My Little Engine Mishap (Pics Inside)

[apkarian100]

So my cogged pulley for my timing belt decided to freeze up Saturday and shear off the bolt head. It then proceeded to break through my timing belt cover and get stuck, melting into my radiator fan shroud. I will be trying to fix my car Thursday to have it running to get to the photoshoot meet on Sunday.

Wow! :palm:

[novacivic]

hate to say it but you may have bent valves

[02bugeyeoutback]

sorry to hear, good luck on the fix:up:

[bigd_wright]

Wow def probly bent some valves...that sucks....good luck with the fix:up:

[apkarian100]

I think 5 people have told me this. I turned the cam gears with a wrench and didn't feel any rubbing. I'm doing a compression and leak down test Thursday to determine bent valves and other such mishaps.

hate to say it but you may have bent valves

[04Wagoon]

I dont know anything about timing belts. Why would the valves bend? Im curious because I have 118k on my stock belt and Im trying to find the time to change it out...I'd rather this didnt happen before i get the chance, but if it did..what am i in for?

[squeethebee]

valves would bend if the belt snaps cause it keeps the pistons and valves moving in sync so the DON'T touch, because at different times they share a common space.

Get on that belt man, they recommend doing them at 105k I think.

[squeethebee]

Oh, and if it snaps on you, either a complete rebuild of your heads, or buying used heads, pulling the motor and buying headgaskets and all other assorted gaskets you will need, new fluids, AND all the stuff you would have had to do anyways if it didn't pop.

Do timing belt, tensioner, idler pulleys, water pump and maybe even an oil pump.

Sorry for the threadjack chris!

best of luck man, keep us updated :up:

how many miles were on the motor??

from what i've read the rs does have an interface motor so yes the valves will more than likely need to be replaced. If you want this number 742-2000 and ask for steve. He could tell you what the job would run and he's in somersworth. Heads up stems run about 20 a peice and you'll probably need all 16 and there's a lot of labor involved

[Evoeater]

His valves may not be bent..the heads seem fine even when the block is at TDC. I know Mike from Tuning Alliance had his timing belt break 3 times on his WRX and his valves never bent..so it all comes down to luck.He is already setup with my machinist to build his spare heads and the EJ257 block that he bought off me. He got a great deal with machine work. We will find out on thurs when I put everything back together for him and do a compression test ;) Then onto me fabing up that rotated kit for ya bud!! :D

[Seoul4korea]

ewwww I hope it's ok/

[98Wagoon]

hope its good to go, chris. Im not sure what Id have done in your situation

[apkarian100]

138kbest of luck man, keep us updated :up:

[boxer3maine]

time for an 11mm oil pump?
:dunno:

On the oldest subes, I found two holes two drill by the exhaust manifold, I am pondering what the rs has. the sprockets down low, why is heat hanging on that intensely?

given maine and its ethanolism, there is still a means to conquer beyond the average crap.

Look at it as not just a freak occurrence, but to find things to enhance around it. That will work for every car for a looong time.:)

[Berge56]

wow, good luck with the heads meng!

[apkarian100]

All parts have been ordered for the fix, most have been retrieved. :)

[SicRedGt]

It is a crap shoot if you touched any valves. Those damn idler and cog pulleys are cheap as hell. I recomend to change all the idlers and the cog pulley EVERY timing belt change. Subaru uses some cheap bearings in those things. My 83,000 mile motor is apart and you should feel how gritty/rough those pulleys are when they spin.

[Evoeater]

He was quoted almost 400 bucks for all the new idlers and cog gears by manch subaru..def not cheap

[apkarian100]

So the cogged pulley that came off was attached to the water pump via a bolt. The bolt head popped off and bent the bolt. Rather than try to wrestle the bolt out, I went and bought a new water pump, being as mine has 138k on it. I also bought a new thermostat and cogged pulley. I hand spun all the other pulleys and they spin pretty freely, so I won't replace those. The car will be reassembled tomorrow and then I can find out if I have more issues. (Cross fingers for the best)

[98Wagoon]

good luck, chris. hope to hear that its all good!

[squeethebee]

He was quoted almost 400 bucks for all the new idlers and cog gears by manch subaru..def not cheap

:eek: I got all of them, with an STI oil pump and a new water pump for 500. They are like $60 a piece.

[shtbxr22]

shoulda got a forward facing (turbo) water pump. then you could have bought the turbo manifold from me and.....yeah baby!

[apkarian100]

The cogged pulley itself was pretty expensive, near $80. The $400 price quote was including the timing belt tensioner, which was by itself $150.:eek: I got all of them, with an STI oil pump and a new water pump for 500. They are like $60 a piece.

