I have blown 2 Turbonetics turbo oil seals with the oil return to an AAM oil pan spacer. I'm plugging up the oil spacer return and drilling the upper oil pan as per the turbonetics instruction.
With the return going into the AAM spacer the oil returns to the pan below the oil level. This may have been a factor in the failure of the seal. I'm not taking any chances this time.

how about running the return to the oil filter area via that sandwhich? at least it's above the oil level....
i was actually gonna install an oil pan spacer, leave that alone, and use the oil filter sandwhich for the return.......curious as to what others have done besides tapping into block............inputs more then welcome

It's common turbo knowledge that the higher the tap, the better. For healthy flow it's better to have gravity working with you, rather than viscosity working against you.
Besides, you aren't tapping "the block". You're tapping the upper oil pan which should be cheaper to replace (or seal) than buying a new turbo.
When I end up building the motor, I plan on keeping my existing block and retaining the tapped upper pan. I'll only be using the spacer for the extra oil capacity.

An oil cooler sandwhich plate (I assume you mean purchasing an oil cooler sandwhich plate) won't work. You can't gravity feed into a sandwhich plate. The only real option here is to tap the upper oil pan. It doesn't sound like something you would want to do but it's really a non issue.
+1 what Taurran said. The upper oil pan is cast aluminum and is not part of the engine block.

ok, page 23 of 41 line 39 states(install manual) "Using a step drill or 1/8" drill bit, drill a pilot hole into the engine block...."
did tn mistake that as a block instead of the upper cast aluminum as you guys noted? either way, no biggie......if anything, the pic on page 41 shows clearly how the oil will free fall with gravity down into the oil pan vs flowing into the oil via oil pan spacer.........sounds confusing, hope im making sense here....

again, I don't know of anyone other than jetpilot who've done this. The oil doesn't come out of the turbo like you think it does. It exits as a foam essentially. If you make sure it's all downhill to the pan, you can use a spacer without a single issue as I have for 14k miles.
