Been running the 2876 In line 6 @700 Hp for the past 5 years from 480 to 880 hrs and zilch issues , yup zilch . Fresh MAN spec oil and filters...
There was a batch of faulty Bosch injectors around that time . A certain number hosed fuel [ stuck open ] and pistons melted with catastrophic...
Perhaps it’s mitigation against another class action or other lawsuit . They lost (eventually) first time round . So by saying remove and test...
Fit manual pull levers and be done relying on electronics in hard to reach areas in a salty environment.
Looks like a water injection elbow . Show a pic of the part in situ ?
Take a look @ Apreamare
A shorter stoked engine will like to rev more than a longer stroke one as well . It’s to do with mean piston speeds ,they are lower in a shorter...
He won’t have EGT or load gauges. Guess only water jacket temps and oil temps . If theses are high ish it may mean the coolers are ready for a...
It’s underpowered imho . Aged engines need a little nursing and care . I have only one 1/2 ( 2003 ) 13 L straight 6 ....2876 .700 Hp .In the...
Agree . 4/6 K hrs is about 10 years + normal leisure boating ....arguably near 20 years for some .So a big rebuild if they were in a boat wouldn’t...
So let’s eliminate “ open E valve / bad timing “ as wear means they actually prematurely close as the gap widens .Power is lost as the gas mix is...
Right / Ok gotcha . Sorry I,am ( and suspect mist on here ) unfamiliar with the MTU service schedule.......thought the heads come off in routine...
MAN s exhaust valve lash is 0.6 mm , the inlet is 0.5 . They tend to wear open ie get bigger hence the tapperty sound . The exhaust clearance is...
“ closing errors “ I mean gas is prematurely escaping because the E valves are not tight enough closed within tolerable timing . How ever now you...
How ever on reflection 304 heads in 3 yrs it’s unlikely to be a valve timing error so many times . Generators running UNDER loaded most likely ....
If it’s just the seat only and not the valve itself then I suggest the valve clearance of the exhaust valve is too close , ie not a wide enough...
Same here I run my MANs as far as I can up to temp + pressures at the dock in the winter regularly.Just to spread the oil , prevent gaskets...
Heats up things expand and the water leak self seals .......for now . sounds like water = intercoolers are timed out service parts . Worth...
Sounds like a relay somewhere in the circuit is stuck .Might supposedly momentarily energise when turn on to test everything like the klaxon ,...
Additionally not mentioned is the ECU history . Need to know if anyone has messed around with the engine (s) ECU,s ? Sometimes with upgrades or...
