I'm familiar with the style you are referring to, older Mercedes engines have something similar; I've installed shims in them. At least with those you could leave the cam installed with you depressed rocker arm and installed the shims. I would like to see one these torn apart to be certain they are hydraulic. It doesn't sound good to have a design like this, though. What is the longevity of an engine like this, and what is going to happen to the MPG when these wear?
So the dimensional difference is in the buckets? In my 73 Alfa, you pulled the cams after measuring and recording the gap, the replaced the shims which were between the head of the valve and the bucket. with the cam lobe working against the flat top of the bucket to open the valve.
Only difference with the Mirage is there is no shim. The difference is in the buckets themselves. You pull both cams to change the buckets which changes the valve lash.
They will probably wear like the Alfa probably .001 per 150k miles. As long as the range of lash is sufficient like the Sentra's .010 to .023, then you will never adjust the valves in 500k miles.

That's good to hear, I hope it turns out that way. The dealer in Vancouver has some information for me, I'll try to stop by and pick it up in the morning and will post here on what it says.Quote:

Is anyone getting this service performed? The manual can be confusing, this is the answer Mitsubishi gave me regarding my 2014 Mirage;
"
Thank you for emailing Mitsubishi Motors North America. The service to inspect and adjust intake and exhaust valve clearance is not a service required for your vehicle due to your engine size. Thank you again for your email and providing us the opportunity to assist you. Please see below our current offers that we have included for being a valued Mitsubishi customer.
I have been reading reviews of the Mirage that state that valve lash inspection/adjustment is required every 30,000 miles to the tune of $299.00 at the dealership.
Its not required. There is literally nothing to adjust.
Save the email. if something goes wrong show them the email. In that case it will be their fault for misleading youQuote:

"Buried deep within the maintenance schedule is an unfortunate reality that all three-cylinder car owners must endure: valve adjustments. In the Mirage's case, this procedure is recommended roughly every 30,000 miles. The owner’s manual asks you to listen for a ticking noise and adjust when needed, "if valve noise increases adjust valve clearance," which is legal shorthand for, "if you don't do it and it breaks, too bad." The cost of this service at the dealership is $299 which, over the course of seven visits, would come to well over $2,000. As a guy who deals with dealers every single day, I don't see any of them not recommending this service."
Then it is needed :)Quote:
