i am having some trouble getting my tccd to run, head was hitting and then when i increased the gaskets a bit(too much?) at BDC when looking down into the intake port the holes thru the piston are juuuuuust visible now. i think that is a problem.
i checked against a running tccd and you could not ever see the piston ports, BUT his piston was an aftermarket one.
i am just not sure how they work or what they do, should they clear into the intake and have an extra fuel boost, or do they just play at some other point?
there are two matching trenches in the top of the cylinder so someone tell me what is going on here, is this a boost? how does it work? :)
