    looking for any advice??
    returning home from a Kombi meet last weekend in Tassie. Travelling through a winding uphill road. Suddenly a cloud of blue smoke,engine cut out. I managed to get the engine started again after a couple of minutes but there was a massive loss in power and the engine was running extremely rough (like a hairy goat). I got towed home on the back of a tow truck. I had her looked at by a mechanic and I have been told the engine has no compression in number 2, 3 & 4 cylinders and 70 PSI in number 1 cylinder. Any clues as to what might have caused this and what is the next step? Has this happened to any one else? cheers Jack

    What motor? 1600 type 1?

    Very weird to loose 3 cylinders quickly.

    Have you had a look?
    I am thinking loose head 1 & 2 side but weird to only lose 3

    Hi Barry
    I think the motor is a type 1 but I am not really sure how to know that it is a type 1?
    It is definitely a 1600 single port motor. On the front casting it has written
    HEEHO
    EN
    MEXICO
    I have had a bit of a look. All the rockers are functioning.
    I will go and check the head bolts next.
    Just thought I would ask for some feedback before I start looking further
    Thanks for your reply.
    Jack

    Hey Barry
    I just had a closer look ( motor still in the Kombi). It is a twin port not a single port. And yes it is a 1600.
    I cant check the head bolts until I get the motor out.

    That sounds more than heads. Taking it out is a good start but I would be checking more than the just the heads. Sounds more like the valve timing isn't right, as it it may have broken a tooth off the camshaft to crank gears. Purely contemplating the logic of the symptoms. If it was out the valves won't close at the right time and you wouldn't have full compression.

    Had this problem with a 71 1600 dual port back in the UK.

    Well it was only cylinders 1 and 2. Turned out the engine was over heating and the case studs in that side came out a bit (not uncommon)

    Can you start the engine?

    When I started mine after it happened and until I fixed it... The exhaust was coming out between the head and the barrels.

    Believe it or not when the engine warmed it... And metals expanded that stopped.

    I did a complete top end rebuild and can't remember what I used to refix the studs in the case with...... Was back in 1996

    By the way... I passed your bus in the Midland highway in the Thursday before Australia day... I thought you was heading to Swansea for the vw meeting... Unfortunately I didn't make it.. As I had family commitments in launceston

    Nice bus by the way...

    That could cause your motor to over heat and cause some problems for sure.

    AAAARRRGGGHHHH!!!. Glad you found a reason for something going wrong. Nothing worse that

    Amazing how something cheap failing can cause an expensive problem. Hope you get things sorted out with minimal fuss and expense.
