Ill start off by saying im just looking for advice not people chewing me out about doing my research before asking questions. Im also going to throw a lot of information out in this first post and I am going to appologize in advance if things may seem unclear.

I have a B16a (stock internals) with a B16a PR3 head, This is my first rebuild and of course i am running into problems, lol
The engine started fine when I got finished building it and putting everything together, nothing out of the ordinary. I drove it around for a while with no problems, didn't beat on it at all till after 150 miles and an oil change, the only time I "beat" on it was hitting vtec once or twice but that was it.
After the oil change i noticed there was some smoke coming from my exhaust, not much but enough to question, i was told maybe it was cylinder wash because of a bad tune. I decided just to keep an eye on it and the oil level. I noticed a week later that more and more smoke appeared so i began to worry and stopped driving it.

The problem is that I am burning oil, I know this because there is white smoke coming out of my exhaust pipe and when I wipe the muffler pipe it is a liquid as opposed to a powder form. So to investigate a little further I took off my exhaust manifold and looked inside the exhasut ports and I then learned that pistons 1-2-3 are all burning fairly clean but piston 4 is where the oil is coming from.

Now after learning this i went and did some research and came upon 3 possibilities for a solution
1) Head gasket is blown, deformed, defected ect
2) The valve guides and valves could be loose due to them being old ect.
3) The piston rings


I have replaced the head gasket (OEM) and I actually had the head rebuilt, (New valves, stems, and guides) the head was also resurfaced. I put everything back together and it was still smoking. One random thought one day was maybe it could possibly be my valve clearance for some reason, So i re did the valve clearence and it semi fixed the problem, i noticed a lot less smoke in idle, but the second you open the throttle a little bit, here comes the smoke. (Keep in mind this is my first rebuild so i could possibly be doing the valve clearence wrong still.)


Now my question to anybody out there, Is there anything else I should investigate on this situation before i jump into replacing the piston rings. I have no issue replacing them, but why spend the time and money in replacing them when it could be something totally different or unnecessary?

I want to thank anybody ahead of time that took the time to read this and help me out. Thanks

 

do you get smoke under accleration for or under when letting off the throttle?

 

Mainly when its under acceleration, but it still smokes in idle

 

After coming across some other forums I have more information to add.

I have learned that a light grey/ blueish smoke is oil
and a white smoke is coolant (from head gasket)

After i learned that i turned my car on again and looked at the smoke from a different angle and lighting to see the true colors, and i see both

Blue smoke when it is idleing, and white smoke when the throttle is opened

Now i still find it hard to believe that it is the head gasket, because i have gone through like 4 of them both oem and the fel pro ones

Is there any other place that i could be leaking coolant or oil into the cylinders?

 

Are you losing oil or coolant? If so, how fast- how often do you need to refill? You should check the #4 plug wire just to be sure.

 

I don't drive it so i haven't noticed if i am losing much, and yeah ill check the plug and plug wire today

If what i have read on other threads about the color of the smoke was correct then theoretically I would be losing oil and coolant..

 

Ended up being a busted oil ring
Thanks for the help anyways
