MC Engine that lacks a Turbo Filter

["Douglas H. Quebbeman" <dougq@iglou.com>]

Help!

I thought I had an MC engine in my '86 5kcstq (the data tag in the
trunk says so!), but today, when beginning an oil change, I noticed
that it lacks a separate ilter for the turbocharger! Right about where
it would be, there is instead a large (19mm?) bolt head (maybe a
banjo bolt?).

Was this done during a part of this engine's production run? Or,
is this engine from some other model/year?

The car was built in March 1986, VIN is 44-G-11415. Is the code
on the engine visible without removing stuff?
