Hey, just bought a 1980 b310 sunny with an A12 and it is blowing blue-ish smoke. Only when revved quite a bit.

Car had been sitting for about 8 years prior to me buying it.

Im assuming burning oil, since it smells quite nasty.

Is a compression test the first step i should take? and if that is okay where do i go from there?

Also, are there any preventative things i should do to the car since it has been sitting such a long time?

ANY help is very much appreciated. Thanks
