My first post but been member awhile. Im sure this has been asked to death but i have 3 o3 early 04s that vent from degas. all have passed the vac portion of tsb and none of the cust have approved cooler removal for off the veh testing. Well now one is my own 03 with 182k. Whats strange is it only seems to happen hot and light to medium loads. have done many wide open accels and not had it vent. My personal cooler temp differance of max 8 degrees. Before I tear down has anyone seen cooler do this or am I most likely going to be pulling heads.
Thanks.
Ray.
