1st check for any cross contamination of the coolant and oil. (ie ? headgasket)

2nd Replace the radiator cap, if they fail your just blowing coolant out. See if that does it.

If not then check and/or replace your thermostat and flush.



PS: maybe no caps on post........

Also, use a lower gear, higher revs and less boost.

Flush the cooling system. Use distilled water from the grocery store to top-up the coolant, and use a mix of 30% antifreeze in the summer- one jug of pre-mix and topped with distilled will work out fine. Don't use your well water for it.
