Ahhhh, plat iridium which brand?
Bosch Platinum iridium.
I would like to stress its NOT the issue of the spark plug, it was LIKELY the temp rating.
The bosch plat plugs were literally too hot for my use case =D

No picture when overhaul being carried out?
Nah, as i mentioned, changed the WHOLE engine top!
Valve seats can be repaired, but not cost effective, and longevity not guaranteed,
so went ahead to change the whole block.

Just stick to your budget, monitor your oil and change your oil when is due.
Agree. There no such thing as TOO GOOD of an engine oil for any engine. Depends on use case.
