That post was just too good to be 'somewhere' and all credit goes to the orginal poster on the lancer register.

Excellent, thanks guys.

it never ceases to amaze me the lengths some people will go to help others.

Nice one. the pics have some great text on the to show exactly what to do.

can we have these pics in the library as how to guide.

anyway rep points coming to both of you.

Thanks again
Dave

Do be carefull though that if the piston is anywhere near tdc you could force the valve into contact. Also when doing an exhaust valve make sure its opposite inlet is not compressed by the inlet cam (and vice versa) Valve clip is possible on the 6A13 dohc.

[Nick Mann]

Andy - what is the clearance? You only need to compress the spring by a mm or 2, nowhere near the amount that the cam moves it. I certainly don't remember any resistance other than the springs. The only major issue for me was finding the correct lever point on a couple of the end rockers.

[The Vee]

The clearance should be more than you need for this operation. All I'm saying is be carefull, as these engines are not failsafe and contact is possible.

well i have done a remove, check and replace.

i only did the front 3 cylinders.

i will do a proper write up with pictures when i get the chance. but for now this is what happened. just read this back and it sound quite perverse poke a niple. but i couldn't think of a bet description.

Remove
as described above in pictures, easy job. i took my time and only did one at a time.

Check
all adjusters were soild aprt from one.
3mm hole on niple, 1mm hole on side.
the niple on top could not be pushed down.
when you turn the nipple on top they were a bit stiff/grindy.
so rotated them untill all felt smooth.
push niple down and oils came out of 1mm hole on side.
after that niple was free to move up and down.
poked around in side lash adjuster from top through niple with 1mm thick rod.
went straight to bottom of adjuster and allowed more oil to come out.
this oil was very clean, and no bits/muck in there.
so did not put in diesel bath as described in manul.

one lash adjuster was not stiff to push niple down.
straight after removal it was soft.
kept track of which one this was.

Replace
as described in pictures, easy job.

i now know i should have put some oil back in the lash adjuster after i squeezed it all out.

put everything else back together.

start car, sound like a bag of nails (no oil in lash adjusters).
leave to idle for a few minutes still sounds like a bag of nails.
do the air bleed procedure, rev to 4k back off, rev to 4K back off, lots of times.
all goes quiet, then tipping comes back. but only from one area.
listen to egine with screw driver in lots of places and it seems that the tapping is coming from the area where the squidgy lash adjuster went back in.

could be one of 2 things,
that particular adjuster is knackered.
oil way to that particuar adjuster is blocked or part blocked stopping it filling with oil properly.

to diagnose which,
i could swap squidgy lash adjuster with another from one end of engine to the other to see if noise goes with it.
or clean oils way some how. not sure how.


what do you think?

[Nick Mann]

Sounds like a fair description and summary. I did the clean procedure on mine and whilst it made the car better, it never cured the problem. Only new ones did that! So my best guess is that you have a knackered lasher. The oil way being blocked should have been noted when you put the lasher back in - you should see the oil squirt out of the oil way when you push it home.

VR4 specific pics and write up would be good. The article is mine, but I didn't take any VR4 photos. If you could write a new one or add to mine, then that would be cool!

[Davezj]

just post thread about oil flow see pic.

looks like i will be buying a lash adjuster as i think there is someone on ebay doing them as an £20 each thing.

and yes all oil ways were clear when lash adjuster were push back in.

the up rated lash adjusters is it the hole on the side that has been opened up to 3mm or the one on the top. mine have 3mm on top and 1mm on side.

[Davezj]

just ordered one from mitsi £23.96 inc VAT.

for my chassis number they didn't like the MD377239 code quoted in thread below.
http://www.clubvr4.com/forum/showthread.php?t=29540

They said originally it was MD171130 code
but that was superceded by MD376687 code

so orded one of them, i will find out tomorrow if it is the right one when i go to pick it up. i am expecting to get 3mm oil hole. does this sound right.

[Davezj]

well i just got back from the mitsi dealer with a lash adjuster with part number MD376687 it look like the right part as i have just removed and cleaned 12 of them so whats with the MD377239 code list in the other thread. i will fitt it this weekend and see.

just out of interest do i need to clean it before i fit it, as the oil it is covered in looks like 3 in 1. i will probably just compress the adjuster to remove the oil from inside and give it wipe rather than filling it with diesel. what do you think. just shipping oil that need to be removed.

[orionn2o]

Did you just buy one lash adjuster for 23 quid??

[MarkSanne]

my box of uprated chocolates says MD-376687 as well

[Davezj]

Did you just buy one lash adjuster for 23 quid??

unfortuneately yes, a bit pricey but i think i only need one. i will phone them back tomorrow to see if i was supposed to get 4 for £23.

the bag does say 4 pices see below. 3mm oil way though.

21129
21130

[Nick Mann]

That is the price for one lasher from Mitsy. Not four! That's why people don't buy a full set from the robbing gits.

[orionn2o]

eek thats expensive!

[Davezj]

right,
i got the part and fitted it and it fits fine it is the right part number.

when i diagnosed the initial problem as to which lash adjuster was ticking, using the old screwdriver to the ear technique.

so it made a massive difference, the ticking from this lash adjuster stopped.

but this lead me to discover that i had more than one ticking lash adjuster. the other one i have found is in the back 3 cylinders so the diagnosise of this one is going to be very difficult due to the inlet manifold being in the way.
and of course when you remove it, you can't start the engine to listen to it, Catch 22.
so i have ordered a stethoscope to see if i an listen to it in a bit ore detail.
but lets face it if you are going to go to the extent of removing the inlet manifold you might as well replace all the lash adjusters, as you don't want to replace the one you think is faulty, only to find after you have put everything back together it is still ticking . and you have replaced the wrong one.
so i will have to save up!!!
