    not if oil cooler has a hole in it and oil and water are getting in through the valves as its a flat engine.

    Oil shouldn't get into the combustion chamber whether it has water in it or not.

    ok do you get water on your hand if held against tail pipe?

    and air bubbles where you fill the coolant that are constant? And increase with acceleration?

    Thermo and a pressure test then.
    Hope to have some results buy the end of the week fingers crossed.
    Getting a Thermo in by about Thursday would be good and see which of my local mechanics or radiator specialist have the time.
    Probably a good move prior to the approaching summer.
    Will check the dizzy and pull the plugs but may not be much to see with the sparks being only 3-4 Weeks old.
    See how we go aye? Y'all getting ya thermos in from JK's? Do u recon ghr would have a spare laying about for purchase?

    Misfire/backfire there is none.
    Maybe missfire but not bang, more hiss, when starting second time round. Upon eventually starting is when the smoke appears, not first time starting.
    Interesting discussion so far...

    OK end of day rule of thumb if you suspect water in oil check oil cooler before stripping engine down just remove oil filter then hoses then the bolt retaining oil cooler and replace oil cooler with engine rebuild.

    to test block one end submerge in oil and then pressureise with air and seeif bubbles rise in the oil.

    things were going good one on one but I have had a stroke and I can't handle multipul persons getting in on the act as my concentration is stuffed I have to appologise to you for not being able to get to the point / points I was aiming for, some people have buckets loads of money to throw at things I don't and i feel your in a similar boat. Or you just like to do it yourself.

    one other thing you could do is drain your fuel tank and check your fuel.

    hissing sound is an indication of a head gasket if its hissing near the head

    That would be the first thing I'd do.

    Then, depending upon the results, start looking elsewhere.

    Post up the pressure test finds, after you have it done. :rolleyes:

    Fuel is low and near empty. Will fuel up and get it out the red on preimo and see.
    Had a mate look at it recently when it first started playing up a bit. He thought fuel line or air/fuel mix possibly at a glance, which sparked the thread initially.
    Dunno what else.to comment on currently until I pull the sparks and air filter out tomorrow .
    Will report in again soon.

    Earlier in the year when my engine was first built it broke a head stud straight away and that made a hissing noise with a slight miss but exhaust was clear.

    I also find it hard to beleive the water could get past the ring in the sleeve and not weep to the exterior of the engine, although it is possible. If your coolant hasn't been kept up to date you could also have a hole in the sleeve but either way hole in sleeve or fluid getting into cylinder past head you will have pressure from the piston pushing air into your radiator system and you should see it where you fill the water at the blue or black cap in the form of bubbles that will increase with reving of the engine. if you have no bubbles in the coolant you probably don't have water getting into the cylinder.
