on the front of the timing cover on a series 1 motor. there is a place there that is flat. and has a bolt hole there. it looks like it is there for some sort of fitting that australia didn't need. if i drill into it to put my oil dump there. am i going to find a water jacket?? does anyone know. i would be thinking no. but i have never had one of these motors apart so i don't know for sure.

yep its the mounting pad for the cam sensor, you can drop oil back in there, but theres not a heap of clearence behind it though.
depends on what sort of fitting you use

i had thought about a screw in fitting. then i thought of maybe using that bolt hole to my advantage. i might put another bolt hole in there bolt a flange to it. i don't know if one bolt hole would seal it enough..
thanks for your help on that doctor bob..
