Was such a rookie mistake but I really have to tell you...Screw all explanations that I have. It's simple, I was tired and missed a crucial part.
I forgot to fill up on water so run the car empty
yea I know, like the dumbest shit ever happened really but that's the truth.Now to the lucky part. Head is not cracked, pistons looks great, engine turns easy. Everything just looks good... So a new head gasket, machine the head straight, clean the prechambers and grind in the valves... Then it should fire right up again
It's amazing how strong those engines are really.

In that case, You will probably want to replace the piston rings, and give a quick hone to the bores. Mercedes engines are normally ready for service once more after this mini overhaul.

In that case, You will probably want to replace the piston rings, and give a quick hone to the bores. Mercedes engines are normally ready for service once more after this mini overhaul.
Surprisingly the bore is in perfect condition, the engine turns easy and bottom end looks like nothing ever happened
Thing is like this. If I have to pull the engine and take it apart, honing it and replacing the rings I'll rater get my self an om606 and sell the parts. I only have an 8mm 180cc IP on this one and if I wanted to make more work on this engine it has to be compound and A LOT of power.
Plan for next build is 8mm SS IP from Dieselmeken and aiming for 5bar of boost (70psi). However there is both time and money in a build like that so would be nice getting this one up and running so I can sell it and free up some cash

I won't be shooting for the moon with mine but for the sake of durability I'm planning on making a stout main girdle/bedplate to strengthen the bottom end. I wish these were a cross-bolted main, then it would be perfect!

I wish these were a cross-bolted main, then it would be perfect!
I don't know if the bottom end will suffer that much, billet main caps maybe. It's not that expensive to make, the expensive part is the line honing involved in making it work. And for sure 12.9-bolts down there. Maybe some epoxi in the block and so on.
You think the block will flex that much so there is need for a girdle? I don't really but sure it's fast to just cut out with the water jet.
So epoxy filled block with a main girdle, 12.9-bolts all over and 5bar of boost. Sounds like a plan guys
Only worry is the pistons. Cummins guys are running steel pistons at this boost and there is a reason for that. I'll think of something.

Yea boost gauge I have only reaches 4bar (56psi)
Think there is a 6bar (84psi) option available Will run (ohhh man this is far in the future) a compound setup with like a gtx3071r and a gtx4202r, this might change and maybe I need a 3076 instead of the 3071 to make the earth spin but we'll see.
Money is the real problem here though and would like to put it all in a w203 chassis instead. We'll see what happens

Mahle does indeed sell these for for the performance market of Cummins, Powerstroke and Duramax. These are still heavier then aluminum but they are very resilient to heat, can run extremely high clearance (they expand less) . I spoke with them about a year ago and the cost to even make these for use is beyond something they would be willing to attempt. Even for the big 3 diesel engines here you still talking almost 2K for a set..without rings.

How much boost was your 604 stock soft headgasket holding?

(12-02-2015, 02:24 AM)F.R.A.S Ohhh man sorry to hear. I did 2.5bar (35psi) for a couple of weeks of HARD driving. Then I swaped to the om605 steel gasket.
(12-01-2015, 05:12 PM)erx How much boost was your 604 stock soft headgasket holding? We put 606 modified manifolds, turbo and 6mm pump on 604 and headgasket was blown out after 30 meters driving with 2nd gear.
So mine was just old and needed changing anyway. I will not go over 2bar with stock 606 turbo, I don't know if I buy stock 604 gasket and go for silmple way or also swap to 605 metal gasket. Is gasket bore diameter needed to machine bigger like you did? Will the piston edges hit the gasket or what is the problem?

Yes the om604/5/6 pistons actually goes higher then the block so the pistons will hit the gasket. The organic gasket will never make it if you don't o-ring the block and that's more work then machining a gasket.

I took off cylinder head and found that pistons are not reaching to the block level, two pistons were about 3mm lower than block. I took pistons out and all four rods are bent, it was quite a surprise after one spoolup with 2nd gear. It seems that spool went up very fast and on low rpm and it killed the rods, turbo from om606 spooled up really fast on 2,2 engine, 2bar came instantly.

Damn man, that has to have been some crazy low down torque.

Yikes. So the head gasket blew as well as the rods bending?

12-08-2015, 01:29 AM #148Off topic slightly - nzscott looking at your consideration description you should feed the turbo into the supercharger. Supercharger is a positive displacement pump and only compresses a fixed volume so could be a restriction to the turbo. As it can't pull through more than the maximum the supercharger can supply. Whereas the air being compressed by the turbo can then be compressed again by the supercharger with less restriction. Hope this helps

Wouldn't forcing a supercharger to compress already compressed turbocharged air be asking a lot from it? The supercharger already has a parasitic drag on the motor/crank pulley when it's compressing atmosphere so think of the horses your losing.
I'm not saying it doesn't work - I haven't done it myself - I'm just sharing my thoughts.

It's called compounding, and if the supercharger is geared to provide for example 15psi boost. If a turbo is pushing 30psi into the supercharger, the supercharger output would be 45psi. So the supercharger only sees a 15psi differential across it, just like it would in a normal operation.
The reason why a turbocharger can't draw through a positive displacement supercharger is because the turbo's air flow requirement fluctuates with the turbocharger shaft speed (unrelated to crank speed), whereas a positive displacement supercharger's airflow requirement is directly proportional to crank speed.
Using a turbocharger to provide air pressure at the inlet of a positive displacement supercharger is very beneficial because rootes blowers run out of the ability to fill with air when they rotate at high speed. (Gear the SC for low down boost and the turbo will spool at high revs and pump into it bring its airflow back up). Much in the same way an engine's power curve drops off when it reaches peak air flow (atmospheric air pressure is unable to fill the void left by the rapidly descending piston within the decreasing inlet stroke window are rpm's increase.
