Just wondering what year that VW started using hardened valve seats on standard T1 engines.
Any ideas?

Cheers

The steel valves wouldn't last very long pounding into aluminium heads would they?
You took the words right out of my mouth hehehehe
I read it on FACEBOOK so it must be true

I'm confused. How come when we talk about unleaded fuels, we talk about harden valves seats coming in around '69-'70, and that you can only run unleaded without additives, in engines with hardened valve seats.

Anyone care to enlighten?

I think it might be a myth?? The seats were always hard steel. Valve seat recession is something that happens on cast iron head engines. VW heads might drop seats now and then but that probably isn't related to unleaded fuel. Plus how many VW's would actually have their original valve seats from pre-69 anyway. There is a mob in the UK that sells "unleaded" conversion heads which I think is rubbish.

Some of the Leaded additives for unleaded fuel are good for the valve guides which can wear heavier with unleaded but seats are ok.

I think your thinking of Holdens n Fords any motor with an alloy head has hardened seats.