[apkarian100]

What are you saying? I can't run a WRX exhaust manifold without a forward facing water pump?shoulda got a forward facing (turbo) water pump. then you could have bought the turbo manifold from me and.....yeah baby!

[shtbxr22]

Either turbo water pump, or 06+ 2.5i water pump.

[apkarian100]

Okay, so, yah, I have bent valves. 3 of 4 cylinders read 0 compression. So now I'm rebuilding the heads a little with some upgraded valves and new cams. :)

Parts:
-Delta 1500 SOHC cam grind
-Delta stainless steel nitrated valves

I started on the engine tear-down today with help of Evoeater.

excellent choice of parts! hope to see it running again.

sorry to hear about that man

[squeethebee]

Really? I know my tensioner without pulley (96 2.2) was $150, I thought my WRX style one was cheaper. Oh well, good luck man, hopefully you have her back soon.

[Berge56]

That sucks meng! At least you are getting upgraded parts and it will be better then before. :)

[987687]

I believe I told you this a while ago on IM and that it isn't a big deal if you break that bolt off :)

Glad it's all coming back together.
oh, and ps. I remembered that I'm on this forum now so I found your car thread :)

[apkarian100]

A little flair for my head rebuild. They are painted gun metal, but the pic doesn't give it justice.

[bratman18]

Man, it would have made things so much easier for you to pull the motor!!! But glad to see it's goin back together!!! You still turboing it?

[apkarian100]

It wasn't too bad getting the heads off the motor in the car.

....And yes, I'll still be turboing the car. Turboing will be done before wicked big meet.Man, it would have made things so much easier for you to pull the motor!!! But glad to see it's goin back together!!! You still turboing it?

Nice!!

When is WBM? I really want to go. I could drive the GL down to your house to exchange some wheelin' for a place to crash :D

So my heads are ready to pick up from Sanel's machine shop today. :)

I'm shooting to reassemble the heads tomorrow and put them back on the car, to get everything running, for Friday. :spin:

[shtbxr22]

picked up? assembling?

[apkarian100]

Got the heads reassembled today! Woo! Shooting to get the car running tomorrow. Some pics:

looking good. If you are looking for any more parts let me know.

[apkarian100]

Will do.looking good. If you are looking for any more parts let me know.

[apkarian100]

Well the car turned over nice and it was running great, but I had oil spewing out of weird areas. A little investigation and I figure out that I put ob the headgasket reversed, blocking an oil passage way to the heads. I'm pretty mad at myself for this. So looks like I'm just going to give myself a breather for a week and take apart and reassemble things after that.

This sucks...

[98Wagoon]

thats fu**in harsh. BUT, good side is you know you can do it, now. and you know the engines happy. so when you take care of that little.. uh.. issue... the car will be even happier with you! keep up the good work, chris!

[987687]

Been there, done that! Sucks man! Sorry to hear :(
A friend and I installed one backwards late one night. Such a sinking feeling ... :(

Now you know how to do it though! Shouldn't take you long to correct it :)

And, you probably know. But you can't re-use your gaskets. You need new ones :(

[bratman18]

That sucks man!!! Don't feel bad, it's been done many times before. At least you know it runs!!!!

[apkarian100]

At least the gaskets aren't too expensive.Been there, done that! Sucks man! Sorry to hear :(

[Demetry]

hopefully its all good come late next week Chris. It was definitely a little interesting yesterday though. That cat liter picked up about 8 qts of oil no problem, lol. I left an extra bag just in case, hopefully we wont need it...

[apkarian100]

Car is up and running again! Everything is working fine, no CELs, pretty smooth idle for a 1500 Delta grind. Nice power improvement.

[squeethebee]

Good to hear!!

now your all set for wbm

[apkarian100]

Indeed. That was one of the big motivations for me to finish it.now your all set for wbm

[98Wagoon]

cant wait to see the car up and alive again. the 1500 is noticeable enough? thats what Im thinking of running in the 2.0..

[apkarian100]

I notice it better than any mod I've done so far. It definitely opened up the power band. The idle is still decently smooth, not rough like I hear the 2000 grind is.cant wait to see the car up and alive again. the 1500 is noticeable enough? thats what Im thinking of running in the 2.0..

[98Wagoon]

awesome. I'll have to check it out one of these days.

[apkarian100]

If you go through with it and need a hand installing them, lemme know.

[98Wagoon]

sounds good! Im picking the engine and all its bits up this weekend. cams are already out. jake said he'd reinstall them too. we'll see when I get them back which way would be easier
