Injector removal 2.4 mk6 diesel

[amlav]

Had to change timing chain after it jumped about 4 teeth .Got the garage to do it ($2000Aus) but than got a call that valve(s) seems to be bent and they quoted me $4000Aus (about 2000 pounds) to remove head and recondition head .
I thought that was a bit expensive and had the van towed back home intending to do the job myself (except the head reconditioning).
Pulled the engine out and took the chain cover of and surprise ..surprise ...first of all chain markings where not lining up with sprockets markings .
Well ...I thought maybe they just replaced the chain without bothering about the chain marks but the alignment should be at least correct .
How wrong I was . Camshaft sprockets and injection pump lined up ok but crankshaft was out 3 teeth . Could not believe my eyes and checked it out a few times to make sure I'm not wrong and I was not .
Called garage and told them about the wrong timing chain alignment and got told that was impossible . After telling them that I'll show them the pictures I've got
told off politely . Anyway would not take any car to that shop anymore seeing the bad workmanship ...even if it would be free .

Realigned everything and now I would like to check the compression to see if there is any damage or not to any valves but have to remove injectors and not sure what tools and how to remove them without damaging or what is the simplest way to check compression without removing the head .

Turned the engine over a few times with the starter motor and it sounded ok but I want to make sure there is proper compression .

Could anybody give me some advise removing injectors tools, compression testing tools ?
Cheers,
Andrei

Compression test threw glow plugs on them

You'll find it carnt be done as the injectors are internal same as th mrk 7 just different set up

Thank's Karl ,
Removing the glow plugs to check the compression looks a simple idea . Did just that .After undoing the threaded section of glow plugs had to pull them out quite hard . All seemed to be a tight fit . Is this normal ??
Two of them where falling apart anyway (inside electrode just loose in the main glow plug body ) .
Next challenge is to measure the compression with something . Put my finger over the glow plug hole and turned crankshaft by hand and so far all cylinders seem to have compression but I would like to be able to see the psi of each cylinder .
So far could not find a tester that goes up to 500psi . Any Idea of other ways ??

Foot pump.gauge ?

i have on of these

to be honest AS well to get a good reading on a diesel you need engine at running temperature so i always gauge at around the 200 psi mark for none runners

125psi or above for petrol engines

[amlav]

I've managed roughly to check the compression by using the finger against the glow plug holes method with engine cranked by the starter motor .
All cylinders pressure seemed to be equal and that sort of reassured me that valves are more likely ok . Otherwise have to get a tester up to 500psi than have to get some sort of adaptor to be able to thread the tester in the glow plugs hole .
Not familiar with the one on ebay , does it have adaptor that would fit in the glow plugs thread ???
Thank's

yes

Remove the rocker cover and see if any of the bolts on the rocker shafts are loose and if they are remove the cam carrier to see if its cracked.It is highly unlikely the valves are damaged on a 2.4

[amlav]

Hi Bamby,
Hmmm ... Lucky you told me about the rockershaft bolts because actualy I've found about 3 of them with the thread hardly holding and was about to fix the thread on the carrier with helycoil .
All of the lose bolts where on the inlet rocker shaft holding bolts . I'll check out the cam carrier and I'll post my findings .
What would be the reason for the carrier to crack If you don't mind me asking ?

Thanks Karl for the compression tester info .

Cheers,
Andrei

Bit of a bad luck...
As Bamby advised removed the cam shaft on the inlet side and sure enough the carrier housing where the camshaft bolts are screwed in 3 of them are cracked .
Now.... A few more questions .
If I get a new one does the carrier has to be machined or would it be just a stright swap ??? .
Roughly how much am I looking at for a new one and where to get them ?

Cheers,
Andrei

New cyl head im afraid

[amlav]

I would like to thank Bambi and Karl for the spot on advises in fixing my mk6 .
Finished up buying a new head but did not change the lot but only the cam carrier . After installing the new cam carrier I've compared the friction on the camshafts with the old one by turning them by hand . It seemed to be the same friction/ tightness as with the old carrier and that was good enough for me .
So far engine is back in the van and the van back on the road for 4 days with no issues . Runs smooth .
Thank's again to everybody ...
Cheers,
Andrei
