Water in cylinder....diagnosis after slow cranking

I'll have a look thankyou. Another question if I may ?! The vetus waterlock.... from the exhaust elbow the flexi pipe runs down to the vetus. The outlet side then rises up to the exit. Theoretically, if I undid the engine side of the vetus is should drain everything before it. And the vetus should not let water from the outlet back through it so I flood my boat out ? Only other way is to ratchet strap the boat down to the bank to try and lift exhaust outlet above the waterline before draining.
 
Still unsure of how to get on the flywheel bolt to tune the engine ? ?
Would I do any damage by cranking it over with starter now injectors out ?
Might chuck some diesel down the cylinders first ? I've drained all the exhaust anyway. Tied it down to bank and lifted exhaust outlet from water to double make sure I wouldn't be sinking anything today

Sorry….I meant balancer….not flywheel. Wrong end.

id make sure other cylinders are clear of water and flick it on the key with the Seacock shut….but then I’m an optimist?
 
Think I'm a bit snookered has to how I get onto anything. That end of the engine is busy and faces a bulk head / wall.

Anyways...I drained sea water system. Emptied cylinder. Wd40'd all cylinders, sucked them out. Poured diesel in all cylinders, pumped it out. Covered the engine in an old t-shirt, jumped the starter and got a face full of shit. Certainly blasts it out eh ? Tried this another 3 times and seems to turn over pretty well. Turned it all off and banged some more wd40 on for now. Boroscope of cylinders makes me a little nervous as is some corrosion. Certainly not enough to stop anything. But may be wise to gear up to sort I'm future.
 
Not greatest of shots of bores but...

I had a tractor and the engine was about 30 years old, basically there must have been an imperfection in the casting of the engine liner as rust had eaten through from behind the liner wall and a small hole had been created, so every time the piston went down it drew into the cylinder a small amount of water. Fortunately the engine had a liner and I was able to get a new liner fitted.
I wonder though, it was my practice to drain the water in November and refill it again in March. So over the years would I have been better off making sure that over the winter the engine has decent Antifreeze with the Inhibitors which stop engines rusting away internally.
 
I've no idea about the history of this engine but it doesn't strike me as being well maintained or marinised very well from the limited experience I have.
My latest issues all point to poor wet exhaust system. The lack of goose neck and correct type of anti siphon valve look to be causing a major issue of water backfilling from outside in rough weather. My guess is that when it's choppy the exhaust outlet rises above, then below the water line creating a pump effect. With the inadequate system inside the boat the waterlock is becoming overwhelmed. I went to the engine earlier to put it all back together. Only to find another cylinder full of water. The exhaust system has backed up again overnight after choppy conditions. Absolute nightmare. Bought a gooseneck to install now and ordered a proper anti siphon valve. I just hope all this water is not going to have left damage.
If it's knackered if I ever get it running again - It's engine out and a more modern one in I think.
 
So....got it all back together. Cranked it. And it fired ! Ran lumpy as I would expect but with some revs ran nicely after a min or so. Turned it all off again. Topped up the coolant in heat exchanger, turned the raw water inlet on....cranked it....and nothing. Turns over nicely which it didn't do before. But nadda.
I've tried a few times now after bleeding the fuel lines again and again. Just doesn't seem to want to fire back up ?!
Oil isn't looking as black as it once was. Its sort of dark grey now. Which again I would expect after the trauma of water anywhere in system. Obviously needs servicing now but that wouldn't stop it starting?
I'm ready to set fire to it !

Any ideas you lovely people ?

Cheers
 
Save the cigars .
Fingers crossed !
Interested to hear if it fires up and runs eventually tomorrow?
Let’s hope it was a overfill of the exhaust separator.
Good luck .
 
Going to get all new fuel and oil filters now. Flush everything and give it some love before I start it again. Think oil is contaminated with diesel and wd40 more than anything at the mo. Ran it for a good 20 mins with no apparent issues. So fingers crossed.
