Bluish smoke on startup...

Not to start another oil debate, but if you are using the pitifully thin 0W40, you may consider changing to 5 or 10W40. It appears oil is seeping past your rings or you are parking on a right/left incline.

You can certainly use a heavier base oil in Singapore, since you have no cold temperature worries.

I'm on 5W40 oil, but as the temp is over 26 degrees C all year round, including nights, I would have thought the lower oil viscosity rating is irrelevant ?

Anyway, for the smoking is only occassional, so I've gotten used to it.

I'm now alittle concerned about IMS, since this is a low mileage older car, which some post says is higher risk than a high mileage older car. Will probably do the LN Engineering bearing change at some point in time but figuring out whether it's a double row or single row bearing is a problem ! Singapore is a long way from the US, so ordering both sets and returning one could be a expensive exercise !

shlim8,

As far as the other posts about parking on a hill, left or right...well it doesn't matter. Again the engine cylinders lay flat, the oil that seeps past the rings while the engine is at rest and cooling down (pistons and cylinders shrink at different rates) is a tiny amount left in the base of the cylinder behind the piston. It's miniscule and nothing to worry about.

The optimum way to park and not have the oil seep is to park completely level, and even that won't work.

Again, enjoy your car and drive the wheels off of it. I've been to Singapore a couple of times, beautiful county and city to be driving a convertible. I've ridden the tram to see the Mir Lion. Still can't chew gum hu?

Was the car pointing uphill, and parked for a while, when the "blue smoke" incident occured? If so, it probably means nothing.
