hey h-t members..
i just bought a crx...and white smoke comes out of the exhaust...i just changed the headgasket,timing belt,waterpump,and headstuds..the old headgasket was blown..i thought everything was good until i started it up...white smoke still comes out of the exhaust...i thought it was the gasket so like i said...i changed it..but the same thing still happens...DO YOU KNOW WHAT THE PROBLEM IS? is it a bad cat?
thanks....

 

Have you ran it long enough and hard enough to clean out the ehxaust system?

i left it running for about 10mins..and drove it around for like 10mins..i ran it 2 times within that 10mins...how long should i run it for and how hard?

 

any more thoughts?

 

Cracked or warped block or head ... did you have them checked before your replaced the head gasket?

 

yea the block and head was checked...everything was fine when the headgasket was placed on. do you think it might be the cat?
im running a sohc zc and a ls ecu...do you think its the ecu?

 

Is you Honda running nice and smooth? If so dive it normal for at least 30 minutes or till it stops..

Bad cats meow and hiss they do not smoke and 10 minutes is NOT enough time for a coolant saturated exhaust system to burn off.


Good luck

 

the motor is running great. the only thing is the smoke...ill try driving it for 30mins and see whats up..thanks

 

i just drove it for about 45mins...still the same...any other suggestions?

 

Sea foam took my smoke problem from my Rex...10 bucks at like autozone...smells like crap and smokes like a firework...but drive it hard for like 5 minutes...smoke was gone and ran cleaner...

 

thanks...ill go buy it and see wassup...rite now its smoking like a firework too.haha..thanks bro

 

with the sea foam...am i suppose to spray it into the manifold?

 

Bummer...
How does your oil look?
I would start pulling spark plugs to see if there is signs of coolant.

What are you burning coolant or oil?

Seafoam is good stuff, its used to clean the carbon in your cumbustion chambers as you feed it through a vacum line in small amounts, so as not to hydrolock the motor.
I guessing it wont help in your case since you had the head done...

good luck

 

"Seafoam is good stuff, its used to clean the carbon in your cumbustion chambers as you feed it through a vacum line in small amounts"...Amen...not manifold...in the vaccum line...works better with two people to keep the idle up...

the oil looks good..nothing is wrong with the motor..it just smokes alot out of the exhaust. it was the coolant but since i changed the headgasket.. iono what else it can possible be.


seafoam is probably cheap anyways...so ill just pick that up and see wassup

 

Did the sea foam work for you?

 

I'm having the exact same problem with my CRX. It's got a brand new rebuilt B18A motor, so I'm clueless as to what the problem could be as well. Keep updates and I'll do the same if anything is found out.

 

i just used the sea foam yesterday..but nothing..still cant figure out what the problem is...ill try calling my uncle and see what he think it might be..ill keep the update...

hey hondanoob

i figured out what the problem was...its my piston rings...before you do anything...get a compression test to see which one it is...

 

I already did one, but the manual I have with the compression numbers apparently was the wrong one. And I guess hondas hold compression differently then my old VW does. So what were the numbers you got? I had 150 on plugs 1 and 2, and 170 on 3 and 4.
