Blown turbo or Valve seal?

[wdskukm3]

Hopefully it's just the turbo leaking or blown. That will be a simple fix. But with just one spark plug burnt with oil it could be a piston ring leaking or worn. If that's the case then one of your pistons could be shot or even your block could be scarred. We'll just have to wait and see.

I'm far from a mechanic but if you know what you're looking at, its easy to determine what happened. Just look at the timing in the log and you'll know what happened.

Sorry What log are you referring too?
I see no log attached and whats has the timing got to do with this, exactly what are you implying?

you make no sense buddy.
shit happens and it has happened to many stock cars, plenty s65's have run bearings,where they all tuned?

I highly doubt tune is related.
but lets wait and see what the outcome is.

I'm not sure how you eliminate a tune from the equation. Even if a defective part from factory was installed in this engine, how can you prove running stock turbos past their efficiency range, 26 PSI is high, and adding a lot of timing on the top end, only way to keep car pulling hard when boost drops from 26 to 20 in this case, didn't play a role in shortening the life of said part.

Maybe poor quality fuel played a part in this. E85 is poorly regulated, one could also argue that a safe tune would allow for poor quality fuel without failure.

I notice no data logs were offered between the WR run and this failure. I hope i'm not the only one who thinks that suspect. I also hope certain members of this community aren't trying to protect a tuner. Judging by the harsh reactions on the WR thread, and the deflections already starting on this thread I feel that may be the case. To whoop_ass's point lets wait and see.

OP - no matter how I feel about our previous conversations I wish your car all the best. May there be cheap and speedy returns to the drag strip.

Did you really just say 'what does timing got to do with this' ? There is a potential blown motor (tuned by Paul) in question and you're saying timing has nothing to do with it ? Unbelievable.

Like I said before, I feel bad for what happened here and hope it gets resolved quickly.

I know what i said but again I see what you are insinuating is that the tuner is to aggressive on timing and this car has failed due to a the tune and only the tune or am I reading this wrong, do you even know how much timing a stock CS/GTS map runs on stock boost , I will let you in a little secret 14-15 deg with 17-17.5 psi @7k.

Any tuner with a bit a savvy wont run 20 deg, not matter how much octane you got, there is a point where you pass MBT and gain Zero.
if that is the case other tuners will be blowing these s55's up left and right.

LOL -- does a stock CS/GTS run 100% E85 ? Nope, didnt think so. But nice try, though.

There you go again. With more octane you COULD run more timing but that’s up to the tuner to figure out. Stop the nonsense until you have anything but a picture of a plug and oil on a turbo. My money is on a turbo seal and we all know plenty do and have run a lot more than 26psi on these cars. He wasn’t running 26 to redline but 20 so I don’t see your point there either. Just wait it out before spewing more baseless comments.

Did the damage occur at redline? I never saw proof of that. You are only proving my point of sheltering a tuner. Sounds like you don't respect people with different opinions. I certainly respect the idea it may be a turbo seal. If so why only oil on one plug as previously mentioned?

You are correct many people have run stock turbos at or above 26 PSI. Just not a good idea. If it were, why is PTF's high boost map suggested for PS2 turbo setup? I don't have all the answers sir, but I do have questions. Apparently you do not and know the answers. Please share

I'm sure running a tune on the ragged edge has something to do with it...

It wasn't on the edge at all, there was plenty of headroom in it. It's likely a defective piece of hardware that broke from the stress of pushing the car. It could've happened stock. If you aren't going to be helpful then don't comment at all.

What was the piece of hardware that was defective?

Meant to say likely a defective part. From the looks of it, it's a valve seal gone bad based on it being isolated to one cylinder.

hopefully it's a valve seal.

Lol just get off this thread buddy

Yes I’m sheltering the tuner UNTIL there is at least something concrete to point a finger at. Stop making assumptions. Tuners must hate guys like you. Right away with zero diagnosis you choose to roast the tuner when it can be a million things. OEM plugs for example have the ceramic part break very often and people recommend against them. I’m sure if you had one break or a charge pipe break you’d blame the tuner for that too right away. Chill with assumptions why does it matter to you to pin this to the tuner so much I wonder.

The scientific community must hate guys like you. Get all defensive when someone asks questions. Lots of guys running ethanol with no problems until these new tunes come along. You would be a fool to not start there. Fastest tune in the quarter mile and with a broken car. Batting .500 so far. After tune is eliminated from the equation we can move on to parts.

Blaming BMW or their parts vendors seems like a poor choice since this is a one off incident that I can tell. Once again you can prove me wrong, link threads of similar issues. You do the math sir, nobody else has an issue like this and they are all running different tunes.

I've used two separate ethanol tunes myself and had no issues with spraying oil everywhere. I've heard the quote the best is what you know. Well I know two tuners with no issues reported so far. Can't say the same in the OP's case.

For the record you should be trying to convince people it isn't the tune with evidence. Not deflections. You sir are dangerous to a community like this. Call people out for asking questions, and to provide proof. Just like many people on this forum i like to read and educate myself as well as others if possible.

Even if this had nothing to do with the tune, that's great! Then it will put future customer's minds at ease. If the tune is part of the equation then people deserve to know.

You’re not questioning, you’re finger pointing and blaming. Is that not clear enough? Read my posts again. Questioning is fine and I’m curious as well but that’s NOT what you’re doing, or at least its maybe 10% of your posts.

Blaming turbo seals or blow by is actually finger pointing. So I guess we will agree to disagree.

By the way, isn't placing blame on the failure exactly what we are trying to accomplish?

Ok so I win this argument then. I’m good with that. JK

Actually PTF recommend I try the High boost map on E40 mix but it misfired after 6k. Pure turbos are recommend but 26psi is possible and safe under 6k rpm with E40. The custom tune OP has tapers boost after 6k so that shouldn't be a problem.

Thank you for the info. I never tried the high boost map. So far I've stuck around 24-24.5 beak boost on my stock turbos. I really haven't heard of guys exceeding 26 with much success. Have you seen guys effectively running them higher? My worry wouldn't be on the dyno but back to back runs on the street or strip in high heat/humidity.

Correction on the boost, it's 24 midrange with 18-19 taper at redline. I'll find a log to post up. It's possibly a bad batch of e85 or my station switched to a winter blend which I will know shortly.
