    Can't diagnose white smoke out of exhaustpipe

    I think it is definitely in need of a rebuild. The manifold is just loose which is why there is smoke coming out of it

    Can't diagnose white smoke out of exhaustpipe

    Here is a video of it running if it helps, idling at about 1000 rpm, and the smoke is quite a bit more white in person

    Can't diagnose white smoke out of exhaustpipe

    Thanks for your reply, i am based in Waterlooville, just north of Portsmouth. I bought the car as a full on restoration project, so I have never driven it, it had been sat in the Arizona desert for possibly decades. If i flush all the water and replace it, there does seem to be some sort of film...

    Can't diagnose white smoke out of exhaustpipe

    So i have done a compression test 1- 100 2- 95 3- 90 4- 95 5-90 6-90 So very low. As i said, it has a brand new head gasket, so could this indicate all the rings are gone? I also had to re grind all new valves in as 10 of them were bent, so perhaps I haven't done it well enough as it was my...

    Can't diagnose white smoke out of exhaustpipe

    Hi there, i've got a 260z with roundtops on, and it idles like a bag of spanners, and emits a ridiculous amount of white smoke out the back. Normally you would think this would be a blown headgasket, but it is a brand new headgasket, torqued down correctly. I have even tried draining all the...

    Can somebody explain to me how the float level affects air fuel ratio?

    I've heard a lot of people say that if you float height is set incorrectly that your engine will run rich or lean, surely the air fuel is dictated by the mixture screw and what needle you have etc? and that as long as there is fuel in the bowl the engine will just draw as much fuel as it needs...

    Difference between l26 and l28

    Hi there, Sorry if this has been asked before, i genuinely can't seem to find any info on it, maybe i'm searching wrong What are the differences between these two engines? I think i heard somewhere that the only difference was crank shaft, so a swap in crank shaft is all you need to turn it...

    Replaced flat tops with round tops off ebay, need help setting up

    Thank you! I will try all of this. The carbs visually look very very nice, but i think the throttle shaft may have a bit of play. I'll double check the float heights and throttle shaft later. The jet adjustment screws on both carbs were both wound down almost all the way, the rear one most so...

    Replaced flat tops with round tops off ebay, need help setting up

    Yeah i've got a Haynes manual. I think the carbs are missing a few bits, for instance they came with no springs, and the the arm that connects to the jet to adjust choke.

    Replaced flat tops with round tops off ebay, need help setting up

    No no not patronising at all. I really appreciate the honest advice. I've got a family friend that has worked on a lot of SU type carbs, I'll ask him to come and have a look. Thanks

    Replaced flat tops with round tops off ebay, need help setting up

    As title says, I have a 74 260z that came with flat tops, so i immediately changed them to round tops. The carbs look like they have been completely taken apart and steam cleaned, (i had to change both needles as they were bent), and I have no idea how to set them up even to start the car. the...

    Valve adjustment so far out I can move the rocker arms either side of the lash pads

    Hi all, This is my first time restoring a car and taking apart an engine, so i'm learning as I go along. Recently the notch that holds the camshaft inline with the camhaft gear sheared off and my engine lunched itself and bent most of the valves, so i've began to take it apart to rebuild, and I...
