  1. thought I'd give you all an update to raise your spirits slightly if you are having RR troubles. Got the head off, massive crack between the valves on cylinders nr 4 and 5, luckily I had sourced a skimmed and pressure tested head from ebay for the princely sum of £80! Too good to be true? You bet it was, but I'll get to that. I also splashed out £22 on the valve setting tool - totally worth spending the money on I now realise. Got the head back on and all seemed to be going well, tightened the cam down slowly and evenly across all the bearing covers so as notto bend or stress it too much - this it would turn out was the least of my worries. Having eventually realised the cam chain tensioner was not fitted correctly I overcame that drama and fitted everything onto the engine with a nervous anticipation. Bled the diesel through and turned the key for it to not even try and fire, let alone start. Eventually it coughed and spluttered a little but wouldn't start. This was not the desired result after 3 days off work to rebuild the engine - I removed the rocker cover to find the cam drive sprocket had slipped and was about 10 degrees out, oops! On arrival the cam setting tool was put to use straight away and the marks I had made were actually not too far off. Again with the refitting of the rocker cover and inlet pipes, key in the ignition, still not starting but the farty splut spluts were more encouraging. At this point had I noticed the pin for setting the crank position was loose in the flywheel and required a joint effort of me wiggling the crank with a 22m spanner and swmbo pushing and wiggling the setting tool until it found its way all the way into the hole I would have been a happy man, however it was not to be. We were now cooking on gas and nothing could stop my amazing engineering prowess as I reset the cam for about the 7th time. Refit rocker cover, inlet pipes and turn the key... Also don't forget to remove the setting tool or spanner on the crank! Attempt nr 8 with the key turning part of the process. Oh my word, running on 2.5 - 3 cylinders it made an impressive smoke screen that would have hidden a battle ship! Accompanied by s loud knocking noise. My heart sank slightly more than I thought it was possible for it to go as I realised the timing was still wrong and valves were hitting pistons. Cue grown man crying like a baby. 'Maybe I got lucky and they aren't bent' was the deluded thought process I went through. Having now realised the setting tool needed the wiggling I mentioned above hte engine was locked in position and you guessed it, cam reset, rocker cover, inlet pipes, remove setting tool and spanner, turn key. Wow, a more predigious and vast smoke screen has never been produced, definately valve issues so nothing for it remove the head - again! Luckily in the process of stripping the head I noticed that the centre bearing of the cam had all manner of marks and scratches that weren't there before, turns out after machining the head the oil ways hadn't been cleared of swarf properly so I am now awaiting the arrival of a replacement cam and a new valve compressor (BMW valves are deep in hte head so you need a longer reach pushy thing to remove them!). Moral of the story - buy the right tool for the right job or avoid P38s? I'll let you know once I get it running as to whether all this character building was worth it...
  2. fear not me old chums, lifted the head slightly, swore a bit and got the tensioner retained properly. Fingers crossed its plain sailing from now on
  3. Evening Chaps, I am currently pretty much at my witts end trying to get the cam drive sprocket on to the cam. I've just had to change the head and followed the rave manual except for where it says use specialist tool xxx Being the pikey sort of fellow I am I don't have the correct (read any) specialist LR tools for releasing the cam chain tension, or setting the cam position. Whgat I did do was mark the cam, the cam bearing cap and the sprocket and made sure I haven't turned the engine. Domestic management helped guide the cam tensioner into the head which didn.t go well at first then it all seemed to click into place. The problem I now have is there seems to be too much tension and I can't figure how to get the sprocket onto the cam. It seems to need to move about 5 mm closer so I can get it on - basically what I am asking is am I being a girls blouse or is it more likely the tensioner has gone back together wrong? I'm pretty sure I know what the answer is going to be, but anyone with any experience/advice or fancies doing a range rover diesel head gasket in the bristol area I would look forward to hearing from you!!! Suddenly the push rod TDi engines seem quite user friendly!! thanks Matt
  4. I had a Seat Leon which had a similar issue, the sensor in the expansion tank is pants on these (both VAG vehciles). If the coolant is visually OK then i would say you are all good to go. FYI I cured mine by... well I'm not sure to be honest it just stopped playing up after a while.
  5. Sounds familiar, I had photos and witnesses and still my insurers lawyers caved in, makes me wonder who the other party were insured with now.
  6. Its F'ed anyway so if it was me I would pull the head off and have a look - if the bottom end is OK you will need to change the head gasket and either replace the head or skim, if the bottom end is dead its lighter to get out
  7. Oh, I asked someone at a 4x4 place in Swindon and they said the MOT rules had changed
  8. Having planned a head for once in my life I learned from the MOT man that there was a recent change in MOT law/standards and the rock sliders I have which bolt onto the chassis via where the hockey stick things mount is now an MOT failure. As one side has a healthy dose of rust in the sills, I was wondering if anyone could see a problem with just cutting off the old mounts and welding the box section in where the sills used to be? I realise the tubular sticky out bits would be slightly further in but I haven't got anywhere near off road other than a camping field recently coupled with it being an L reg 300TDi I'm not overly concerned about a few scratches or aesthetic anomolies
  9. thanks chaps, looks like I have a fun evening ahead of me!
  10. sorry to hi-jack the thread slightly but its relevant (ish). I need to do my head gasket thanks ot crumby plastic filler breaking, is it best to replace the head bolts with new stretch bolts? Also if not required is the tightening sequewnce the same? thanks Matt
  11. I used percussion maintenance techniques to free mine up, plenty and plenty of WD to start with thne whacking the cXXp out of it got it moving
  12. might not be a head gasket but the head will probably need to come off anyway. Have you done a compression test?
  13. how about stabilisers like you had on your first ever push bike, if you can weld then make up some thing that bolts to the side/chassis and extends a wheel several feet (metres) past the wheel track and it should stop you tipping over, super bodge but cheap and easy
  14. under what criteria has it failed? eg no point changing a MAF if its burning oil
