  • I like how you were so nonchalant about it."Oh this is just a tool I made"

  • reverse bore, nice

  • I love fiat!

  • NICE DONE!

  • that was bmw M52 or M50 HEAD

  • no it's a BMW M3 E46 one

  • No its a Toyota Corolla head you dumb ass

  • hey that's an M3 E46 head isn't it

  • I know, but normally if you use other valve springs you try to fit them first before assembling the valve seals and the rest of the parts.

    Not that he doesnt make nice work!

    i'm an engine rebuilder myself, thats why i thought it was'nt realy logical.
