Just wondering if it's worth me heating up my copper cylinder head washers to Anneal them or is this an extinct practice?
-
Heat up until black, then dump in cold water-easy, I have a home made copper head gasket.

I'm sure I've read on here before these washers are not actually cooper but are copper plated steel?

At £3.47 each I expect them to be Copper right through!
Mine are not even remotely magnetic - so definetely not steel plated - they are Copper - the staining on mine is Alluminium due to Galvanic corrosion effects from the cylinder head & nuts.
Alluminium & Iron sit above Copper in the periodic tabe so that fits with my theory unless someone can come up with another explaination.

My original 400 ones were definitely copper plated steel, but I've replace them with solid copper ones so maybe someone has done the same in the past with yours Ted

Did you check if they were magnetic?

Mine were copper plated steel as well.

Cleary some are made from Copper plated steel then - would that be original fitting or an aftermarket fake item fited by PO's.
I have ordered 2 from DS as my two nuts down the plug holes had thin steel washers fitted - I hope the DS ones are Copper!

Original fitting Ted. We have had engines in for work that have never been apart before where some have just the copper ones fitted and others have the copper/ steel type fitted.

Ted, don't forget the two washers under the pillar nuts are dowty type.

I haven't slipped the head into place yet but thanks for the reminder - I bought the DS dowty ones in the end - tbh I've not worked out where the pillar nuts go yet - I'm thinking it will be obvious when the head is on.
Did you just grease the headgasket can't find the post that discussed this a few months back?
My head is a over the place today so I'm not fitting the head today - I get days when I'm not in the right frame of mind today is one of them so it's just reading up & viewing videos today.

I know exactly what you mean Ted, if you're not in the right frame of mind theres just no point. I've been there, tomorrows another day.

Nice to know I'm not alone with that mindset - I blame my age I'm 73 - fully retired so optimistically still plenty of sand left in my hour glass of life.

There my be plenty of sand but everyday the hole in the glass gets a little larger and the sand runs a little quicker. ;)

At my age, I forget to turn the hourglass over all the time.
