climbing a Hill... Just a Li`l Bit when she Shifts Up the Gears at High RPM`s

One Last experience: My Subie`s Sparkplugs comes in Light Reddish Colour, they`re Not Blackening Anymore. :)

I Hope this Will Help.

Kind Regards.

Oh my Goodness!!! ... :eek: ... No Edit Button after a Month! :banghead:

I Made a Mistake when I Wrote the Amount of the New increased size of the Secondary Jet, the New Size is 162 not 172, it was a Brainfart... so please Excuse me.

My Weberized Subie Runs on 140 Jet on First Stage and 162 Jet on Secondary Stage.
