Disaster!!!- sequel

Thanks, but that's not my problem as the filter is so inaccessible, I can't get my chain wrench in a position to swing it even a fraction, nor actually my solid, expandable spring clamp either- the only way to get this filter off with all the engine gear in situ is to jam my hand into the cavity between the filter end and the sound proofing insulation and bit by bit move it until it can be spun off. A very painful operation for my arthritic hands!

I'm not going to be critical of the yard as I've come round to the conclusion that my addition of a considerable amount of top-up oil is likely to be the culprit; it is a little annoying however that the point at which this excess has syphoned out can't be identified.

This is a first from the manufacturers experience and I would like to give them feedback as they have been so helpful over the phone (as usual)

Thanks for that Cliff. I'll have a look next week when I'm down.
The DV23 is a very rare beast, /forums/images/graemlins/cool.gif being the dyslexic version of the DV24.
Pulling the flywheel should be fun! Do you have any idea how much that thing weighs? Let's hope it's the pressure sender if it's either.

There is an oil switch on the block just forward of the oil filter, but if that was leaking it would have showed up on test pretty quickly. But you are right, it is a potential source of leakage if overtightened and distorted.

Thanks to everyone who made an input and especially for any I've overlooked acknowledging before- I intend this to be my last entry as all possibilities have now been eliminated and only one conclusion can be reached- I've overfilled the engine in the topping up process but the mystery remains as to where it syphoned out.

Anyway, the yard ran the engine all Friday afternoon on the test bench outside. It all worked faultlessly and no loss of oil.

This cloud however does have a silver lining, for as you will know the engine is really inaccessible and by squinting down into the darkness, when in situ, on the petrol filter side of the rocker box, the exhaust elbow which was replaced in 2003, can be viewed, but not easily reached. As I am aware that this is a well known corrosion point I do check from time to time and since the boat wasn't used in 2004, and only modestly since, I haven't been surprised to see a nice shiny galvanised elbow looking back at me.

With the engine sitting in the sunshine I was shocked to see that where the elbow dips away from my line of sight there is a corrosion split about 4 inches long ending just above the corrugated flexible pipe leading to the exhaust water trap. It obviously hasn't let CO into the saloon yet as my alarm there hasn't gone off but by the look of it I reckon it was planning on catching me out anytime soon.
