Well, since Spence has neglected to be near a computer constantly.....

He has about 10 miles on the motor. Drove it home. NO smoke to speak of on startup. Some "knocking" noise.

Why does this matter?

I built the shortblock. 2002 RS case and crank, STI rods, CP pistons (I think), ACL bearings. Block was honed. Crank was polished (I think). Anyway, I was nervous about the start up. Always am....

Really happy about the lack of smoke. The knocking noise? Gonna either be the CPs or something in the heads (don't remember if they were hydraylic).

But super stoked for Spence!

Sorry about the delay in updating guys... just been busy and all.

and Doug basically got it covered!

It drives great, really smooth, idles well... some odd check engine light for Injector #1 but I know that its firing okay, well, because when you unplug it it starts missing lol... I'll hopefully get it sorted out tomorrow...

So this noise has me worried, its not getting worse, and Dave said it doesnt quite sound like a rod knock, but it doesnt go away once the motor is fully warmed up like piston slap from forged pistons normally does.

Here is a video of the noise, I know the quality of the actual video really sucks but the point is the audio, listen to it and please tell me what you think... Is it nothing to worry about or am I gonna have to tear it all apart again.

And Doug, no the heads are shim under bucket heads. You can hear the tick from those, but also the knocking noise.

And the vid was taken just after I got back from driving about 20 miles doing the ring break in routine that Doug told me to.

Sounds like my buddy's STi motor we built last fall...and yes, it has CP pistons too. It quieted down considerably after a few hundred miles, if that makes you feel a bit better.

Haha, thanks Zach

And here is a pic just before it was lowered into the car.

Hmmm that noise is kinda weird. Gonna be honest with you here, that's why my engine sounded like right before a rod bearing went out on me. Although, if you've driven it this long and it hasn't got worse, I wouldn't worry too much.

It must be piston slap. I can't think of anything else that would create a deep clanking noise like that.

wtf how though you just built the dam thing

asc_up · Post by **asc_up** » Thu Jul 02, 2009 8:26 am

Yeah, but how many miles have you put on it? Mine made that sound for about 30 miles and then it totally let loose.

smh0101 · Post by **smh0101** » Thu Jul 02, 2009 8:27 am

I've put probably about 30 miles on it...

What do you mean "let loose"?

SubaruNation · Post by **SubaruNation** » Thu Jul 02, 2009 8:28 am

OMG aaron wtf your gunna jinx shit!!

asc_up · Post by **asc_up** » Thu Jul 02, 2009 8:39 am

Oh shit. I swear I'm not trying to! I'm just letting you know what happened to me.

And by 'let loose' I mean that the entire bearing basically disintegrated and ceased to exist, thus causing an extremely loud knocking noise.

I'm basing this all off of the video. Maybe it sounds different in person. If Doug's heard it and doesn't necessarily think it's a problem, then I really wouldn't worry too much.

smh0101 · Post by **smh0101** » Thu Jul 02, 2009 8:43 am

Haha... Zachs just hyped up on caffeine I'm sure. So dont worry about him

Doug hasnt heard it yet, Dave has (old rallitek technician) and wasnt sure...

God I hope its not a rod knock...... (goes and prays)

Cuz I dont have the money to fix it, let alone the headgaskets, manifold gaskets, oil and all the other little things.

asc_up · Post by **asc_up** » Thu Jul 02, 2009 8:46 am

Haha I figured he was.

Either way, just be easy on it and wait to see what happens. It'll either get worse or get better lol.

Did you rebuild the bottom end when you did this engine build?

Doug did...

Its a 2.5L with CPs, STi Rods, and ACL Bearings

asc_up · Post by **asc_up** » Thu Jul 02, 2009 8:54 am

Haha well then don't worry about it. I'm sure he did everything correctly. He sure can build a motor.....and blow it. Lol JK Doug...well sort off.

But in all seriousness, if you had someone that reliable and knowledgeable rebuild the bottom end, then I'd point the finger at piston slap before a weak bottom end. Don't sweat it.

SLODRIVE even said that his buddy's STi made the same noise and it eventually went away, so just have hope!

