Well first of all its a 94 Ls motor in my hatch. Well today while driving for about 20 minutes, white smoke all of a sudden starts billowing out of my exhaust, now to the point, the engine is not and has not been overheating at all. It idles good starts up fine and everything. while idleing it really doesnt blow smoke until i rev it up. i checked the oil to make sure their was plenty and their is, i've always been told if the oil is milky looking or smells like antifreeze then more than likely its a blown head gasket, but the oil looks like neither, it looks normal. Plz guys i need some help on maybe what it might be and some ways to test and check to see if thats it. I just wanted to see if it might be something i can test somewhat easily before i take the head off to see if its the head gasket, thanks guys.

 

i woul dhave to agree with you on the headgasket

 

im blowing smoke too
1st do a compression test
its simple

then try a leak down test
im taking mine to a shop for a leak down tomorrow

hope that helps

 

Ok first of all thanks guys for the help. Can i do a compression test myself? If so how? and whats an average price on having a leakdown test done? sorry for all of the questions but this is making me sick, lol. thanks again for the help its greatly appreciated.

 

ok for a compression test u need the tester
i hear its only klike 20 dollers
i borrowed from a freind
heres a link how to do it
http://www.c-speedracing.com/howto.php
scroll down for it


for a leak down i hear its like 50 to 75 dollers for a mechanic to do it

believe me i know exactly how you feel
im in the exact same boat as you

best of luck to you

 

could be rings right?....i dunno i had a hb and it needed rings and when you get on it it smokes...in higher revs..peace

 

redline201- Thanks for all of the info and the link, and best of luck to you also. Would you by any chance know how to check and see if the rings are bad? thanks again man.

Fuzion- Do you know of a way to check and see if the rings are bad? thanks

 

White smoke is deffinately burning coolant. Do a compression/leak down test and take a look at your numbers. If one or more are unreasonably low, then bam, your problem will most likely be shot rings. If not, then check your headgasket. Your oil wont be very milky unless you have a fairly large leak which it doesn't seem like you have. But in the mean time, keep an eye on your oil and coolant levels to make sure everything is ok until you get the problem taken care of .

 

EVIL_EKology- Thanks for the help man.

And thank you everybody else again, you guys are lifesavers! Anybody know the best place to pick up one of those compression tester gauge things? thanks

No problemo amigo. For the compression tester...check your local parts store (i.c Kragen, PepBoys, etc.) if they don't have any I guess you could stop by a shop and have them do it for you really quick. It shouldn't take very long for a compression test, I would say 20-30 mins MAX. Good luck man!

 

Thanks once again EVIL_EKology

 

Once u get the the compresion and leakdown checked out ..let us know the results

 

i found a kink in my oil return line

i think thats the culprit

how my snail aint toast

 

I had the same problem last week!!! if that does not fix your problem... check your spark plug wires to see if oil is in there and if it is change your valve cover and sparkplug gaskets... $23 bucks out the door from honda. also doesthe white smoke burn off? i thought i had a blown headgasket....

 

is your water///antifreeze burning? if your car isnt over heating burning water///antifreeze then its prolly not a head gasket cause head gasket will make your car overheat all the time.....So i've heard...

 

it could be a cracked head/wall or a blown headgasket. go to google and look up "Steel Seal". **** works really well. fixes blow headgaskets and cracked/warped heads.

 

While checking the compression we bumped the first 2 cylinders up to 150 and held it their to see if they'd leak back down, and they didnt. We didnt get to check the other 2 because my friends son broke our gauge. The spark plugs were fouled, I had to put the plugs back in their so i could make it to work and the car ran fine and didnt smoke until i get on it, but if i drive the car normally its fine, but when i get on it for a few seconds it starts to smoke, i've noticed to the exhuast fumes are smelling like gas, so its running rich right? but i dont know why. Any more adivce guys? thanks

 

My car does the same ..blows out alil smoke out the back at high rpm's actually only when get near redline..im guessing im running rich cause of the skunk2 p28 ... but when i get time imma get a compression check also... keep us updated when u check the other cyl for compression.

 

i have Mugen ECU fitted to my DC2, when I change from 2nd gear to 3rd at about 8500rpm lots of white smoke came out, but it won't happen to 3rd to 4th gear. Can somebody tell me what happen?? I try my OEM ECU, no white smoke, so is it the ECU or my car?? thanks

 

Everyone says if your blowing white smoke to do a leakdown test. Obviously if you have a blown head gasket, it will leak air. Well what if it doesnt leak air in or out and yet your still blowing white smoke? Leakdown tests were solid. At 50psi, it held 49psi. I went one step further and did a coolant system pressure test. At 30psi, double the factory spec, no pressure loss after 5 minutes or leaking coolant! I tapped a cotton swab to a screwdriver and swabbed the top of the pistons and they were all dry! Yet I still blow out alot of white smoke.

Leakdown results: &lt;2%, every cyl
Compression: 190psi, every cyl
Coolant Pressure test: 30psi, no pressure loss, no coolant in cyl
