My dads 2000 bonneville SE is, eating a little coolant, exhaust is a little white and smells sweet, and i can see a little smoke off the front 2 cylinders to the drivers side of the car.
temps seem fine, powers a bit down. i personally want to repair it, he wants to wait a month to get a new car. the sweet smell+exhaust smoke has been there for about 4 months, the smoke off the cyliders just happened 2 days ago.
just curious once these things start to leak, how quickly do they just give out?
Its been runnin dexcool since day 1, had a rad flush at 40000km and dexcool put back in by the dealer, cars at 160000km.

Re: How long with leaky LIM gaskets?
It could just seep for a long time, or it could fail at any time. IMO, fix it ASAP before it dumps a bunch of coolant in and either hydrolocks a cylinder or it gets into the oil and wipes out some bearings.

If it's in the oil you will get the famous "milkshake" look when you open the oil cap along with some froth.

It's either the LIM gaskets or the upper plenum itself leaking.
