998 A+ stage 2 recently rebuilt engine (was originally an 850) on remote change gearbox which was also rebuilt with a 3.44 ratio. 1973 Authi Mini (built in Spain).
I'm suffering from an oil leak under the driverside (LHD) driveshaft, but cannot assure it's the driveshaft the source or if oil drops just fall down from there. I'm having this leak since the engine was rebuilt in January although did not pay much attention to it at first as it used to come and go with the wind. It is a bit of annoying now and finally I've noticed WHEN it happens but don't know the WHY:
I start the engine and if I keep it just on idle without any push on the gas pedal for the first 5 minutes or so until it is hotter, there is almost no leak. What is more, it stops a bigger previous leaking when I follow this "soft" procedure.
On the contrary, if I put a bit of gas on the pedal soon after the start when it is cold to rev the engine a bit (no more than 2,500-3000 for sure), the leak is much much bigger and do not stop nor reduce even after weeks without touching the car. It remains leaking the same forever and ever...
All above is the same wether I drive the car of leave it in place without moving the wheels.
Any idea? Looks like any gasket is suffering from pressure at cold temp, remaining "open" until I gently warm the engine again...
Thanks in advance
PD: Oil is Millers 20w50
