1997 Civic HB

So i did a mini me swap to my car a month ago and the car smoked when vtec kicked in so i have rarely hit vtec. now today i received my new header in the mail.

ever since i did the swap the car did not smoke unless you hit vtec. and the car wasnt smoking today. so i installed the new header, just to see what it sounds like with just header on i fired it up and punched it (DAMN THATS LOUD!) and no smoke unless i hit vtec.

so i go to connect up the rest of my exhaust (no cat now) and the header was 2.5" and my stock exhaust didnt match up, so i got them connected eventually and no exhaust leak from the connection.

NOW the car smokes even at 2k. WTF could have caused this? and it smells like oil burning.

also for some odd reason my oil is 1 qt over now when yesterday it was even. could it being a qt over cause smoking?

 

Yes, it will burn it off.

But I suggest draining out a quart instead of burning off a quart.

but would it burn off that bad that it would start smoking at 2k? i just want to make sure...

 

?

 

??

 

yes, it would look like you were in spy hunter and hit the smoke screen button.

hahaha awesome

 

also the cat gets rid of some of the smoke. but you dont even have it now soo.

 

Perhaps you had some leaky valvestem seals or worn pistons/rings that were noit smoking too badly until you gave it full throttle a few times to test the header out, so now they've gotten worse.

A header in itself should not cause any excessive smoking from the tailpipe.

What COLOR is the smoke?

 

smoke out of the tail pipe or out of your engine bay?

During install the grease from your hands can get on the header and when it gets hot, it smokes. Very common.

its a grayish smoke, and i know that the some valve seals are bad and when i tested out the header i only revved it to maybe 6k

but im going to drain some oil today to see if it fixes it. i tihnk i just may change it and go back to conventional or synth blend

 

Spy Hunter is the ****! anyone ever get super far in that game?

 

well i drained all the oil and replaced it with conventional oil and back to 5w30 and most of the smoking problem is gone. just a little bit left over and even when hitting vtec it doesnt smoke as bad

 

You're welcome.

thanks! i guess switching back to conventional helped. i was running 5w20 full synth

 

I don't think it was the synthetic; but the extra quart.

i know but wouldnt the synth cause it to leak more because when i had no real smoking issue i had full and it smoked like it was then it was a qt over than that is where this issue happened and now i went back to conventional and its not as bad

 

BTW:

Exacyly how much oil are you putting in your engine? It should really only be about 3.5 quarts with an oil and filter change.

 

3.4 qts as i am using the Y7 pan. i maybe swtiching to the Y8 pan so it would be 3.7
