D3 and 4 are great cars when they are running - my D3 is at 440,000km now and I'm surprised its still going considering what its been through (especially recently). They can be expensive to keep on the road at this mileage, even with doing my own maintenance - I'd hate to have to pay someone to do it all!
Do not use any sealant on the rubber type gasket just make sure the top of the cylinder head is spotlessly clean. The workshop manual does say to put a small (tiny little smear) amount of sealant at the bottom edge in the corner where the cam caps touch the head. But I dont do this and most engines I have done never had any from factory. The new manifold has the gasket fitted with the bolts that have collars to keep the gasket in place while installing it.
Is there a recommended mileage that you should change the engine oil cooler? I have 240,000km on mine I’ve done the top coolant outlet in the last 15000km as I was very lucky in finding that one before damage happened. Thanks Paul.
There doesn't seem to be a set mileage that the engine oil cooler fails. The top coolant outlet though I recommend customers get it changed out at round every 70 - 80K.
I wish I had seen this video a fortnight ago! Got the red triangle and Restricted performance up on the dash on a New Years Day trip to the coast. Limped home and got a mechanic friend to do some diagnostics via the OBD 2 connector. P006a fault code. Removed and cleaned MAP and MAF sensors which did not fix the problem. What I did notice though first was the black oily residue sitting on the drivers side inlet manifold with a black stain on the engine cover acoustic mat. I wondered what that signified. I do now!! Have been quoted $3700 to fix as a ball park figure. Is that a fair price. Cheers and enjoyed your video.
$3700 if that is AU dollars then that price is way over the top. My price is not the cheapest at $2600, if you shop around you will see prices as low as $1800
Many Thanks for your reply Daz.@@aztech4x4mechanical It's Aus $$. I guess it all depends on what is advised to replace while the inlet manifold is removed. I'm following the comments on AULRO forums. It would be good to film the removal process of the inlet manifold. I don't think there is such a video on the youtube. I might try doing it myself if someone would demonstrate how it can be done. Pease do more videos on the LRD4. I'm keen to learn how to look after and repair these vehicles. Cheers mate.
