Asking the hive mind...
When should I expect the stock oil return line gasket/oring to volcano out of the block and dump all my oil onto the ground?
I had an '87 760T with which I got to enjoy this experience 10+ years ago. Engine/turbo was stock B230FT with a Garett t3. I had also implemented the glorious manual boost controller on this vehicle at a pressure rating I can't say for certain. All I know is it didn't detonate on me at the time The event occurred when I was going to pass a truck on the freeway, and when it kicked down a gear at WOT I saw a plume of white smoke billow behind me as all my oil flowed through the block and onto the asphalt/sprayed along the 3" exhaust.
I RTV'd the s#!t out of a new gasket on that 760 and it held up after that, but that car is long gone now.
Since then, I've recently acquired a decent stage 0 945, and cranked up the boost to 10ish psi (spikes to 11.5-12psi because of the shi#y nature of cheap MBC)
I am basically waiting for the same thing to happen again...
I know it is a known issue, so I'm curious about the details. Is this a "keep the PCV system clean and it's less of an issue" thing or is this a "I should expect this to fail when I push XXX manifold pressure" sort of thing?
Of course I can tap it and thread a barb fitting or AN fitting, but that's not a concern. I was hoping to educate myself and others on the nature of this problematic failure of stock assembly via this post.
Curious what others have to say. Cheers!
