changing frost plug in zs1115 engine

Changing frost plugs in changfa   ZS1115 head
The Zs 1115 has 3 frost plugs in the head two outside crank case and
1 inside

You have to remove the valve cover to find the third one, if this one pops water will enter the crankcase

This plug is a 31/32 which is not available in the US so we will use 1 inch .
But it has to be modified  to fit into the hole .  The new frost plug looks like this

If you just pound the new one in it will look like this

But if you take a file and remove the skirt down to about 1/8 of an inch or less

Then pound it in the hole

Then take your file and level up the plug and with the head as the rocker arm partly cover the plug
