hi tony
no not double washers the head had been board out to take 9 mm nozzles when they was in it was putting fuel out on top of the water, so i changed it i put adapter washers in to go from 9 mm back to my old 7 mm nozzles and it seems to have worked. no more fuel on the water all runs clear.

hi tony
problem solved now it was the injector nozzles i put adapter washers in and put back 7 mm nozzles, just smokes for 5 mins at start up now then all clear,and no rainbow on water at all,and just steam at load. so as you said it was most like were the problem was spot on so thanks for your input.

we use her for lots low power work it became fumy i do not know why there was blow by,breathing a lot even up dip stick tube all i know is when head was removed there was slack in the pistons was told this would cause lots of the problems. and boars had scoring on them all.
when i first bought as a 220 hp the engine we did 4000 hours,then after rebuild now told 260 hp ?. its done 12 hours is all.
the 9 mm im not sure on that myself i’m guided by the mechanic ??. i think there putting in more fuel as if you stand at back of boat the smoke stings your eyes and strong smell. not sure of the long term of the engine as just bought as a recon to replace a old ford that blew.
injectors they used Bosch 0433171358 set for 260 bar the original injectors was 0433171431 think they was also Bosch.
sorry did not follow up your post was to late as he already changed the injectors just been trying to sort it but no joy on that.

was going to replace engine but decided to have it rebuilt instead as we had lots back pressure big loss in power burning lot oil etc and had run her for good few years.
all parts genuine Cummins , engine board plus.5,pistons .5 mm oversize,new turbo,lube oil pump,fresh water pump,new injector nozzles as old ones found to be faulty mechanic board holes from 7 mm to 9 mm as new nozzles only came in 9 mm so i was told. P 7100 pump rebuilt as delivery valves was broken .(power now back after pump redone)CPL number for rebuild is 2956. serial i got from you as we had no number originally number for parts etc is 45806470. hours from rebuild is 12 hours only. to me after rebuild sounds louder on tick over, when under load is fine and have good power back soon as you give her full load we get grey smoke from exhaust not steam. only thing we now have is white smoke on start up but go after bit, fair bit of oil or fuel on water from our exhaust.

thanks Andy.

HI MATE
THANKS FOR ANSWERING ME.
1. have asked for this as it was not on front cover like most. still waiting.
2.been told wrong nozzle for the 260 BTA so bought new ones(correct nozzle numbers according to chap who built it for me) and they are 9 mm when my head holes are at 7 mm.
3.washers are all correct injectors seated right.
4.being told the timing is spot on but will press again to check it.
5.just bought as recon 6 BTA 210 hp from local but had trouble from day one.
6. because we had so much back pressure and oil leaks everywhere, even pushing up the dip stick around back of turbo and big loss of power, and bad smoke under load so decided to have it rebuilt. and its not done 2 hours even yet could it need to bed in ??. could this cause the problem at start up.
7. starts on flick of key don’t turn over just fires up,runs bit lumpy then clears can send short vid of that if helps.
Appreciate your feed back as your site and knowledge is very good.
cheers Andy.

hi mate. everything was rebuilt all coolers was checked etc and new rings pistons re-board as was some vertical scoring, new turbo total strip down and rebuilt, but used the old head that has got 7 mm holes. we did get injector nozzles replaced before the rebuild but after it had been done we found out that they are the wrong nozzles and are not available in 7 mm so the new ones recommended by Cummins are 9 mm the hole in our head is 7 mm and are being told that we need these new nozzles for the engine to run correct. cpl etc i have to get from who rebuilt it after weekend and get them to you. do you think wrong nozzles could also cause this problem many thanks Andy.

hi mate. that was just on start up ready to go out average temp at mo is around 40F. she was out for around 2 months fuel is all good checked it plus new filters etc. the vid dont do it justice as it is real bad and smells very fuel as well. what im being told is the injectors in her are wrong ones according to cummins the nozzles are wrong they are 7 mm ones now got be changed to 9 mm. single screw before we had rebuild never smoked like it at start up before, do you think could be wrong injectors ?? im in doubt. appreciate your advise and input. the film on top of water is that from cold as well you think. thanks lot Andy.

hi mate
done like you said we drained old coolant could only run her up on berth as weather pretty crap here right now,but took her up to 85 it then settled back down to 80 more coolant went in than before by 3 liters so was air lock. but heres the crunch thought i check thermostat someone had put it in the wrong way round so subject to a real sea trial i would say its all good now. i send few pics as well later but thanks for help mate.

[Andy king]

thanks very much mate we are going to drain off tomorrow and re do i send message let you how it go. cheers

[Andy king]

thanks for reply mate sounds like air to me then as i noted the coolant was put in quick no hoses was squeezed all the above was not done, so if i was to flush the engine and put coolant back correct this could sort it ??.
