Yea mite have some luck with the scope ,like the two that where bent where almost unnoticeable by looking at it we had to full it with water to see if they leeked , amazingly the pistons and bores where in perfect condition for the kms was rather surprised, have alook on ebay before you buy chain etc dude u can get full kits with gears, guides, chains etc for half the price ud pay here just watch the shiping prices lol. like i found a valve kit that includes head gasket rockers ect for 500 + 150 shipping . And chain kits ranging from 300 - 600 .

To check the timing marks in my opinion its definitely a motor out job. As u have to remove sump to even get the back plate off and doing that between the firewall and the gear box would be what nightmeres are made of . once engine out thou its pretty straight forward . only issue we had the the damper plate on the steering being in the way of the drivers side engine mount. Left loom one the engine and disconnected from ecm was alot easyer then trying to unclip the loom etc . Im probably guna be trying to source a new engine as for me its realy not worth getting new valves ,head work ect just working out if its even worth buying new engine or replacing car sadly

been a long afternoon. But have the results of my problem @Cammsport. Chucked up a couple of pictures , wouldnt realy know unless ur removed the head apart from two rockers being ever so slightly lower then the rest

@Cammsport Sorry its taken afew weeks dude had some serious issues with getting injectors out . Figured id fill you in on where im at currently , so seems the intake cam shaft at cyl 4 rear has movement tinyest movement , the chain timming marks are fine and doesnt appear to have bent any valves but will know more as i go . Not sure if that helps at all. But yea thats kinda where im at currently with the issue on mine. My point being rotate the engine and watch the cam as u turn it . As i recall u saying u had low compression in 1 or two cyl ,as you may have the same issue

@cammsport , dunno dude. Weather hasn't been the best here so far hopefully tomorrow is abit better to start the mission for me . Sounds weird that only one piston would have " soot buildup " if u ask me. My first thought with mine was that is had got a bad case of bore wash causing the same problem with the rings not completely sealing . But yeah i've been searching for a block or buying a wrecked 320,520,120 with the same block and swopping out , end up costing the same as just buying the block cheapest ive found was around the 3ish mark and that way u can sell parts to get cost back but depends on ur space i guess . Ive Turned to (gumtree and ebay now) alot better prices and better condition blocks , and chain replacement kits , huge difference in price ,just the shiping costest is the biggest issue ,as a backup ,if it turns out ive jumped teeth and bent a valve or 3

Damit, So they didnt think it has jumped a couple of teeth? Im about to pull my motor out this w.e and have a good look at the chain timming as i disconnected the downpipe off the turbo and when i turned it over, it sounded like the exhaust side valves are slightly out of time. But im grasping at straws till i see the timing, has me stumped currently. Il keep ya posted, fingers crossed

Hey dude. Did you happen to find out what the cause was? Mine desided to do some very similar, and im basically at rocker cover off and checking the chain and timing also, just intrested in what you found beacsue my sounds the exact same 😳 ran sweet, till it didnt sigh
