Re: Do your Oil a Favour

Hello Dave,
Details please of how you secured the zinc, what shape they were and where you placed them.
The book 'Rust & Rot' marked interesting reading and shows the efficacy of using zinc.

Re: Do your Oil a Favour

It all started when I was given an RN saloon which had stood outside for 50 years, the bonnet and it's stay were a pile of rust on the cylinder head in which lay the Rist horn. The cylinder head core plugs had rusted away together with their seating so I tapped the holes out 3/8" BSP and fitted 3/8" BSP hexagon headed plugs which were drilled and tapped 5/16" BSF blind holes into which was screwed the 1/2" dia zinc anodes about 1/2" long but not long enough to bottom. Also 1/2" dia zinc bars drilled 5/16" slid over the water outlet connection stud, again length to suit so it doesn't prevent the outlet connection from seating. I keep looking at the blocks to see where I can fit anodes.
This was done about 4 years ago and a recent inspection shows no rust where the anodes are fitted, not like your Ruby engine Geoff.
