White smoke

[qasimi3882]

Recently I purchased vitz 2007 1000cc. It is running perfectly good. One of my friend told me that park it in P and press the accelator in full and then observe the silensor for smoke
I did but there was no smoke. Later again one day I did same then some smoke came
It made me worried. I went to one mechnic. He open the bonnut, and had a look on engine. Then went back and tell me to push accelator. I did. But amazingly there was no smoke at all
Later he said that press it slowly slowly and increas it . Then smoke came (light and white color). He told me that ur engine is weak and need to chane.
After that i drove vitz on motorway trips (around 2000 km) but there was no engine oil or coolant decreased and car was perfect in driving. So can anybody guide me that whether engine is weak or any other problem

Some time when i press the accelator a whistle sound is coming from front.

if engine was weak blue smoke would be coming out and it would be burning engine oil! and if u revved the car full in park thandi gadi pe yeh toh khud gadi ko nuksaan poonchanay wali baat hai!

No. Not at all in morning. I tried to push full accelator then smoke came.
First time when I did this excercise. Just a dirt came,like some thing struck in exaust and now came out

After that I went to mechanic and he told me to push then nothing came. He said all is ok. Then when i insisted then he told me to press lightly and slow slow push to full..so that time white smoke came
