Mystery hole ;)

V40T4R · Nov 25th, 2018, 11:21

Hi everyone,

Preparing everything for assembly after a valve job, I wonder what's connected to the hole under plastic timing belt cover?

Pics of your motor welcome!

Thanks.

Miguel

maybe in the factory they screw in a towing eye so the engine can be lifted?

I doubt it though as I wouldnt want to lift an engine by the head?

My guess; For testing oil pressure during development. Or it's a drilling, to make a channel deeper in the head, plugged afterwards.

Thanks Canis, it's strange because there is nothing pluged...

Made my mind... will make a thread on that hole (G3/8) and install a blind plug!

Most of the cars I have owned have had lifting eyes bolted to the exhaust or inlet manifold on the head. And some of those are ally heads.
