    My Head Hurts

    G'day to the "Brains Trust",
    I am standing here with a gallon of petrol and a match. Pontificating a small, well. You know.
    My problem, I have a 2004 Range Rover Vogue with a BMW M62 4.4l petrol motor that produces 210kw. This seems to be the killer for some reason.
    I have had a wet and dry compression test done on the motor & 3 cylinders are in need of work in the head department. Timing chain not making any noises but thought while we're in there, do the lot.
    Problem: NO ONE will touch the heads (have I contracted Monkeypox?). I have even tried looking for a reconditioned motor or exchange motor, might as well be looking for hens teeth or Rocking Horse *****.
    My 5 year trip around Oz starts in December (allegedly). Hence why I am standing here with petrol & a match. Isuzu BT 50 or D Max looking better & better. Has the Trust any solutions, suggestions or fixes. A mechanic quite some years ago when I had a similar head problem, removed the air cleaner, revved the motor to about 2000 rpm and sprayed water out of an atomizer bottle across the top of the air intake for about 4min, later the car was running better (steam allegedly removed the carbon from the valves).
    Does this still work or is the petrol a better option?
    TIA for all options suggestions and humour.

    MY Head still hurts

    G,day Laurie,
    It would cost me too much to get the wings fitted. Better off just on the ground and dance naked around it while its burning.

    on a serious note

    So on a serious note. Have you done a leak down test to see where the loss of compression is?

    Maybe take the rocker covers off and see if you have a sticky valve. Maybe run a oil flush. You have been using synthetic oil yes? Cause these engines run HOT. When I monitor engine temps on the highway it sits around 115c and around town I can see 135c.

    ^^ re running hot, the standard thermostat is a 104 deg. C item. I did the thermostat mod to change mine to an 82 deg C item.

    I’m hoping to get the timing chains and guides done by KLR Automotive real soon now.

    Hi Ron, If you have a scan tool plug it in and watch your engine temps. It's shocking

    I've heard they run hot to pass emission standards. I do have my old thermostat that I drilled a couple of holes in and it ran around the 80c mark. But I was worried it might be too cold and use more fuel. I changed it to a new one as winter was coming (2 years ago) might change it back as I have to do the water pump gasket anyway (little oil leak)

    Thanks FisherX,
    I'll give that a go once I google how to do it or ring the mechanic on Monday.
    What's the worst that can happen ?
    Yes I have running synthetic oil in the 3 years that I have had the car.

    Cheers
