Any mechanics out there?

[Atypical]

Recently bought a motor, the coolant drains from the Over flow reservoir within three days, but the radiator is full, I've had a pressure test done no leaks, no sweet smell from exhaust a little white smoke on a cold start and some drops on ground but disappears when car warmed up. Car doesn't over heat.

Any ideas?

Just in case it's relevant- It did lose a a little power going up a hill one day and it over revs on ignition to 1500 rpm, but drops to normal 800 when driving and idle in traffic

From the expansion tank?

Higher revving is normal on cold start until warmer

Yes.

Sounds like the expansion tank?

It is the expansion tank, it has the low high level it is bone dry.

What vehicle? Temperature guage levels?

Have you tried taking the cap off and starting the engine to see if any water pisses out under pressure?

Check oil cap for MAYO and dipstick

No gunk on oil cap no creamy appearance, level of oil ok, temperature fine.
