I just put in some lower compression pistons did my valve seal and put on a turbo kit and my car smokes when I first start it. I know that usually its the valve seals but I did them. I don't know if it smokes at full throttle because the motor is not broken in yet. Before I did this rebuild my car smoked under high vacuum but the weird thing was that it smoked on all 4 cylinders. Does anyone have any suggestion on what it could be.

 

You will get smoke for a while man. Gotta give the rings a chance to seal.

Which break-in method will you use?? ride it like a virgin till it's broken in or ride it like you stole it??

My crx was doing the same thing, when you just turn the car on and let it idle till it warms up you see smoke from the exhaust.

Now it's being about a little over 1k miles on the new build and its cool. Started to use Mobil 1 syn again and the car runs smooth very smooth.

 

break it in.....that's all!!! enuff said!!!

do oil change(no syntetic oil) at about 500miles and 1500-2000miles next oil change and after that another one at 2000K. after that do the regular 3K oil change and use syntetic if you want....

 

I've build a few motors now and they've never done this. I'll take your advice and wait I hope that your right. I'm breaking it in pretty easy I had to make a couple hard pulls to see where the afr's were at but now i'm going to take it easy for a 1000 or so miles.

 

Still puffs I've put on 600 miles nothing seems to be different. It just does it at start up and I don't seem to be much oil.

 

hmmm...do a compression check.
