Jester, I hope you don't mind me borrowing the picture but it is the best one that I've seen of this.

I've seen a couple of pics of turbo cars running small blocks with the Oil feed plumbed into that area. What is it, is it something that I've got to drill myself and how do you locate it?

 

All factory blocks should have that oil hole plugged with an 1/8" pipe plug. I believe that is comes off the passenger side lifter galley.

 

Just an oil galley plug above the timing cover.

 

really? OK, I'll have to go look. How much oil pressure are you getting from there? (I'm a bit worried that much of the time my oil pressure guage needle is all the way to the right and the turbos only need about 15-20psi)

 

Hum, funky.

I checked they L98 in my Formula and found the plug (behind a bunch of stuff, which is why I've never seen it), but that actually made me more curious, since usually I’m fairly **** retentive and notice everything, so I went to the 3 engines that I'm more familiar with (owned longer, worked on more), and the 305 in my ’83 TA, the 350 in my truck and neither LT1 that I’ve got sitting around have that plug. For that matter, the 305 and 350 _look_ like they have more space between the timing chain cover and the intake manifold surface (shouldn’t be but both of them look that way), and the LT1’s have almost no space there.

So I wonder what decides if that plug is there? Sure seems like the easiest place to pick up oil from…

 

My bad, I should of said every factory block that I have see had that plug.
