got my new wrx motor installed and running last night, and started tweaking the computer to compensate for the increase in air flow... right as the motor gets to temp (fans had kicked on @ 186, and cooled the coolant down to 176) something comes loose @ idle, and before i can get to the key through the passenger window....

this cant be good....

That sucks! Better to happen now and not tomorrow on the canyon roads.

mongo not like!

OUCH!!!! That sucks.


Good practice though?

I did get to drive it... made it about a mile, said, ok, need to go tune, and came home, it broke in the garage....

Glad this year is over, hope next is better, will drop the motor tommorrow AM, go meet the driving crew for a picnic, and then spend the evening throwing snowballs @ Kim.

BJH

How about you fix the engine and I throw snow balls at Kim?????

Seriously bro,

I wish you the best of new years and a fixed engine.

Cheers,

Clayton

BJ, That is rough!

What would cause that, incorrect cam belt adjustment?

timing couldn't do that... unless i broke the head off a valve

I'm guessing foreign matter into the motor somehow, but wont know till it's tore apart.

BJH

CHOPSTICK!

it might be a chopstick....Motor was designed in Japan after all....

Damn sneaky bastards

BJH

Dude! That looks bad!

Wow, that sucks.

Better new year to you!

Ferg

Bummer....wanna come up and help me get the Turbo running?

you can't turbo a 914!

I had something similar happen to my 2.0 4 cyl 914 engine. It turned out to just be a crappy cheap spark plug that went back and cracked, but then the plug arched to the head and welded its self

Hey on another note how tough was it to drop in the suburu engine?

I think sumpin broke........

I B smart... I figured that all out by myself..

I wish i was there to help BJ.....

Let us know what transpires.

Clayton

All your pulley marks line up......timing belt slip?

Me sorry. Is it a JDM engine?

Is the Subaru engine an interference design (ie the valves will hit the pistons if the timing belt breaks and the cams go out of time)? It would suck to have to tear one of those down and haved to deal with all that water!

A lot of Subaru engines are not 'interference' engines.

Sorry to hear about it...

If I understand correctly


The valve should hit before the plug gets pounded...I wonder why a forien object took so long to make its way in ? I had alternator bearings fall into a cyl (don't ask) once. The results were bad fast. I would also check your fuel maps and timing at the time you were tuning. I doubt it caused the breakdown, but would realy suck if it happened again while tuning it.

Good luck Bro

Later

German car + Japanese engine can only lead to very bad Ju Ju. It's a curse. You need to find a Buddhist Priest to excorcise the demons within the machine or it will never run properly.

or have slits take a dump down the turbo....

Even off timing it never reaches the plug.
Something had to break at the conecting rod.

Broken wrist pin?

Damn dude!

I hope you get things ironed out. Knock on wood, the only problem I have is a small coolant leak. Mike J is gunna tackle that one for me in a few days...

Still need a new turbo though, do you got one?

Wilson

2, but if you're gonna replace it go bigger...

16G, bigger injectors, and back to crawford. good for 50 more HP at least...

Bring on the z06's!!!!

BJH

Well, since you're hanging out with the Uncharted Island Group, guess I'll have to post it here....

1.) BJ25 Short block

2.) EJ25 Long block

BJ: I see flares and wider tires in your future.

-Tony

Were either the shortblock or the longblock turbo originally? if not the compression is too high.

BJH

BJ...... that is a question I do not know. BJ25 pistons are flat top..... don't know if I can see the ones in the EJ25.

Any idea what they came out of?

I can find no info on a BJ25??

Intake lift doesn't need to be very high with boosted engines. Might take a little while for something to break the valves first.

After taking a bit of frustration time off, i have returned to this mess, dropped the motor this am, and this greeted me when i pulled the cam cover off....

One of these things is not like the others....

So off comes the intake, exhaust, and Head....

Anyone need an exhaust valve for an 03 WRX? Make you a GREAT deal on the parts i can find

Maybe you need a head (minus most of 1 exhaust valve)

ack! That doesn't look good. Time to buy yet another engine?

Last pic.... Good news is it didn't hurt the cyl walls, i have another factory piston, and a head....

Bummer.

I should be able to re-build this one, tear it down, quick pass w/ ball hone, and double check the cyls, new bearings, rings and good to go...I already have a Known good head, and 3 good spare pistons.

Have to go buy a 14MM Allen wrench to get the wrist pin out now....

i would take a good look at the rod and the crank b4 firing that thing up again.
get them checked cracks and for being bent. [betcha the rods bent!]

It let go @ idle, but i will check...

barf....

its the aircooled gods wrath!

making me run on 3 cyl to even things up??

Dayum BJ... you are havin luck with Subi engines like I have luck with 924s and 944s.

I think you've spent almost enough in subaru repairs as some have in /6 conversions. That's almost ironic, if it weren't so bad

PS, I'm looking for a good boat anchor, so if you got a spare junk block ...

I'm not into motors over 3K yet...

2K for the 1st one, 400 for the 2nd, gaskets, oil pump, waterpump, timing belt etc...

I dont see -6 motors running for 3K very often, and never over 300HP for that $
