Default Crap, I have white smoke coming out the tail pipes...

Whats going on guys? Another day in paradise, I thought all my issues from my fp green install had been worked out but today I have noticed a bad issue, when my car is warm I have noticed white smoke coming out of the tail pipes. When the car is cold I have not noticed the smoke.

I need some help pin pointing what could be the cause. I do not have a catch can, the turbo I had installed was rebuilt(FP Green) prior to install, coolant levels have not decreased. I initialially had no oil consumption but noticed the level had gone down this week, I added a half quart of oil to top off oil level and have noticed the smoke appaearing shortly after. I'm going to do an oil change on friday night or saturday and am planning on parking the car till then when I get home from work, which is 10 miles away. I will see if my oil looks like a 'milk shake' when I do the change. I'm praying its not a blown head gasket or that the turbo seals already are failing but I know they are possibilities.

If there is a basic cause I could be missing possibly from no catch can? Which I doubt would have anything to do with coolant burning, feel free to chime in an educate me. Also I have not noticed any driveablity issue except that when my car is warm and I start it up the car will idle rough for 5 seconds and then go to 750rpms and be smooth. The car's temp gauge has never said the car was running hot since the install. When i pop the hood while the car is running and warm and search for smells, I find none. Your thoughts...

Mods if it is helpful to know.

maybe you got a little coolant in the uppipe when doing the install?
I do know that when I removed my turbo and tossed it back on, I got some coolant in my uppipe, and took a while for the smoke to clear.

Also, open the oil filler cap and see if smoke is shooting out of there also

Thanks for the tip, I will check it out when I get off work. I have run the turbo for about 1000 miles since the install and i just started noticing the smoke this morning, but also saw it on my lunch after the car warmed up so I know this issue is not going to miraculously go away. I figure if it were coolant that leaked into the up pipe from the install i would have noticed right after the install and not 1k after. Keep the ideas coming.

I took a smoke break, and started the car and ran it for 5 minutes, with the oil cap off didn't see any smoke coming out of it but I wasn't seeing white smoke come out of the tail pipes, it would appear it only happens once the car is at running temperature not before.

I just installed a Turbo XS FMIC too. It's probably coolant so don't panic just yet. No codes being thrown?

No codes have been thrown, car feels fine I had it in boost one time today before I noticed the smoke it ran like a champ, its been 1000 miles since the FMIC, turbo, injectors and inlet went in if its worth mentioning.

One more symptom I've noticed is that when I turn into a parking spot at low speed and clutch is in the car idles like crap feels like its going to die. It happens regardless of whether my tank is full or low I have looked for hoses that have blown off which i had two initially after the install, but no dice. I will look a lot harder when I get off work shortly. One other thing I noticed under the hood was the rubber coolant line going from the coolant overflow to the turbo has a cracked end where it connects to the turbo, it still appears to seal and when the car was at idle I didn't see any fluid leaking.

I was smoking pretty bad on the drive home, definitely embarrassing. I checked my oil level and coolant levels, both are at the same level as before (full). I stuck my nose behind the tail pipe and it smells like oil, definitely not coolant which I'm fond of smelling with my old accord. If I didn't have ice hockey tonight I would drain my oil and take a look going to have to wait till tomorrow night. My car back fired a couple times on the way home, sounded like a gun shot. I am praying its excessive blow by from no catch can.

It was tuned for 91 octane map and for e85. Now that everything is cold I noticed coolant went down about an inch in the overflow, not looking too good.

You say the smoke smells like oil? Did you maybe blow a piston ring or something?

Did you prime the turbo before starting the engine the first time with it? It could be a turbo oil seal for what you are describing. Ask me how I know that

It distincly smells like oil and e85 out of the tail pipe. Engine was primed prior to install I assume I had the turbo and fmic installed. I'm thinking I blew a head gasket at a minimum but if I had my temp gauge would have shown some overheating I would presume. What is strange is that I noticed no difference in driveability and could hear no engine noise, car idled fine. Tonight I'm doing the oil change after work, if no indication I will disconnect the dp and look at the turbo then go from there if necessary.

doesn't sound to me like a headgasket at all. My money is on an internal oil gasket in the turbo, piston ring, or something simmilar.

I would take off the downpipe and start looking there.

I would be shocked if it were the turbo since it was just rebuilt by FP but it could definitely be the culprit given my symptoms. I will probably have the time tonight to remove the dp and get a look.

I setup an appointment at the dealer on thursday for a leakdown/compression test. IIRC when I started the car yesterday with the oil cap off I think there was air blowing out...

I drained my oil tonight and unfortunately it looked like a milk shake. It had bubbles in it and the color is brown and it has a burnt rubber smell to it. I noticed a couple of specs of metal on the drain plug, I assume and hope this is normal. I will post more info as it comes in, with any luck its just a head gasket and I didn't do engine damage...

My guess goes for the head gasket, If It was a Broken ring land then It would just burn oil and not discolor it like your seeing. A blown head gasket makes more sense.

And for the Oil cap being off and feeling air blowing out Is normal, Its just blow by.

Sorry to tell ya....but your engine has cracked pistons and/or rings. It might as well be a blown head gasket.

My mechanic thinks having a couple of specs on the drain plug is not a big deal, the engine will get inspected. I'm talking about two specs the size of a grain of sand. I'm hoping there is not any engine damage, and that my issue is isolated to being just a blown head gasket. Anyone have any ideas on how I would know there is internal engine damage aside from head gasket? In regards to the comment earlier there was air blowing out of my crank case with my oil cap off, but I checked on my envoy and it did the same thing so no worries from that symptom.

^^^none of those are normal . prolly blew compression rings , from the sounds of it ,.Head gasket problems, don't include metal in the oil.

I going to sit on this for a little bit and figure out which direction I want to go.

I'm thinking the reason I blew the headgasket was from the initial weekend with my ride after the install. I had 2 hoses blow off, one on the t fitting and one being fuel pressure to the intake manifold. I had zip tied the t fitting but it wasn't enough i needed a barb t fitting to hold the hoses on. The hose on the t fitting I found quickly. But I noticed shortly after I plugged the vacuum hose back on the t fitting the car was still not idling right. The car felt fine while driving if you can believe that, it idled rough though, I assumed it was a idle tune issue after plugging in the t fitting hose back in, it wasn't. It was the fuel pressure hose. I probably got into boost 10-15 times with the fuel pressure hose blown off, with a lean condition and a lot of boost, you run into these kind of issues. I'm going to buy a clamp for the fuel pressure hose, definitely going to be an expensive lesson.

I just talked to my mechanic and the gameplan is to do headgaskets and upon further inspection go from there. He told me he has rarely seen warped 2.5l blocks. He also said that my worst case scenario is probably that a cylinder(s) wall has a crack and coolant is leaking in to the combustion chamber via the crack. I will get the car towed to his shop this weekend and find out next week the ultimate outcome. Cross your fingers for me.
