JFP is too modest to say so but you are unlikely to ever read a Post about the M96 than from anyone more qualified than him.
BTW see Post 6 above. You still haven't asked for a referral to a competent M96 mechanic in Vegas , so I give up - horse to water......
There are good M96 mechanics who need our business and support. Why use a general mechanic(& he may be brilliant) on an engine as peculiar as the M96 and expect a good result?
