|Asking for help isn't what I had in mind (this refers to a post that was deleted at its author's request - though she could have done it herself, nag, nag). What I'm looking for is closing circles - you ask for help in fixing your rudder (or something else - the rudder is just an example), a group of people give suggestions, you use or don't use them as the case may be, then you let us know which suggestions worked for you and which didn't. At present, many of our question/answer threads lack that last step.
On the other hand, we have an excellent example of follow-up in the thread, Atomic 4 Operating Temp - "whippet" asks a question about his overheating A4; he gets half a dozen responses, some recounting what the poster did with his engine and what it achieved, others proposing alternatives, yet others amplifying or providing a different persepctive on a common theme. Then, "Cap'n Tom" comes in asking for a new level of detail, duly provided. Finally Capt'n Tom provides a detailed account of what he did (while the memory is fresh), what he found and what he achieved. Ultimately, what we have is a much more complete picture of how to address an overheating A4.
