    RXT 255 is re-sleeving of cylinders? worth while?

    Hi,

    I wrecked my engine badly and basically need new cylinder, pistons and head after dropping a valve. Im quite sure it ran hot due to bad fuel but no biggie, back to project mode for a while with "fun" in the workshop instead of the water......

    Anyone knows if re-sleeving the cylinders on a 4-tec is worth while? new cylinder is 1800 USD approx but i can find sleeves on the net for around 100 USD each. I will get a workshop to remove and install the new ones and then hone into size (original pistons) but dont think it will be Nikasil treated then but just normal iron cylinders?

    Would that greatly reduce the lifespan of the cylinders and pistons and make the saving short term only and in the long run just shorten the lifespan of the engine? anyone out there attempting re-sleeve with success or should i just go for a new cylinder?

    oem $1800 "cylinder" is the whole block
    your block must be machined to take a new sleeve

    Yes it worth it to re-sleeve it, if the block is ok but the sleeve.
    The oem are not Nikasil not sure were you got that from.
    Find someone who has done one before. The old sleeve needs to be bored out first.
