Default EJ253 Rod Knock have to rebuild engine.

Ok so I bought my 2009 Impreza 4d from I dealership in SLC about two months ago. They said they had changed the oil just a few days before I finished the sale. Fast forward to last tuesday. Im sitting in the starbucks drive-thru with my windows down. as i pull forward i hear knocking. so I look it up when I get home and decide it might be a lifter issue. I take it in to a local subaru dealer and they say that it is something with the short block apparently I was super low on oil so my block is toast. It's out of oil! thats odd cause i got it two months ago with a fresh oil change and I only drove it like 1500 miles, and it's doesn't drip(I check every day). I guess that means it was burned out my exaust. As it turns out it was rod knock and the inside of my short block is destoried.

Now the subaru dealership I took it to says it could cost anywhere from 3.5k to 8k including parts and service to fix. Im thinking 8k!!! I could fix it for cheaper.

The dealer I bought it from says that they will get me the parts at cost and give us a discount on labor. But that still means it could cost upwards of 6k.

If im gonna pay 6k id rather do it myself. Here is the iffy part though. I have never done engine work.

Knowing that would it even be possible for me to do it myself?

Any ideas, thoughts, suggestions are much apperciated.

*Also just an Idea but I could build it with more whp byself for cheaper than the dealer could build it stock right?*

Thanks

In theory, you would be able to do it for cheaper than the dealer. But, you're not just paying for parts. You're also paying for time. Time equals money. Have you looked into getting a whole other engine instead of rebuilding your current one? I'm sure that would be cheaper than 6 or 8k.

I've wrenched on my car for 5 or 6 years and I don't feel comfortable enough to rebuild an engine.

P.S. Burning 1 quart of oil per 1000 miles is considered within spec on our engines! Please check your oil frequently!

I was part of an engine rebuild and wasn't comfortable with it. Hope you have a good mechanic friend that likes engine builds!

ok, yea I have no quams about building it but as you mentioned I would feel very weary about driving it after. I would definatly take it to a mechanic throughout to just look it over. Also time wouldn't be an issue I have three days off my job a week so.

If i were to buy a new engine. How much more powerful could I go with out having to change out trany and such?

Also I get the burn rate but considering i'd only driven 1.5k miles and it holds more than 1.5 quarts i didn't even think about it.

I saw an '10 sti engine for 4.5k the other day. I'd have to do a helluv-a-lot more than plop it in though to get it to run huh?

also where would you consider buying an engine from. it seems super iffy to do it online.

I have an associates in automotive systems and service. That being said I've rebuilt a couple motors (never and impreza though) and if you have a good instruction/service manual its not that difficult, but as stated earlier its all about time. And you could definitely get a new motor or rebuild yours cheaper than the dealer.

Pro tip for the future - If you buy a used car, check the oil. The dealership said they changed the oil, but who knows? Maybe they didn't refill it all the way.

And with any car you own, check the oil. Going 2 months without doing so is just asking for something like this to happen!

Yeah, doing all that work to rebuild and install an engine probably would make you tired.

The transmission in the non-turbo cars is essentially the same as that in the WRX. In other words, you're never going to make enough N/A power to risk breaking the transmission.

I've bought 2 engines off Ebay and haven't had any issues with either of them. With that said, there aren't nearly as many listings for the newer engines on Ebay - it's very easy to find listings for the old DOHC EJ25Ds like mine, but not so easy for the EJ251s and EJ253s.

You can check www.car-part.com for engines - plenty come up there. I imagine there are local Subaru shops that could source an engine for you - search the Rocky Mountain forum and see what shops you can find. (Those shops could also do the engine swap or engine rebuild and I'm guessing would be substantially more affordable than the dealership.) Search for motors in the Classifieds here and on rs25.com.

If you're not too mechanically inclined, putting a short block together may not be a viable option... at least in my case. You may be better off buying a built (or stock) short block and then just doing the build from there on out.. that way you at least know the short block is good.. All you'd need to do from there is get your heads to a machine shop to check the decking, cam journals, valve lashing, etc... then get some ARP head studs... Oh, and gaskets of course... Up to you.. think of it this way, if you bought all the parts yourself, did the build yourself, and clearances were bad - you'll destroy the motor fairly quickly.. thus ending up being more expensive in the long run.

