Smoke on start up and then some

Hello everyone
Drove the Porsche to Gettysburg this week after picking up car from Dawes in Strausburg the tune is finished (if one can ever make such a claim with a Motec )and the car runs strong. I have approx 300 miles on sae 30 (new engine build) and on every start the car smokes Also when accelerateing car may leave a haze which has been unsettling . Leak down numbers are between 2 and 4 percent and AFR between 12 and 13 . I plan to change oil to 20-50 and also ck oil filter this week. Any ideas that won't make me cry.

Please excuse my finger it's really not the bird ! I'm laughing to myself because I was taking a picture of my car and enjoying the fine ride but also was visiting my family's cemetery plots in Freysville Pa from the 1700 s.

I'm thinking the seals on your turbocharger.

Akita got the jump. Pull inlet and muffler to check for seepage or possible scavenge backing up?

Jon since your car is efi, it could be your cold start tune. As long as it goes away after a few minutes you should be ok. Call Dawe's to verify.

Hey John...that turbocharger is new, right? Wonder if the oil supply is properly configured (whether a restrictor is needed). Maybe give Chris a call and ask him...IIRC you bought it from him.

Until you change the thin viscosity 30 weight break in oil thats in there to 20w 50 oil and you know it's not more than halfway up the safe range on the dipstick it may smoke like you're describing.
It also depends on if new Mahle pistons and cylinders from a sealed box were installed, used ones, or JE pistons, and if they are used ones or JE what the piston to cylinder wall clearance is and are the ring lands in good condition and not worn.

Not enough information to make a good guess.. but first thing you have to do is get the thin viscosity 30 weight break in oil out and 20w 50 in and don't over fill it.
For now don't fill it above halfway on the dipstick safe range while the motor is idling at operating temperature. Only time I would fill the oil tank to the top of the safe range dipstick marks is before starting out on a long trip or before a track day if you do that.

It would be best to use non synthetic oil until the motor has at least 600 variable rpm and engine load street miles are on it so the rings seat in completely. That depends on how you drive it too. Baby it too much and rings take longer to seat.
After that 20w 50 full synthetic oil is better than non synthetic.

OK John, things don't get any better, ah? How about that cemetery/semi-bird upside down shot...? And still using that 1/2 wrinkled bra? But hey, the car is on the road and not on a trailer... BTW, don't forget to lower it some on the rear.

Seriously, WELCOME back and enjoy the car for what it is... I guess by now you really got to know and enjoy what you have there. Prrrrrrreeeeettycool car!

Lol well the bra did stop some rock dings. Thanks everyone for your replies and I will ck with Chris at Turbo Kraft for restrictor or not and as far as the Garret turbo is concerned. The rings were supplied by J E. And according to Charles at LN engineering they are Goetze rings ( basically factory) except for top ring which is total seal gapless specifically for nikalseal coated cylinder. Yes plan to change out sae 30 and ck filter also plan to run brad penn 20 50 Concerning cold starts the motec m48 has trouble idling for at least 1minute or 2 without my foot on the pedal not sure if this is typical motec

Do your turbo motor a huge favor and don't run Brad Penn oil in it. It can not handle the intense heat of a turbocharger and it will fill the motor with a coating of dirty carbon sludge even when you let the motor idle and cool down for a minute or two after running hard and change it every 2500 miles.

It is the most over rated motor oil on the planet... overrated on the forums by someone that sells it.
The old green Kendall GT1 20w 50 it's derived from was highly rated 35 years ago but Castrol GTX 20w 50 was better, cleaner running, and cost less at the same time.
...there are a lot of other people that share this opinion.

Thanks for the advice with respect to the oil. Anyone know of motec classes so I can be in more intimate with the machine ?
