Hello all. I'm trying to decide what best to do with my TAMD22 engine
, 1300 hours or so of unspecified but mostly light use. Visually very clean and tidy.
issues: Instrument panel electrics are dodgy and alarms are either nonexistent or intermittent. I need to get this fixed sooner rather than later, but it's not affecting the engine
significantly at the moment. Once a probably flaky earth somewhere is fixed I'm guessing this will all start working perfectly again. I suspect that I could get more raw water
flow through the engine, and I suspect that I could get less white smoke in an ideal world. But nothing about it is really bad. It starts instantly and runs very smoothly.
I had a basic service
done by the local highly recommended "marine engine expert" (there are no actual Volvo Penta
agents within hours of here). He wasn't exactly forthcoming, but when I asked what he'd do if it were his engine he said "Nothing. It'll be fine for another dozen years and won't let you down". He showed me a slightly high crankcase pressure (you can feel it with the oil
filler open), and a tiny oil leak
through the turbo which was causing a slow loss of oil
through the pinhole at the bottom of the turbo casing. He didn't think it was worth the cost of overhauling / exchanging the turbo though.
I certainly intend to open up all the raw water
system and make sure that's clear of bits of old impeller, and probably replace or at least thoroughly inspect the exhaust elbow
to avoid future problems there.
I don't use the engine much at all, although around here it can be very useful to avoid weather
systems and in an ideal world I'd want to be able to rely on it for 24-48 hour runs. I have been able to so far and it's been absolutely fine.
What would you do in my situation? Is it worth pulling apart all the turbo/cooler elements and overhauling that over this winter? Or do I just leave it be as the engineer
suggested? Or something else? I would probably prefer to do most of the work
myself as although the diesel
engine is probably the area of the boat
I have the least experience with I should like to get to know it a bit better.
