That photo is a great illustration.
There was talk in the fall of alloy intake manifolds being produced.
I assume that this was one of the reasons for going that route?
Is there any more word on that project?
well the weather was good to day so jacked the car up and got the torch out carnt see any traces of coolant leak or stains from the inlet manifold area or block. theres no sign of any coolant stains anywhere its not even leaking now, so will have to investigate further. by the way my coolant is blue been in the car since i got it. i think my best chance is to get some coolant dye and a ultra voilet light .
