Submersed Engine Damage

[not sharp]

Well. when we have a boat sink we leave the engine under water until we are ready to begin repair immediately. not great foe steel, but does not both the other alloys as much.

yes, that keeps (most) O2 away -- some O2 is dissolved in the water, but the worst thing is wet iron that is exposed to air

and salt...

When I read their description, I hear them saying "we normally wholesale cars and parts to reputable retail dealers but none of them will touch this hunk of crap with a ten foot pole, so we are listing it here for you suckers on Ebay"

I've duck hunted coastal marsh for years. You can literally see your equipment rust before your eyes. There won't be one part on that engine that is worth more than scrap value.

Good point. But:

"reputable retail dealers... like that guy they mention who was in prison?

On the car dealer scale, that guy may still rank right up in the top tier, despite incarceration!

I didn't see that part. What a crack up. I started reading the description, but after a while all I was getting was "blah blah blah...."

[randywebb]

It is a crack up -- stay tuned - we'll see more for 2 reasons:
1. 911 prices increasing
2. more cars from Katrina to come

I live on the East Coast of Florida and am always fighting the efects of the salt air. All the magnesium and aluminum left unattended, gets a white scale that looks like coral. This is just from salty, humid air, let alone being submerged in brakish water.
If you want to sink huge dollars into a complete re-build, I would stay away.

[randywebb]

That is Mg-oxide you are looking at or Al-oxide. It is the equivalent of rust for those metals.

The solution to the problem is simple -- use stainless, or even better, use Titanium and Gold.

[I said simple; didn't say cheap.]

Aluminum is a silvery white metal. The surface of aluminum metal is covered with a thin layer of oxide that helps protect the metal from attack by air. So, normally, aluminum metal does not react with air. If the oxide layer is damaged, the aluminium metal is exposed to attack, even by water.

So the aluminum oxide you see on the metal is protecting the surface from damage from the air and water. My bet would be to worry less about the caustic effects of the salt and more about the nobility of the aluminum. You see unpainted aluminum boats left in saltwater for extended periods of time frequently. But the one thing you will find on them is zinc. All over the place. Aluminum is not a very noble metal so it will be affected by electrolysis as represented by the "coral" and pockmarked look of the metal.

Those stray electrical currents were probably all over the flood zone. It would be interesting to get a look at it. I would bet the crank, rods etc might be OK. Hard to tell...

We are a Pa dealer who has specialized in 911's for many years. Previously we only sold our salvage Porsches only to other dealers such as SPS in California and Kempton Brother before he was arrested.

What kind of idiot puts things like the above in their Ebay auction? This ranks up there with the idiot selling the MM 3.6 "conversion" in the NE part of the country. Maybe they are brothers!?
