[ML430-OFFROAD]

I called the dealer yesterday because i burned a quart in 1500 miles. The dealer said that we need to rering the engine. I do not know if you know this, but Mercedes extended the warranty on the ML's engine to 150000 and 10 years, so i don't have to pay, they just need it fo five days. I trust the dealer, so questioning their judgement is not the oint of this post, however you can comment if you'd like.

I just want to know what goes into reringing it, what kind things i should expect to see in performance. has anyone had experience with this/. I am just looking for knowledge on the issue

I know about the 150000 miles, there was a class action lawsuit but I can't belief that it is so easy to get your engine fixed. I have been fighting with MB since 2 years and they are doing nothing and my dealer is as bad.
Please keep us updated on this issue.

This is more to the point, it has the key words I would ask about:

"if the cylinder wall is scored too bad it will need bored"

"what about a ridge reamer to remove the ridge at the top of the cylinder"

and etc.

The cylinders on Mercedes, as well as most high end euro cars are plated, not cast iron bore. Nikisil and Alusil (sp) are the two main processes. This stuff is HARD. You can not hone it or use a ridge reamer in them without destroying the block. With these type of blocks, you just pull the pistons and throw new rings in there. You can clean the bore with special abrasive paper, but you should not have to.

These blocks do not wear, the rings wear. (Complete abuse withstanding)

Good to know, but do you know around what year that process started?

good info, thanks...
I will be most interested to see if there is a difference in performance, mpg, etc.
