my rb started to smoke but only smokes when i rev it (but only does it the first time that i rev if i rev again it wont throw any smoke).also when im driving it doesnt trow any smoke .btw the smoke smells like gas but its kind of white bluish
also i have few more question
my ecu have 2 led lights one green and the other one red .when i turn off the car these 2 lights stay on .when i turn on the car the green lights flahes ,is this normal .

thanks guys

uhhhhh that doesnt sound normal to me.. Anyone?

I don't know anything about the ecu codes. Typically the white smoke is coolant leaking into the engine and blue smoke is oil. Both could be because of bad gaskets and seals. When you rev the engine it probably builds up more pressure which causes those seals to leak more than under low load. It could be more prone to do this when it's cold because those seals might expand a bit when it gets hotter?

I'm just making a guess to help spark some ideas.

im just concern about the ecu .i turn off the car and they stay on am afraid its gonna kill my battery

Can you plug it up and get a diagnostics run on the ECU to see what's causing those lights? I would have those same concerns about the lights. The drain is probably really small, but you never know.

how come you do not check for codes from the ecu. I agree with Radianation some leak. that light will not kill your battery lol. check for codes!!!

when i first did the swap the idle wouldnt go down.i removed the acc valve and the gasket broke .i couldnt find the gasket anywhere and i just put silicone gasket ,would this be the problem my idle its fine well sometime when i boost and brake hard my car tries to stall.thanks guys
also theres no oil in radiator and sometimes i can smell a lot of gas

also i tried to check for codes and both lights blink at the same time

I'm not sure exactly why there would be oil in your radiator?

Oil in radiator is usually a BHG.

Pull each plug one at a time and see what the end electrode, insulator, and the ground strap look like. See if there is oil on any of them... If so do a compression check to check the piston rings and also to see if the valves are properly seating, If that looks good then I would put my money on a set of valve seals... Post some pics of your plugs if you can, maybe I can help point you in the right direction.
