Just finished a service on my 1700 t2 and I found some red stuff in the oil. What is it ? Is it bad ?
that's what i was thinking hence my hard or soft question - could be cork or gasket - feel the oil is it smooth? any swarf in there?
That's the motorcycle equivalent of Blue Hermatite, otherwise known as bodger's seal. I'd guess your sump plate was sealed up using plenty too much then the excess wiped off the outside.
It's completely unsuitable silicon sealant that the engine builder used to join the case halves. If there isn't some blocking an oilway somewhere and waiting to deposit it's doom on your summer holiday I'll eat my hat.
how long's it been since you dropped the oil last? as zed says it could be inside somewhere which isn't good but you may be lucky.
Fill it up with cheap oil run it until hot and drop it all out again. Inspect oil and continue doing this until no more comes out.
Indeed but use fresh oil for the 1st one. That sh1t breaks down into tiny pieces and clogs up in all kinds of places, ask any Honda owner.
Maybe the gauze filter did it's job. Hope so. It's one of the reasons silicon is totally unsuitable. The other is that the case halves are joined together dry before boring for the bearings. Silicon doesn't squish out enough on reassembly potentially leaving the shells ever so slightly loose in the case, though as we can see it does squish out quite a bit leaving the worms of destruction floating around your engine. Sorry to be blunt, but if you had to rebuild it, better now than after it's let go of a big end and scrapped the crank.
yeah, don"t "hold anyone's hand" now zed !you could have at least done the "ive got good news and I got......"
Sorry I've thought harder and yes the crud would get caught inside the filter and settle on the plate.
