lifters

  1. Rebuild engine- lifters thicking, overheating

    Range Rover Mark II / P38
    I try to keep long story short. 4.6 gems engine rebuild and before that totally stripped for cleaning, rework etc. After installing it back on: engine warmed up and then the lifters will start to make noise. Bought new front cover, waterpump, thermostat. Pressure tested the system with cold...
  2. Camshaft preload on lifters question.

    Range Rover Mark II / P38
    Qu for those of you who have changed the cam if that is OK? When there is talk of sorting preload on the lifters, (shim under foot of rocker arm) is this to compensate for wear on the rocker arm? From my simple brain I am guessing as you now have extra length so to speak on the push rod thanks...
  3. 05 HSE - Camshafts & Lifters

    Range Rover Mark III / L322
    So I have the dreaded ticking sound coming from my engine. Found out about the PCV hoses letting air and humidity in the engine making the lifters stick. Sure enough, I look at the hoses and they're like marshmallow. Changed the hoses to oil resistant hoses. Ticking is still there obviously and...

    Range Rover Mark III / L322
    So I have the dreaded engine ticking thing going on. I can hear it when sit there idling and it's driving me nuts. Browsed the forums, found out about the PCV hoses issue letting humidity in the engine and emulsifying the oil making the lifters stick. Checked them out and of course they were...
  5. RR Classic, noisy hydraulic valve lifters, what to do?

    Range Rover Classic
    80,000 miles ago, I overhauled my 3.9 litre RRover, but knowing next to nothing about the hydraulic valve lifters, I did nothing to them, thinking that little could be done to them, since they hydraulically are self adjusting---WRONG, they are noisy, tap, tap, tap! I think that I heard...
  6. P38 1997 4.6 HSE noisy lifters

    Range Rover Mark II / P38
    Hi all, My p38 recently has started to make a ticking noisy which to me sounds like hydraulic lifters, pushrods, rockers. I was told to flush engine out as sludge and varnish accumulates on the parts and restricts oil flow, hence the lifters not creating correct valve clearance. So i...
  7. lifters or exhaust leak

    Range Rover Mark II / P38
    I havean annoying tapping coming from the driver's side (rhd) of my 4.0 v8. I have changed the cam followers a couple of years ago and have only done about10k miles since so I don't think it is them. when it is cold it seems worse. when youfirst start it is constant, but after a few minutes the...
