4G6-MIVEC and 6G7/6B3-MIVEC

My Maintenance Manual for my '07 Outlander (which is Mitsu's maintenance service manual for every model they sell) talks about "adjusting intake and exhaust valve clearance for 4G6-MIVEC and 6G7/6B3-MIVEC engines only.
 
This is something that needs to be done every 15,000 - 30,000 miles at least.
 
My question is:  does the '07 Outie have one of these engine types? I know it's a MIVEC engine, but is it one of these types?
 
Thanks for sheding some light on this! :)

I don't know about those adjustments but what I can tell you is that the New Outlander's engine is 6B31

Isn't that something the dealer can do?

and should do. Adjusting the valves is a very difficult opperation, one requiring lots of skill, patience, and knowledge of not just what you are doing, but why.
Mess them up, and at best your car will run really poorly, at worst, you'll ad that motor to file number 13.

Yeah...why go over every word in the manual and want to do every service yourself??  Imagine what else you could be doing..

Oh NO! I am not wanting to adjust valves myself. That is way beyond my skills, no doubt.   I am asking because I might wish to "by-pass" the 30,000 mile scheduled maintenance. Dude, at that point MItsu doesn't change crap in the car. They check a ton of crap, which frankly, I could as well, with a fair degree of certainty about the part's condition, but only change:   1. Oil 2. Air cleaner filter 3. spark plugs - which I am not sure if the Outlander comes standard equipped with platinum tipped plug (the 60,000 mile ones) or the stadard one (30,000 mile).   I am also curious to find out WHEN Mitsu says you should change:   1. ATF 2. Fuel filter   The Maintenance manual is silent on this too (again, Mitsu makes a good product, just bad in communicating to consumers).   Now, I definitely wnat to do the 60,000 maintenance.. tey actually change some stuff then!

here's a good idea...just take care of what needs to be taken care of when it needs to be taken care of......

the valve adjustment interval is 30,000 miles.

HOWEVER.. in reality (as told to me by a number of mitsubishi trainers), they're probably never gonna need it.

Interesting.   Well, I saw in the manual that the intake and exhaust valves need to be adjusted every 30k miles, but only on the 4G6-MIVEC and 6G7/6B3-MIVEC engines.   I only asked because I am trying to save some $$ and if I could skip the 30,000 mile maintenance (and do what needs to be done, check all the fluids myself), that would be good. I think locally, my 30,000 mile maintenance costs like $370, which is a lot for me.   Let me know if you guys know anything else about this issue or if it is nothing at all.   Thanks! Enjoy the weekend! :)

My dealer wants $450 for the 30,000 mile maint....
Now, since I do all my own Maint. for my cars, I will not have this done by my dealer unless the engine is running badly because of "out of spec" valve clearances....Unless you are an abusive driver, I can't see a reason for these valves to go so far out of spec. that you have to pay all that money for this adjustment procedure....however, changing the plugs may be a big hassle and I may have Vinnie down the street do that job...
 
One thing...by doing my own maint., I wonder how this affects the warranty?  It doesn't define this clearly in the booklet.

abusive driving will have no effect on valve guide/seat wear.
chaning the plugs doesnt need to be done until at least 60k.
you can do your maintenence anywhere as long as you keep reciepts... and accept the fact that if you do something wrong (like drop a bolt down the intake) mitsu is NOT going to pay for it.

I thought the days of valve adjustment were over. Don't most modern cars have hydraulic lifters that require no adjustment??

Yes, I would think that if the Outtie is running like a champ, it would be best to keep a mechanic from digging into the valve train and adjusting the exhaust valves...screwing with a smooth running engine is the fastest way to start a chain of problems...
I have a Subaru Forester with 104,000 miles  and it runs better now than when it was new...It never had the valve covers off.. ...If the Mitsu V6 is running poorly then and only then, will I  have the exhaust valves adjusted.

due to the complexity of the valvetrain, manually adjusted valves are used.  They make it lighter and much smaller.

many companies still use manually adjusted valvetrains, but as is the case with nearly all of them you will probably NEVER need to do anything with them.
