no oil smoke till 5500+rpm and really bad at 6500-redline(7200) i have a hatch si with d16z6. 100,000 miles or so on motor. i have no power loss that i can tell but damn you wanna talk about a f*n smoke screen. like nothin ive ever seen. but like i said nothing till vtec. any sugestions on what could be wrong or what to check??? let me know. thanks for your help

hey i have the same engine as you and also have the same problem, i dont know why either, maybe just an old engine??

i get a massive burst of white smoke after i shift after vtec so, i have no clue.

-Darren-

you're burning oil it sounds like, but i don't know about u 96b18civic. what color is the smoke that comes out of your car?

MikeMAN

is ur head gasket leaking? what color is the smoke?

that info would help!

hope you find the solution!

White smoke = burning coolant, probably blown headgasket
Blue smoke = burning oil, probably poor piston ring seal or leaking valve stem seals

Black smoke = Running rich, get your car tuned with a FRP and a VAFC.

ill try to see what color. thanks for the info. i think its black though but i have air fuel guage and it doesnt look too rich on the guages ad my mods are minor so i shouldnt need it tuned for that.......should i??

yeah b19civic is correct. also does the car smoke only at high rpms??? if so your most likely running rich. with a head gasket leak and piston rings your car will smoke continuosly. I had a jrsc teg and when I took off the blower I didn't turn down the fpr enough and my car would smoke at high rpms. also check the timing of your car. make sure it's not off too much.

B19CivicHB

If your car is running rich it smells MUCH different than if it is burning oil or coolant. Rich smells like a lawnmower, almost like raw fuel. if the smoke is white, you'll smell the antifreeze.

HTH,

Oh, just hope the smoke is black and not blue or white.... the latter two arent fun to fix...

Kamin

yyep coolant smells like syrup. once you smell it you can tell it from any other smell.

i didnt think tuning was nessesary if i only have i/h/e and not much else. actually nothing else. how far off would the timing be if thats the prob? 1-3degrees or more? just wondering. thanks for the help.

btw im swapping this winter anyways but i want the motor to run strong when im done with it so i can sell. thanks yall

B19CivicHB

Timing also could affect that. Get a timing gun and check it out. Timing being off wouldnt throw a code 1 though...

93b18civic

i get no codes. jdm cluster rigged in by pervious owner that didnt hook up engine light. ill see if i can check the timing though. thanks for the suggestion

my girlfriends 94 ex had the same problem and it ended up being a blown head gasket which also fried two radiators, and it all started with a leaking water pump, so check that also. good luck.

93b18civic

ill check. thanks ttt

Jep.. my '94 D16Z6 with 142,000 miles smoking at high rpm also... see photo.. This is definately oil, as I lose about a quart every 3 days under "hard" driving. Where it is leaking into the combustion chamber from is yet to be known. (Not that I care much, the whole thing is going to be rebuilt next year).. oh also, it spits MAD BLACK CRAP out the exhaust and it stains everything. Watery sooty carbony black crap. Good luck!
