Replaced Voodoo Engine

[Muligan]

Okay - I'll likely get flamed for this, but just wanted to share something that I learned from a long-time engine builder and vintage race guy. We were talking about hauling cars in/on trailers and he asked me if I knew to never leave the car in gear when hauling it. I said, "of course, it's bad for the transmission." He allowed as that is somewhat true, but that the real reason is that if the car is left in gear, it will rock back and forth a slight amount (even when cinched down with straps) and that if it's in gear, that slight rocking motion will be transferred to the engine through the driveline, causing the pistons to move ever so slightly up-and-down in their bore. He went on to say that such action can lead to weakened or broken rings and lands on the pistons.

I know that lots of us had our GT350s delivered by various methods - including delivery from the factory - so I have to wonder if there is any possibility that rings and/or piston lands (the area around the rings) are getting damaged on these engines during transport if left in gear.

Just my humble contribution - for the .02 it's worth - to this conversation.

I’m suprised they let you see the pictures. I had mine replaced at Koons in Falls Church and they did not show me any pictures or test results. But in the end I got a new engine. As for the transport theory, I’d say it’s interesting theory but one that can’t be proved.

I think the slight rocking of a tied down car would be, well, slight. And even if it moved the engine a tiny bit, the engine is supposed to turn and has oil in it, so I don't see the harm. I call "old wives tale" on that one.

Thanks for the information. I wonder whether a little corrosion in the cylinders from sitting caused damage to the oil control rings? I wonder how many of the oil burners are cars that sit a lot?

Well I know mine didn't sit. The day it arrived at the dealer I picked it up.

I took pictures of the Borescope images.
Remember this engine had 9500 miles on it.

I believe this is the Head, near a valves

Not sure but he was pointing out the metal chunks

Notice the oil pooling

This is the Cylinder wall

The tech that the rings did not seat properly Cylinder 2 was the worst, 3 was almost as bad and 1 was the least damaged.

He also pointed out that the engine is a different part number.

Said that some of the sensors had to be replaced with GT350R ones ???

GT350-H6088,

Did you add your name to the excel spreadsheet in Google Docs linked above?

No I did not. I will check it out

I bet Ford is not happy with these pictures being posted!

Why?

Manufacturers usually don’t like for people or competitors to see things like this.

Oh well, tough Shit. I spent a lot of money on this car, if there is a problem I have the right to post what ever info I got.

Who cares. It’s not Fords car.

This isn’t a secret people.

I sent in a request to edit the document. Let's see what the owner says.

Thats the first time i've seen any diagnosis regarding the oil consumption issue. Interesting

For sure we know there are different causes. I just was wondering whether engines that sit can have this problem.
