Core/freeze plug size

PDB · Postby **PDB** » Thu Feb 12, 2015 10:04 am

Had a google but no luck and don't want to take the manifold off to measure it.

Anyone know what size the core/freeze plug is above the starter motor please.

Mines just started to weap

The EPC shows the small size is 35mm (5 in the block) and the 1 bigger sized plug is 40mm.
So on the exhaust side there's a 40mm plug beside cyl 3 and a 35mm plug by cyl 4.

Thanks, it's the 40mm one that's gone.

Tiny hole at the end of the blade, makes me wish I had replaced them all when I had the engine out and in bits

The OEM ones are steel? I thought I saw pics of freeze plugs that looked like brass. Aftermarket maybe?

I think most are zinc plated. My engine sat for 15 years before I got hold of it hence the poor condition of the plugs.

Even the timing belt tensioner was seized solid, all the grease had gone where is had sat for so long.

Most engines won't be like this.
