159 2.4jtdm inlet manifold removal and cambelt change...
ok so I have a few queries in this thread...
I had a remap a few years ago, egr blanked (in the remap but not physically blocked) and dpf removed, and on its first mot afer the remap struggled to get through emissions.
Spoke to the remap company and was advised that the problem was probably that she was still sucking carbon and rubbish through, and that the inlet manifold was likely to be full of gunk. Removed the MAP sensor, gave it a quick clean in brake cleaner and passed MOT ok. Ultimately was advised that the inlet manifold needed off, cleaning, and fitting of egr blanking plates...but that to do that the high pressure pump and cambelt needed off too.
the time has come to attack these issues as she has done 70000 miles now, and that seems to be about the general agreed cambelt change.
before I open the tool box...as I have never done a cambelt on a modern diesel...am I right in thinking that the fuel pump isn't timed to the crank/cam like in the old days...and that its just like doing a petrol engine cambelt...additionally are there any special locking tools...or ways to improvise such to ensure timing remains correct? hence removing the fuel pump wont require timing...so I can get the inlet manifold off to strip it down and clean it.
Also I have been advised that the swirl flaps are best removed and blanked off...whats the opinions of the floor to that?
