WITW - Mark's poorly Dolphin

[MikkiJayne]

Having made a shopping list and ordered a bunch of parts, I wanted a better look at the broken engine to see if it is saveable, should a head turn up in the future. Also, we wanted to see if the cam chain tensioners were still good, as I know the ones on the replacement engine are not.

Bank 2 tensioner removed - this crud in the oilway is what destroys the filter gauze which then kills the tensioner. I've never seen this much before though. I think this is gunge from the mayonnaise detergent effect cleaning everything out



Amazingly the gauze has survived!



Alas the bank 1 gauze and consequently tensioner has not survived. No idea why its always bank 1 that goes first.



The start pin still locks, but the non-return valve doesn't close fully so this will make a very brief rattle on startup, but not frightening clatter that the start pin causes.



The creamy slime drips out of every oil way



Well, you can tell which cylinder was ingesting water Its spotless!



The head has been cleaned too



The cylinder wall is perfect though - I feared the water may have washed any lubrication off the bore and caused it to be scored by the rings but it has survived, meaning the engine is definitely saveable in the future



A slight stain on the cylinder wall from where the water has been dripping in, but there's no damage to the surface. Its just discolouration.

I started stripping the engine to clean it up. I want to get as much of the emulsion out as possible before storing it so it doesn't end up separating and leaving the engine full of moisture.



Not too bad under the valley cover



The oil retention valves are pretty nasty though. I don't want to retain any of this!



The upper sump is pretty dirty too - all the usual carbon deposits have been loosened up



Very clean in the block though - all the carbon deposits have been washed off in to the sump. Just lots of the emulsion hanging about.





Cleaned with carb cleaner. Once I've got as much slime out as I can I will spray the inside with oil to keep it clean until I find a head for it.



I tipped the engine on its side with the remaining head down, with the cams removed, so the gunge can drip out under gravity overnight.
