That's a little harsh.. he's learning, everyone starts somewhere - his first lessons will be expensive ones though lol

op good luck, hard to say but it seems like a tune. if i were buying a used car, i would always buy from a car forum so i can look up the user's history. you dont know what kinds of things sellers do to their cars before they trade them into dealers, leaving them with bad tunes/tunes mismatching their part outs, other problems etc.

good luck

 

Your right, I really don't understand tuning at all. Thats why I'm on here to help figure it out and understand what to do better next time. If I get the new engine I may just have to leave it stock and just leave the exhaust on there, because I really don't know anything about tuning, and I don't want any of those parts to void my warranties...

 

I'm really just confused because I got some people saying it was not tuned and thats why this happened, and on the other hand people say it happened because it was tuned and it was not done right. So either way, tuned or not, the engine could mess up is what I'm getting. The only way is it get it "professionally" tuned. I live in Louisville KY I highly doubt there is any professional tuning shops down here. And even if I did get it tuned and something were to go wrong, that tune will for sure void the warranty, but I might be able to get away with having some of those parts.

 

It likely blew up due to a lean condition from the aftermarket parts coupled with colder weather that pushed denser air into the engine and leaned it out further. Just a guess. Knock sensor can only do so much. Were you going up hill when it happened?

 

I could have gone either way.

someone put parts on and didn't tune it and eventually KB

or they took some parts off of it just before they sold with no tune and eventually KB

I took the bus two hours to get installed/tuned by Chad Block. Worse came to worse you could head up to AMS or Buscher, two of the most reputable Evo specialists in the nation.

 

The reason that people are saying it either could have been due to lack of tune or a bad tune is actually the same.

Bad tune = leaning out (too much air/too little fuel)

No tune = some of the mods you have are meant to bring more air into the engine, thus without a tune the amount of air is increased but the amount of fuel going in is not and the result is leaning out...

I bought my VIII without knowing everything about turbos, but I did have a little bit of knowledge. The thing is it seems as if you bought a very expensive car with no knowledge of how it works. It is a common thing and it usually ends up biting people in the butt. Make sure the research comes before you buy. You do not need to know everything, but at least some basic concepts. With that I say if you really do not know anything, then make sure you by stock. I am not trying to be mean or bash you, because I can completely understand the position you are in and the one you were in before you bought the car.

Since buying it and having the engine blow are already in the past, you are doing the right thing by finding out what went wrong and why. Along the way, try to retain the knowledge that is presented about turbo systems and how tunes can work, or at least do a little research on AFR's...

I personally say whether it was a bad tune or no tune, it blew due to leaning out. That is of course if everything else maintenance wise checks out. Good luck and I hope they do not jerk you around too much.

 

Whomever customer sold it to the dealership had it retuned back into stock and just left with all the upgrades for the next owner. That's my theory.

 

+1

for all you know it could of previously had a big turbo swap and was returned to stock cause the owner new the motor was about to go.

 

I agree with Scotty.

Either way, a bad tune/no tune will essentially do the same thing. I really believe that the car leaned out too much. Which is why I said in the first post "Check the fuel pump relay." I really think that is bad, which was making the car run leaner in the first place, and then with the aftermarket parts + the cooler weather, and either the wrong tune or no tune prolly blew the engine.

And you say your confused because people are saying different things- well that's because you just listed some parts on your car and said "your engine blew up.. What happened?" We have no idea what happened really. We are just going off the most likely things that usually cause a blown engine. We can't pull a log out from when you were driving and see where all the knock occurred, what boost your running, what your AFRS look like, etc.. We're trying to help by telling you the most probable situation. A tune is the single most important mod/thing you can get for your car.

 

What's a Vehicle One Premium service contract? Is that an extended warranty? Look at that policy and see if it covers things like catastrophic failure. Since you were able to buy and sign an agreement that they will cover the car "as is" then they should stick to that.

 

Not tuned or badly tuned is basically a same on modifyed car, since a tune from factory is for an unmodifyed car stock car.
The rightly tuned car with a right fuel is bullet proof, unless you miss shift and over rev the engine.
What type of fuel you were using?

buying used evo's (or any tuner car) is a sketchy market for this reason, kids mod cars and do ****ty installs then have there stupid friend tune there car, and once there car starts having problems the trade it in to a dealer that doesn't know better, you really shouldn't buy a used modded evo unless you know about the car seen and the car itself, you should always do a full leak down, compression and boost leak test, if a evo is modded always get the tune checked by a reputable tuner,

 

Boost may have been out of the question at the time it let go, but prior abuse through excessive torque, over revving or knock could have weakened it to a point of near failure.

 

You made a poor decision to buy an Evo.

What he's saying is that the previous owner likely traded it in for a reason.

The car threw a rod. Obviously the car then died and oil was all over the place. Like I said I was doing 70 on the interstate in 5th. Not sure but I don't think I was going uphill. The dealership I bought it from had it towed back to their shop to take a closer look and hopefully determine what really happened. Once I get more info I will post it.
