Interesting to see what you see when it is pulled down.
With those and more kms on the several TD5's I've seen and had, the hone marks have been clearly visible.
I wouldn't have thrown rings at any of them.
Sure sounds like dusting/contamination.
Unless it was real hot once upon a time, that's about all that will cause an issue like this on these.
All the best with it.
For what it is worth, I'd just check the oil pump bolt, confirm the head gasket/dowels are done and keep on going with the the 2nd hand donk. Kms difference is irrelevant.
Pull the ancillaries off for spares/sale and shove the old one in the shed if you really want to hang onto it
Are you talking about the black plastic thingy that is in the hose that comes from the top of the rocker cover, and is inserted into the intake between air filter and turbo?Quote:

Only grasping at straws, just wishful thinking on your behalf
The airbox design is terrible. The duckbill at the bottom of the airbox is a good idea in theory but when the rubber gets old and hard it simply becomes a hole to suck dust in. Granted it is on the right side of the filter but it is also directly above the front wheel along with the intake, where all the dust is. The oval tube from the guard in the engine bay to the airbox is made of a woven material and brakes down too. The air box lid doesn't seal well either. I've fitted a snorkel, sealed the duckbill, sealed the hole in the bottom of the airbox that is manufactured to be there, covered the oval tube with Sikaflex and also sealed the part where the snorkle connects through the guard with Sikaflex. I did this to be watertight too.Quote:
