    Hi everybody, I am new here and just like an opinion and share my research results
    I got 1985 Landrover County registered new 1987 in NZ and have built it into a camper during the last couple years, will post some photos later
    Now, I know that the former owner (good mate) dropped an army 3.5 L V8 in it, there is no engine number on it so I have to go with its a fairly low compression rate motor
    I have done tonnes (years) of research and investigations on how to make this run better and bit more efficient without rebuilding the whole thing
    So I have now got standard Strombergs (very well tuned) carbs with K/N airfilters
    10 mm HT ignition leads
    Torque Master plugs
    Ignitor 2 magnetic electronic ignition
    60.000 HT E core coil
    And man, I got it going!!!
    Feels like I gained 50-60 ponies :D
    This is a NZD 400-450 bucks upgrade, so not super expensive either
    It is a big heavy truck as you know (with all camping gear its over 2.4 tonnes)
    And I do run 35´s on it (I know I know, but Im not a puritan)
    It still 4 speed LT95 so bit clonky
    But now, in third gear I push 60 up to 75 before 4th gear and feel it like it got more
    And right there is where the power sits (sorry no tachometer)
    Top speed will be way over 120 but have not dare that yet...
    Now to the problem:
    Since this remarkable upgrade, it has started a ticking sound
    I can move it around the rev range by changing the timing and I can even make it go away but losing power on that much retarding
    And it also have started pushing oil out the dipstick... NOT good...
    I think it always have done this since I have owned it (always had that burned oil smell), but now when it can rev so much higher the problem gotten worse...
    So whats you money on mates?
    1. busted can ring?
    2. worn pushrods/rockers?
    3. blocked release oil pressure valve?
    4. or just blocked up in general?
    5. other secret trick...?
    Grateful for any input and if anybody out there needs some more power out his 3.5 Liter Rover V8
    THIS IS THE RECIPE!!!
    Cheers
    /Rik.

    I would lean more toward either a head gasket for the oil and the cam is worn for the ticking.

    ok, I can see the potential in the cam for the noise, but how can a blown head gasket push oil out of the dipstick?
    Cheers for your reply mate

    I know nothing about your specific vehicle/ engine but I seem to recall from my long-ago love affair with engines that there’s a crankcase breather and if it gets plugged the only other vent is thru the dipstick hole.

    Wild card but might be worth checking.

    Good luck

    Sorry for the delay, anything that puts pressure into the crankcase, Plugged Breather as mentioned, plugged PVC valve, head gasket pressurizing the wrong vent hole, lots of things can cause crank case pressure.

    Thank you guys, am fairly sure now the ticking comes from a hydraulic lifter on the 5th cyl
    But could that cause the over pressurized crank case?
    And does it damage the engine to drive it?
    Cheers for your replies :)
