I went to see a MB dealer to renew the cylinder head gasket which leaks towards the exterior, on my 260 E of 1988, 400 000km, I am the only owner of the car and gave a lot of attention to its mecanic and I do not wish to get rid of this car. Coolant has always been from MB.

He confirmed the leak but does not wish to undertake the repair. According to him and considering the age of the car, one risks to find either the cylinder head or the surface of the block corroded and thus to face very expensive repairs.

I have already changed cylinder head gaskets on other marks around 200 000 km but I do not have experience on MB at 400 000 km.

I believe that I will have to decide to do it myself.
What about corrosion, somebody does have experience and give me some hints?
What are the chances to find the cylinder head or the block corroded?

What is the reference of the tool for the cylinder head bolts (FACOM, MB or another mark)?

I saw in a technical manual that there are two types of screws (with and without washers) is it the same tool?

Is it posible to extract the pin on the chain guide without the inertia extractor?

Thanks for your help

we used to extract those using a bolt from the water pump housing and a stack of washers and or nuts.

i don't see why he would think that.

any well equipped machine shop can deck the block and mill the head. there are limits of course because it affects combustion ratio, and cam chain geometry and such.

i suspect there is another reason he doesn't want to do it.

I had the head gasket replaced on my 1989 260E with 360,000km last year and the was absolutely no corrosion there.
While the head is off, it is appropriate to check for valve guides as these are one of the problem area with this engine. Original guides wore more rapidely thanon other engine.
At least, go for new valve seals.
Sorry, can't help on bolts and tools.

Thank you all, for your replies. I think I will do it.
I will keep you posted
