I am replacing on my 89 350 TBI the intake manifold gaskets. One was seeping coolant.
The new set that I bought from Summit, a Mahle set, shows that the back / rear coolant ports are kind of blocked by a piece of white tin metal with a small hole in them. My existing leaky gasket are fully opened !?
As the motor as been replaced by the PO with a roller cam 350 , I am not too sure what is what !
Any help appreciated. Thanks in advance.
