  1. The pressure in the exhaust ports is always higher than the pressure in the valve cover. This forces exhaust gas to flow into the valve cover if there is a valve stem leak.  There is no way for oil to flow counter to this.

    As to oilways, there is only one oilway through the head gasket and it is not near any combustion chambers. In addition, any oil entering the combustion chamber (more likely via the rings) will be burned.  If so much was entering that it could not be completely burned, the engine would run on the oil and it would not be possible to shut the engine down through normal means.

    One Ten with electronics? 🙂 ... ok, I forgot the Radio ...

    Pretty much anything electrical can be damaged.  It sucks when you need to start replacing everything electrical in the vehicle. In addition to the high voltage, it is most likely pumping high voltage AC into everything.

    Being in Sweden, he is sitting on the battery.  It is not fun when one explodes and catches on fire.  There is nothing like a battery box full of hydrogen.

  3. IME, it does not stick long term to rusty surfaces either.  Sand blasted rough is the only thing I've seen make it past 5 years.  Now, this is on a vehicle that is used, not a garage queen.  Driven all winter in snow, salt and gravel. Normal polyurethanes or enamels are fine and don't peel off with standard surface prep.  The POR-15 does not like attaching to things.  If you want a durable under vehicle coating, I would suggest regular two part polyurethane or epoxy.

    It’s not any more difficult. 

    I disagree.  I've used it for 20 years and getting it to stay on for long term is very hard.  Sand blasted surfaces are the only thing I've seen it stay attached to.  3 to 5 years and it starts to peal otherwise.  Normal paint preparation does not work.  It comes loose eventually.

  5. I have one and know many people that have one.  It adds a slight self centering action under power.  You would only notice when driving back to back with the open diff. If the tyre pressure is less on one side, it pulls slightly to that side.

    What you are describing means something is wrong.  Did you ensure the diff internals were correctly arranged for a front install? Are the tyre pressure even side to side?

    :lol:His sunroof just cracked, so he’ll be heading their way soon I’m sure. His first 110 had a gearbox looms fault and he had to swap it for the vehicle he has now.

    It astounds me why people put themselves through the pain.  This is the sort of story I hear from every single new Land Rover owners I have talked to. It will be an interesting story in February to see how it fairs after a period of -40.