In the meantime, drive it nicely and don't romp on it. Lol.

smh0101 · Post by **smh0101** » Thu Jul 02, 2009 8:58 am

Between knowing that Doug build the motor and what SLODRIVE said I'm praying thats the case!

Now had I built the bottom end I probably wouldnt be so optimistic!! lol

Overall I think I did pretty well on the motor!

asc_up · Post by **asc_up** » Thu Jul 02, 2009 9:01 am

I'd definitely say so! It looks awesome as hell. Are those the 25D heads? If so, how hard was it to get everything to mate up?

smh0101 · Post by **smh0101** » Thu Jul 02, 2009 9:09 am

Yep yep. 98 Legacy GT 25d heads

Bolted right up!

They came of Daves motor so he had already tapped oil lines in the head and for coolant lines I tapped into the Heater core lines. Seems to be working good so far.

And since they are Phase 1 DOHC heads the 20g manifold bolted right up... well... kinda... Since I used 2002 RS gaskets (the super thin metal headgaskets) the bolt holes on the manifold were a hair too far apart (since the ej25d has thicker gaskets).

For the PCV lines I used a conglomeration of WRX lines, ej251 lines and legacy turbo lines. Just played different combinations of things until it all fit! Worked just fine!

I still have to do some tidying up of the engine bay, you know, got lines running every which way, just to get it to run boost leak free. So I do need to spend some time working on tucking everything away nicely.

The biggest issue was the damned Coilpack. I couldnt get it to fit behind the powersteering pump because of the 20g IAC hardline that goes underneith the manifold.

And of course the exhaust bolted right up!

You wouldn't have happened to take detailed pics or have an inventory list, would you?

I'd love to add this to the DOHC installation thread.

Nice job so far. Good luck with the knock. Makes me jealous that my builder is dragging ass on my shortblock.

I'll see what I can do about figureing out which lines are which...

And just an update for everyone...

All seems to be well, went over to rallitek today and I noticed the knocking was almost gone, we could hear it a little when we revved it and Sean immediately said, "Oh, thats just forgies. CPs are known for being loud, nothing unusual there."

So that was a big releif!

smh0101 · Post by **smh0101** » Tue Jul 07, 2009 6:46 am

So right now I seriously just want to take a fucking baseball bat to my car. I have NO idea WHAT THE FUCK IS WRONG WITH IT!!!!

Well, not quite true... I'm guessing its a really ridiculously bad vacuum leak. that I can find... GRRR

I'm driving through battle ground and its bucking and popping and just not driving well. It wouldnt hold 50 miles an hour in 5th gear. what the fuck????

And even better... I have to be in court at 9:00 AM tomorrow 50 miles away for a stupid speeding ticket in the lovely fucking state or Oregon.

GAAHHHHHHHHHHH FML

So when I started it was sounding ok so I drove it to Beaverton and as I'm coming over the 405 bridge I notice lots of smoke. Well I made it to my appearance surrounded by a constant cloud of blue smoke... I was right by Dales shop so I stopped in for a sec to see what he had to say, well he said it was a PCV thing... wrong... what he told me to do made it worse. So I know what he said wasnt right...

I decided to limp it home and work on it there...

It died on me coming off 26 onto 405. It just wouldnt start. So my dad came and towed me with a tow strap out to Daves. Fun fun fun. that is one seriously stressful drive.

By then it started and I got it into the garage and on the lift. Pulled the turbo (because its been making a weird noise, even at idle...

And the exhaust is coated in oil, just covered, the inside of the turbo exhaust housing is completely drenched... but the turbo wheel isnt.... odd. I figured the wheel would be covered in oil if the seals where blown...

So I have no clue what the problem is as of now... IDK if its the turbo, IDK if its something in the block, or the heads...

I couldnt find a compression tester so I'll have to test that tomorrow with mine.

As for any CELs, only injector number one, but thats been there since we started the car up the first time... So I know that isnt causing all of this...

And btw, this motor hasnt even seen more than 6lbs of boost yet and has about 300 miles.
