  1. Thanks for your quick welcoming answer JFP! Ouch! I'll try to get it pressure tested then. Thanks Alex
  2. Hi All I suspect my 98 Boxster 2.5 has a cracked head or blown gasket but was hoping you could confirm (or suggest otherwise!!!! ) based on my symptoms: -Occasional white smoke on cold start (quite a bit) -Expansion tank appears to be under a lot of pressure (cap hissing, even the new xxx04 one) -As soon as I rev above 3K, expansion tank pressurises big time, coolant level lowers and low level light flashes. When I stop the car to (carefully) release pressure at the cap, white exhaust fumes come out of tank (smells of gasoline) and coolant level raises back again. To me the instant compressing at high revs is the giveaway as the warning light follows within seconds, and it appears to fill the cooling system with a pocket of fumes. The crack however must be small because everything is normal if I keep the revs below 3K, even after a 30min drive. The tank does seem under a lot of pressure though, and the manual bleeder valve will sometimes stay up after several days until I remove the cap to release the pressure... I tried burping the car multiple times, and replaced the cap with the 04" version. Could the above point to anything else? Thanks Alex
