Purchased my FD back in Januaray from AllRotor93 and everything has been fantastic up until a few days ago. I started noticing that it was smoking at idle. It s not a rediculous amount but it is enough to drive me nuts. It reeks of fuel and will start to burn your eyes if you stay in the garage too long. The smoke is a greyish blue in color and again reeks of fuel. Since noticing the smoke too it has not wanted to turn over on the first try. I have been monitoring the oil level in the car since I started noticing the smoke and it has not gone down based on eyeballing the dipstick nor has the coolant level gone down. I have new plug and 10mm wires showing up next week as a first step in resolving this and from there I am going to start looking at injector/s as I believe they are the culprit.

Are there any DIYs on plug and wire replacement as they look pretty deep in there

My questions are these,
1) Is there any way to identify what capacity the current injectors are?
2) I am assuming that if the injectors are upgraded then a ECU remapping will have to follow.
3) What is the average oil consiumption per 1000 miles on an FD

The car has been midly modded with a Street Port, ported intake, ported seq turbos, downpipe,midpipe, exhaust, Apexi FC @ 12 psi,

I would also love to hear some opinions on where to go next. on the mod path.

 

1)you can have the injectors flow tested and cleaned but you have to ship them out
2)yes

you may just need a good solid tune, my car is doing this too (although I have idle problems, probably tps) and I'm gonna start with a good tune because I know mine is running rich, I have similar mods as you, only major difference is I have an FMIC, and yes, blue smoke is oil, white is coolant, black is fuel

 

If this is a recent development, the smell as well as the smoke, I would really bet you are on the right track and the plugs are just finished. FD's tend to go through leading plugs pretty fast. I change mine at every other oil change, and the trailings at every other lead plug change. My car used to do the same thing, with your eyes burning, and all I needed was new plugs and a tune. My tune was only neccessary b/c I had changed other items on the car making it run a bit richer.

The plugs by themselves are easiest to change from underneath the car. BUT since you are changing the wires too I would just pull off the elbow and TB. This makes getting to the wires and the plugs an easy task from the top of the car with it on the ground.

1) yup, as stated above, send them out and have them cleaned/tested
2) most definately
3) I dunno, but it is not really that much.

 

any updates? I did find this:
