Ah haaaa no advisories either. Defender Done good today
Tomorrow begins the rest of the Madman wiring... And i want to measure up for a fridge mount in the second row seating area. The question at the moment is centre behind the cubby box or an outer edge... choices... |

Well that is it the Madman has been installed and I love it, everything I could want in a multi-gauge. Except that is for the infernal beeping alarm that is telling me that Miffys oil pressure is poor and at hot idle dwindles to nothing at all...
Please pretty please don't let it mean a bottom end rebuild... Madman fitted and opperational. Click image to enlarge Madman displaying the bad news. Click image to enlarge Madman and Nanocom - Bad news 1. Click image to enlarge Madman and Nanocom - Bad news 2. Click image to enlarge So first step will be to make sure all the vehicle earths are tip-top as apparently the Madman gauge is very sensitive to bad earths. Next it will be to change the oils and filters and at the same time drop the sump (gasket could do with changing) and double check the pump bolt is A-OK. Just ordered oils from our good friends at Opie: https://www.opieoils.co.uk - Great price for quality oil. Also ordered gaskets and filters from LRDirect: https://www.lrdirect.com/home.php - Never let me down unlike other parts sellers... Here is looking forward to a good few hours under Miffy over the Easter break... Fingers crossed the weather holds. |

Yesterday I bought some oil additive to increase the viscosity as a stop gap to replacing the oils and filters this weekend. This morning I had a faintest amount of oil pressure showing on the Madman gauge, 0.9 bar.
Anyway I am glad the bandaid is sort of working. This had me thinking that the lack of oil pressure is unlikely to be the oil pump (unless the outer ring of the pump has split) as the pressure does build up quickly once the RPMs increase. It is just the idle pressure that is very poor. So, "death by a hundred cuts" maybe, I know there are a number of places oil is seeping out of a seal or gasket. Probably best case, but it is a starting point.
Just to perk up this thread this is from yesterday mornings dog walk/training; Click image to enlarge |

It has started... The oils have arrived (super service form Opie Oils), parts have arrived (LRDirect) and today an entirely new icon popped up on the dash that I have never experienced before in this country...
Click image to enlarge Yes yes I know I have an leak or two
Seriously, water in the fuel filter how often does that happen in the UK?!?! On to the job at hand. Engine oil flushed and draining as I type. Noticed it was very runny even when cold, but didn't smell of diesel... Odd... Next step sump off. |

Good news
Pump bolt is solid as a rock... I am now wondering whether it is worth checking the pump internals (cracked ring) as well since the sump is off.
Bolts in order, there is no other way to do this; Click image to enlarge Actually the sump is not off, it is loose but I need to remove the steering bar to squeeze it by so off the ramps and on to axle stands to increase the room between the axle and the engine. Then it is time to clean everything. Love days off |

Ok Next step done. Pretty much all clean and ready for assembly tomorrow morning. Amazing how long it took to scrub off 190k miles of crud from the sump.
Method: Getting the sump off on a defender is much easier than on a Disco 2. Chock wheels. Jack up the front end of the chassis and make safe on axle stands. This gives enough room to get the sump out over the axle. Remove one side of the track rod and move to one side. For this you may have to remove your diff guard. It is not necessary to remove the exhaust down pipe if you do not want to. Take the time to draw out the sump on card (use the new gasket as a template) to keep the bolt order safe. For ease whilst lying on my back I also wrote the bolt removal and refit order on the card too (they are not the reverse of each other). Looking at the dirty seal there did appear to be oil bypassing the sump gasket from the front left front corner. It also looked as if there was oil bypassing the bolts in a number of places too. To replace or not to replace... I finished yesterday with the thought that since the oil pump bolt is still tight after all this time I would leave it, but this morning I have decided (should the rain let up) to replace it as I still do not know if it was one of the bolts that had thread-loc from new. Better safe than sorry and all. One mistake so far: I did not order a gasket for the oil return pipe. ach well best break out the gasket sealer and hope... what a prat

Plan for today is pretty obvious:
get the sump back on, replace the oil filters and refill with oil. Should I get that done with minimal effort then it is on to;
Replace cam shaft seals (small leak there too), Search for other leaks and de-grease the block, Locate and clean vehicle earthing points, Batteries on charge over night (should have done that last night...) Then start her up, check for leaks and hope that this solves the low oil pressure issue (think we need a prayer emoticon Admins...) |

HA
Glad I am not the only one...
AT the moment all I can say is 1) Yes a hot cross bun would be great with my coffee and 2) I think the rain is slowing up a bit... |

Ok since I am down there and replacing the pump bolt I am going to have a look at the pressure relief valve as well, clean it, oil it and replace. Fingers crossed the spring is not broken. It is after all accessible.

Good grief that was a much longer day than expected
After deciding to replace the oil pump bolt this morning I am thrilled that I did. It did not have any thread lock, although apparently tight. Quick job whilst the sump was off for peace of mind.
I also dismantled the oil pressure relief valve as it was just there and boy am I glad that I did. Stuck!  solid
The threaded plug came out easy enough followed by the spring, but the actual value too the better part of 40 minutes to extradite from the oil pump housing. It looks like there has been some grit or debris had become wedged between the valve and the body of the pump. It was very stuck. You can see the score marks on the valve. They are not deep thankfully.
The other thing to check is the length of the spring, it should be 42mm but this one is 41.5mm. On this I tried to order a replacement, but it appears that unlike other Land Rover engines you cannot buy any of the valve components separately from the TD5 oil pump. Utterly sucks. So back in it goes and fingers crossed. At least it is free to work now. Click image to enlarge Next ont he list was to clean the pick up spout which had a surprising amount of gunk accumulated where the mesh meets the plastic housing.
The bolts form the gearbox through to the sump were an utter pain to get back in, but it is all back together again
Only other pain of the day was the demise of the Eezi-drain sump plug (originally from Difflock.com). I took it off to clean the seals and on refitting it just twisted apart and the odd thing is I only turned it in by hand. Obviously do not know my own strength. Gutted as it is an superb piece of gear. Thankfully i kept the original sump plug...
Back on the ground;
Tomorrow it is filters, oil and the camshaft seals to replace. Looking forward to it, really hope this sorts out the low pressure at idle issues. Guess the pressure relief valve could of been partially stuck open... Possibly... |
