    Any members or other indies done this????
    I'm curious if it will be ok
    I have a 211 in at the moment that needs new liners. I'm not aware that the silicone aluminium liners can be refurbed so to speak
    And if they could is it really worth it or should I just go with standards liners?
    Obviously the aluseal is just a coating, but can it be refreshed

    Cheers

    Maybe this should be moved to the AMG section?

    If you use steel liners you need different rings to suit.

    The original ones can be polished so long as they are still within tolerance.

    Sunnen processing is usually good enough for the bores to be refurbished.

    This is the question. I have had a quote from my local engineering shop to convert the block to steel liners. But ideally I would refurb what is originally there!
    I have been quoted 225 plus vat per pot :eek:

    so ask them to measure them to find out how deep they have to go to get them in good order an then find out if mercedes do oversized pistons to match it .
    If that was a cast ion block I wouldn't have a problem to put new liners in it but being a alloy one I rather oversize the bores .

    It's not the issue. They are coated liners

    When we buy liners they come with matched pistons and rings, just depends on the manufacturer as to whether we use forged or cast,
    and the cost of course.

    Various way to get it done to be honest, the most popular way is for me is to Sunnen the bores and use Mahle piston/s where necessary.

    Darton liners with Mahle SLR Pistons on the E55 would be an option.

    All depends on the £$£$£$£$£$£$ available.

    The car came in consuming oil. A cylinder leakage test showed no issues so we put it down to the inlet guides/ seals. On removal pots 5/6 were cracked right at the top. I'm not sure how deep, but I think from looking it really is only the coating.
    The car is a 55k estate with 150 on the clock but utterly gorgeous in every way. I'm trying to weigh up wether it's worth buying and repairing.
