Hi to everyone, 1st timer on this site looking for some help. I'm running a Defender 90 300 TDi 1996 105,000k on the clock. Over the last week or so, I am experiencing lots of white'ish smoke with tints of blue streaming from the exhaust, on changing gear, accelerating off and on stand still. This only occurs once the engine has reached full running temp, up until then it performs as normal with no signs of smoke. Puff of black smoke on start up. Can anyone shed some light on this matter. Regards Karl
