Massive Merc V12 Engine Piston Damage

D-Fence · January 7th, 2007, 01:03 PM

Now that is a piece of work to do...

The guy repairing it really knows what hes doing!

Magnet · January 8th, 2007, 12:43 AM

Bloody hell, putting that back together must be fun.

Not something you'd really attempt with a Haynes manual.

STi Nut · January 8th, 2007, 03:24 AM

Yeah well the only engine that i have ever pulled apert and put together was a Toyota 4AG-E 16V. A quarter of that thing

Militant-Grunt · January 8th, 2007, 05:52 AM

Zainy Germans, that is a massive amount of work that the guy put into over hauling his engine.

Crazy Germans. images/smilies/biggrin.gif

AutoMX · January 8th, 2007, 07:41 AM

so thats basically mr. zonda engine sr.
i'm sure this is exactly what zonda owners will do when they hit 100 000+ images/smilies/lol.gif

Kudos.

That's a fair bloody effort!

And massive amount of work documenting it! I mean whole first page is just photos of engine in car from different directions images/smilies/smile.gif

Adunaphel · January 8th, 2007, 11:05 AM

Damn, that is a huge amount of work because ~~3 screws that held the rotor in one of the distributors failed~~ a mechanic forgot the screws that fixated the rotors in the distributors, leaving large amounts off unburnt fuel in the cylinders, which thinned the oilfilm between piston and cylinder, effectively making the engine run dry. With molten pistons as a result.

you dont want to attempt anything with a haynes manual....they are shite.

they describe everything like its a piece of cake, they dont even tell you what tools might be useful for the job at hand or anything and what usually happens is the job isnt that easy and its compounded by not having a fully stocked mechanics workshop

Yeah tell me about it. I wanted to replace the PCV valve in my Pathfinder, and the manual stated in steps.

1. Remove PCV valve

Neglecting to mention the number of emissions pipes that needed to be removed, along with the air filter, and the fact that the carby sat on top, meaning you could only turn the spanner 1/16 of a turn before it bumped against metalwork.

Yup haynes manuals are the worst chiltons are much better but nothing beats a factory shop manual.

Magnet · January 8th, 2007, 03:10 PM

Unfortunately, the shop manual for my car is the US version, which has a different engine.

D-Fence · January 8th, 2007, 03:51 PM

a) he changed the engine because it was completely destroyed but overhauled the new used one

b) this is the old v12 without turbos etc, i don´t think zonda uses this one (they use AMG versions of the new one) images/smilies/wink.gif

....I don´t know if the new one is based on this though images/smilies/wink.gif

Zonda uses the old 7.3 litre Merc V12, which I think is a bored and stroked version of the engine in question.

Just checked, it's called the M120. It's also in the CLK-GTR!

Ianspeed · January 9th, 2007, 01:33 AM

Damn, I love big engines. Can't wait till I can start building up one for my car.

Sweet.

I like the BMW v12 on the second to last page too. images/smilies/smile.gif

The_Finn · January 9th, 2007, 06:51 AM

good lord... now thats how you document an engine build. i wouldn't be suprised if it took him twice as long what with taking all the pictures

Salar · January 9th, 2007, 07:01 AM

The Zonda 7.3 Liter V12 engine was used in the SL73 AMG (R129) in the first place. It was also in the CLK GTR SS I guess, not really sure though.
