Default Nanni Diesel Engine Problems

In your market it could well be worth your while to take a course in diesel
engine repair. It's not rocket science. Even I can do it.

Probably hard to find for a boat but some people have big truck diesels
bored in place. Otherwise the engine removal is a given cost either way.
I see you have cost issues that maybe we don't have. Around here swapping
the parts to a long block would be cheaper than buying a complete, ready
to install engine. Some machine shops will bore with the crank and the
other 3 pistons still in. Boring is done from the top.

I am not sure of the terms, but the mechanic said that his labour to
pull the engine out of the boat and then to strip the engine of all
parts to just the block, in order to send it away and be bored out, is
expensive enough. Then, add the cost of someone upsizing the piston
etc, as well as rebuilding the damage to the valve cylinder and then
inserting a new seat. For eample, because everybody here is a
specialist nowadays, the fuel injector will cost $110.00 per injector,
to rebuild.

He said before he gave me a quote to do this repair, he wanted to see
what a new engine would cost, complete with all marinised parts,
including gearbox etc, and then just the Kubota engine cost. which we
could marinise with the existing parts from my engine. This way I can
choose which option is price effective, while carrying the least amount
of risk from existing ware and tear. He is certain that the cost of
subcontracting the specialised repairs of various critical parts and
adding his labour for striping and rebuilding the engine and putting it
back on the boat, will be very close to a new engine. My friend who is
a qualified mechanic along with his brother, another mechanic, spent
over $4,500 here to repair his volvo engine, and he did most of the
labour. As soon as I have these prices and the options I will post it
on the net if you are interested.

I know very little about engines and repairing them, but the longer I
own a boat the faster I am learning. If I said tractor, any mechanic
would not dare to say anything that started with one thousand, but tell
them boat and they tell you not to get your hopes up for anything less
than ten thousand. There's a great way to make money........JUST ADD
WATER ! It makes every grow ten time bigger, including your bills.

In the US a short block means without head(s). And neither includes
anything other than the basic engine. We would call an engine with
and accessories a complete engine, not a short or long block. At your
a long block should be satisfactory, your accessories should be ok. I
am a
bit surprised that a single bore, replacement piston, and a valve seat
replacement will cost close to the price os a diesel long block but then
not where you are either. Is he pricing just a single bore? Or a
and replacing all the cylinders? Some people don't like doing a single
but frankly I don't think it is a problem to punch just one out 1 size

Just found out today that the bore was scored and could not be
adequately rubbed back and because the block does not have a wet
sleeve, that the engine is pretty much useless. The cost to re bore
piston and rebuild the head would probably cost more than a new
The mechanic is getting quotes for me now on both a long and short
block, depending on whether we use some of the old parts like turbo,
etc from the current engine. He also said that because the engine is
pretty new that there would be no market for the engine to be sold to
re conditioner of engines as there would be little demand for such an
engine for quite some time. The head around the valve seat was chewed
little, but even if it can be repaired, (and the mechanic is not sure
it can be) it seems that the cost of checking out the other valves,
injectors, the bore and so on would almost warrant a new engine. I
you are wrong about Nanni, or their Australian distributors, because I
have the most expensive row boat in Australia at the moment. Thanks
your comments.
