For any manufacturer to knowingly install faulty/inferior parts that leads to a failure like this is a chicken ***** move. ALL defective head bolts should be replaced with new gaskets and decked heads regardless of warranty costs.

I wouldn't say so. Continue monitoring your coolant levels. From what I have heard, there are engines with less mileage than 40k with the issue. It is somewhat random.

Mine went at 51,000 KM, about 32K miles. I filled it up with water once between the second last service and 31,000 KM and the last one at about 48,000 KM (from memory) but never thought to much about it being an issue at that stage.

You need to extend you MBZ basic warranty which is what the dealer should want to do since they make money on it. The Road Care Assistance just gets you a free tow to the dealer were the real pain begins.

My head bolts blew last week

Well this is becoming a more realy problem than I thought. Mine blew last week and now the engine needs to be rebuilt.

The dealer quoted me 42K canadian, MB headoffice will kick in half and i will 21K. My warranty is now over due to high Kms so it is all on me.

This seems ridiculous to me.

There was a guy on here parting out his entire car after it was wrecked, IIRC, but don't know if the motor was damaged...

I think it was Merc63. Not sure if the motor is even available anymore. At least we know that cases can happen up to 75k miles.

If MB is kicking in half, does that mean they are admitting to the fact it's really their fault. Otherwise, I think MB will deny the entire amount.

By the way, I thought a new engine costs roughly the same. Then what's the point of rebuilding it?

I think MBZ is wrong and should have gone the BMW M3 route and issued 100,000 mile warranties on these engines. Unfortunately they have not and we are stuck with the cards that have been dealt us. Since you have about 75,000 miles on the motor, I guess MBZ logic that a high performance engine should get 150,000 miles out of it so they are willing to pick up half the cost. Not the best outcome but it's better than them paying nothing. How long will they warranty the rebuild for?

Jonny N - Would you be so kind as to give your case it's own separate thread? Please post as many details as you can, particularly the events that led up the discovery of the problem. I'll put it in the sticky above and we can track it. IMO $21k for half of a rebuild is a bit of a rip...too high by any measure.

So, basically, anybody could be screwed at any time.

Great.

Let me be less p.c. about it. This is complete and utter bull****. It's a known defect for &*%sakes!

Time to start gathering other owners and hit MB with a class action suit. Any of us could be in this position at any time.

A wide press coverage of a broad based problem would cost MB/AMG a lot in reputation and undo a lot of the marketing efforts for the brand.

The best way out is for MB to cover the repair even after warantee expiration, otherwise the lawyers will uncover a class action opportunity.
We have to force their hand...

How expensive is a class action and how can we organize ourselves to sue them? This is annoying the heck out of me.

42K LOL!!!


My engine is gone to USA.. too bad, Im in Canada too..

I wouldn't fork over 21k for rebuild. Just buy a used engine and have it installed. Its not hard. I took my engine out in 5 hours with 1 guy.. Its pretty straight forward..

There is used M156s out there, you just need to search around...

I have documents for removing and installing engine if u need.

Nobody has answered the simple preventive maintenance question yet.

CAN YOU JUST REPLACE THE HEAD BOLTS, OR DO YOU NEED TO PULL THE HEADS AND REPLACE HEAD GASKETS TOO?

When the dealership replaces the bolts they also replace the gaskets. Not sure if it is a necessity or not.

The basic question is:

IF YOU SWAP ONE BOLT AT A TIME, DO YOU NEED TO PULL THE HEADS AND REPLACE THE HEAD GASKETS?

The simple answer is yes. No right answer is no. You don't need to but to remove the head bolts you have to remove the cams which requires special tools and special MBZ training. Part of the service bulleting also requires replacement of the lifters. Since you've done the tricky part (the removing the cams) it might make better sense to finish the full factory suggested fixed per the service bulleting.

Assuming you do not have a gasket failure, I am told this will work but is not at cheap as it may sound. See my post above.

Dealer replaces headbolts, lifts, head gaskets, intake gaskets, exhaust gaskets, plus any other torque to yeild bolts. Replaces the oil and coolant. Runs the engine through a cycle again and replace the oil one more time. Needless to say its a rather long parts list.
