  1. rocker cover leak through bolt

    Range Rover Mark II / P38
    I have a leak through the front outside rocker cover bolt on the right hand side of the car. Did some research, tried tighten the bolt up a bit as it was quite loose, having tightened it unfortunately it still leaks. Pretty quickly too, started the car and within a minute or two I can see some...
  2. Shims rocker arm pedistal

    Range Rover Mark II / P38
    Quick question, When, for example, 0.5mm is milled from the heads, how thick should the shims be under the pedistals? For some reason (the valves become lower in the engine), I think the shim shouldn't be 0.5mm. If someone knows the answer saves me from figuring this out, wasn't a fun job. ;)...

    Range Rover Mark II / P38
    Anyone had experience with aftermarket steel rocker arms that are offered for our engines?
  4. EAS rocker - manual height settings question

    Range Rover Mark II / P38
    This past summer I replaced the coils under the P38 with all new Gen-III air bags. Replaced a broken height sensor. Rebuilt the air compress and valve block. Everything works great... I think at least. The normal and extended settings work correctly. The EAS system only drops down to the...
  5. Rocker bolts snapped - dodgy torque wrench?

    Range Rover Mark II / P38
    Hi all Returning the car today I went to bolt the rockers on and two of the bolts sheered off, one on either side. After the first one, I found that there was some oil in bottom of the threads I hadn't cleaned out, so assuming that was the cause I made extra sure the threads on the other head...
  6. Hidden rocker switch function?

    Range Rover Mark III / L322
    Hi, I found a rocker switch under the steering wheel, almost next to the diagnostic socket in my 09 Vogue. What is it for? When I operate it (I feel a bit guilty as I would have told off my 9 year old son for pressing a button without knowing what it does!) the headlights come on, pumps start...
  7. What replacement Rocker Arms have you used ona 4.6 V8.

    Range Rover Mark II / P38
    If you have replaced your rocker arms have you used Genuine or some other. Would you be able to let list whether you fitted genuine or what make if not and how many miles since fitting them and any problems? Many thanks. Thought this would be a way to find out if any cheaper ones are safe to...
  8. Using used rocker arm assemblies from another engine.

    Range Rover Mark II / P38
    Has anyone ever used a rocker arm assembly from another engine in their engine? I appreciate engines wear at different rates but obviously a brand new assembly will not match wear of rest of engine so cant see an issue. I just want to rule out the rocker assemblys for a tapping noise so do not...

    Range Rover Classic
    Hey guys just wanted to see if anybody has had a problem with broken rocker arms on the 3.5 L motor. I just rebuilt the top end with a bigger cam .07 over factory. Put about 1,000 miles on rebuild when this happened. Sent from AutoGuide.com Free App

  11. V8 Rocker cover breather pipe totally blocked.

    Range Rover Mark II / P38
    Hi, cannot find this anywhere else so thought it worth a post. Noticed that the right hand rocker cover breather pipe that allows the rubber tube to connect to the plenum is totally blocked with something black or very dark brown. (Completely sealed. !) Before I take the rocker cover off to sort...
  12. rocker cover bleeding pipe causes high idle

    Range Rover Classic
    Hi, i have a classic 3.5 V8 with twin strombergs. After warming up the idle went up to 1500-2000 rpm's. I disconnected the rocker cover bleeding pipe from the right carburetor, and now it's running nicely at idle. Checked what happened if i just blocked the inlet at the carb where the hose from...
  13. Rocker arm identification

    Range Rover Mark II / P38
    Howdy all! I've been working on a head gasket replacement on my GEMS P38, and I think I have made a mistake. When I took the rocker arms off to clean them, I placed both of them in a bucket, and marked one to show which went to the left/right side of the engine. Unfortunately, I wasn't able...
  14. Land Rover p/n 602148 $10.00? wave washer, rocker shaft

    Range Rover Mark II / P38
    I finally put the heads on my 4.6 short block last night. ARP studs and all.. It went smoothly thanks to information floating around this very useful forum. Now I'm trying to piece all my valve train parts together to assemble that. I have replaced almost every part in the valve train that has...
  15. P38 4.6 knock from rocker cover

    Range Rover Mark II / P38
    Hi all, my 4.6 has started to knock from the drivers side rocker cover it seams. The knock is a constant and its not a ticking sound. It doesnt increase in volume or speed when the revs increase. I have changed the oil and filter this weekend which was thick and black with no water in it and...
  16. Stuck valve or bad rocker arm?

    Range Rover Mark II / P38
    I am replacing my head gaskets and I noticed one of my lifters are hitting the valley as there is a smooth mark right behind where the lifter comes up. It looks like when the cam pushes the lifter that is has nowhere to go so it just smacks the metal behind it. I'm thinking something is stuck...
  17. Rocker cover breather hose

    Range Rover Mark II / P38
    Hello all, was going to do a quick bit of maintenance tonight just by removing the rocker breather (Thor). Straight forward enough, however I can't get the **** thing off. Searched the site and there are plenty posts mentioning the removal and cleaning but none describing the how to (the...
  18. Air Suspension Rocker Switch -

    Range Rover Mark III / L322
    This may be a dumb question but I am curious about the air suspension rocker switch in my 05 Range Rover HSE. When the center button of the rocker switch light is on, is the suspension height "locked", or is it "locked" when the light is off. By default, the center button of the rocker...
  19. Rocker Covers, who knows

    Range Rover Mark II / P38
    what the tool/type of socket is required to tighten up the rocker cover bolts on a 2001 Thor? I've had a look around the web, however nothing confirming the type of tool or socket to be used. I'm sure many know that the bolt heads appear to be torque like as apposed to standard hex and will...
  20. What sounds like a top end ticking/rattle

    Range Rover Mark II / P38
    While returning home from work today I stopped at a set of traffic lights and noticed that while ideling in drive with my foot on the brake I was getting vibrations back through the cabin and could feel them in my foot while it rested on the brake pedal. When I got home I looked under the hood...
