Got an issue and need some serious insight

[slvr08gt]

Hey everyone,

I installed a used single hellion kit last weekend. After a day of driving to work and back on the base tune, I noticed I was seeing some smoke behind my car. On the same day I had to pass a car to avoid another car, I got in to boost about 2psi and it left a HUGE smoke cloud as soon as I went in to boost.

I got the car home and pulled the air filter to see if there was any shaft play our anything not normal. When checking the turbo, I noticed the turbo had a little left to right shaft play and the inside of the compressor housing was coated in oil.

At this point I considered the turbo done and decided I would just sell the kit and move on to something else. I let the car sit for the rest of the week to uninstall it today.

I removed the kit today and all was going great until I removed the coupler going from the turbo to the intercooler. Literally, about half a quart of oil came pouring out from the coupler. It must have been collecting in the bottom of the IC. At this point it was clear that the front side compressor seal must have went in the turbo and that was the reason I was getting some smoke from the mufflers. It's also important to note that the turbine side of the turbo was dry as a bone.

I continued to return my car back to stock and finished a couple hours later. On my drive back home, I noticed that I was still seeing smoke coming from the back of the car. I figured it was some residual left from the kit. I continued driving and decided to get in to it a couple times to see if I could maybe burn or blow the remaining residual off. I got in to it 3-4 times going up to 4500 rpms and it billowed smoke like a freaking choo choo train. Mostly a blueish/grey color. I was about a mile from being home so I decided to just take it easy and drive normal. When driving normal, it still smoked and the smoking increased with RPM. It's smoking easily twice as bad now with the turbo kit not installed!?!?!?

Got home and parked. Walked behind the car and noticed that the smoke was only coming out of the drivers side exhaust pipe.

I'm at a loss of words right now. When I removed the kit I basically removed every pipe on the car that could have had oil in it. The only pipes left that could have any oil in them would be the over axle pipes and the mufflers.

The only thing I can think that it may be is there is still residual in the over axle pipes and or mufflers.

That's all that's adding up to me. My oil level is good and it doesn't smell like fuel. No CELS's also.

The only things I can think of doing is to take my car on a much longer drive tonight to see if I can burn off the residual oil or remove the mufflers and run the car to see if it still smokes. Does anyone know if the gt500 mufflers have the fiberglass packing in them?

Any insight or steps I can take to trouble shoot this?

Please keep negative comments about the hellion kit to yourself. Yes I know it doesn't have the reputation.

Thanks in advance.

Also worth mentioning. The car drives smoothly as it did prior to installing the kit. Doesn't seem down on power one single bit.

I would take that muffler off and run it, just to make sure its just in the muffler.

 

[GeorgeInNePa]

Probably just in the muffler.

Toss the stock ones back on and go for a ride, see if it smokes.

Do the plugs look good?

Wish I still had my stockers. They're in a land fill somewhere by now, lol.

Plugs I pulled looked normal. All were dry and dark grey in color

Could be a little oil in the intake but it should be a small quantity. Give it another week and the smoke should disappear. Maybe you could put a 'diesel' or F350 badge on the trunk until the smoking stops.

On the bright side, at least you know what the problem is. You could send the compressor in for an overhaul if you are still interested in FI. You've gone the the install (and uninstall) so the next time ought to be lightning quick.

Lmao at the f350 badge comment.

Between the turbo going bad after a couple days and my car acting like this now, I'm a lil skerd to even think about throwing another kit on.

Just got back from about a 60 mile highway cruise. Did quite a few short pulls. Seems like the smoking may be getting lighter but can't tell for sure because of the dark.

One thing is for sure though. When I put my face down by each exhaust tip, the passenger side smells normal but the drivers side definitely has a exhaust/toxic weird smell to it.

Can anyone confirm if gt500 mufflers have the fiberglass material on the inside or not?

 

[nyuk98GT]

slvr08gt:

Can't comment about the fiberglass material in the GT500 muffler. I did forget to ask in my previous post if you have a borescope. You might be able to peek inside the intake and see fi there is any residual oil in there. Also, you could take a look along the muffler tube(s) to see if there is any oil on there. It doesn't help with the innards of the muffler but some traces might be lingering on the outlet tube.

I understand about the hesitation to reinstall the turbo. Jus't don't be too hasty to get rid of it based on the seal problem. You'll get the itch again. Right after the buyer confirms receipt of the parts.

Take the mufflers off and run with just the over the axle pipes, aka muffler deletes. See if it still smokes. If not, buy some new mufflers. or drill holes in the bottom of the ones yoiu have and let the oil out. LOL

 

[Bigmack2012Gb]

I would take the mufflers off and drive around to see if it still smokes in my opinion. Also have you done a compression test on the car after the incident?

 

[NATAS]

On a previous post someone mentioned there could be residual oil in the intake manifold. I would agree with this comment after reading there was a quart of oil in the boost tube (Turbo to Intercooler).

If you have the talent to install a turbo kit and remove it then removing in the intake and flushing it will be a breeze.

Forgot to update the thread the past couple days.

I went out for another long drive the following evening and did some light pulls. By the end of the 70 mile cruise, smoke was no longer coming out. After driving this morning and this afternoon, its confirmed that the smoke is gone.

Car is still running great and still no CEL's so im pretty confident all is well.

Pulling the trigger on a Paxton 2200SL today so she will be boosted again next week. Hopefully without any issues.

Thanks for all the help and hints everyone!

good deal. Do I hear a cheap hellion kit?

May be a good idea to run some seafoam through the engine just to clean up any residue if it went into the combustion chambers.

I thought about trying some seaform just for good measure, but I have never used it and it sounds kind of complicated to used correctly. I might be overthinking the whole thing though.......

 

[ochoblanco]

All you need to do is feed the Seafoam into a vacuum line as its running. Then go hammer on it until the white smoke stops.

 

[DSargent09]

Who did you order your paxton from? Also who will you be allowing to tune it.

 

[JEWC_Motorsports]

You should know by now the hellion single kit is garbage.

Thanks. I think I'll check for some youtube videos

Who did you order your paxton from? Also who will you be allowing to tune it.

Bought a used tuner kit with 1500 miles on it for 3600 shipped. Saved close to a $1000 considering the shipping cost to where im stationed. Spoke with Shaun today over the phone and he pretty much sold me on his tuning proccess. There have been very few mustang tuners that I have spoke to over the phone that actualy made me comfortable with having them tune my car.

Most I have spoke to either act like they dont even want my buisness, are rude, or just look for ways to upsell their products.

I guess I will know if he is as good as people say he is in a week or so.

Yes yes I know.

I got a good enough deal on it that I just couldnt pass it up. I seen a couple guys with them that didnt have a single issue and put down pretty good numbers. To be completely honest about the kit. I didnt have any fitment issues and the install went through pretty smoothly.

If if wasnt for the turbo taking a crap, I think it would have came together nicely. Oh well, I didnt really take much of a hit from what I originally paid for it.

Lesson learned

same thing happened to me on my 06. The turbo seal was leaking. My car smoked for weeks. There was a ton of oil in the mufflers (they were stock).

My smoking thankfully was gone in a couple days. It does however still smell like nasty burnt oil though. May be a good excuse to get a new AB, lol.
