Hi all ,
Bin working on my engine and discoverd i had a leaking valve , so a rebuild is eminent . But searching tru the forum and internet gave me different opinions if installing
hardened valve seats would be a plus or not .
The general opinion is that our engines have no trouble with the modern unleaded fuel ......after seeing my valves i'm not so sure.
In normal driving i always used an addetiff to guard the valves , and try to find the highest octane fuel avalable , as a sort of peace of mind ...but still .
My question is ; would installling hardened valve seats have any disadvantage at all ?
