    I am officially pi$$ed off.

    Story so far
    Professionally rebuild engine
    Installed in the van and started up.
    Sounded like it didn't have an exhaust on.
    Shut down and discussed the problem with @zed
    Who thought the heat exchanger on no 1 & 2 wasn't sealing onto the head.
    We had a play repositioning the copper washers and re tightened the heat exchanger.
    Started up
    Sounded like it didn't have an exhaust on
    Shut down
    Zed went home and I flounced off indoors in a strop.
    Ordered new copper washers
    Waited a week until they turned up
    Fitted them
    Started up
    Sounded like etc etc
    Shut down
    Just refitted heat ex with TWO copper washers on each cylinder.
    Started up
    Sounded like etc etc
    Threw every teddy I could find out into the road
    Put a post on The Late Bay.
    Having a cup of tea while I await any ideas from you lot.

    Take the heat exchanger off, put a straight edge across the flanges to see if they are straight and parallel to each other.

    No, new exhaust but the heat exchanges exhaust flanges are very poor. I didn't feel any leaks from the heat ex to exhaust joints

    Bob. can you take it for a run, I mean do you feel it will be ok to drive?

    Some times a good run up to temperature will sort out minor noises etc, settle it in so to speak!

    Yup, but check them all, a good quality file and ten mins careful filing can get the flanges straight and true, I have done this a lot on older cars, sometimes had them milled by engineers

  12. Is it a 2 litre with hydraulic tappets? If so they take sometime to pump up and rattle like hell, until the oil gets in. Talking from my T3 CU engine experiance here ;)
     
  13. Flange :)

    This is the flange with a straight edge across the other one. If the straight edge goes onto this one the other one is very slightly out of true. Even with double copper gaskets fitted there were no witness marks on the gaskets when they came out.

  19. The HX was fine on the engine and not blowing before it was rebuilt.
    This side had a new head. As Bob says, I didn't get time to look into it.
    The cam needs running in so it's more or less start it "bang, bang" switch it off.
    Hate to say it, but maybe the HX is fine and the head isn't sealing?
