It's a neverending nightmare...

[MountainDew]

Well looks like I'm back... Some of you may know that my car had really smoking issues before. So I replaced the headgasket, did some minor machine work and new valve seals installed.

Then my car wouldn't start for a month so I did the 1G CAS swap..

Car has been running pretty good. Until a couple of days ago. Yes, I had gotten on it. Boosted and let out around 6800. Did another pull then went home. I got home to discover lots of smoke and a wonderful ticking noise from my engine.

I've just been driving it how it is, but now I've noticed it only smokes horridly whenever I downshift or decelerate. I am out of ideas, and am just completely fed up with this car. Oh yeah, and this has to happen like just a day or two AFTER I buy brand new tires and put new leather seats in.

I've pretty much lost any hope for this car and am about to cut my losses..

Are you possibly running low amounts of oil in your car? Do you notice your oil pressure being on the low side?

You could have blown the turbo and may also have rod knock with that "ticking" sound you speak of. Check for shaftplay and play with the throttle at idle try to come to a conclusion where and what the ticking is from

Nope, but when the ticking and smoking started, I noticed the oil on the dipstick was right on the add mark. Oil pressure is the same it's always been, about half way or a little more towards the low side. But nothing ever dangerously low.

Also, I had E-10 89 octane in the gas tank when this happened. Think that could have caused it? I was in a hick town, about to run out of gas and that's all they had for premium. The tick sounds really close to the injectors, we kind of thought it could have been injector tick and maybe it ran really rich or lean. But now I have 91 in there.

Car might be gone this weekend anyways, but I would like to keep it. I'm just tired of dealing with it. I don't think it's the turbo, the turbo is a brand new t-25. Only like 2k miles on it.

I'm guessing bad turbo. Cause the only time your seeing smoke is when back pressure is being put on the turbo. When you have back pressure oil is leaking onto the hot side of the turbo and burning up and producing smoke.

Makes sense, but what about the ticking? That's what has really got me puzzled.

 

[sherms_gsx_tank]

sounds like the turbo to me definitely check shaft play. then as for the ticking it could be the rods take a long wood or metal peace that you can stick to your ear to and place it on the block move it around and the louder it is to the base of the block the more likely it could be a cracked rod. if not i could just be lifters or something that you never noticed before till this happened.

 

[98mitsuGSX-SD]

I was just thinking that the ticking was regular ol' 4G63 lifter tick. The ticking should go away when the oil is filled to the right level and warmed up. Everyone suffers from various degrees of lifter ticks. Some more than others.

 

[sherms_gsx_tank]

and im not familiar with you situation with the car or how long youve had it but dont worry about lifter tick that is with every 4g63. ive just noticed with my experience and friends that some people dont even notice it until something else goes wrong and they start paying more attention to their engine and the sounds it makes

 

[MountainDew]

But it's something that is definitely noticeable. I eliminated all lifter tick when I got a valve job done.

Also the ticking starting to occur when it started smoking again. It has plenty of oil added and it doesn't go away when warmed up.

Sorry maybe I missed this part but where is it smoking from? Engine bay Im assuming? If so is it possible the oil feed line has a hole?

My bad, it's smoking out of the muffler.

Seems to only be real bad when I downshift or decelerate. Basically at 20 vacuum.

No problem, I have another question for you, what color smoke is it? Sorry Im not trying to play 20 questions here!

Call me crazy, but boosting on low-octane gas is bad... or am I the only one who noticed that? That's kinda why your gauge says, "Premium Only". I don't believe it's just for cosmetics.

 

[Boostin91TSi]

I think one thing that caused the problem is putting 89 octane fuel in the tank. If you are boosting, how much pressure? It's like on my SRT-4, I can use 89 only IF I have no choice and run at stock boost. But fuel octane is a big thing on forced induction cars.
Good luck on fixing your DSM, it is a lot of work, but the rewards are sweet at the end.

 

[Loewen21]

You say the ticking sounds like its coming from the injectors?? Trying unplugging your isc and see if that makes a difference.

 

[coeclipse12]

I think the ticking has a lot to do with the 89 gas... I worked at mitsubishi in florida and I asked the shop foreman about this before. because I wanted to get better gas milage because 93 burns faster... he said if u use anything less than 93 it can and ###### will start pinging.... in shop terms I'm sure that's ticking or something damn close... so needless to say only use 93 or higher

 

[gsxeclipse97]

Well i have a simialar sound coming from my car and i only use 93 or higher.

 

[SlickGSX]

I have seen newly replaced valve stem seals slipping down after some driving, that could be something to look at.

+1 for the turbo. I'm 95% sure that your T-25 is toast. I just went through the SAME EXACT thing. Swapped it to a brand new EVO III 16g and the thing runs like a champ without the tiniest bit of smoke. You mention that your car was smoking before and that's why you re-did the headgasket and everything else. It's possible that your turbo has been going out on you for a while now and you've been mis-diagnosing it. I wanted to drive my car off a cliff after repeatedly fixing things that might be the culprit of smoking, but to no avail. The worst part is that after you make an adjustment, in your head you think you fixed it and maybe it did stop smoking a bit, or maybe you just didn't notice it. My T-25 would be off and on. Maybe it didn't smoke for a whole week (or I didn't notice it) and then, every stop light I was at for the next 2 days I would notice some smoke. One thing for sure is though, when your turbo does go out... there's no denying it, and you my friend... have a blown turbo.

As for the ticking... lifters maybe (even with the oil being filled sometimes I still hear lifter tick off and on), depending on your mods and how much boost you were running, putting 89 octane and then going out for a redline pull could definitely cause some damage. I think it's more paranoia at this point. I say change the turbo and and re-diagnose. Hell, it's gonna need a new turbo anyway... at the very least, slap another T-25 on there.

turbos cars are fun but not reliable at all unfortunately

Did you even read my post? I live in Kansas and I was in a hick town and the only gas station had ethanol 10 89 octane for gas. It was either that or walk/tow back....

 

[mach4g63t]

I did, and I personally have done that too. Hell yes it's better to drive slow on shitty pump gas as oppose to walk, but that doesn't mean go run down the street and boost the crap out of it. Just saying, that's all. Didn't know if you knew about that or not. Just putting it out there.

That is a completely faulse statement. There is no reason a turbo car can not be reliable. What makes the cars unreliable is the person doing the mods that is not doing them right or just not maintaining their cars.

Or you buy a car that was messed up to begin with.

I'm going to run seafoam and change the oil. Hopefully after that I can further diagnose my problem.

 

[95CarbonEclipse]

I'm telling you.. i've been down this path before. Save yourself a lot of time and headache, and most likely money, and pull your intake and check your turbo for shaft play... I can practically gaurantee you that it's shot. I'd fix the turbo and then fire 'er up and diagnose the ticking then.
