Smoke out of the tailpipe? You sure you don't have a "banana in the tailpipe" like Edie Murphy did to the cops in Beverly Hills Cop? Just joking.
The standard answer is valve stem oil seals, those little caps at the base of each valve that stop oil getting through from the top of the cylinder head into the chambers. Apparently that causes blue smoke, but only when the car takes off from a stationary point, as it has then had time for the oil to soak down into the chambers. When driving, less can get in as the oil is moving around all the time.
You can change the valve stem oil seals with an Overhead Spring Compressor tool but get one that costs over $50 from eBay. There's some cheaper ones that don't work well if at all. With it, you need a spark plug attachment to plug an air compressor hose into each cylinder as you do it. With air pressure on each chamber, the valve won't be able to slip down into the head itself. If that happens, you will definitely have to remove the entire cylinder head to retrieve and refit the valve (remember that the springs of each valve have to come off to change the oil seals on them, so nothing is holding that valve in place except the compressed air you pump into its chamber). With this method, you don't need to remove the cylinder head at all to change the oil seals on it.
So what has caused the Piston Rings and Valve Stem Oil Seals to deteriorate?
Is it just Engine Life now too short, is it wrong type of oil, wrong type of fuel?
Ive been using E10 as my fuel and once have alternated between that
Ive also been use 15W-40 as my oil.
If I can find out what has caused this to deteriorate then i know how to prevent this from reoccuring in the future.
