Re: Dirty/brown/orange colour cooling water

The smokemeter used for checking diesel exhaust emissions would appear to be an entirely different machine as used by heating engineers and as such you could well have a problem here methinks. However should you be able to obtain a diesel smokemeter there could exist an opportunity for your Chief to...

Re: Dirty/brown/orange colour cooling water

Yes, I have sniffed header tanks before, it's certainly not a weekly or even monthly happening but provided the smokemeter is calibrated correctly and it's not a Mickey Mouse one ( looking on the net I see loads of them out there ) you should be able to detect any HC's present in the coolant system....

Re: Dirty/brown/orange colour cooling water

Ref. your remark concerning combustion products if you have access to a decent 4 or 5 gas analyzer machine another quick easy check is to ensure it's set to the HC mode and waft the sensor across the top of the header tank with the cap off having just run it up for a while and it will "sniff&qu...

Re: Dirty/brown/orange colour cooling water

In what year would these engines be and what do you mean by " full overhaul " carried out?
Piston/ liners/ bottom end/ crank grind / heads / new oil pump etc?
Interesting one.

Re: Dirty/brown/orange colour cooling water

Might be an idea to test the stats. too. We got a machine like a giant kettle, round holes in the top plate for the stat. to sit in, large electric element in the water container side of things to provide the heat and a built in temperature gauge to indicate water temps. Turn the stat. over, read th...

Re: Dirty/brown/orange colour cooling water

Pump up the coolant system at varying temps and see if there is a psi drop.
And run it with the psi gauge attached

Re: Engine cannot start

What like opening isolater shut off valves maybe? I always reckoned that air was good for supporting aircraft etc but never did fit in very well with fuel systems. Bit like being offered water really when out on the ale. My take on that stuff is it's best used for supporting fishes and the like. Can...

Re: Engine cannot start

I well remember from school days concerning the Dutch boy who saved his town by plugging the leaking dam with his finger but I suppose its to much to ask if that was how the journal oil hole was plugged in this case

Re: Engine cannot start

I well remember marvelling in awe when this happened way way back . Thinking about it now, if the bottom end was let go on the crank how was the OP kept up? Must have made up an expanding mandrel type device for the oilhole to prevent it pumping against no resistance and endangering the mains/ bigen...

Re: Engine cannot start

Could be the Doxford one that came back to uk from the other side of the world way way back .
Crosshead, piston and liner removed to get her home.
They boasted about it for years I well remember.

Re: Engine cannot start

Revolver, Beware, I fear we must excercise caution here, this could well be a rebadged round and rounder/ hair drier Ge2500 series type jobby whereby it wouldn't have conrods or Pistons fitted. Could be a setup mind. Worst things happen at sea as we all well know. You know, grind off the rivets/ bol...
