smoke wont stop!

About 2 months ago i was leaving work and started my car.It stumbles for a second then runs like normal. i thought huh... thats wierd, and didnt think anything of it. Then i turned around and saw the smoke pouring out of the exhaust. Its white, so at first i thought coolant, probably headgasket. so i caught a big whiff of it, and oddly enough it smells strong like oil and gas (think of shoving your face in the exhaust of your lawn mower. or weed whacker). so i drive it home and it felt like it was running fine and parked it for a week until i got a chance to look at it. I go out, start it up, and it runs like a charm. no smoke whatsoever. so i drove it a month and about 2 weeks ago it did it all over ago, but now its not stopping and its thick. my oil still looks good, so is the coolant, so they aren't mixing. Another wierd thing is my oil smells just like gas. im thinking oil control rings? anybody have any suggestions?

engine- internally stock JDM B16a, endyn breather kit installed (not the problem, took it off and it still smokes like crazy) and intake/exhaust stuff.

any suggestions appreciated, i need this running again!!

probably should have added, it smokes at idle and under load

You may have some valve seal problems up in the head. My old BMW 4clys (2002s) used to do this. Don't recall any gas smell from the oil, though.

I think your first impression was right - busted ring. Do a compression check.

and dont let these guys drive your car

Long shot, but I've seen master cylinders fail and dump fluid into the brake booster, where it then gets sucked into the intake, creating huge amounts of smoke.

HA the last post had me rolling... but about the ring, if it were the oil control ring it wouldnt show up in the compression test would it? i mean i guess it could be ANY ring including compression but i havent felt any loss in power. about the valve seals, can they be somewhat intermittent? and then all the sudden go? valve seals make sense since it smokes at idle...

master cylinder should be good. replaced a year ago when i installed some brake things. still worth looking into i suppose.

It could be someone berkeleying with you...

I once shot 1/2 quart of ATF into a guy's muffler with a suction gun.

His car blew white smoke for nearly a week, it would only do it when it got good and warm too.

He was almost ready to pull the head off when I told him.

Since it stumbled and the exhaust stinks of gasoline, I'd be most suspicious of lots of unburned fuel. Be it from a stuck injector to a broken sparkplug.

Does this car have a vacuum module for an automatic transmission? Those can fail and you suck atf into the engine, which smokes white.

Sounds to me like a ring. If it were a valve seal, you wouldn't have gas in your oil. If it were a stuck injector, you wouldn't have oil smoke coming out the exhaust. I guess it's possible that the stuck injector is dumping so much fuel that it's washing out the cyl and allowing oil to pass through, but I would think that if it were running that rich, that it would barely run.

I think fox is on to something...

ok back to this. Did a compression test today and the numbers seemed to be good. Cylinders 1,2 and 4 were all within 5psi of one another and 3 was about 8 off from the highest. I called a friend of mine who is a tech at honda and he said the numbers are great considering their within 10 of one another. A friend suggested running injector cleaner through it and i did, not much difference. the smoke seems to be intermitent again, i drove it about 10 miles and about 5 of it, it would smoke with any throttle input at all, low or high. then about the other 5 is was only in really high rpms, which i think tends to be kind of normal for any b16 motor around 5500-8000 rpms. The smoke smells rich, slightly of oil but still white. Does anyone think i could possibly have water in my gas tank? When i was working at Honda in High School i remember every once in a blue moon cars would come in complaing of a miss (which i have had once or twice) and smoke, once it was all said and done they found that they had water in their gas tanks. does anyone know of any way to check this? i dont want to take my fuel line off of my rail because it will be under pressure correct? and i dont feel like draining my gas tank.

Check the PCV system and replace all emission/pcv valves.

Shawn, you are one funny berkeleyer . we need to go get a beer!

pcv system is good. I have an external breather/catch can that i can either vent to the atmosphere or connect back to the intake manifold. i tried venting it and also tried emptying it even though it reverts back (nothing in it). Checked all the hoses as well, all good and still smoke.

Check your fuel consumption. Maybe remove the injectors and pressurize them to see if one is bleeding down.

Shouldn't cause the smoke COLOR but you are having an issue somewhere so why not check all the unusual subjects.

Subscribed. I'm having the same problem in my EGT.

excuse my ignorance, how might i do this? im interested?

1: get an external fuel pump for a 1990 Ford F150 2: get two Mason jars 3: go to a salvage yard and get a fuel rail off a core engine cutting off all but the last injector prior to the regulator. 4: get some FI hose (I have about 3 feet total) 5: create a little board that holds the mason jars on either end, fuel pump, and fuel line so that the fuel pump picks up from one jar and the fuel rail holding the injector can spray into the other jar.

Use a 12V lawn and garden battery and TWO switches on the board, one switch should power the pump. Fire the pump up first and see if it leaks under base pressure then switch the injector on and off to see what the flow looks like.

One or more may leak.

White smoke. Leaking head gasket ,cracked head or block.

or you can just buy new injectors

Doesnt smell sweet at all like burning coolant, and coolant level has been consistant. Not mixing with oil at all either.

John Brown, thanks for the instructions and such. If i can track down the stuff i need ill be giving this a shot for sure. thank you.
