    Howto change a head gasket on a 12v 3ltr M103

    When we did Paul's (JpsKiller) 3ltr Head Gasket we decided to do a howto. Its rather long so please be patient. I won't be able to complete the thread in one go as there are 40+ pictures and descriptions to go though. In the beginning take one 3 ltr engine and notice the oil sprouting from just...

    Need m103 rocker arms

    I need the old style m103 rocker arms as shown here. The surface which contacts the cam is slightly longer than the newer version and this surface is not welded on as the newer surface is. I need 12 of them with unmarked cam contact surfaces for my reprofiled cam. Mercedes do not sell this part...

    Help identifying m103 rocker arm types

    My camshaft has some wear, I have established that Brabus reprofiled the original M103 camshaft for more lift. My camshaft has the mercedes stamp followed by "103" and "22" below that, on the other side "AE2". My chassis number tells me that my camshaft is of the later, chilled cast iron type...

    Rebuilding my m103 Brabus 3.6

    I recently posted about hesitation around 2000rpm on my Brabus. When cylinder leakage was measured it ranged between 52%-64%, heard from the bottom end! So I've now stripped the engine down completely. The block has 2-3 thou of wear and so is shot. I'm getting a standard 300e block and having...

    M103 valve spring compressor?

    Hi, My car's been consuming a little too much oil for my liking of late so I've decided to treat her to some new valve stem seals ;). My current valve spring compressor can only be used with the head removed. Does anyone know of a readily available tool which will remove M103 valve springs...

    M103 Custome Turbo (Some Questions)

    After much research, I reckon the easiest way to squeeze horsepower from the M103 engine is to install a Turbo. The Mosselman kit is out due to high costs so I'm going the custom way. I am looking to improve low-end/off-the-line response and plan to boost no more than 6psi safely. Probably...

    300SL M103 (Head Job)

    Hello, My buddy has a 300SL with the M103 engine. Front seal is leaking and it burns oil. We're gonna take the head off for a valve job. Need some expert advise: 1. He thinks he wants to skim/shave off the cylinder head while it's off to get some extra compression. He's thinking 1-1.5...
