Thanks for all the help so far. Another question... The fan shroud bolt closest to the oil cooler broke off into the cam housing. While drilling it out I drilled all the way through the 6-mm bolt into a recess.
Any reason to be concerned about this or the metal shavings that could've fallen in? I can't think of a reason why this area would be exposed to oil or bearings but just wanted to ask?
Next question: my trusty bolt extractor snapped off while trying to extract. Best next step? Employ a titanium drill bit?
