How to avoid corrosion on a Volvo D3 engine

[BartW]

last winter the long block from one engine has been replaced, under warranty, basically due to damage caused by replacing a badly corroded fuel injector.

Now a few moths later, the other engineblock is also going to be replaced,
also here the corrosion of the metal fuel injectors in the aluminium engine block is a major problem, so they will probably place new injectors.

Soon I will have 2 almost new engines

what does the forum think is a good way to avoid corrosion on these engines/injectors ?
I have to admid that salt water was sprayed on these engines on a few occasions.
would a coating with WD40 and regular rinsing with fresh water be an improvement ?
any other sugestions ?

WD40 isn't likely to last long. Try Quicksilver corrosion guard, it's what they use on outboards. My 18 month old tender engine looks like new.

"Boeshield T-9", it forms a waxy film, developed by Boeing and is used to protect aluimnium alloys from corrosion on aircraft.

DUCK OIL is very good.

I use either 'INOX' or a very liquified lanolin in an atomising spray bottle.

Not that keen on anything that leaves a sticky matt finish on the machinery.

As Paul said the WD40 will just evaporate away.

Sorry to hear about the other engine Bart, I guess the Adriatic cruise will be put on hold?

The plan is, and we still hope that we can drive to Croatia next weekend,
we have booked flight tickets for the kids, etc, etc..
Epirb is installed

Volvo is replacing the engine block "today" (parts got in yesterday)
hopefully early next week we can do some tests here on local water.
keep fingers crossed

thank you all for the practical and usefull advice

Good luck mate.

Cheaper on Amazon though: http://www.amazon.co.uk/Swarfega-SD...ef=sr_1_1?ie=UTF8&qid=1278711443&sr=8-1-spell

WD 40 will not prevent corrosion. It washes/evaporates off leaving a clean surface which rusts quickly. That is why it is banned on board (abandon ship!!) by many of the navies of the world.
If you want to prevent corrosion use Waxoil, or some of the products mentioned above, that will actually leave a protective coating on the surface of the metal.

Something else you may consider - do the injectors have copper washers? If so there may be galvanic action between the aluminium / copper / iron of the injector causing the corrosion. My chemistry is a bit hazy but I know copper, aluminium and iron are non too friendly together.
