I am running the stock 154K mile bottom end. I have noticed that my car burns more and more oil. Not only do I have to add a quart every 1,000 miles or so but it smokes out the exaust. It used to only do this when cold, but I noticed it doing this when hot also. It lets off alot more smoke when getting on it now than it used to. I know the PCV is overwhelmed because I am getting oil all in the intake. I am guessing piston ring blowbye. I know this will only get worse. Should I start saving to rebuild the bottom end?