Hope this helps.. I've just recovered from a spun bearing in my ej257.. went the "built block" path and it has cost me about 7k already - that's with friends helping me...

Hey, nice car!

One thing that I have to say is you should of been checking your oil once a week as preventative maintenance which would of kept this type of problem from happening. So remember that for the future, ok

Also, there are a few oils that are way better than most of the "regular" ones idiots here like to use... That won't burn off and do stuff like this... If you want a list of these "good" oils send me a pm and I'll get back to ya

There's many sellers on ebay that sell used engines out of subaru's with varying mileage.. Some of them would be an exact match for your year of car and motor. Do not have your current motor rebuilt as there are a bunch of parts that will have to be replaced because of bearing material being pumped through the engine... and it would be cheaper to get a used longblock which is the heads and block and put that in your car and then sell some of the parts off the blown block or simply keep them.

A turbo swap would be much more than what you have and more intensive than you are ready for. So, for right now focus on getting another used engine so you can get your car back on the road

Thanks!

Im blushing so far all of you are so friendly.

Im just asking for a round about parts price. I am not thinking of building myself anymore. I just want an idea of how much the parts would cost to see if maybe i'll have my shop do it.

hey and guys thanks for all the help so far!!

Might want to plan about 4k just for parts.. you might run into a time period where you need parts but you seriously cannot think of them right now (trust me, I budgeted 4.5k and I'm nearly 7-8k in..) but that's for a built block

I replaced my shortblock, and had heads rebuilt for around 1200 total. But that is far from an actually rebuilt engine. You can get a remanufacted engine for around 3k ready to install, with a 1 year warranty etc.

It really depends if you need a long block or if your heads can be reused and you can just buy another short block.. depends if metal got up in the journals and ate them up.. so you'd need to take both heads off and cams off to see. Just something to keep in mind.

I understand the differences between the 253 and the 255 on the inside but was Im asking is what else would I need to have installed if I were going to install a 255 in my stock 2.5i.

my current engine is toast. So if possible what I would like to do it take a EJ255 and put it in my 2.5i. I want to know what other oem or aftermarket parts i would have to purchase to make this clearly more powerfull engine run im my car.

Engine, radiator, clutch, ECU, entire dash wiring harness, engine wiring harness, hoses, fluids, lots of labor, etc etc. Again, find a shop that works on Subarus in your area and I'm sure they can tell you what it would cost to do a turbo swap.

My advice is that if you want a WRX, just buy a WRX.

If only I had the money to just go get a WRX. I figured while the engine was out i'd see if it was possible.

Thanks for the answers guys! This is an awesome community.

Okay don't get excited by all the talk of turbo. You can't handle it (the swap) and it isn't worth it. Just get a used longblock and have someone put that in. I cannot imagine that costing more than $2.5k

If you found someone off the forums to do it for you I am sure you can keep it under $2k. If you need a motor just pm me. I have a friend that deals in parts cars and would be able to find you a longblock. He would even put on a new timing belt and ancillaries if they are needed.

Ya I'm not gonna do the swap I'm just gonna replace the long block, get a lite weight pulley , rear sway bar, short shifter with bushings. And maybe a cai.

I would've done the swap had it been closer to 5k

I would skip the lightened pulley or pulleys and get this clutch kit:

http://www.ebay.com/itm/XTR-STAGE-1-...37f915&vxp=mtr

I have the 2.2 NA xtr stage 1 clutch with the lightened flywheel and I love it! This one would be about the same and would fit your tranny just fine for your year of car.

Edit You could also get the stock clutch with the lightened flywheel for a few dollars cheaper. It would still shift a little better than the stocker with the heavy boat anchor of a flywheel... in this link http://www.ebay.com/itm/XTR-HD-CLUTC...245081&vxp=mtr

Well, it depends on how much money you have left after finding a used engine and then getting the clutch and flywheel and stuff.

You can look in the exhaust section here in Nasioc and there should be some info about your year of car for the exhaust and stuff.

I agree for the most part. if you're going to be stock for the most part, stick with a stock clutch and flywheel.. don't get a lightweight flywheel unless you really know the pros and cons.. same goes for the pulley. If you're planning on pushing more than stock power, south bend makes a good and affordable clutch.. I hear nothing but good things about them.. heck, even bought one myself.. would have used it if they sent me the right one (sigh).. stuck on a competition stage 2 clutch now that likes to chatter every now and then..
