Will start the car up this weekend (I hope)
How to trash an engine in under 15min
Updates will come.
Have not even popped the hood yet
What happened Fred?.....Did she put a leg out of bed?(con rod out through the block?)
Car is still with hood closed But I will try to take it apart today... Have been just a bit mad at myself. This was NOT a mechanical error, it was totally my own fault and lesson learned is DO NOT START THE CAR FOR THE FIRST TIME LATE AT NIGHT BEING TIRED.
Took the engine apart today. Looks WAY better then expected. Have been really embarrassed over the failure 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.
Not to worry Fred....tiredness is worse than being drunk.... Most guys never wake up to learn this lesson when driving late at night.
Normally a headgasket, machine head and your sucking diesel once more. Looking forward to seeing this car back in action

Glad to hear that it wasn't worse, I thought for sure you were going to say that your rods were making friends with the engine bay. Keep up the good work!

Hi Fred,
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.

5 bar boost??????? Wow the rods and pistons will take this? What else is needed for that? Arp bolts gaskets etc?
My biggest worry about the 60X engines is the main bearing saddles and caps since its only a 2-bolt main and they have cracked under high power. 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!

(04-12-2015, 02:51 AM)Booster What turbo set up will you use to get 5bar??
You will need a custom boost gauge hahaha

Mahle do steel pistons with lower compression height so potential for cutting the block down save weight

Have a look. I don't know if they sell to the public but if someone contacts them they might get some decent information.

hello people, i´ve also installed a m pump on a om604, but this pump has a vacum switch to power off, as i had a crappy lucas pump, with electrical power down, how did you go around this issue, and have the pump on and off with the car key ?
thank you
The ignition switch normally has a vacuum switch attached. You can add an electrical vacuum switch controlled by the ignition if you don't feel like replacing the whole ignition switch assembly.

Find a wire that's hot in start and run. The egr vacuum valve should work fine.
I just mounted a new valve and got ignition power from the fuse box.
And yea guys...
The head is assembled and renovated from top to toe so I will start this car up really soon
I have a m103 oil filter housing with oil out to the turbo and the return is in the sump.

(11-04-2015, 05:22 PM)Hario No plugged fittings on the 604? I thought it came with turbo option also
No om604 where only n/a, only one from om601-om606 that never had a stock turbo version.

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. 3rd and 4th cyl have pressures down so it must be blown gasket between these two cylinders. I belive it was going to be blown anyway because we got 2bar for two seconds and that was all, it was the shortes test drive ever.

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.

(12-02-2015, 03:20 AM)erx 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.
And how it looks under the bonnet.
Damn man, that has to have been some crazy low down torque.
Yikes. So the head gasket blew as well as the rods bending?
Bit frightened about my NA 617 with a 5cm turbine and 7.5mm pump now
Off 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.
