sludge traps

[JayDee24ca]

Good Day.
Inquiring minds want to know: Did Guzzi stop producing their cranks with the sludge trap at the same time they commenced installing an oil filter, or did they continue using the sludge trap for some time after that? If they continued using it, at which model or year did they actually  cease using the sludge trap?
Thanks!

The use of the sludge trap and plug continued well after the addition of the oil filter. Looks like up until the nuovo 8v engines.

Charlie is correct.

Charlie is correct.

So that is well into this century, correct? That being so, is it normal operating procedure then to clean out the trap on filter equipped models when taking on a bottom end overhaul, or is the filtration normally deemed to be sufficient that there is no buildup in the trap?
The reason for these questions is that I am trying to get a sense of whether I should be considering tearing down my 40K mile filter equipped SPII to address the sludge trap or if that is a result of senseless concern on my part.
My (non-filter) Eldorado has 59K miles on it, and the crank was cleaned out at about 30K miles. Both these bikes have been rigorously maintained.
Thanks!

If you already have the engine completely disassembled, then I would definitely take out the sludge trap plug just to make sure there's no deposit in there.

Tear it down to clean out the sludge trap? Uhhhhh, no.

Yeah Chuck, I guess that is why I asked about the advent of the filter; on the older bikes with no filter, I believe there were cases where the trap became plugged, which lead some owners to tear down their similarly ill-equipped bikes for the sole purpose of cleaning out the sludge trap. As you know, this was true for bikes other than Guzzi as well.  My question (now answered) was not whether I would tear in the SP just to clean the trap, but whether the trap should be cleaned if the engine were apart already. I just hadn't ever heard much about the sludge trap on any bikes other than the old non-filter bikes.
Thanks
