Blowing white smoke when reved up.... boggs a little when accelerating, idles a little rough also.. its a 93 civic dx with a 1.5l
White smoke is usually caused by a cracked head gasket or cracked head, but some times it is caused by your brake booster sucking brake fluid into the intake through the vacuum hose. If your brakes are constantly going soft, or your brake reservoir constantly needs refilling then that will be your problem. Replacement will include both the brake booster and the master cylinder.
If the cause is a leaking head, you can fix it with sodium silicate (liquid Glass) which can be purchased in most pharmacies. You will need to remove your thermostat to keep it from sticking shut before doing this. Replace it after the smoke is gone.
Remember that the sodium silicate trick is more of a bandaid than a permanent fix. Also remember that sodium silicate is not a good fix for steel heads, and since yours is aluminum it should work.
BUT since your problem only occurs as you accelerate, I would suspect the brake booster and master cylinder.
