On my 3GM I cleaned this out 3 years ago. There wasn't a lot of muck even although it hadn't been done, AFAIK, since fitting the engine in 96. At the time, I wondered if the scratches left on the surface prising the muck off might form a key which would promote future growth of carbon. Well, I took it off last week and it was virtually blocked solid. So much so that it had to be chucked ..
Anybody else seen that happen .. ?
the engine wasn't particularly smokey beforehand although the reason for doing the elbow was that it started to belch blue smoke & unburnt oil at high revs.
Marine Power at Bursledon offer a much cheaper alternative elbow to the Yanmar part. A few years ago, I used to get all the routine stuff, filters etc, from a USA cpy which also ran the yanmar help website and you paid in $ what would cost same number of £ but then Yanmar restricted their sales territory and the US cpy couldn't supply to anyone not in USA. This peeved me but I see that Marine Power now host the website and it has grown into a very useful site
