Oil filler tube

[Sandeep]

Question.

I have a 914 case with FAT 911 cooling on a 2.0 GA engine. I was replacing the oil temp sender with the VDO unit to match my oil temp gauge and this is what I saw.

There is a boss for an oil filler tube that is closed off (Cast Over). When I have the 'Taco Plate' removed, I could put my hand in the opening and feel behind this boss.

Does this mean that I can drill out this area and catch all of the filings without splitting the case ? I could then install the studs for the oil filler tube with integrated dipstick.

This oil filler tube would transfer over to my NOS T4 case when I get the 2270CC built.

If I can do this then filling the oil with the FAT 911 Cooling system could be done through this tube and another problem would be solved.

Thoughts ? Thanks for any input !
