throttle body/intake manifold

[allMTR5MGE]

on my 5mge pra i rebuild the engine and from the throttle body to the intake mani. i used silicone. after months and months i found out that i have a leak on my throttle where the silicone i used as a gasket and i was blowing white smoke smelled antifreeze. It has happened twice now im using original throttle body gasket and it still leaks? why? anyone? im out of clue i dont want to take it apart i want to know if anyone had same problem?

Sounds more like you blew the head gasket or a cracked head..I dont know if it is a regular sighn or not but when mine blew and i went to pull the motor i had coolant in the throttle body..This would be from pushing it up the intake when starting it..Othere than that i dont know..Ive been using silicone on mine and havent had any problems like that..

its weird because its not knocking and it would only smoke on starting from cold. okay i turn on the ignition in couple of seconds it would smoke thick white clouds, i turn it off and restart it again this time the smoke comes out clear white. when its running i dont feel any difference even on idle. and i dont have any antifreeze mixed with my oil.

You might have a crack in the head. When the motor gets hot the crack may seal up.

Sounds like a blown head gasket or similiar.

Think about it. Where does coolant get near a cylinder? There aren't too many places.
