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...

Re: Engine cannot start

Just idly wondering on this one, could it possibly be a Sub. and it's rigged for silent running?
Could be a reason for not hearing anything perchance?

Re: Engine cannot start

As the the silence is deafening on this one until we hear that now it's been purged correctly of all air present and in on all six research does indeed indicate that the Trike from the sixties is not the same as the Trike main ingredient of the engine degreasant I use regularly today. I suppose in t...

Re: Engine cannot start

Off with the air cleaner, out with my pump up spraycan container, out with the Gallon can of Tetrachloroethylene ( also known as Perchloroethylene ) ( slang speaky "Trike" ) as I have known it to be since 1960 ) fill up the spray gun ( it's a very good engine degreaser for pin pointing oil...

Re: Captain Bennett awarded merchant navy medal

Blow merchant Skipper it's called over here J.K.
Personally I'm a stinkpot boy. ( power driven craft that is )
Further on the downside the blowmerchants only ever drank halves.
As you well know us engineers only ever drank pints.
Hope that was always the same over there?

Re: Oil pressure mitsubishi s6r

Seem to remember the oil pressure switch/sender unit is not screwed directly into an oilway in the side of the block but is sat on a bracket bolted onto the side of the engine fed by an armoured flexy hose which is screwed into an adaptor in the block oilway. Normally a three wirer connection so by ...

Re: Oil pressure mitsubishi s6r

Look up the necessary ohms meter readings for that exact sensor and measure it to see if it is within top/ bottom limits. You'll have to heave to if you are a one engine jobby though. Fluctuations sound like possibly the sender / sensor unit as I have always found a worn rear main normally controlli...

Re: Oil pressure mitsubishi s6r

Remove the oil pressure sensor, screw an adaptor fitting with a manual oilpressure gauge attached and read the exact oilpressure throught all load / temp./ rev ranges. In other words bypass sensor/sender/ loom and electronic display gauge. It's called going back in time to how oilpressure used to be...

Dangers of DPF ing

FCR the system, deleted all stored old codes and ran the plant up. On comes the MIL light again, FCR the system and only one code is now displayed...

Re: $30 million oops

Maybe the US navy did a survey and as not many folk logged the "China's cold " Syndrome they decided to do away with urinals as there were obviously not enough candidates to satisfy the criteria for this age old marine engineering saying? ( well, over there anyway ) . Or is this the start ...

Re: $30 million oops

Despite much research I am still struggling with the causes of this gear cutting manufacturers defect concerning thrust bearings? Being interested in this problem source my investigations are not revealing much at all, understandably perhaps as it's a "security " issue together with obviou...
