(To the tune of The Beverly Hillbillies)
Come listen to my story
'bout a man named Joe.
A poor country boy,
couldn't make his Mazda go.
And then one day he way tearing down a block,
slipped off of the bench and it landed on his ****.
(Berries, that is. Meat & two veg.)
Getting ready to take this engine block to the machinist, and an idea occurred to me.
On the 1.6 and (allegedly) early 1.8 blocks, there's a convenient threaded port on the hot side of the block back near the bellhousing where oil is taken to supply the turbo. The later cases obviously don't have this hole, as they were never used in a factory turbo application:
Now the question is, would it be practical to add this hole to a later block?
When I originally thought of this, I didn't have an engine block right in front of me, so I figured maybe there was an oil galley running right behind that position just waiting to be tapped into. Now that I've looked closely at the back of the case, I'm thinking this may not be so. If my assumptions are correct (judging by the location of plugs and lumps) this is basically what Superman would see if he looked at the back of the case with his X-ray vision:
Looks like in order to reach oil, you'd need to drill roughly 5 inches into the case. I'm not sure I'd trust a machine shop to make this cut, given that if they go slightly off-axis, the case is pretty much junk.
I was really hoping to avoid having to run a hose all the way around from the pressure sensor port. That rubs me wrong in much the same way as the stock Greddy drain configuration...
