ok here is what i found i did not reinstall everything but hoping what i found was the problem. on the quicktime blockplate they have 4 holes up top to go around the galley plugs well 3 the 4th hole does not go to anything , also the gallley plug right above the crank did not have a hole so between this and the rear cam plug was not fully seated on the left side it was holding the block plate away from the block, i drilled a hole for the bottom galley plug and seated the cam plug also the machinist installed silicone over the plug which made it worse, the plate no sits flush on its own. i hope this was it.
