ok heres a sum of all my problemswhen i first got my car it had a good puttering sound, ran real weak, and idled at 400, and smoked horribly

then i replaced the spark plugs, did wonders got my power, normal idle, and the smoke calmed down alot

i still smoke though only when i accelerate and my new plugs quickly built a small layer of carbon so I guess im running rich

and it also looks like im leaking oil directly out around the third cylinder, ill post a pic if need be

ive only had a chance to get compression test of the first cylinder which came out to 125, havent had time to check for cylinder consistency

any idea what i could do to help it out a little?

you need to indeed verify that you are leaking oil around cyl. #3 and if so, you may be in for an exploratory tear-down. Your compression is quite low on an otherwise stock engine. Engines that were beat down in Japan usually posess these characteristics.
