Disclaimer: I don't know anything, especially about 3.0. I looked pretty hard at a 2.7 once and stayed at a holiday inn express recently, thats about it.

Is this large enough... or can you mod it to be large enough to fit:
- oil pressure sender for factory gauge
- oil temp sender for factory gauge
- oil sump drian plug (committed to the low lyfe, bad idea)
- oil tank drain plug?
- some other unused port with a plug in it right now? (also probably where the Bosch sensor would go...)
- some case bolt with not a lot of air flow over it cyl. 3 or 6?? ..
It'll probably leak like a sieve. Prefect, up-to-temp. oil leaking all over the sensor for accurate measurement!
Alternate option maybe the Bosch sensor can be adapted to be the oil tank drain plug, that'd be interesting.
OK I'm out/
