still going directly into my oil pan I can look down
thru the timing chain cover with the valve cover
gasket off and pour water in the radiator then I can
see the water trickling into the oil pan right up
under the timing  timing gear by the oil pump and
main seal does anyone have a clue what my
problem may be ?

A crack in the head possibly or maybe the head is warped.

It's a complete brand new cylinder head new gaskets water pump oil pump and timing kit the only thing I didn't replace was the timing cover it did have a small groove in it from where the plastic guide broke off I'm wondering if the is a hole someplace in the timing cover that could cause this but I see the water trickling in near the crank by the main seal and oil pump maybe it's running down from the water pump making it appear to be coming from the oil pump area im taking the front end back apart as we type lol thanks for your feedback and any others may also be helpful if you have any other ideas of if anyone else has run into this problem any and all feed back would be helpful to pinpoint this problem thanks again
