According to my sources (PPC magazine and edition38 forum) the VW KR head is a really good design already, so doesn't need porting, people have done it before and it's basically been a waste of money. | |

your always looking to have a slightly off tan colour to the lavles and plugs for a clean burning engine, cyl 1 was a bit lean but 4 is what you want to see accross the boared. | |

I'm not too fussed BTW, the engine will be having a full rebuild, as will the head, so it won't be burning oil anymore. | |

second one is burning oil I would say, rest look fairly normal. Also what did the head gasket look like, had it gone anyway? | |

it would probably wash the whole area tho if it was coolant wouldnt it? i think they look ok realy, why was the head removed? | |

clean burning engine, possibly a little lean. have also seen engines that have similar colouring on the valves that have been burning some types of coolant. | |

What does this picture tell you about how the engine was running? |
