[urq] Solid lifter I5 turbo with knock sender?

> Take pictures!  I was about to write after reading through the archives 
that it sounded a little like the teutonic version of Johnny Cash's '49 - 
'73 Cadillac.

The worst thing about these inspections is the long drive home - two hours 
in this case.

The starter motor is missing.  So I took the opportunity of checking the 
flywheel pins.  The owner said I wouldn't be able to turn the engine 
manually - "the previous mechanic had to use a HUGE wrench".

Hmm.  Now I think I might know why.
