This is the second ITR motor that I've had. The first one was a 98 ITR original vehicle and motor. This one is an JDM ITR swap. Both motor are below 70k miles and both had the same smoking problem. Just wondering if this is normal or is there something wrong.

My problem is only during the colder seasons like between fall through spring. If I drive my car normal it'll smoke.

This happens when i drive it normal on the hwy at 70mph with my foot off the gas pedal while its still in 5th gear, and the speed is dropping back to 60mph. Then when I gas the car, i'll see a puff of whiteish/blue smoke coming out. This only happens on colder days, and it stops happening after the car is driven for more then 1hour. But even if the cars at normal tempature it'll still do it unless its after an hour or so.

Anyone know what this could be? Or what could be causing it to do that?
