oil burning

[twolo4u2c2]

I have an oil burning problem but this one is a little different. I pulled all the plugs and the pass side are all black with oil and the drivers side is normal light brown. The burning is mostly at idle and is clean when revved and kept at 3000 rpms or so. as the reves come down the blue smoke slowly starts again. The problem slowly started happening....any ideas? please help.

thanks

have you tried an MMO soak? I had a 96 Saturn that burned oil, did an MMO soak overnight and it cleared up the problem. I was burning 1qt/3000 miles
