Re: [doc] M18 plug in engine - what is hiding under it?

[Martin Gutkowski <martin@xxxxxxxxxxxxxx>]

That plug goes directly into the crank case. It's the hole used to find 
#1 TDC on the crank itself - then used to set the position of the timing 
plate to the notch on the pulley.

This plug is not under any pressure - it just gets oil thrown at it from 
beneath. It's the same part as the sump plug, if you want to buy a new one.
