i had the same problem with the mini hei. but i caught mine before i had problems. the problem is when there making them. there not making the shaft long enought !!! in mine i took the o-ring of and used a thin paper gasket and that seemed to take care of the problem.
when i reinstalled my mini hei i used a screw driver to trun the pump to aline with the shaft on the hei to get it to fall into place right. when the motor truns over the cam will pull the grear on the disturbter shaft down. when you restall the disturbter us a small pieace of clay on the bottom of the gear to make shure the gear is bottoming out in the oil pump.
one more area to look at is the oil pump ! was the oil pump installed right. was the oil pump locked in with bolt ?
