Hello all, I've had my liberty for about 6 months now and it is a great vehicle that I love. Recently it seems that after the vehicle is warm and I let it sit for about an hour and then get back in to go it seems to have an issue. It doesn't smoke on start up, but once I get out of the driveway it seems to run rough and then I get a big cloud of blueish white smoke and then the engine will smooth out after aboit 10 seconds and the smoke will disappear. I'm starting to think possible warn rockers? Although I have no idea if that would be the cause, I only say so because runs rough for those few short moments. I know I'm also due for a timing belt change etc. Never does it any other time that what ive just stated. Vehicle gets used on highway with mostly highway driving and very little city driving.
My vehicle has 165,000km or about 100k miles. Other than that it runs perfect, starts no problem when cold, doesn't smoke what so ever other than a little bit of black smoke if I floor it. No other odd sounds that I can pick up over the diesel clatter.

Are you loosing any antifreeze/coolant level out of the coolant reservoir tank on the firewall?
White smoke generally can indicate a head gasket leaking.
You can do a simple test. After letting it set overnight, remove the coolant reservoir tank cap to ensure there is no pressure in the coolant system.
Reinstall the coolant reservoir tank cap, start the engine, run it for about one full minute and then shut it down.
Immediately remove the coolant reservoir tank cap slowly and listen for any pressure escaping.
If you hear pressure escaping, your head gasket is leaking or you possible have a cracked head.
Also, if you see bubbles coming out of the coolant liquid when you first start the engine cold, that is sign that your are getting compression pumped into the coolant aka head gasket leak or cracked head.
There is also combustion leak detector for coolant available at the parts stores and on line.
