blows blue and white smoke out the4 tail pipe. Can i fix this with some kind of engine block sealer....

The blue is oil, the white is likely coolant.  If it's that bad that it's happening all the time, no engine block sealer is going to fix it.  You may be in for a head gasket.

blue and white at the same time??? sounds fishy...does the blue pulse first then the white, or does the white come first...oh I know, you have dual exhaust and the white comes out the left side and the blue out the right side....either way it's a 17 year old acura...scrap the p.o.s. ...get your $30.00 scrap money and buy one that is not smokin pretty colors out the rear...hope this helps...

You need to have your injectors adjusted.  They're running too rich.  Take it to the dealer.

head gasket

Head gasket. Rich fuel would be black smoke. You don't want to drive it when it's doing that, you get oil in your coolant, but that's not really the worst. You're getting coolant into your oil and cylinders. That is not good, the reasons should be obvious.

definitely head gasket.

White Smoke = Coolent
Blue Smoke = Oil
BLACK SMOKE = FUEL

His problem has nothing to do with fuel.

If it looks like milk shake in your radiator. Then drink it.

most definatly head gasket!! mines excactly the same, bugger to do the head gasket, but if u think its worth it then get it fixed. u should get away with block weld for abit though. good luck : )
