OIL In Cyl #3 - SparkPlugs Coverred - Smokes A Little, Need Diagnosis
 

This is a brand new rebuilt d16a6 motor, total bottom end is 100% new with new parts, the head is completely built and was previously used for 4500 miles and then slapped on my motor.
The car ran great for the first 3K or so Ive had it and just recently I noticed that after the car is fully warmed up and you go for a drive. Come to a stop or slow down hard, the car will kind of billow smoke. Not to heavy but enough to surround the car and into the cabin a bit.
Smelt like burning oil so I pulled the plugs, sure enough #3 was SOAKED, a good 1/2 teaspoon all up the threads and on the tip of the plug.

I did some research and found that the valve cover gromets like to fail on people, picked up a brand new set and threw em in, didnt work.

Now this problem doesnt seem to be constant, the car has gone a day before without smoking, but today it smoked at almost every full stop.

It will not smoke if you start the car up from cold and let it idle, no smoke at all.

Im lost on what it could be or how I could fix it.

if your burning oil it doesnt matter what kind it is,
start with a compresin test of all four cylenders and see if one (#3) is lower
if it is try putting some oil in the cylender then recheck it, if it goes up your rings are gone
it could be a lot of things but start with that

Well Theres oil on the dam threads of the spark plug, to me that mens its coming from the top.... right?

I did just replace the valve cover orings though so I cant see that being the problem, would teflon do anything there or would it just burn up?

if new seals didnt change it dont try it have assed and hope for a better result, do the compresion test, if it was getting from above your plugs to the cylender where its burning your plug would of blown out

unless you have a seriously fucked up head, and the spark plug hole gromets on the valve cover are good, then it's not coming from there. do what everyone else has told you and do a compression/leakdown test and work from there
