View Full Version : I spun my Rod bearings how much should this job cost?
pololla 09-20-2004, 12:54 PM I accidently went from 6th geat to 3rd gear instead of 5th last week at high speeds and my rev limiter bounced like crazyyyy and now I my rod bearings are done.. thank g-d I didn't blow my motor. Anyways The shop called me to tell me that my bearings are shot and now tehy need to machine the crank . I don't want to get rapped here does anyone know how long a job like this should take? It's a 2004 STi.. he said 15-20 hours of labour .
TKDKracker007 09-20-2004, 01:08 PM Didn't notice any resistance from the gearbox going into 3rd?! Shoulda jammed that clutch in as soon as the revs climbed to redline bro.
Ouch though, thats a baaddd day. Thats a bunch of labor, doesn't sound far off to me, considering that the crank needs machined and all new rod-bearings. That motor saw some serious rev-limiter action.
thesmokingman 09-20-2004, 01:15 PM At 15-20hrs of labor @ $60, $60 is a lowside typical rate it comes to $900. Does this include assembly, etc? Hell for $1300 you could get a whole new shortblock. I'd just get a whole new block if I were you.
Beaverboy 09-20-2004, 01:17 PM When you mis-shift and drop the clutch, the rev-limiter has nothing to do with it. When the wheels are pushing the engine past the fuel cutoff, there's not a thing the engine management can do to save it.
I'm only mentioning this because there are lots of people who are afraid of hitting the rev-limiter because they think it causes this kind of thing. The rev-limiter had nothing to do with this.
A spun bearing from over-revving is a blown engine in my book.
Lets see, they'll have to remove the engine, open it up, remove the crank, have it machined, rebuild the engine (all the normal rebuild labor) and put it back in your car. 15-20 hours sounds good to me.
jesse370 09-20-2004, 01:20 PM buy a new short block man....
Uncle Scotty 09-20-2004, 01:21 PM Get a new short block and be done with the old one....I'd bet your 'shop' either knows they are relativlely cheap and will try to charge you for unnecessary labor or doesn't know that they are available.....get a new shortblock either way.
pololla 09-20-2004, 01:33 PM Were the hell doI get a new sti motor ?
pololla 09-20-2004, 01:49 PM I have ECUTEK.. will als this engine work reflash this? I hope not.
jesse370 09-20-2004, 02:47 PM No the ecutek is part of the computer. All you are doing is taking one usdm sti short block and swapping it for another one.
DISCOPOPE 09-20-2004, 02:52 PM get in line for a built block, and take the bus till it ships...
kidatari 09-20-2004, 02:53 PM www.subaruwrxparts.com has STI short blocks. And I'm sure someone might be interested in your old block once you swap it ;)
rogue 09-20-2004, 02:53 PM It doesn't sound like this guy will be able to install his own shortblock properly. I'm not even sure he knows what you guys mean when you say shortblock. :)
I do agree, though, don't have them machine out the old stuff, just buy a new one. The short block is the center part of the engine, basically just the crankshaft and pistons. I'm sure you can get a new one from lots of sources, including subaruwrxparts.com
pololla 09-20-2004, 03:24 PM i cant afford a new short block.. but if I get my crank machined and get new rod bearings will my car be ok?
Mulder 09-20-2004, 03:34 PM By the time you get done paying for the repair, you may be spending the same or even more compared to the cost of the shortblock. It is very possible that more damage will be found as the work progresses. At least with a new shortblock you know the full cost of the work going in.
Also before proceeding be sure that the heads are checked for damage as well, as you wouldn't want to end up with a new shortblock and bad heads. The cam bearings and journals should be inspected for scoring, and the valves and guides should be checked. If problems are found a completely new engine would be in order.
Take a look through the Private Classifieds here, there might be some STi short blocks or even complete engines for sale.
pololla 09-20-2004, 03:41 PM This is really helpful. The guy said that new bearings and some machining of the crank should fix the problem. He quoted me $1700 of labour plus $800 for parts from subaru.. so aprox $2500 total...
Btw. This is canadian dollars. The short blocks are around 1800 $ u.s dollars which will be close to 2200 $ canadien plus shipping to Canada.. so I dunno
RightyTighty 09-20-2004, 03:42 PM What would the resulting engine RPMs be if someone went into 3rd going fast in 6th? Isn't it really difficult to jam into a gear like that? Seeing as how the revs would be way out of the **** (edit spelled shiFt wrong, hehe) zone? Any syncro damage?
I would think that your engine saw around 9-12k rpm. :eek:
Harsh man. I feel your pain. A almost did the same thing to my old 83 Saab 900s, luckily I smashed the clutch back in before it went past redline. The car still saw 270,000 flawless miles before I sold it.
rogue 09-20-2004, 03:45 PM Why ship to Canada? Isn't Lachute canadian? :)
pololla 09-20-2004, 03:45 PM I know.. I am such a IDIOT!! It went right in. I wanted to throw it into 5th and 3rd is right next to it and I just went upward on abit of a angle and it freekin went right into 3rd I tried to clutch but it was to late.. I am just gald that I didnt blow my motor cuZ MY TUNER TOLD ME that I could have easily done that and my wheels would just lock up and piston rods would just start going through my hood.
rogue 09-20-2004, 03:47 PM And I agree, if it was enough to spin the bearings I'd imagine it was enough to flatten your cams or slam the rods into each other. Did your timing belt jump teeth?
DISCOPOPE 09-20-2004, 03:47 PM did they check your valves and what not?
i'd not be suprised if you had some impact with the pistons.

