Bluish smoke on startup

[sadil]

Hey guys, I have noticed that the engine starts up with some bluish smoke nowadays. I leave the car oitside because of garage work and there is a lot of rain with temps between 5 and 15 degs celcius throughout the day. Car has LTs and no cats. Any opinions? After the initial start, it returns to faint clear smoke. Any ideas?

Do you have an oil car can? Perhaps oil in the intake burning off? Noticed oil consumption?

Yeah I have a JLT oil catch can. The car has been sitting on the driveway on a decline so maybe all the oil is collecting in the intake and being burned off differently due to the angle?

How many miles are on the car?? Usually blue smoke on start up is a good sign valve guides are loose.

Is you catch can full?? Either way try emptying it and see what happens...

I have 26000 kms on the car. Valve guides? That doesn't sound good does it... I gotta check the catch can.

Catch can was a third full, still getting blue smoke on start up. I have never used the car during sub 10C weather with the upgraded exhaust (O/R X and LTs) so it might have been that the cats were absorbing the oil? Im thinking of getting a drivers side oil catch can as well, JLT supposedly has a new design that catches more oil. Also saw that my coolant was below the fill range , I dont know if this is cause for concern since I have never touched the coolant since I bought the car, how fast does the stuff leave evaporate during normal operation?
