hey guys i have a buddy of mine who is a mechanic and owns an 90 gt.After taking just the throttle body off and putting it back on there was white smoke coming from the exhaust. Sounds like coolant in the system, so after taking the whole top end of the moter off and putting brand new gaskets and seals everywhere there is still white smoke coming from the exhaust. now just from taking the throttle body off then putting it back on,how is coolant being burned up in the engine?
