It's a drain.

Subject: <VV> Bellhousing ventilation
I am putting my transaxle assembly back on my Spyder engine and I noticed
there is a ¼ hole in bottom of bellhousing about ½ in from mating surface.
I figure this is supposed to be left clear for clutch ventilation. I cant
see in the manuals or Clarks catalogue where there is any plug for it.
Please confirm whether or not I need to put something in the hole.
Fortunately I noticed that the engine builder put washers behind the 4
bottom bellhousing-to-block bolts which I will remove before I attach the
The clearance between those 4 bolt heads to flywheel flange is about 6mm and
would not be sufficient if washers were left in there.
I intend to get the Clarks C4763 kit and use new pieces for all 9 bolts.
Ive already got a new clutch disc and pressure plate to go on bolted
flywheel and the assembly has been balanced.
Its great to have the Clarks catalogue and technical papers to steer us in
Perth, Western Australia
