When I start my d16z6 and rev it to 4000 rpm the minute I start it and then shut it off right away [start car , rev to 4000 then shut off , under 15 secs]
I noticed smoke in my garage , but if I would have let it run about 30 secs it would not have done this. What part of the top end that may be worn could cause this?? OR is this normal??

any help is great

Thanks
