#7 down compression ideas?
The #7 hole has a helicoil in it. A compression test showed it at 40% and the plug had a whitish brown color and looked burned up. After replacing the plug, the test now has it at 12% down.. Could the previous helicoil repair have damaged that hole? I was told the insert was allowing the plug to get hot. Or maybe it's not a helicoil but a cheapey repair type that uses a hotter plug? It was a auto lite that was pulled out.
Would a proper time / big Sert fix it? And what can I do to bring the compression back on it?
Thanks!

miko, First.. Welcome to the site and the V10 section. Now,asking the same basic question in 5 threads almost back to back in a very short period of time is just a little redundant. If someone has done this they'll answer you. Have you tried searching the entire site, towards the top of the page in the middle there is a search function. Through the years I recall guys repairing the blown plugs with time serts and such, as far as gaining compression back I don't know about that. Don't forget about google or another search engine.
