Here is the afr table I just built mostly copied from thirdgen.
I looked closer at the oil drain and i was actually leaking from the flare, I put a wrench on it and was able to get another half turn out of it. my bad. hopefully that takes care of that.
The car does smoke pretty bad though. I was hoping it would clear up, but it hasnt. There is just a little white smoke at idle, and a nice plume comes out when you rev it. Im wondering if its the turbo. I am using a 1.5mm restrictor and I did rebuild it, but... it does seem to coincide with oil pressure.
<p>Here is my 33mpg AFR table. Everything above 100kpa has been dyno tuned, just fyi, my fuel map doesn't match that above 100kpa. I don't even autotune in boost anymore, just dyno tune. You can run even leaner in cruise. Ben (@diyautotune) has mentioned before that he tunes cruise as lean as it will go without stumbling.</p><p><a href="http://imgur.com/M5ZSNhq" target="_blank"><img alt="" src="http://i.imgur.com/M5ZSNhq.png" /></a></p><p>And spark. Its a combo of some different stuff. It was dyno tuned, but changing spark didn't change power so I don't believe it is much different than whatever basemap I pulled it from.</p><p><a href="http://imgur.com/qz4RdY2" target="_blank"><img alt="" src="http://www.miataturbo.net/attachment.php?attachmentid=146484&dateline=14 39167370" /></a></p><p>Table files are attached.

This is a track only car, no care about cruise AFRs for fuel mileage. Having said that, my NA tune had me cruising around 16:1, and the NA section of your spark map is almost identical to mine. Thanks for the maps aidan.
Is there any way to rule out the turbo oil supply causing my smoking. For example, can I plug the feed, and just keep the blades from spinning just to do a quick rev test to see if the tail pipe clears up a little. Im trying to determine if this is coolant or oil. Eveything points to oil. Hell it might still be burning residual **** I guess.
You will care about cruise when you drive that thing up to Oregon to come to some awesome tracks.
<br />What does it smell like? They are pretty different smells.
<br />What seal did you forget during the turbo rebuild
So I plugged the oil feed, locked the turbine in place with a piece of wood and a vice grip and ran it for a minute. The smoking might have improved marginally. There is nothing in the charge pipes, or in the intake itself, all clean as new.
so I pulled the plugs, theyre covered in oil. Keep in mind this is about 20 minutes run time total on these plugs. 1-4 from left to right, you can see where I just wiped the oil off of 1 and 4. So I think this rules the turbo out, at least as the only cause as it might be contributing.
So my intake valves are leaking is my best guess. They are new. Guess I should go pull the VC? Or should I just go flog it and see what happens?
I looked down the spark plug holes, all 4 pistons has a small puddle on it
Stem seals are the only thing that can cause this to my knowledge. Its like theyre not even there. Im confused how new stem seals can all fail so bad like this? Can you really **** up seal install that bad? I handed the seals that came in the felpro kit to my machinists, so its possible a mistake was made. Interestingly the part number on the head gasket kit for the stem seals isnt the same part number that comes up if you buy the seal separately from felpro. Felrpo doesnt even recognize the kit part number.
Any insight before I order seals and a valve spring/keeper tool? Is there a stupid plug or something I forgot to install? I would really like an easy button. This has me upset so im going to go play world of tanks for a few hours.
I wonder if maybe they were installed dry and tore or rolled up or something, like you said I don't see a lot of room to mess up the install.
The only other thing I can think of is they didn't get pressed down onto the valve guide thing far enough and the spring bucket trashed the top of em, ripped the oil seal spring out? I hope not, those would be a bitch to find.
