    I have posted before about the pain that is my surf!
    I had the Head replaced in May when i was on holiday in Cornwall. When i picked it up it had a pronounced power loss. I have subsequently had the turbo checked and now today the timing at a cost of about 250. It had a problem keeping the coolant in the engine and i had the cap and thermostat changed. The timing is correct. What else can be causing this powerloss?
    I can't really afford to get the head off.
    I can't really stress how fed up i am. If anyone fancies taking it on as a project let me know.
    Any other suggestions would be useful.

    You could have the compression checked, injectors checked and the fuel pump flow rate checked.

    I still think them guys in cornwall did something wrong, vacuum hoses incorrectly fitted, throttle actuator damaged, leak in the inlet manifold or exhaust manifold.

    I can't believe that the two things are not connected.

    When you say a pronounced power loss, how do you mean?.

    1. slow to pickup from stationary
    2. no mid range power
    3. low top speed

    Does the turbo cut in at about 1600rpm if you floor it or is it delayed. Does the engine hesitate or does it pull cleanly if slowly.

    What does it start like, easily or after lots of cranking. Is it smoke free or really smoky on startup. What is the smoke situation like on accelleration up a hill.

    Being low on power could be so many things.

    Cheers

      Have you had a look at another Surf to see if all the pipes and wires are on the correct bits, bring it round to me and we can compare it with my 2.4.

        It is slow from stationary and it has a top end speed of about 70 and at hills it just slows right down as soon as you get a bit of resistance.
        As for the turbo it seems fine. I can hear it boosting up and the light comes on. I had that pressure tested and it was ok.
        It starts almost imediately and there is some smoke but nothing excessive. It actually produces less smoke than before. Even when reved high it doesn't smoke.
        I spoke to trading standards who said that i need to get an assessor to write a report on the problems and the reasons. I have found out that this would cost approx 150 for the report and about 400 for dismantling the head and gasket. I can't risk 550 on an unsure outcome, I've already done that today on the timing.
        Its a Bummer!

          I have had a look at Barnaby's surf and sorted one of the water leaks, but he has a 2LT and I have a LTE, so could you look at these pictures and see if you can find a pipe that is located on the wrong connector.

          I removed the Turbo pressure sensor pipe because I'm sure that's on the wrong one, but need to sort out where all the others go.

            Sorry they did not come out very well, so could someone else post some pic's of their own surf to compare.

                Thanks Marky, but not sure if that is the 2LTE in the diagram, Barnaby's was different to mine.

                  Just read the postings in this thread, and sounds similare to probs I'm having since my head change, and wondered if you could help.

                  Turbo has never kicked in at 1600 (would be lovely if it did!) usually at 2000 before change, now it's about just over that.

                  On start up it fires up straight away, but there is now a lot of greyish smoke.

                  On pulling away, there is a lot of black smoke, and generally any time I put my foot down.

                  The smoke is a lot worse now than before the head change. Fuel consumption seems to be about the same, maybe slightly less, but hardly note worthy.

                  It is definately painfully slow pulling away now.

                  The guy who did the head is going to have a look at the timing next week, but any pointers I can pass on would be gratfully received!

                  I'd rather be scared to death than bored to death

                        Thanks for the Pics.
                        This is how mine is set up. Is this correct, should pipe 1 be attached to the Turbo sensor?
                        What are the sensors B & C?
                        Is it worth replacing these?
                        Also could it also be a faulty oxygen sensor causing the low power, if so where is it and where can i get one?
                        feeling a bit more positive now, thanks!

                          Straight off I can see a problem, see this pic and look at the pipes I have high lighted in white and blue on my engine. Then look at yours I think you will find that where the blue high lighted pipe is on mine you haven't even got a pipe there.

                            They were correct, but when Andy took the photos we had swapped them round.
                            Do you Know what those top two sensors are for. I might try taking the pipes of and checking for blocks.

                              Not 100% sure but they open and close via electrics to shut off/open the vacuum to certain things. From memory I think one of them is connected via a T piece to the turbo sensor and something else and should open and close as required.
