Ok well I did a compression test and it read 150, 145, 150, 145 and I was like

so I pour alittle bit of oil on the spark plug hole and it picked up the compression to 160 + when today when I started the car it started to trow white smoke so I don't know. What do you guys think Im going to take it to the mechanic back tomorrow but I don't want him to try and give me a story about why is doing that.
