K Series for or against

[mark]

They run good when they are working and have good power output for their weight ..................................BUT in the the past three years ive known about 4 of my friends own k series engined cars and only one of them got away with not having a blown head gasket

Many people say its down to lack of maintenance but all of them were well looked after and one of them was owned by a mechanics sister it was driven slow and very well looked after and it still went!
