    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...

    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. ;)...

    Anyone had experience with aftermarket steel rocker arms that are offered for our engines?

    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...

    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...

    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...

    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...

    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...

    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

    Hi Can anybody tell me what paint I would need to paint the Rocker Box Covers as I believe they are a form of plastic. Thanks Tim Range Rover L322 2002 4.4 Petrol

    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. 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...

    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...

    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...

    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...

    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...

    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...

    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...
