Changed the filter today I cut around screw opened the retainer put new filter in then retained it with a tie remove bolts for easy access but no need to remove while unit

I have removed those bolts still will not come off

I have the service manual and it removes the sump , I have the cover ready to remove but it seems to be stuck at lower right side won't budge Strange no one on the forum has done the chain cover removal . Remove of the sump is not that easy as the access distance to frame means I might have to have to lift engine to get clearance that's why I am asking before I do anything

Do you have to remove the oil sump to remove the timing chain cover on IS220d

Injection volume jumping at idle when warm engine shudders then cycles to normal back shudder every min

Going to try purge next

Tested wiring to 4th injector all ok I removed 4th injector and connected it outside engine to observe pulse and diesel spray looks ok when running ran car hot and forced regen which worked at hot smoke disappears but 4th injector still reads +5 mm3/st next day car back smoking at idle get white smoke then black with soot on ground

Any suggestion how to fix

Any suggestions

Yes i think i will get bubbles anyhow - so will check

Just replaced 5th Injector with a new one no change on smoke and cleaned EGR few times still smoke , still injector 4 at +5.0 mm3/st

Only 120K klm on engine

I will connect pipe and bottle of water to overflow , remove the rubber on the cap and see if i get any bubbles - should i let it warm up

OK did compression test through the glow plugs , Cylinder #1 320 psi , Cylinder #4 325 psi (suspect injector at 5.0 mm3/st) So what now