That's not true at all!

It's a Subaru. The pistons would have shot out through your wheels. :)

interference in teh yuor sti motor. werry bad.
It sounds like your shop is trying to do the right thing, but I'd be very wary of the motor, as everyone has said. See if they can at least pull the motor and pull the valve covers and inspect the cams, get an idea if they've been damaged.
RightyTighty 09-20-2004, 04:04 PM That's not true at all!

Actually your claim isn't true either (yes I know you're joking around)
Pieces of an internally blown H motor usually break through the top of the engine where the engine case is the weakest. Do you really think the heads on that beast would let a piston go through? NEVER!
Now going through the hood is pushing it. The intake manifold and everything else would probably stop it.
ok I'll shut up now and keep dreaming that I have an Sti. :lol:
imprez25 09-20-2004, 04:07 PM That's not true at all!

Thats what I was thinking as I read that! :lol:
Mulder 09-20-2004, 04:12 PM Well you did blow your motor, just not in a spectacular fashion.
Before you give the shop any go-ahead to repair the rods and crank, be absolutely certain that they fully check out the heads as we are advising. With that much of an over-rev there is certainly a chance that the timing belt stretched and/or skipped causing valve-piston contact and bent valves, as well as the possibility of cam lobe and bearing damage as I mentioned.
Once you let them proceed you will be responsible for the full cost of the repairs as per the estimate so you want to be sure that you will have a fully functional engine when they are done.
US2JDM 09-20-2004, 04:15 PM Get a new shortblock. Try not to be so Fast and Furious next time.
Boxologist 09-20-2004, 05:00 PM get a cheaper car. i gotta a feeling u will be entertaining us for a while. u gotta pay to play...
pololla 09-21-2004, 11:30 AM Wow.. your such a helpful guy.
rogue 09-21-2004, 11:59 AM Wow.. your such a helpful guy.
"you're"
And don't be so defensive, you're a brand new user and you did something silly. Take the good advice in here and try to learn from your mistakes :)
Also, Box's advice ain't half bad... have you thought about getting rid of the STi and getting something cheaper to learn on?

2000wrx 09-21-2004, 12:21 PM hehehe Yea what they said... uuug "MY TUNER SAID...." <--- if I ever say somthing like this please shoot me.
