I just put a Sir II motor in my 95 civic ex. IT runs fine when it just sitting there but after a minute of driving white smoke comes pouring out the back. It doesn't smell like oil or coolant. (i think) and the car is really sluggish. I also know the timing is off. Could that be the problem? Someone told me it cold be running rich. Thanks for the help
 
yep, i'm gonna say headgasket issue. the white smoke you see is coolant going through your exhaust. watch your temp guage carefully. if its a headgasket problem it wouldn't be really hard to fix, but if you just bought the motor and you just put it in, there could be other problems your not aware of.
 
if i were your i would do a leakdown test, if it is white smoke it is more than likely oil burning. you may have bad rings or you may need to lapp your valves so they seat properly. but most definatly adjust your timing.
 
ummm no

blueish smoke = oil
white smoke = coolant
black smoke = running rich or excessive carbon deposits
