The official FABO machinist/member collaboration, busted 340 thread
I agree with the OP's choice to bail. Similar to my GTS threads where I shared tech info and results. You get worn down by the keyboard commando's and withdraw. I see two main types of commando:
1) The novice enthusiast that is so excited about the hobby they chime in on threads in which they have ZERO direct experience. This tends to be a regurgitation of misinformation, old wives tales and other half baked theories that float around the internet. No individual has every answer but PLEASE don't give advice without direct experience. Your tenacity to participate and help others is appreciated. Don't let that good intention become misguided.
2) The seasoned know-it-all that refuses to acknowledge anyone else's experience or knowledge . This person typically insists on one extreme or another (i.e. only use the cheapest parts made, all else is a waste of money) and will randomly badger other posters for no reason other than self soothing to cope with their parochialism.
In closing, STFU and listen to the people that work in the trenches. If you have not built it, run it or fixed it there is no need to provide your 2c.
We all read the same internet. Offering up widely accepted theories as your own experience can be misleading and cause a trusting member to have major issues resulting in costly repairs.
I will continue to call out both #1 and #2. I'm not here to make friends or enemies. It's about the cars.
Lastly, to the owner of this 340 engine. Please don't forget about the guy that helped you fix your engine. I have helped many, many people and not received a thank you, random check in call or an update and that degrades one's good nature to help others. It's not anything that is owed or necessarily expected. It is a matter of being thoughtful and polite. All of us fixers out here on the front lines are also human. It gets old when your "friends" call you only when they have an issue or tech question.
