Yeh that was my opinion as theres no way you can here if a valve is out when it has to be set in the order of 1/20 mm.

When i got the quote they never mentioned anything about the valve clearances however, speaking to them since then they have told me that the service would have been around $500 more with the valve clearances done which seems to be in line with what Ive heard from others getting the 60 00 service done at other dealerships under the same branding. As well as this looking at the hours of labour they charged me for they definitely have not done the valves.

What annoys me is that they wrote on the receipt that they checked and adjusted the valves even though they never removed the rocker cover.

Audible check :lol: :lol: :lol: heard that one here sooo many times and even ended up with me in a heated argument at the dealer I used to use :evil:

I suspect mitsubishi are sending these 'special dealers' specially mutated human ears that can detect a valve clearance out by 0.001mm and report back.

Some spy's got me this photo of them...

Look it is only a rumor OK! I just got this envelope under my door in the middle of the night and it contained the above photo and a sticky note that read... "Dont do the tappet adjustment unless you get confirmation from this little sucker"

Maybe I am making a bold assumption but now another envelope slipped under my door... seems they have tappet ear detector version 2.0 :shock:

//I suggest everyone call their dealer immediately :lol:

Lee-thal...how would i KNOW my dealer did the work? what nut or bolt or something gets damaged/bent/knurled or scratched during this legitimate clearance adjustment process. :?:

Snowman,

You can but you prob need to remove parts to see it ie tappet cover gasket and seals , its like anything, its all TRUST. If you dont trust your workshop, go somewhere else.

You can here the tappets if they are extremely loose and i mean 2mm gaps loose. Most of the time there only around .10mm out so you can't here that. So thats just a load of shit unfortunately.

How the hell did that little pink looken thing have anything to do with tappet adjustment?

This thread "could" have been a sticky but u lot are a crack up...

Have never tried to turn over a diesel crank by hand, are they difficult to turn from the pulley to set the valves?

I use a 19mm spanner on the exhaust cam pulley and my screw driver on the water pump pulley to turn the motor over....

Yeah fairly easy just remove the glow plugs to lose the compression and its as easy as a petrol engine.

Just to round off; any special tools needed to undo fuel connections to injectors or get to rocker adjustments?

Has anyone had opportunity to get a few pics of the engine with the rocker cover off?

this injector(4) makes it a PITA to remove the cover... :x

Note the bleed off line wraped around the back could be damaged when removing the cover so be careful.

BG is spot on with his discription of this procces and the only injection pipes that need to be touched are the
supply lines into the cover... 8-) The bleed off line doesn't need to be disturbed.... :oops:
As Chaser said replace the injector seals on the top of the cover when you do this job, we didn't do this last time and they leaked on us but all fixed now (if I had thought about it I would have got the part number.. :roll: )
The ext valves are a PITA due to the cooler not allowing accses for a ring spanner.
Hope this helps some and for the record only had to adjust 4 valves and all were on the tight side but f all adjustment was needed... :roll:

See the wiring harness holder on the lower part of the fire wall, i normally bend that up so its straight to aid getting the cover off.

4 valves hey did a mn few weeks back and they take 4x as long to do than ml and i didnt have to adjust any! :x

good to see someone having a go its not that hard. With the exhaust side just us a socket and extension to crack the nut then adjust and tighten the nut back up and check again. Can be a pain full process but its sometimes the only way to do it!

When I picked up my ML from it's 30k service after the tappets had been done, it was returned with a random 8mm bolt left in the engine bay, the rubber seal in the tapper cover around the injector completely out blowing oil every where and an oil leak from inlet pipework after manifold had been removed. Cost a fortune too. Lucky it's a company car. Heartland castle hill.

I just helped my mech Chaser but when it is out of warranty I will def do it my self (need the mech's stamp till then).
As for the 4 valves he reckon that they were that close that he probably wouldn't have touched them... ;) but he reckoned that he wasn't going through that head f*$k just to run a set of gauges through it and bolt it all up..... :lol:
