Car started poofing blue smoke after driving on freeway and a cold restart. Only under these conditions. Tried to have it fixed, repair guy said oil had leaked on engine. Attempt at fixing made it worse with an enormous cloud of smoke coming from exhaust pipe.

found out about the problem when having my oil changed. was told to make sure to keep oil at correct level between changes. Have not had the covers changed yet.

Acrid burning oil smell from under the hood, which even gets inside the cabin when stopped at a traffic light. It's the rear cylinder bank valve cover gasket that is the culprit. The oil doesn't drip onto the ground - it just gets burned up on the rear exhaust manifold. It's a bit of a bear due to the way Toyota mounted the V6 engine, with the front cylinders almost vertical and the rear cylinders almost horizontal - the rear valve cover is close to the firewall. 1MZ is still a great motor, though!

Oil leaking on driveway and burning smell after driving approximately 5 minutes. Had repaired (replaced both valve cover gaskets) at dealer for $692.

Bought it used; front gasket had been replaced[or was claimed to have been]but not rear gasket. The burning smell is most evident on cold days when heater is bringing hot air from under the hood, after the car has been driven first time in a given day, fully warmed and then is stationary but engine and heater are still running. Heater blower then carries smell into car
for a short time.
Have not had it repaired; too many other items on car needed to be replaced...all brakes, full exhaust system[CC included], and tomorrow front struts are being replaced.
