Hi all,
My wife’s 740 (B200E) tends to have a bit of a splattery discharge of water from the exhaust from time to time. Usually when it’s cold, but occasionally when it’s been running in the drive warming up and is up to temp.
It doesn’t loose coolant, runs very well and, whilst a bit crotchety with regard to cold starting (always fires up but is a bit lumpy/flat for the first ten seconds or so) is always reliable. No clouds of steam, bubbles in the header tank or mayonnaise in the rocker cover to indicate HG issues, and the water from the exhaust isn’t coolant (yes, I tasted some on my finger to check…don’t judge me!
)
What could this be? Just condensation? The exhaust is past it and the back box has some minor perforation, to be replaced soon when we can afford it.
It’s a pre-Cat car. I’m not worried, just curious. Any ideas?
