I went to the dealer today to clear this whole issue of valve adjustment. The Mivec engine has VVT or variable valve timing system in it. I like and hate VVT's cause if your motor starts making noise its one of a few things. The VVT valve isn't working right, the chain became stretched or the tensioner for the chain isn't working properly anymore. We replaced hundreds of these parts on Mazda CX-7 engines all the time years ago.
So asking the service advisor at my local Mitsubishi dealer, (3 miles from my house) said that the info in the maintenance guide says that applies to older engines. And since I drive 1000 miles a week and its hot in florida most the time I might consider getting my cvt fluid serviced at 60,000 miles instead of the recommended 120,000 miles. Which costs 160.00.
