Hi all, my 1JZ's inlet manifold has one hot spot when the rest is cold.. is this normal?
In the spot marked "source of heat" theres a line that can be seen running into it, which runs down into the side of the block, but this doesn't appear to be coolant, as the coolant line coming from the top of the radiator around the front of the engine is cold also....
THis happens after the engine has only been running for say.. 1 minute on idle... is this normal?
