Alright..so..i have had so many problems with this dohc zc but its finally running for the most part..


it is smoking a bunch. White/grey smoke when i give it some gas. It doesn't seem to have any smoke as the rpms drop. The guy i bought the engine from told me new rings, rods, and bearings.

So my assumption would be that rings need to seat and it will burn oil and smoke until they seat, but im not sure on that..can anyone confirm?

I have about 225 Miles on the engine so far. Ive been making sure to keep the oil in between the dots and making sure that its not over heating or anything. How long until this smoke stops? Someone told me 1K miles for the rings to seat but IDK about that.

Figure i might as well post a picture to ***** out my car and show the kinda smoke im dealing with

Go easy on the gaytazzas...they are getting replaced after the car is running good.

Did he tell you what kind of rings he used because if he just used stock ring they should have set already it shouldent smoke for long unless he dident built the bottom end right did he gap the rings ??

and that looks like blow head gasket smoke

He didn't really say anything besides new rings rods and bearings. He said the engine would run, and it didnt because he sold it to me with a D15 crank gear on it.

new head gasket, no oil in the water/water in the oil..i think im fine there.

89GSRHATCH

i dont want to be negitive but i think he screwed you as far as the motor goes does the oil look milky at all or is it just staight oil burning are you going threw oil ??

89GSRHATCH

iam thinkin he dident know how to rebuild a motor because it should not smoke that much even for a first fire up on a brand new motor i build them for a living and they should not do that

hailchristian

it's burning oil...forsure..Ive been checking and filling constantly.

the oil is not milky at all. It goes from being clean oil. to dirty oil. Which is what its at now, dirty oil.

He said the motor had about 50K miles on it to begin with so IDK...i really have no money left and im sure as hell not going back to my d15b1 thats in the back yard.

Lets say the rings are messed up? how much would a shop charge to make everything good in the hood?

89GSRHATCH

its hard to say might be cheaper to just get another motor

89GSRHATCH

you can find dohc zc motors for around 5 550 and that well be cheaper then doing a ring job

If that smoke is as white as it looks your head gasket is toast. My old d16a6 used to do that on start up once in a while, a full year before the head gasket got bad enough to start mixing the oil and coolant...

Have you noticed any oil in your intake? Check your throttle body for oil.

Check the PCV valve if you find oil in your intake manifold


Check compression Hot, then check it warm...this will tell you alot about the rings and head gasket. A leak down test wouldnt be a bad idea too

I know it took about 100 miles for my CP rings to seal fully. It smoked that bad for only about 2 miles though then it was just light smoke when stopped I could see it and hard accel/shift.

my old pcv valve was shot. I replaced it last night.

hailchristian

im hoping its the head gasket....that would be a nice fix..compression test will bear the results.

hailchristian

Alright....finally got a compression test


results are as follows


Dry
1 160
2 160
3 160
4 160

Wet

1 170
2 160
3 160
4 170

Hmm pretty consistent. It's odd that the smoke looks so white. Are you using coolant at all?

I meant, is it going through coolant. Like do you have to keep replacing it.

hailchristian

oh...that makes more since..i was like..wtf dont all civics use coolant to cool the engines...


anywho....isnt really lowering at all..coolant level has been the same since i filled it.

so you admit you had to fill it? Im confused?

I think its a combination of the two things. The PVC will suck as much oil when faulty as bad rings will. The white smoke is definately water. Oil doesnt make that much smoke. Also your oil could be getting dirty through break-in and through burning dirty coolant from the block. I think you should check the head gasket! Did you say you already changed the head gasket or did the guy you bought it from do it? I wouldnt trust him if he says its a new gasket.

Replace the cheap stuff!

hailchristian

well..it had a leak in the cooling system..so i had to drain it to fix the lower hose then re filled and bleed..so yes

PVC was bad and replaced it so that could stop the burning oil problem..ill check into that, havn't checked my oil since the oil change.

I put the head gasket on, this was back like a week after i got the engine..didn't know what i was doing, probably messed up something. I also used a cheap auto zone gasket. I will go to the acura dealership and get a genuine this time.


thanks for all your help..ill change it this weekend and let everyone know what happens

i just checked my oil..it isn't burning nearly as much as it was with the old pcv valve.

thats good news.

zcmotor

i went into autozone and asked a worker there and he said white smoke is Coolant being burned. so doing a leak down test would tell you exactly what's causing it. I do too have the same problem and i dont want to go ahead and change the head gasket if that's not the problem. If you fix it let me know what was wrong that way ill know what could be wrong with mine

hailchristian

lol...your the same guy thats on my zcr post...

im going to an OEM head gasket this weekend..see whats going on on the block as well as replace the gasket


ill post results forsure.
